Risk Mapping of Highly Pathogenic Avian Influenza Distribution and Spread
Provedor de dados: 7
Autores: Peterson, A. Townsend; ; town@ku.edu; Williams, Richard A. J.; ; ricw@ku.edu.
The rapid emergence and spread of highly pathogenic H5N1 avian influenza begs effective and accurate mapping of current knowledge and future risk of infection. Methods for such mapping, however, are rudimentary, and few good examples exist for use as templates for risk-mapping efforts. We review the transmission cycle of avian influenza viruses, and identify points on which risk-mapping can focus. We provide examples from the literature and from our work that illustrate mapping risk based on (1) avian influenza case occurrences, (2) poultry distributions and movements, and (3) migratory bird movements.

Provedor de dados: 70
Autores: Yanagi Júnior,Tadayuki; Silva,Éberson; Braga Júnior,Roberto A.; Lopes,Marcos A.; Damasceno,Flávio A.; Silva,Gleice C. de A. E.
Surface area (SA) of poultry is an important parameter for heat and mass transfer calculations. Optical approaches, such as the moiré technique (MT), are non-destructive, result in accuracy and speed gains, and preserve the object integrity. The objective of this research was to develop and validate a new protocol for estimating the surface area (SA) of broiler chickens based on the MT. Sixty-six Ross breed broiler chickens (twenty-seven male, thirty-nine female, ages spanning all growth phases) were used in this study. The dimensions (length, width and height) and body mass of randomly selected broiler chickens were evaluated in the laboratory. Chickens were illuminated by a light source, and grids were projected onto the chickens to allow their shape to...

Provedor de dados: 70
Autores: Pinheiro,Daniel G.; Machado,Nítalo A. F.; Barbosa Filho,José A. D.; Silva,Iran J. O. Da.
ABSTRACT The characterization of ventilation during the transport of broiler chickens is essential for identifying and characterizing the potential problems of a convective heat flow and its effects on the welfare and the health and production conditions of the chickens. The objective of this study was to evaluate the ventilation patterns in two layout models of a live transport load: conventional (LC) and alternative (LA) with spacers placed between the chicken transport crates. Computational fluid dynamics (CFD) simulations and wind tunnel tests were performed using small scale models. The results showed that the use of spacers between crates (LA model) modified the ventilation patterns and increased the wind circulation between crates. However, wind...

Autores: NAZARENO,AÉRICA C.; SILVA,IRAN J. O. DA; FERNANDES,DANIELLE P. B.
ABSTRACT This study aimed to determine a model to predict mean surface temperature of broiler chicks and live load microclimate conditions during transport by using neural networks. The research was conducted in the state of São Paulo, Brazil, by monitoring nine shipments with different density of boxes using an air-conditioned truck with an average capacity of 380 boxes. Fourteen chick boxes were chosen on each shipment, assessing five chicks per box. The mean surface temperature of chicks (MST) was measured with an infrared thermometer in both loading and unloading. By assessing the container microclimate (center and inside boxes), air temperature (T), relative humidity (RH) and specific enthalpy (h) were recorded; thereby, seventeen data loggers were...

Autores: Ponciano,Patrícia F.; Yanagi Junior,Tadayuki; Lima,Renato R. de; Schiassi,Leonardo; Teixeira,Vitor H.
The broiler rectal temperature (t rectal) is one of the most important physiological responses to classify the animal thermal comfort. Therefore, the aim of this study was to adjust regression models in order to predict the rectal temperature (t rectal) of broiler chickens under different thermal conditions based on age (A) and a meteorological variable (air temperature - t air) or a thermal comfort index (temperature and humidity index -THI or black globe humidity index - BGHI) or a physical quantity enthalpy (H). In addition, through the inversion of these models and the expected t rectal intervals for each age, the comfort limits of t air, THI, BGHI and H for the chicks in the heating phase were determined, aiding in the validation of the equations and...

Provedor de dados: 70
Autores: Abreu,Lucas H. P.; Yanagi Junior,Tadayuki; Bahuti,Marcelo; Hernández-Julio,Yamid F.; Ferraz,Patrícia F. P.
ABSTRACT Due to a number of factors involving the thermal environment of a broiler cutting installation and its interaction with the physiological and productive responses of birds, artificial intelligence has been shown to be an interesting methodology to assist in the decision-making process. For this reason, the main aim of this work was to develop an artificial neural network (ANN) to predict feed conversion (FC), water consumption (Cwater), and cloacal temperature (tclo) of broilers submitted to different air dry-bulb temperatures (24, 27, 30, and 33°C) and durations (1, 2, 3, and 4 days) of thermal stress in the second week of the production cycle. Relative humidity and wind speed were fixed at 60% and 0.2 ms−1, respectively. The experimental data...

ABSTRACT Environmental temperatures currently considered within comfort zone for broiler rearing may be misleading or even obsolete from actual values. Some factors such as animal genetics, nutrition and poultry management, mainly acclimatization to tropical and subtropical conditions, influence in determining the comfort zone for birds. This study aimed to evaluate the effects of five different thermal environments on animal welfare and rearing performance of broiler chickens, setting an ideal temperature range (comfort zone) for each of the first three weeks of poultry breeding. The chicks (375) were randomly placed into five climatic chambers set to distinct thermal conditions, being: one as recommended by the literature, another as stated by Cassuce...

Contribution of Meat Inspection to the surveillance of poultry health and welfare in the European Union
Provedor de dados: 5
Autores: Huneau-salaun, A.; Staerk, K. D. C.; Mateus, A.; Lupo, Coralie; Lindberg, A.; Le Bouquin-leneveu, S.
In the European Union, Meat Inspection (MI) aims to protect public health by ensuring that minimal hazardous material enters in the food chain. It also contributes to the detection and monitoring of animal diseases and welfare problems but its utility for animal surveillance has been assessed partially for some diseases only. Using the example of poultry production, we propose a complete assessment of MI as a health surveillance system. MI allows a long-term syndromic surveillance of poultry health but its contribution is lowered by a lack of data standardization, analysis and reporting. In addition, the probability of case detection for 20 diseases and welfare conditions was quantified using a scenario tree modelling approach, with input data based on...

Beziehungen zwischen Rohprotein- und Aminosäuregehalten in ökologisch erzeugten Ackerbohnen (Vicia faba L.)
Provedor de dados: 21
Autores: Witten, Stephanie; Böhm, Herwart; Aulrich, Karen.
In der Fütterung monogastrischer Nutztiere spielt neben der ausreichenden Menge an Rohprotein (XP) auch die Proteinqualität eine entscheidende Rolle. Die Proteinqualität hängt maßgeblich vom Verhältnis der Aminosäuren (AS) untereinander ab. Ein negativer Einfluss steigender XP-Gehalte in verschiedenen Körnerleguminosen auf das AS-Muster ist bereits beschrieben worden (Schumacher et al. 2011, Wang et al. 2004). Da ein hoher XP-Gehalt ein wichtiges Kriterium bei der Sortenwahl ist, ist es von noch größerer Bedeutung, eine solche Abhängigkeit zu erkennen.  Ebenso wie in der Literatur beschrieben, nahm in dieser Stichprobe der Gehalt einiger essentieller AS tendenziell mit steigendem XP-Gehalt ab. Unter diesen befinden sich die in der Monogastrierfütterung...

Refining proteins from green crops for high quality feed products for monogastricanimals and dairy cows
Provedor de dados: 21
Autores: Lübeck, Mette.
Green biorefinery concepts have the potential to become a suitable solution for production of organic protein-rich feeds from green crops. Different green crops such as alfalfa, red clover and clover grasses are studied as possible feedstocks for the development of an organic biorefinery system with refined proteins, ensiled press cake to be used as cattle feed and residual juice with potentials for fermentation of amino acids, lactic acid or other uses. A process was developed by which screw pressed juice from the freshly harvested crop was used for lactic acid fermentation to decrease the pH and precipitate proteins. These refined proteins have a favourable amino acid content and are comparable with soy proteins, especially for poultry where methionine...

Autores: Pegg, Venessa; Dyke, Kirstie; Philipps, Lois; Phillips, Scott; Pearce, Bruce.
A preliminary weight profile was produce for the organic silvo-poultry system on Sheepdrove organic farm. Seven batches (each of 20 hens and 20 cocks) were weighed over a two month period (January/February 2003). No current organic silvo-poultry weight profile was available but the weights achieved were found to exceed those of the nearest suggested profile (ISA 657) but were beneath the weights required for Sheepdroves markets. There was great and inconsistent variation between the batches and between sheds. This suggested that environment and management of particular houses could be having a large impact on final chicken weights.

ICOPP Report: Can the range contribute to the nutritional needs of organic pigs and poultry?
Provedor de dados: 21
Autores: Smith, Jo; Bauer, Christine.
On-farm habitats, including woodlands, agroforestry, headlands, field margins and agri-environment scheme options such as game bird cover strips, support a wide diversity of floral and faunal resources that may provide opportunities to enhance feed provision from the range for monogastrics. There have been many biodiversity studies of these habitats and this desk study will collate these data and information to test the hypothesis that the range can contribute to the nutritional needs of pigs and poultry as part of the CORE Organic II project ICOPP.

Provedor de dados: 21
Autores: Hörning, Bernhard; Trei, Gerriet; Simantke, Christel.
Es erfolgte eine Fragebogenerhebung bei 918 Biobetrieben und Vor-Ort-Erhebungen bei 92 Betrieben (70 Legehennen, 5 Junghennen, 17 Mastgeflügel).   Kenndaten: Von ca. 300 Umfragebetrieben hielten 2/3 unter 50 Hennen, nur 6 % hielten über 50 Stück Mastgeflügel. Einige Betriebe halten aber mehrere zehntausend Tiere.  Haltung: Die meisten Legehennenbetriebe verfügen bereits über Grünausläufe, viele auch über befestigte Kleinausläufe. Bodenhaltung im Stall dominierte. Verbesserungsmöglichkeiten bei den Haltungsbedingungen bestehen vor allem hinsichtlich Besatzdichten, dem Stallklima und der Einstreuqualität.   Herkünfte: Die größeren Betriebe setzen ausschließlich Hybridherkünfte ein (Rassehühner nur in kleineren Umfragebetrieben).   Fütterung: Gut die Hälfte...

Autores: Zapf, Katja; Damme, Klaus.
Auf dem Geflügelsektor werden in der Hähnchen- und Putenproduktion seit vielen Jahren von Erzeugerringen Betriebszweigauswertungen (BZA) durchgeführt. Für die Eiererzeugung existieren dagegen nur wenige belastbare Praxisdaten. Aus diesem Grund, wurden von Januar 2010 bis Dezember 2011 in 6 konventionellen und 6 ökologischen bayerischen Legehennenbetrieben produktionstechnische und betriebswirtschaftliche Daten für eine BZA „Legehennenhaltung“ erhoben. Von jedem der beteiligten Betriebe wurden Daten über den Zeitraum einer Legeperiode (20. – 72. Lebenswoche) erfasst.  Im Fokus der vorliegenden Arbeit stand die Auswertung der Leistungsmerkmale der beteiligten Biobetriebe. Die durchschnittliche Legeleistung je Anfangshenne (AH) lag in den ökologischen...

Effect of Flock Size on Dioxin Levels in Eggs from Chickens Kept Outside
Provedor de dados: 21
Autores: Kijlstra, A.; Traag, W. A.; Hoogenboom, L. A. P.
To decrease dioxin uptake by the general population the European Union (EU) has set limits to the dioxin content of many foodstuffs including eggs. Eggs from free foraging chickens are known to have a higher dioxin content as compared to confined laying hens and it is the question whether these eggs can adhere to current EU regulations. The aim of the study was to investigate parameters that are involved in the contamination of eggs from chickens raised under “organic” conditions.  Samples from 34 organic farms including soil and earth worm samples were collected between September and December of the year 2003.  Dioxin levels were assayed by GC/MS. Various parameters were collected by on farm interviews. Egg dioxin content varied between 0.4 and 8.1 pg...

Organic poultry production in Germany – key features, housing, feeding, breeds, perform-ance, health
Provedor de dados: 21
Autores: Hörning, Prof. Dr. Bernhard; Trei, Dipl.-Ing. Gerriet; Simantke, Dipl.-Ing. Christel.
Aim of the project was to find out key features of organic poultry production in Germany and to identify possible problems. Questionnaires of ca. 300 farms were evaluated and farm visits made on 100 farms. Hybrids were dominating on most farms. Most farms kept only small flocks. In bigger farms, aviaries were more common. Hens on most farms had access to pastures. In many cases, housing conditions or health prevention measures were not in accordance with current recommendations. Performance was low in many farms and indicators for feather pecking often found. Relationships between husbandry conditions and health or performance parameters were often found. Therefore, improvements seem to be possible on many farms.

Welfare of organic poultry
Provedor de dados: 21
Autores: Zeltner, Esther; Maurer, Veronika.
Organic poultry production has substantially increased in the last few years. On organic farms, welfare of poultry is enhanced due to enriched housing conditions as access to a  free range area. This may reduce feather pecking and keep the health status at least on the same level as on conventional farms. However, welfare of organic poultry may be further improved if: (a) laying hens are already reared in enriched systems that are close to the systems in the layer house, (b) a frequent and even use of the run, (c) selection of suitable genotypes especially in relation to digestive ability, and (d) effective prevention  and control of parasites.

Using local raw material for broiler feed in organic farming
Provedor de dados: 21
Autores: Roinsard, Antoine; Bordeaux, Célia; Lubac, Stanislas; Brachet, Mathilde; German, Karine; Juin, Hervé.
The article summarises the results of French and European research projects. It presents the vegetable protein market for animal feed, the nutritional values of various high-protein raw materials and the results of testing formulation strategies (diversification of raw materials and foraging). New raw materials are interesting, but not available and/or expensive. The tests reveal additional costs related to feed price and increased consumption indices. Formulation strategies with lower levels of protein in the finishing period make it possible to limit these obstacles. This article is mainly interesting for advisors. It is specific to organic farming, but not limited to a geographical area.

Høner med ansvar for ægkvalitet
Provedor de dados: 21
Autores: Hammershøj, M.
I projekt QEMP om bl.a. økologisk ægproduktion viste to høneafstamninger sig at lægge æg af meget forskellig kvalitet.     Mange faktorer har betydning for kvaliteten af hønseæg. Samtidig er ægkvalitet relativ i forhold til anvendelsen. Kvaliteten påvirkes bl.a. af fodring, tid og temperatur under lagring af æg, og hønens alder. Man ved, at forskellige genetiske afstamninger har forskellig ægydelse, skalfarve og skalkvalitet. Dog forudsættes æggenes indre kvalitet dvs. æggehvidens og æggeblommens sammensætning og indhold ofte at være ens uanset genetik.

The aim of this study was to examine the excrement load in outdoor ranges due to the outdoor run use of free-range laying hens (organic farming system) to quantify the accumulation of nutrients in the soil. The number of hens using the run (flock of 4,500 hens) were recorded (digital photographs; scan sampling interval 10 min, 5 hours/d, 23 d; 7 to 10/2003) and sward protection grids, positioned at different distances (2 , 6, 17 m) from the barn were used to get the amount of excreta (number and weight of droppings).  On average 9.8 % of the hens used the range out of which 69 % preferred the area close to the barn (0-17 m). Excretion rates per hen amounted to 12,4 g*hour, thus accounting for a share of 5 % of the total excrements of the flock. The...

Participatory breeding system for  laying hens
Provedor de dados: 21
Autores: Leenstra, Ferry.
Livestock breeds (and breeding systems) developed for  intensive production systems often do not perform as  expected in organic and extensive systems. For these  alternative systems animals need good social and  ranging behaviour, which is in general not necessary in  intensive systems with greater confinement for the  animals. Although this is the case in all the livestock  species (e.g. dairy cows, pigs and sheep), in poultry, the  differences between organic/free range and  conventional systems are comparatively large

Autores: Blume, Leonie; Hoischen-Taubner, Susanne; Kötter-Jürß, Martin; Löning, Jan; Renger, Anja; Vogt, Lukas; Sundrum, Albert.
Die Beratung zur Optimierung der Proteinversorgung von Schweinen und Geflügel benötigt umfassende betriebliche Daten. In einer Studie mit 56 ökologisch wirtschaftenden Betrieben ergab sich für viele Betriebe Verbesserungspotential hinsichtlich der bedarfsgerechten Fütterung und effizienten Nutzung von Nährstoffen. Die heterogenen Betriebsbedingungen lassen keine verallgemeinerten Empfehlungen zu sondern erfordern betriebsspezifische Strategien auf der Grundlage belastbarer Daten, um mögliche Synergieeffekte und Potentiale einer verbesserten Wertschöpfung erschließen zu können. Folglich sind Mängel in der Dokumentation und Datenaufzeichnung ein erhebliches Hemmnis in der Entwicklung betriebsspezifischer Optimierungsstrategien.

Die optimierte Rationsgestaltung in der Monogastrierernährung ist von zentralem Interesse in der ökologischen Tierhaltung, weil Imbalancen in der Inhaltsstoffzusammensetzung von Futtermitteln  zu einer verringerten Futterverwertung und gesundheitlichen Einschränkungen führen können. Es ist nicht hinreichend bekannt, in welchem Ausmaß Inhaltsstoffgehalte und Verdaulichkeiten zwischen einzelnen Chargen derselben Einzelfuttermittel schwanken. Zudem unterscheiden sich Öko-Futtermittel durch das abweichende Management potentiell von konventionell erzeugten Futtermitteln. Daher ist es notwendig, die Zusammensetzung ökologisch erzeugter Futtermittel zu kennen.  Um die Datengrundlage zu Inhaltsstoffen, Aminosäuren und ausgewählten B-Vitaminen in Öko-Futtermitteln...

Management factors affecting the use of pasture by  table chickens in extensive production systems
Provedor de dados: 21
Autores: Gordon, Susan H; Forbes, Michael J.
Whether chickens will make proper use of pasture is a problem experienced by producers of free-range and organic chickens. The aims of this project are to identify husbandry techniques and aspects of system design that encourage good pasture use. Two studies have been conducted comprising a winter and a summer flock. The aim of the winter flock was to examine the effect of outdoor artificial shelter on pasture usage. This was done for female Ross 308 birds grown to day 56, and ISA 657 birds grown to day 81. In summer, ISA 657 birds were grown to day 81. Treatments were either standard or enriched brooding, with pasture only or enriched pasture. Standard brooding was in a controlled environment house until day 42. Enriched brooding was in naturally...

Autores: Nielsen, Dr. Birte L.
Organic broiler producers are concerned that the occurrence of breast blisters is associated with perching.  This was investigated together with a comparison between two strains.  Four groups of each 60 Labresse broilers and 12 groups of each 60 i657 broilers where housed indoors in straw bedded pens (9.5 m2) and fed ad libitum with standard organic broiler feed.  The birds were subjected to one of three perch availabilities: 15 cm per bird (Labresse and i657), 7.5 cm per bird (i657 only), and 0 cm per bird (i657 only) with four replicates per treatment.  At 43 days of age 52 birds from each group were moved to outdoor housing facilities with access to grass-covered outdoor areas (each 9m by 22m).  The use of perches was monitored via video recordings...

EC Regulation 1804/99 requires organic sources of all components of feed in organic husbandry. Especially for organic pig and poultry nutrition it is not researched which components ensure the supply of amino acids.   In our previous studies in 2003 with laying hens with genetics of TETRA, the effect of a high percentage of linoleic acids coming from soybeans was demonstrated. The egg weight increased to an average of 73 g in laying week 38 (ANDERSSON et al. 2004). Consequently we tried in 2004 to reduce the egg weights    • by using the genetics of ISA XH   • by using components with less linoleic acid in the feed.   Using the genetics of ISA XH was one advisable result to reduce egg weights. In this actual study, the hens fed with soybeans laid eggs with...

Desk study – Optimising the synergism between organic poultry production and whole farm rotations, including home grown protein sources
Provedor de dados: 21
Autores: Gordon, Sue.
Over the past fifty years, most poultry in the UK have been managed in specialist indoor systems and excluded as a significant enterprise from most other farm types.  This meant that there was little information on how to integrate poultry into land-based systems such as organic production. This Defra project OF0163 aimed to assess methods of integrating organic poultry into crop rotations, taking into account the need to meet the birds’ nutritional and physiological requirements for health and performance, the recycling of nutrients between soil, plants and birds and practical limitations of the system.

Provedor de dados: 21
Autores: Canali, S.; Trinchera, A.; Intrigliolo, F.; Pompili, L.; Nisini, L.; Mocali, S.; Torrisi, B.
A six-year study was carried out in an organically managed orange orchard located in Sicily (Southern Italy) to assess the effect of compost and organic fertilizers utilisation on soil quality. Adopting a randomized-block experimental design with three replicates, four treatments were carried out. In treatments 1 and 2, two different composts (C1 from distillery by products and C2 from livestock wastes) were applied. The plots of treatment 3 were fertilized using dried poultry manure. The control  treatment was fertilized with mineral/synthetic fertilizers. In order to verify the hypothesis that composts and organic fertilizers improve soil fertility, soil quality was evaluated by selecting dynamic soil parameters, as indicators linked to C and N cycles....

Ökologische Geflügelmast - Lösungsmöglichkeiten für eine 100 % Bio-Fütterung
Provedor de dados: 21
Autores: Bellof, Gerhard; Schmidt, Eggert.
Das zentrale Problem in der ökologischen Geflügelfütterung ist die Bereitstellung von Futtermitteln mit ausreichend hohen Gehalten an essentiellen Aminosäuren – insbesondere Methionin und Lysin. Die beabsichtigte Umstellung auf 100 %-Biofütterung zwingt zum Verzicht auf bislang in der ökologischen Geflügelfütterung bewährte Eiweißfuttermittel aus konventioneller Herkunft (z. B. Kartoffeleiweiß, Bierhefe).   Um eine bedarfsgerechte Nährstoffversorgung zu erreichen, kann die Eigenschaft des Ge-flügels, die Futteraufnahme bis zu einem gewissen Grad nach der aufgenommenen Energie zu steuern, genutzt werden, indem den Tieren Rationen mit niedrigerem Energiegehalt angeboten werden. Durch die Mehraufnahme an Futter bei geringerem Energiegehalt kön-nen mehr...

Gibt es eine "bio-kompatible" Legepause?
Provedor de dados: 21
Autores: Zeltner, Esther.
Mit einer Legepause kann die Nutzungsdauer von Legehennen verlängert werden. In grossen Herden wird die Legepause mit Lichtreduktion und Änderungen bei der Fütterung ausgelöst.   In der Schweiz ist im Biolandbau, im Gegensatz zu Deutschland, die künstliche Auslösung der Legepause z. Z. nicht erlaubt, weil dies für die Hühner eine Belastung darstellt.

Die Umstellung auf 100%ige Biofütterung innerhalb der nächsten drei Jahre stellt eine große Herausforderung in der Monogastrierfütterung dar. Die in diesem Dossier vorgestellten Lösungsoptionen sind hinsichtlich ihrer Implementierungsmöglichkeit sehr unterschiedlich zu bewerten: Manche Optionen, wie beispielsweise die bakterielle Aminosäureherstellung, setzen noch erhebliche Forschungsarbeiten voraus, andere, wie die Verfütterung von bestimmten Silagen, sind bereits bewerte Praxis bei der Fütterung von Wiederkäuern, müssen allerdings erst noch auf Monogastrier angepasst werden. Während für die bakterielle Aminosäureherstellung entsprechende Bakterienstämme in ihrer Leistungsfähigkeit optimiert und geeignete Biosubstrate gefunden werden müssen, müssen bei...

In der ökologischen Legehennenhaltung sind sowohl stationäre als auch mobile Haltungssysteme beliebt. Für Neueinsteiger in diesem Bereich bietet KTBL in seiner Online-Anwendung "Wirtschaftlichkeitsrechner Tier" Planungsdaten zu den Kosten pro Ei für verschiedene Systeme an. Leider sind nicht alle Daten dort aktuell oder es fehlen sogar einige neue Stallsysteme komplett in dieser Datenbank. Ziel dieses Workshops ist es, den Informationsbedarf von Neueinsteigern in der Legehennenhaltung zu ermitteln und einen Überblick über das Thema auf einen Blick zu geben und die Bedeutung der wirtschaftlichen Perspektiven zu diesem Thema hervorzuheben. Darauf aufbauend können Datenlücken identifiziert und der konkrete Forschungsbedarf diskutiert und formuliert werden.

Phytochemicals and anti-nutritional factors in green biorefineries
Provedor de dados: 21
Autores: de Diego, Rocio del Rio.
Protein concentrates produced from green biomass such as grass, alfalfa or clover to be used as organic feed for monogastric animals might contain compounds that are anti-nutritional i.e. potentially harmful for the animals, as well as beneficial compounds. Both the anti-nutritional factors and beneficial compounds which can potentially be contained in the protein concentrates are described in this introduction section. Besides, the presence of specific anti-nutritional factors, i.e. mycotoxins and tannins have been analyzed in different protein concentrate samples as well as in samples from some of the fractions produced during the Organofinery process such as in the fresh biomass, press cake or green juice

Auf die Auslaufbepflanzung gerichtetes Verhalten von Legehennen bei unterschiedlicher botanischer Zusammensetzung und Bodendeckung der Grasnarbe
Provedor de dados: 21
Autores: Breitsameter, Laura; Isselstein, Johannes.
In organic laying hens husbandry it is desirable that the animals cover a proportion of their daily fodder intake by foraging in the outside run, e.g. by grazing. So far, however, few studies have investigated the factors which influence herbage intake of laying hens. In the present experiment we analysed the foraging behaviour of laying hens in the outside run at different conditions of sward botanical composition and of percentage ground cover of vegetation. The animals were taken to pasture on monocultures and a mixed plot of fourteen grassland plant species for three levels of period of stay in a rotational grazing system. By means of point sampling, we recorded scratching, plant pecking and ground pecking. Our results indicate that the factor plant...

Autores: Horsted, Klaus; Henning, Judith; Hermansen, John E.
The effects of strain, sex and age on live weight, slaughter weight and sensory characteristics of organically reared broilers in orchards are presented. A total of 450 broilers of three different strains (I 657, Light Sussex, New Hampshire) were reared in an organic research orchard. Half of each strain was slaughtered at 91 days and the other half at 120 days. All broilers were weighed and a clinical welfare assessment was made at slaughter. A trained sensory panel evaluated the breast meat in relation to flavour, smell and texture characteristics defined by the panel. At both 91 and 120 days of age the commercial breed I 657 was significantly heavier than the slower growing strains. Males were significantly heavier than the females across strains....

Samspel mellan hönshållning och oljeväxtodling
Provedor de dados: 21
Ekologiskt lantbruk utvecklas konkret genom att öka kunskapen om tillämpad ekologisk teknik, t ex hur man kan utveckla ett samspel mellan djurhållning och växtodling med syftet att minska på punktbelastningar och beroendet av externa resurser. Den tanken stod som modell för vårt försök med värphöns i mobila hus och som hade sin utevistelse i olika grödor, nämligen raps, solrosor, vårvete och höstvete. Utevistelse för höns i permanenta rastgårdar kan medföra överskott av växtnäring till marken och problem med parasiter och fothälsa för hönsen. För att minska dessa problem är det väsentligt att hönsen sprider sig väl utomhus. Reglerna föreskriver att marken ska kunna hållas väl bevuxen, varför höns oftast erbjuds utevistelse på en etablerad vall som har en...

Die Untersuchung der Gesundheitssituation der Legehennen von 20 Bio-Betrieben hat die Befunde vorhergehender Studien zum Stand der Tiergesundheit in der ökologischen Legehennenhaltung bestätigt. Es bestehen erhebliche Defizite in der Tiergesundheit, die sich auf ein breites Feld von Problemen beziehen (v.a. Federpicken, Befall mit Milben oder Würmern). Dennoch ist die Situation zwischen den Betrieben sehr unterschiedlich. Saisonale Einflüsse spielen ebenfalls eine Rolle. Es zeigt sich jedoch, dass eine Reihe von Betrieben auch über einen längeren Zeitraum eine gute Tiergesundheit vorweisen kann. Deshalb muss nach den Erfahrungen des Projekts prinzipiell daran festgehalten werden, Tiergesundheit als eine zentrale Managementaufgabe zu definieren und bei der...

Orsaker till skillnader i produktion och beteenden i olika inhysningsformer för värphöns har till stor del en genetisk bakgrund. Generellt är bruna genotyper som ej näbbtrimmas mer benägna till fjäderplockning och hackning än vita leghornkorsningar. Olika genotyper visade sig från produktionssynpunkt reagera lika på förändringar i fodersammansättning, men olika från djurhälso- och beteendesynpunkt. Med de näringsmässigt strängare KRAV-regler som förespeglas träda i kraft 2001 krävs från djurskyddssynpunkt sannolikt andra genotyper, men kraven riskerar att bli högre ställda än vad som är biologiskt möjligt att uppfylla.

Autores: Delics, Babette; Deerberg, Frauke; Deerberg, Friedhelm; Ruf, Manuel; Heß, Jürgen.
Die Freilandhaltung von Legehennen führt durch deren Ausscheidungen zu einem Nährstoffeintrag im Auslauf. Besonders der stallnahe Bereich ist durch eine erhöhte Akkumulation von Nährstoffen geprägt. Darüber hinaus zeigen sich Strukturelemente wie Unterstände oder Hecken, die als Schutzvorrichtungen für die Tiere fungieren, als kritische Bereiche. Diese daraus resultierende Eutrophierung kann infolge einer Nährstoffauswaschung (vor allem Nitrat) zur Kontamination des Grundwassers führen.

Turkish organic poultry sector: General evaluation and lessons from successful practices
Provedor de dados: 21
Autores: AKSOY, Tulin.
Considering Turkey’s success in conventional chicken industry which is around the frontlines in chicken meat and egg production in the EU, the aim of this article was to define the status and potential of organic poultry meat production in Turkey. Also we aimed to generate some advice to accelerate the progress in organic chicken meat production with a view to the successful implementations in EU and USA.  In line with the purpose, we will consider the results of some of our past research on the surveying of the rural poultry in Turkey and on alternative broiler experiments.   As commonly known, poultry production has been industrialized, and Turkey has a highly developed poultry industry. However, village poultry still exists in many developing countries....

Autores: Maurer, V.; Holinger, M.; Amsler, Z.; Früh, B.; Wohlfahrt, J.; Stamer, A.; Leiber, F.
Insects will likely play an important role as protein sources for livestock in the future. Many insect species are able to convert materials not suitable for human nutrition – or even waste – into valuable protein with a favourable amino acid composition for poultry and other livestock. A feeding trial with partly de-fatted meal of dried Hermetia illucens larvae (Hermetia meal) reared on vegetarian by-products of the pasta and convenience food industry was carried out in small groups of Lohmann Selected Leghorn laying hens (four rounds, 10 hens/round). Experimental diets H12 and H24 contained 12 and 24 g/100 g Hermetia meal replacing 50 or 100% of soybean cake used in the control feed, respectively. After three weeks of feeding experimental diets, there...

Einsatz der Mikroalge Spirulina platensis in der ökologischen Broilermast
Provedor de dados: 21
Die Fütterung der Tiere im ökologisch wirtschaftenden Betrieb ist besonderen Restriktionen durch die Rahmenrichtlinien (EU-Öko-VO, Verbände) unterworfen. Insbesondere eine bedarfsgerechte Eiweiß- bzw. Aminosäurenversorgung der monogastrischen Tiere (Geflügel, Schweine) ist erschwert, wenn auf konventionelle Eiweißfuttermittel verzichtet werden muss. Die kommende Anpassung der Richtlinien auf „100 % Bio-Futter“ stellt eine weitere Verschärfung in dieser Restriktion dar.   Die ausschließliche Versorgung von Mastgeflügel mit ökologisch erzeugten Futtermitteln (100 % Bio-Futter, Verordnung EWG 2092/91) erschwert die Rationsgestaltung zukünftig erheblich.

Contribution of feeds from range in organic broiler production
Provedor de dados: 21
Autores: Steenfeldt, S.; Horsted, K.; Sørensen, P.
A study with organic broilers with access to a large range area with herbs was performed and the effect of three broiler genotype (JA757, T851, SU51) with different growth rates and different feeding strategies (HP vs LP) on the animals' feed intake, growth and welfare was investigated. The results so far indicate that feed intake from range and animal welfare is dependent on type of allocated feed and growth rate of the broiler genotype. Thus, gait scores and foot and plumage condition showed that the fastest growing broiler genotype had some problems when fed normal broiler feed, whereas this was not the case for the other genotypes. The fastest growing broilers also ate more pelleted broiler feed compared to the slower growing breeds, which in contrast...

A longer life for laying hens is desired from an ethical point of view. Not only because the hens can be used for a longer period but also less male chicks would have to be killed at the age of one day. In large flocks of laying hens moulting has to be induced to prevent social instability in the flock. In this study, a method was investigated, to moult laying hens without too much stress for the hens. The chosen method with daily access to a bad weather hen run had no detectable negative effect on the behaviour of the hens. The moulting succeeded in improving egg quality and plumage condition.

Qualitätssicherung für Eiweißfuttermittel in der ökologischen Tierernährung: Sojabohnen und -kuchen
Provedor de dados: 21
Gesamtziel des Vorhabens  Die bedarfsgerechte Versorgung der monogastrischen Nutztiere mit Proteinen – speziell mit essentiellen Aminosäuren – hat in der ökologischen Tierernährung eine zentrale Bedeutung. Sojaprodukte aus ökologischer Erzeugung in Form von vollfetten Sojabohnen oder Sojakuchen können aufgrund ihrer hohen Proteinlieferung und –qualität entscheidend zur Eiweißversorgung dieser Tiere beitragen. Eine wesentliche Voraussetzung für den erfolgreichen Einsatz der Sojaprodukte ist eine Inaktivierung der antinutritiv wirksamen Faktoren mittels Erhitzungsverfahren. Erfahrungen aus der Praxis belegen, dass die bislang angewandten Behandlungsverfahren oft nicht den erforderlichen Erfolg aufweisen (Überhitzung oder unzureichende Erhitzung). Zudem kann...

Lactic acid fermentation for refining proteins from green crops and obtaining a high quality feed product for monogastric animals
Provedor de dados: 21
Autores: Santamaria-Fernandez, Maria; Molinuevo-Salces, Beatriz; Kiel, Pauli; Steenfeldt, S.; Uellendahl, Hinrich; Lübeck, Mette.
Nowadays, the organic farming sector is growing at a fast pace in Europe while needs to face the lack of organic protein sources and in particular, feeding monogastric animals is becoming more and more urgent. Green biorefinery concepts might become the suitable solution for the sustainable production of organic protein-rich feeds from green crops. In this context, red clover, clover grass, alfalfa and oilseed radish were studied as possible feedstocks for the development of an organic biorefinery system in Northern Europe. For this purpose, the green crops were processed into a nitrogen-rich protein concentrate, a fiber-rich press cake, and a residual stream of soluble nutrients (brown juice). The process, which involved a novel protein refining technique...

Do stocking rate and a simple run management practice inﬂuence the infection of laying hens with gastrointestinal helminths?
Provedor de dados: 21
Autores: Heckendorn, F.; Häring, D.A.; Amsler, Z.; Maurer, V.
The aim of this experiment conducted at four sites in Switzerland was to investigate the transmission and infectivity of the two main helminth parasite species of poultry (Ascaridia galli and Heterakis gallinarum) in outdoor runs with two different stocking rates.  Additionally, the inﬂuence of a simplemanagement practice (mowing of run) on helminth transmission was studied. Three run types were created on each site: runs C served as control (stocking rate 10 m2/hen, no management), runs B corresponded to runs C but were managed (10 m2/hen, management). In runs A stocking rates were doubled compared to control runs (5 m2/hen, no management). During two subsequent layer ﬂocks, a set of parasitological parameters (faecal egg counts (FECs), prevalence, worm...

Challenges in organic egg-production related to the nutritional quality of foraging material and introduction of 100% organic feeding
Provedor de dados: 21
Autores: Steenfeldt, S.; Hammershøj, M.
Organc hens have daily access to foraging material and the quality are important for egg-production due to varying contents of amino acids (aa) and dietary fibres (Hammershøj and Steenfeldt, 2005; Steenfeldt et al., 2007). Supplying organic hens with appropriate amounts of protein and aa can become problematic with the introduction of 100% organic feed from 2012. The interest in growing protein sources nationally has increased in Denmark in consideration of the environment. Growing soybeans nationally would reduce import. Present hen genotypes used in organic egg-production have high nutrient-requirement, so using genotypes with lower protein-requirements could have some interesting perspectives.

Autores: Løes, Anne-Kristin.
Laying hens are specialized for egg production, and high costs for slaughtering challenges the utilization of killed hens for food purpose. Alternative utilization, such as for production of meat and bone meal, may be hampered by lack of rendering plants. E.g. in Norway, hens are commonly killed by gassing on farm, and transported to a centralized incineration plant. The bodies contain high amounts of nutrients, which may be utilized as fertilizer. A study was conducted to measure the fertilization effect of residues after hydrolysis of grinded slaughtered hens, and to explore the decomposition of chopped killed complete hens. This paper presents the main results.

Naturlig modstandskraft er vigtig i fremtidens økologiske produktionssystemer for at opfylde markedets krav og forbedre den overordnede produktivitet. Men udviklingen af et robust immunsystem vil sandsynligvis være på bekostning af andre funktioner såsom vækst og reproduktion. I Organic RDD projektet SUMMER har man undersøgt tarmsundhed og immunsystem hos forskellige afstamninger af slagtekyllinger  med forskellige vækstpotentialer Deimmunologiske undersøgelser viser, at der er forskel på de basale immunfunktioner mellem afstamningerne. Den afstamning med det laveste vækstpotentiale SU51 ser ud til at have et mere robust immunsystem end den afstamning med det største potentiale JA757.

Application of lactic acid bacteria in green  biorefineries
Provedor de dados: 21
Autores: Lübeck, Mette; Lübeck, Peter Stephensen.
Lactic acid bacteria (LAB) have extensive industrial applications as producers of lactic acid, as probiotics, as biocontrol agents and as biopreservatives. LAB play a large role in food fermentation and in silage processes, where crops such as grass, legumes, cereals or corn are fermented into high-moisture feed that is storable and can be used to feed cattle, sheep or other ruminants. LAB also have great applications within green biorefineries, with simultaneous production of protein-rich feed for monogastric animals, silage or feed pellets for ruminants and production of lactic acid or specific amino acids. In green biorefineries, fresh or ensiled wet biomass is mechanically fractionated into green juice and solid residues (press cake), where the plant...

Alternative Fütterungskonzepte für Geflügel und Schweine  im Biolandbau
Provedor de dados: 21
Autores: Früh, Barbara; Leiber, Florian; Spengler Neff, Anet; Dierauer, Hansueli.
Alternative Fütterungskonzepte für hohe Leistungen im Biolandbau sind eine Herausforderung. Kurz- und mittelfristig fokussieren die Alternativen eine Äquivalenz zur konventionellen Fütterungspraxis.  Hierfür benötigt die Schweizer Biolandwirtschaft mehr Ackerflächen, um hochwertige Eiweissfuttermittel ökologisch und nachhaltig produzieren zu können. Partiell können Nebenprodukte die Eigenversorgung erhöhen. Langfristig muss der Biolandbau aus dem konventionellen Sog der Leistungssteigerung in der Tierhaltung aussteigen. Das bedingt eigene Leistungs-, Qualitäts-, Markt- und andere Konsumentenansprüche, damit der Markt für tierische Produkte weiter an Bedeutung gewinnen kann.

Untersuchungen zum Gehalt an ME und praecaecal  verdaulichen Aminosäuren aus einem Gemisch thermisch  behandelter Körnerleguminosen (LEGUMI-therm®) beim Broiler
Provedor de dados: 21
Autores: Nülken, C.; Kluth, H.; Abraham, U.
The objective of this study was to assess the effect of heating a mixture of grain legumes based on sweet lupins, faba beans, and peas (1:1:1, toasted “LEGUMItherm ®”; untreated: “LEGUMI-mix”) on the content of metabolisable energy (ME) and precaecal digestible (pc) amino acids for broilers. The mean of amino acid digestibility of LEGUMI-mix and LEGUMI-therm was 88 and 87 %. The ME content of the mixture ranged between 11.9 (LEGUMI-therm) and 12.1 MJ/kg DM (LEGUMI-mix). Both parameters were unaffected by heating.

Die Visionen, Standards und Richtlinien der Ökologischen Geflügelhaltung sind anspruchsvoll. Im  Vergleich zur konventionellen intensiven Geflügelhaltung sind hier Maßstäbe gesetzt worden. Sie hat  eine große Akzeptanz in der Gesellschaft und bei den Kunden. Die Praxis ist angehalten, die Visionen  umzusetzen: Richtlinien geben die Hürde vor. In einer immer mehr von der Lebensmittelproduktion  entkoppelten Gesellschaft („meine Milch kommt von Aldi“) versus einer Lebensmittelproduktion, die  immer weniger die ganzheitlichen Bedürfnisse der Konsumenten beachtet (Essverhalten und -kultur,  ideelle und ethische Werte) ist die Praxis aber nicht leicht.

Provedor de dados: 21
Autores: Trei, Gerriet; Synnatzschke, Martin; Hörning, Prof. Bernhard.
Aim of the study was to collect information about organic livestock farming in Brandenburg.  In comparison with other German states, organic farms in Brandenburg are  bigger and the soil quality is worse. Thus, beef-suckler and sheep production is more  important than dairy, pig or poultry production. Farmers mention problems with climate  (low rainfall), lack of agricultural area and problems with the marketing.

Eignung unterschiedlicher Herkünfte für die ökologische Haltung von Masthähnchen
Provedor de dados: 21
Derzeit besteht im Ökolandbau Uneinigkeit über die Zuchtziele für eine ökologische Geflügelzucht. Die auf einseitige Höchstleistungen gezüchteten Lege- bzw. Masthybriden sind anfällig für Gesundheitsstörungen und mit den zugelassenen Futtermitteln kaum bedarfsgerecht zu füttern. Maßnahmen wie die Zucht einer „Ökohybride“ oder die züchterische Bearbeitung von Rassegeflügel sind allenfalls langfristig möglich. Kurzfristig ist die ökologische Hühnermast auf die vorhandenen Herkünfte angewiesen. Als Alternativen zu den schnell wachsenden Masthybriden kommen langsam wachsende Hybriden oder Rassegeflügel in Betracht. Zu solchen alternativen Herkünften gibt es insgesamt nur wenig Versuchsergebnisse. Dies trifft umso mehr auf Versuche unter den Bedingungen des...

Free range and organic systems provide different circumstances for laying hens than closed houses or cages, where most hens are selected in. An enquiry and farm visits were done in The Netherlands, Switzerland and France in order to find out what genotypes are being used and how they perform. There are differences between countries, systems (organic vs free range) and groups of breeds. There is not just one genotype suitable for organic and free range systems.

Effect of breed suitability, system design and management on welfare &amp; performance in traditional &amp; organic poultrymeat (OF0153)
Provedor de dados: 21
Autores: Gordon, Mrs Sue.
Background  Over the past fifty years broiler production accounted for almost all of the meat chickens produced in the UK.  As a result, only broiler hybrids were available for use by UK producers, and these were not thought to be suited for use in some extensive production systems.  This meant that when consumer demand for extensively produced chicken meat increased in the late 1990s producers were unable to quickly identify and source the most suitable hybrids for UK conditions.  Furthermore, systems of extensive production were still being developed, and little was known about design and management factors affecting range usage.    Project OF0153 aimed to characterise breed suitability for extensive production (free-range, traditional free-range and...

Kansen voor pluimveemest in de gehele biologische productieketen
Provedor de dados: 21
Autores: Nauta, Wytze J.; Staps, J.J.M.
Deze brochure schetst de mogelijkheden voor verbetering van de afzet van pluimveemest in de biologische productieketen. Basis hiervoor vormt het project Kippenmest en Kringloop dat in de periode 2007 - 2011 door het Louis Bolk Instituut is uitgevoerd. Pluimveehouders in Nederland zijn vaak weinig grondgebonden. Daarom moet de mest worden afgevoerd. Afzet is echter niet altijd eenvoudig. Dit komt omdat de samenstelling van pluimveemest niet optimaal is. Vooral de relatief lage N/P- verhouding speelt een goede afzet naar de akker- en tuinbouw parten. Kansen voor Pluimveemest toont dat er goede mogelijkheden zijn om tot een gunstiger N/P-verhouding te komen via de voersamenstelling. Ook via andere wegen kan de afzet van pluimveemest worden verbeterd. Dat kan...

Applied research as interplay between farm and group level: What attracts laying hens to the hen run?
Provedor de dados: 21
Autores: Zeltner, Esther; Hirt, Helen.
On farm research is well established in organic farming. The holistic approach considers the complexity of a farm and the findings will be implemented immediately. As the experiments are often performed on single farms the results are difficult to transfer to others. Controlled experiments on group level with representative samples investigate single factors and lead to reliable and well-founded results. However, they are often far away from implementation. Applied research requires interplay of on farm research and controlled experiments. A series of ethological research work should show how this interplay may take place.

Mussel shells as an environment enrichment and calcium source for floor-housed laying hens
Provedor de dados: 21
Autores: Alm, M.; Tauson, R.; Wall, H.
Feather pecking is still a behavioral problem in laying hen flocks, resulting in impaired welfare and economic losses. Environment enrichment, e.g., providing access to litter, to increase foraging behavior in laying hens has been shown to decrease feather pecking. This study investigated the effect of spreading crushed mussel shells (particle size 10 to 20 mm) in the litter area as an environment enrichment and source of calcium for layers receiving a commercial feed and for layers given a feed with 40% less calcium. These treatments were compared with a control involving hens given the commercial feed, but no mussel shells in the litter. The study included 900 Dekalb White layers housed in a single-tier floor system during a production cycle (20 to 72 wk...

ORGANIC POULTRY PRODUCTION SYSTEM AND MEAT CHARACTERISTICS
Provedor de dados: 21
Autores: CASTELLINI, prof C.
The effect of the organic poultry production system on some qualitative characteristics of the meat is reported. The effect is mainly due to the greater age and physical activity of animals but it is largely modulated by the farming protocols used e.i., genetic strain (fast and slow-growing strains) and pasture availability. Due to economic reasons and chicks availability, generally fast or intermediate growing chicks are used. Such animals are not adapted to the organic system and health and welfare problems caused by leg disorders and lameness are recurrent. Nevertheless, compared to conventional chickens, the carcasses have higher breast and drumstick percentages and a lower level of abdominal fat. Even the physical-chemical characteristics of the meat...

Ekologisk slaktkyckling på hemmaproducerat foder och bete efter nöt
Provedor de dados: 21
Trots att konventionell kycklinguppfödning idag på många håll inte är överensstämmande med idéerna bakom ekologisk djurhållning (t.ex. benproblem och cikulationsrubbningar, preventiv medicinering, ingredienser till foderrationen och året-runt uppfödning inomhus), finns det fortfarande knappast någon ekologisk kycklinguppfödning i Sverige. Projektet syftar till att bidra till att utveckla ett ekologisk system för svensk kycklinguppfödning.

Poultry studies have measured nutrient values of manure in slow growing meat birds at about day 81 when fed typical broiler rations versus “Label Rouge” rations. Nutrient (N, P, K) balances were constructed to assess the viability of integrating poultry production within a theoretical organic rotation. The readilyplant- available nitrogen in manure from Ross 308 birds fed either presumed non-limiting rations or Label Rouge rations was within the range reported for intensive broilers. For ISA 657 birds, the manure readily-plant-available nitrogen...

Fulfilling 100% organic poultry diets: Concentrates
Provedor de dados: 21
Autores: Crawley, Kenny; van Krimpen, Marinus.
The main dietary challenge for poultry producers is ensuring that feed fulfills the nutrient requirements of poultry, in particular with regards to protein and the correct amino acid profile. This is a particular challenge for organic poultry producers as the use of synthetic amino acids is not allowed. There has been a derogation from the EU Organic Regulatory Board to allow organic pig and poultry producers to include up to 5% non-organic feed within their rations to assist in meeting the nutritional requirements of the animals. This derogation was due to finish at the end of December 2014 but has now been extended to 31 December 2017 when it will become compulsory under EU Regulations (EC) no 889/2008 to provide all organic livestock with feed derived...

Een ongewenst hoge aanvoer van mineralen zou een nadeel kunnen zijn van buiten lopende kippen. Als onderdeel van het project ‘Uitloop Gezond en Groen’ , van 2006 tot 2008 uitgevoerd door de Biologische Pluimveehouders Vereniging, Agro Eco, Louis Bolk Instituut en Ringadvies, zijn in de uitloop van vier bedrijven bodemmetingen gedaan aan met name fosfaat, stikstof en zware metalen. Daarnaast is gekeken naar de opvang van mineralen met strooisel in de uitloop en zijn fosfaatbalansen van twee bedrijven opgesteld.  Er is sprake van aanvoer van mineralen: nabij de stallen worden hogere gehaltes aan fosfaat en zware metalen gevonden dan verder weg. In de loop van de twee jaar kon echter geen toename in fosfaatgehalte van de grond gemeten worden waar dat uit...

Review: Towards the agroecological management of ruminants, pigs and poultry through the development of sustainable breeding programmes. II. Breeding strategies
Provedor de dados: 21
Autores: Phocas, F.; Belloc, Catherine; Bidanel, J.; Delaby, Luc; Dourmad, J. Y.; Dumont, B.; Ezanno, Pauline; Fortun-Lamothe, L.; Foucras, G.; Frappat, Brigitte; Gonzalez-Garcia, E.; Hazard, D.; Larzul, C.; Lubac, S.; Mignon-Grasteau, S.; Moreno, C. R.; Tixier-Boichard, M.; Brochard, M.
Agroecology uses ecological processes and local resources rather than chemical inputs to develop productive and resilient livestock and crop production systems. In this context, breeding innovations are necessary to obtain animals that are both productive and adapted to a broad range of local contexts and diversity of systems. Breeding strategies to promote agroecological systems are similar for different animal species. However, current practices differ regarding the breeding of ruminants, pigs and poultry. Ruminant breeding is still an open system where farmers continue to choose their own breeds and strategies. Conversely, pig and poultry breeding is more or less the exclusive domain of international breeding companies which supply farmers with hybrid...

100%-Biofütterung mit Rapskuchen und heimischen Körnerleguminosen bei der Fütterung von Legehennen verschiedener Herkünfte
Provedor de dados: 21
Autores: Rahmann, Gerold; Holle, Romana; Andresen, B; Andresen, C.J.
Rations of 100% organic and local origin were tested. Up to 18% of thermally proc-essed rape cake was fed in different rations to two groups of laying hens. Faba beans, Vicia sativa and blue lupines were used as protein supplements to create a feeding ration. High vicine and covicine contents, especially in Vicia sativa, led to a refusal of some food rations. No ration has been found suitable for daily use. Chicken fed with a rape cake ration laid eggs with a positive fatty acid pattern, which is favourable for human diets.

ORGANOFINERY: A biorefinery for the production of organic protein rich feed for monogastric animals
Provedor de dados: 21
Autores: Fernandez, Maria Santamaria; Uellendahl, Hinrich; Lübeck, Mette.
Nowadays, the organic farming sector is rapidly increasing in order to meet the increasing demand for organic products. However, the scarce availability of organic feed for monogastric animals together with the lack of organic fertilizers are challenging the development of this sector. In this context, a Danish project called Organofinery is focusing on developing a green biorefinery platform for the production of organic protein-rich feed for monogastric animals, of biogas and of organic fertilizer.  In the Organofinery concept, the freshly harvested green biomass is separated by a screw press into a green juice and a press cake. Soluble sugars contained in the green juice are fermented by specific lactic acid bacteria, leading to a drop of the pH and...

Production systems for organically managed laying hens are continually being further  developed with the result that a large number of production-optimised systems are  now available. In order to compare the economic efficiency of these systems, performances  under commercial conditions were recorded to assess investment and labour  requirements as well as other key figures. Comparing production costs per sold egg,  aviary systems performed better than on-floor barn systems from 3000 bird places  upwards.

Ved at vælge grovfoder i den økologiske ægproduktion, som har et højt indhold af karotenoider eller indhold af de rødlige karotenoider, f.eks. violette gulerødder eller grønkål, kan æggeblommens farve påvirkes i en positiv retning. Desuden kan grovfoderet bidrage til et øget indhold af sundhedsgavnligt lutein i æg.   På sigt vil øget viden om karotenoidindholdet i forskellige foderråvarer og grovfodertyper kunne bidrage til, at en ønsket blommefarve kan nås og bibeholdes på et stabilt niveau.

Debates on culling day-old male egg type chicks are constantly growing. The current study investigated the performance of two dual purpose breeds in a mobile production system under organic conditions. 509 Lohmann Dual (LD) and 505 Lohmann Dualexperimental (LDex) day old chicks were reared in two mobile stable barns as hatched. The cockerels were slaughtered on day 70, 80 and 85, the hens remained in their respective mobile barn for a prolonged laying period. Average bodyweight of cockerels at d 85 was 2650 g in LD and 2176 g in LDex. In 68 weeks of production, an average LD hen produced 289 eggs whereas it was 307 eggs in LDex. The performance of the dual purpose breeds is not comparable with those of specialized hybrids however it may still be sufficient...

Farm level factors associated with feather pecking in organic laying hens
Provedor de dados: 21
Autores: Bestman, Monique; Wagenaar, Jan-Paul.
Farm-level factors that could be associated with feather pecking of layers kept in organic farming systems were monitored in 63 flocks from 26 farms located in different areas of The Netherlands. Data on housing and management practices were  collected and plumage damage as a measure of feather pecking was scored at 50 weeks of age or older. No or little plumage damage was found in 18 (29%) flocks, moderate damage in 12 (19%) flocks and severe damage in 33 (52%) flocks. A high percentage of hens in the flock using the outdoor run, a young age at purchase and an increasing number of cockerels present in the flock were found to significantly decrease feather pecking damage at 50 weeks or older. Factors associated with increased usage of the outdoor run were...

Applied research as interplay between farm and group level: What attracts laying hens to the hen run?
Provedor de dados: 21
Autores: Zeltner, Esther; Hirt, Helen.
On-farm research is well established in organic farming. The holistic approach considers the complexity of a farm, and the findings can be imple-mented immediately. As the experiments are often performed on single farms the results are difficult to transfer to other locations. Controlled experiments with animals on group level with representative sam-ples investigate single factors and lead to reliable and well-founded results. However, they are often far away from implementation into agricultural practise. Applied research requires an interplay of on farm research and controlled experiments. A series of ethological research work at research institute of organic agriculture in Switzerland should show how this interplay may take place.

A NOVEL GREEN BIOREFINERY CONCEPT: Protein refining by lactic acid fermentation and biogas production from green biomass
Provedor de dados: 21
Autores: Fernandez, Maria Santamaria.
The extraction of proteins from leaves, integrated in a green biorefinery, may represent an attractive solution to the increasing demand for protein-rich animal feeds while decreasing the dependency on soybean imports. Thereby such green biorefineries could contribute to the development of more self-sufficient and sustainable agricultural systems in Europe. The framework of this PhD study is a green biorefinery concept for the production of protein concentrate, biogas and fertilizer from organic and locally grown green crops like alfalfa, clover or grass. After the screw pressing of the fresh crops, lactic acid fermentation of the green juice with Lactobacillus salivarius BC 1001 was assessed as the key method for the recovery of proteins. A leaf protein...

Effects of black soldier fly meal in poultry and fish diets on performance and product quality
Provedor de dados: 21
Autores: Leiber, Florian; Stadtlander, Timo; Wohlfahrt, Jens; Sandrock, Christoph; Maurer, Veronika.
Insect-based protein meals are in discussion as sustainable components in livestock and fish diets, with a potential to recycle wasted food materials and to replace partly feeds from arable land. Black Soldier Fly (BSF; Hermetia Illucens) is of particular interest in this context. Since insect production for animal feed appears as an additional trophic level in the food chain, it should either base on substrates, which are not directly edible for livestock and fish, or significantly improve feed efficiency or product quality to justify its application. Feed efficiency and product quality after replacing conventional protein sources by BSF meal were therefore tested in recent experiments with layers, broilers and trout. In a layer experiment, respectively...

From soy to egg: Solidarity in the poultry sector. Taking the next step towards social soy production
Provedor de dados: 21
Autores: Klinkert, Heleen; van Bree, Miriam.
A Dutch feed manufacturer and a soy trader felt that soy imports from overseas can only be justified, if in addition to the organic standards, also social standards are met. Their idea was well received by other stakeholders in the egg production chain and resulted in a Memorandum of Understanding that states that 100% of the soy used in organic poultry feed should meet social criteria by the end of 2015.

Muligheter for utfasing av konvensjonelle dyr i økologisk fjørfeproduksjon ved fjerning av unntaksbestemmelsen
Provedor de dados: 21
Autores: Johanssen, Juni Rosann E.
NORSØK fikk i oppdrag fra Regelverksutvalget for økologisk landbruk å skaffe en første oversikt over hvilke konsekvenser og muligheter et krav om utfasing av unntaket for bruk av konvensjonelle dyr vil få for de økologiske produsentene, med hovedvekt på fjørfe. I Norge er det liten økologisk fjørfeproduksjon, men fjørfe er det husdyret som har størst forskjell i dyrevelferd når man sammenligner økologisk og konvensjonell produksjon. NORSØK har intervjuet produsenter, og sendt ut spørreundersøkelser til andre aktører. Hybridene som brukes i økologisk fjørfeproduksjon i dag ser ut til å fungere bra, men det er kun en økologisk kyllingprodusent som har dyr av økologisk materiale fordi de har egne økologiske foreldredyr. For å få fjørfe som er av økologisk...

Due to the residual effect of antibiotics and the need to eradicate its usage in poultry industry. A 98-days experiment was carried out to determine the efficacy of aqueous extract of fruits of Lagenaria breviflora Robert on faecal samples of birds of the pullet birds. Ninety (90) two-weeks old pullet birds were divided into two treatments (100 and 150g of Lagenaria breviflora per litre of water) and further subdivided into three replicates of 15 birds each. Data collected on faecal analysis (at weeks 8 and 16) were subjected to independent sample T-test. The analyzed result revealed a significant (p&lt;0.01) decrease in the oocyst per gram, egg worm count and and Total bacteria egg count at weeks 8 and 16 respectively.

Autores: Höhne, Anja; Bussemas, Ralf; Baldinger, Lisa.
Die Sicherung einer nachhaltigen und einheimischen Eiweißversorgung in der Monogastrierfütterung des Ökologischen Landbaus ist insbesondere im Hinblick auf eine Ausweitung der Produktion von großer Bedeutung. Körnerleguminosen dienen als Eiweißquelle in der Geflügelfütterung, und spielen als Stickstofffixierer eine wichtige Rolle in den Fruchtfolgen im Ökologischen Landbau. Da Saatwicken im Vergleich zu anderen Leguminosen geringe Standortansprüche aufweisen, ist eine Ausweitung ihrer Anbaufläche aus pflanzenbaulicher Sicht wünschenswert. Mit einem Rohprotein(XP)gehalt von um die 283 (206-393) g kg-1 T sind Saatwicken-körner zudem sehr eiweißreich, was sie für die Monogastrierfütterung attraktiv macht (Huang et al. 2017).

Improved Contribution of local feed to support 100% Organic feed supply to Pigs and Poultry
Provedor de dados: 21
Due to the request for using entirely organically produced feed for livestock by 31st December 2017 there is a need to explore and evaluate the practical possibilities in doing that from a production and animal welfare point of view. Thus, this work was initiated to suggest economical viable feeding strategies based on 100% organic feed across Europe, which will supply poultry and pigs the required level of nutrients in different phases of production and support high animal health and welfare.   Through co-operation between 11 partners, a range of feeding experiments were carried out with pigs (sows, piglets and finishers) and poultry (layers and broilers) focused on concentrate feedstuffs, roughage, and foraging from the range. In addition, three...

Autores: Bellof, Prof. Dr. Gerhard; Schmidt, Prof. Dr. Eggert.
The purpose of the present study was to test an organic feed for chicken production. Different feed mixtures with reduced dietary energy level (&lt; 12 MJ AME/kg) and reduced content of essential amino acids were investigated. In case of reduction a constant ratio of amino acids to energy was considered. Under the future European law for organic products all raw materials used for the feed were of organic origin.  The feed consumption of the different feeding groups ran conversely proportional to the diets energy level. The obtained fattening performance and carcass yield reached a high level under the circumstances of organic production.

Demonstration-scale protein recovery by lactic acid fermentation from grass clover – a single case  of the production of protein concentrate and press cake silage for animal feeding trials
Provedor de dados: 21
Autores: Santamaria-Fernandez, Maria; Ambye-Jensen, Morten; Damborg, Vinni K.; Lübeck, Mette.
There is an increasing interest in green biorefineries for the utilization of green biomass to provide a variety of valuable products. Proteins can be extracted from green biomasses such as alfalfa, clover, or grass and separated into protein-rich concentrates suitable for feeding to monogastric animals. Press cake suitable for feeding ruminant animals is also produced. Full implementation of such a green biorefinery requires knowledge and experience of production at demonstration scale. Moreover, product evaluation in animal-feeding trials requires a large amount of product. There has been collaboration in Denmark between several partners from industry and academia to assess the practicality and scalability of a green biorefining plant producing protein...

Workshop and desk study to appraise technical difficulties associated with organic pullet rearing
Provedor de dados: 21
Autores: Gordon, S.
Background  To date, Regulation (EC) 1804/1999 and UKROFS Standards allow conventionally reared pullets up to 18 weeks of age to be brought into systems of organic egg production.  Pullets must be reared according to the rules laid down in Regulation (EC) 1804/1999 and according to UKROFS Standards for at least six weeks, before the eggs may be sold as organic eggs.  The derogation for pullet rearing has been agreed for a transitional period expiring on 31 December 2003.  If pullets are to be reared from day old in an organic system in accordance with Regulation (EC) 1804/1999 and UKROFS Standards this may potentially create a number of technical problems, which may disadvantage UK producers considering organic egg production.  A series of workshops and a...

Breeding strategies in poultry for genetic adaptation to the organic environment
Provedor de dados: 21
Autores: Sørensen, Poul.
Regarding access to breeding material for laying hens to organic egg production the following can be concluded:  The breeding material available is genetically adapted to the cage systems. This cage adapted material has a shortcoming regarding behaviour in larger flocks that manifest in: too high tendency to feather pecking and cannibalism, and, independent of flock size, also to many mislaid eggs. Experiments has shown that feather pecking, cannibalism and nesting behaviour can be improved by selection. A search for alternative breeds/hybrids has not yet given the ideal "Organic hen". There seem to be a possibility for adaptation of laying bird to diets with lower crude protein that makes a production possible based on "home grown" crops even in Northern...

Zoonotic Risks of Rodents in Livestock Production
Provedor de dados: 21
Autores: Meerburg, Dr BG.
Besides economic losses through spoilage of feed or structural damage, rodent presence on  livestock farms can have serious consequences for public and animal health. Direct contact  between humans and rodents can be a way of pathogen transmission, but rodents can also  transfer (zoonotic) pathogens via livestock to consumers of livestock products. As prevention of food safety hazards is a priority throughout the food chain, the main aim of the work presented in this thesis was to obtain a better understanding of the risk of on-farm rodent presence in the Netherlands.

Djurmaterialets betydelse vid äggproduktion under ekologiska betingelser
Provedor de dados: 21
Sedan 1 augusti 2000 är det inte längre tillåtet att tillsätta syntetiskt metionin till ekologiskt värphönsfoder, vilket komplicerar sammansättningen av ett fullvärdigt foder. För att metioninrestriktionen inte ska påverka djurens välbefinnande negativt så finns det, som vi ser det, två lösningar. Antingen kan mängden utfodrad metionin ökas genom att öka proteininnehållet i fodret, vilket leder till en icke önskvärd överutfodring av protein, eller så kan man med avelsarbete genetiskt anpassa hönorna till ett foder med lägre metionininnehåll.

One of the main problems in free range husbandry of laying hens is the uneven use of the hen run. This leads to an overuse of pasture near the hen house. In a series of behavioural experiments we tried to determine management and structuring factors which may result in more hens in the run and a more even distribution of the animals.

Mussel meal in poultry diets - with focus on organic production
Provedor de dados: 21
Autores: Jönsson, Lotta.
The first limiting nutrients for poultry are the sulphur containing amino acids, particularly methionine. To fulfil the recommended requirement, conventional diets are supplemented with synthetic methionine. Since this is not allowed in organic production it becomes important to have access to alternative high quality protein feed ingredients. The aim of this thesis was to investigate whether blue mussels (Mytilis edulis) could be used as a protein source in diets for organic poultry and determine whether the amount of fish meal commonly used today in organic diets could be replaced with mussel meal. Four experiments during both short time periods and during whole production cycles were conducted to evaluate production performance, egg quality and animal...

Adding more value to added-value. An exploration of consumers’ perceptions and attitudes towards improved animal welfare standards in organic meat production processes
Provedor de dados: 21
Autores: Marian, Livia; Thøgersen, John.
The expansion of the organic food market and the growing competition are factors that fuel the differentiation of organic food products. Differentiation may be achieved by developing “organic-plus” products that integrate other value-adding characteristics beyond the organic quality. In this context, the aim of this study was to explore whether consumers would notice and value further improvements in the animal welfare standards than those imposed by organic regulation. The results of three focus groups designed as a concept test reveal positive attitudes towards the proposed production process from both regular and occasional organic buyers. The results further indicate that the proposed “organic-plus” products would probably be valued by a niche of...

Effect of Clover grass protein concentrate on performance, digestibility and egg quality of laying hens fed 100% organic diet
Provedor de dados: 21
Autores: Khanal, Tanka; Steenfeldt, Sanna.
From the beginning of 2018, inclusion of non-organic protein sources are not allowed in the diet of 100% organic poultry in Europe. In this situation, a major nutritional challenge is to make sustainable supply of organic protein and amino acid in competitive price. This necessity triggers to search alternative protein sources for sustainable organic egg production. Clover grass protein concentrate (CPC) is dried protein concentrate prepared by pulping clover grass mixture mainly containing Red clover to obtain green juice followed by fermentation, centrifugation and drying. The crude protein, lysine and methionine content in CPC were determined to be 355.6, 20.3 and 6.3 g/kg dry matter respectively. This research was carried out to study the effect of...

Analyse des Bio-Geflügelmarktes
Provedor de dados: 21
Autores: Schaack, Diana; Quaing, Henriette; Nusch, Tanja; Rampold, Christine; Beck, Margit M.
Der Bio-Geflügelmarkt in Deutschland ist zwar noch eine Nische, hat aber großes Wachstumspotenzial. Im BÖLN-Projekt „Analyse des Bio-Geflügelmarktes“ wurden Schlachtereien, Verarbeiter, Produzenten und Berater nach Hemmnissen und Chancen zur Weiterentwicklung befragt. Auf Produzentenseite gibt es vor allem Unsicherheiten bei der Genehmigung von Stallneu- und Umbauten, außerdem verfügen umstellungswillige Betriebe nicht immer über genügend Ackerfläche für die Fütterung des Geflügels. Bei Puten wird noch an langsam wachsenden, angepassten Zuchtlinien gearbeitet.  Chancen für den Ausbau des Bio-Geflügelmarktes bestehen im direkten Kundenkontakt, aber auch im Zusammenschluss der Produzenten zu Erzeugerorganisationen. Dies wird als eine Möglichkeit gesehen, um...

Die Verhaltensentwicklung von Legehennen in verbesserten Aufzuchtsystemen
Provedor de dados: 21
Autores: Keppler, C.; Lange, K.; Fölsch, D.W.
Artgemäße Legehennenhaltungssysteme zeichnen sich durch verschiedene Funktionbereiche, wie erhöhte Standorte und Sitzstangen, ausreichend Scharraum, Staubbademöglichkeit, Nester, Außenklimabereich und Auslauf aus. Die Ställe sind mit Tageslicht ausgeleuchtet und die Tiere werden nicht schnabelkupiert.     Konventionell in Dunkelställen, ohne erhöhte Sitzstangen aufgezogene Tiere zeigen Verhaltensänderungen und häufig Federpicken, das bis hin zum Kannibalismus führen kann. Eine Verringerung der Schäden wird durch eine Lichtreduktion des Kunstlichtes bis auf 10- 15 LUX erreicht. Junghennen aus konventioneller Aufzucht sind aus diesen Gründen nicht für die Einstallung in artgemäße Legehennenhaltungssysteme mit Tageslicht geeignet. Ziel dieser Untersuchung...

How to motivate laying hens to use the hen run?
Provedor de dados: 21
Autores: Zeltner, Esther; Hirt, Helen; Hauser, J.
In organic agriculture, hens are kept in free range systems. A free range is an enrichment for the hens and brings several advantages for them. Laying hens may show behavioural elements that are not possible in a poultry house. For instance, sunbathing behaviour is only shown in direct sunlight and not in artificial light (Huber, 1987). Hens spend 35.3-47.5% of their time with food searching (Fölsch and Vestergaard, 1981) and, in natural habitats, invertebrate food appears to be an importnat addition to the diet (Savory et al. 1978). Free range systems may also have an influence on animal health and product quality. Lopez-Bote et al. (1998) suggested that some constituents of grass might be of interest for the production of eggs rich in (n-3) fatty acids....

Vergleich von Hofmischungen, Alleinfuttermitteln und Eiweißergänzern für Monogastrier anhand ihrer in vitro praecaecalen Verdaulichkeit
Provedor de dados: 21
Autores: Blume, Leonie; Hoischen-Taubner, Susanne; Sundrum, Albert.
Im Projekt steht die Optimierung der einzelbetrieblichen Effizienz der Nutzung heimischer Proteinträger bei der Fütterung von Monogastriern im Fokus. Einschätzungen zur Passgenauigkeit heimischer Eiweißkomponenten im betrieblichen Kontext erfordern belastbare Informationen zum Futterwert, d.h. zu den Inhaltsstoffen und der Verdaulichkeit. Im Vorhaben wurden 147 Futterproben von 56 ökologisch wirtschaftenden Betrieben hinsichtlich der Nährstoffgehalte sowie der in vitro praecaecalen Verdaulichkeit analysiert. Insbesondere die Verdaulichkeit der Eiweißergänzer war sehr heterogen. Durch Informationen zur Verdaulichkeit der Futtermittel können verschiedene Optionen im Einsatz von Eiweißfuttermitteln besser beurteilt werden.

Analyse des Influenzastatus von Hausgeflügel in Freilandhaltung unter besonderer Berücksichtigung der Infektionsgefährdung durch Wildvögel
Provedor de dados: 21
Autores: Werner, Ortrud; Globig, Anja; Starick, Elke.
Wilde Wasservögel sind das natürliche Reservoir von Influenzaviren. Auch in Deutschland wurden in den letzten Jahren insbesondere in durchziehenden Wildenten Influenzaviren verschiedener Subtypen nachgewiesen, einschließlich der potentiellen Erreger der Geflügelpest H5 und H7. Bei Geflügelhaltungen mit Freilandauslauf besteht wegen möglicher Wildvogelkontakte ein erhöhtes Infektionsrisiko für das Wirtschaftsgeflügel, das untersucht werden sollte.  In einer deutschlandweiten Stichprobe wurden insgesamt 486 Geflügelbetriebe mit Freilandauslauf auf das Vorkommen von aviären Influenzaviren getestet. Bei 2,9 % der 205 untersuchten Gänsebestände und bei 0,7 % der 143 Entenbestände wurde eine Influenzavirusinfektion nachgewiesen. Die 117 untersuchten...

The ranging ability of sasso chickens grown under various types of agroecosystems
Provedor de dados: 21
Autores: Escobin, Jr., Dr Rectorino; Bondoc, Dr. Orville; Lambio, Dr. Angel; Arboleda, Dr. Cecilio; Dagaas, Dr. Claire.
The ranging ability of Sasso chicken was estimated using the ranging score as an indicator.  The chickens were allowed to range in three agro-ecosystems namely, rice-based, rambutan orchard and grassland.  The ranging score was significantly higher in rambutan orchard with 52 m-hr followed by the ranging score in grassland with 48 m-hr.  The ranging score was lowest in rice-based agroecosystem.    The differences in the ranging score among agroecosystem can be attributed mainly to the presence of trees as shade, the soil type, and the predominant weed species in each agroecosystem.  It was found that the higher the ranging score, the more the chicken used their daytime for the ranging acts i.e. “kahig at tuka”.    As a result of ranging, there was a net...

An der Fachhochschule Weihenstephan wurde in zwei Versuchen nachgewiesen, dass eine Putenmast mit modernen Hybridherkünften auch nach Verordnung (EWG) 2092/91 erfolgreich durchgeführt werden kann. Futtermischungen mit deutlich abgesenkten Energiegehalten (ME) sowie erniedrigten Gehalten an essentiellen Aminosäuren (EAS) - bei konstantem Verhältnis von EAS:ME – führten dabei zu vergleichbaren Mastergebnissen, da Geflügel mit abnehmendem Gehalt an ME die freiwillige Futteraufnahme steigert, bis eine identische ME-Aufnahme erreicht ist.  Es wurden zwei Putenherkünfte (BUT (BIG 6); KELLY (BBB)) über 18 (Hennen) bzw. 22 Wochen (Hähne) gemästet. Im ersten Versuch wurden die Futtergruppen "High" (H) u.

Evaluation of Laying Hen Strains for biodynamic Farms
Provedor de dados: 21
Autores: Zeltner, Esther.
In biodynamic and organic agriculture mostly the same strains of laying hens as in conventional agriculture are used. These strains require feed with a high nutrition level to tap the full potential of their genetic. When this feed is not available it may lead to health problems and ethological interferences as well as to a deficiency of performance. In this study, four potential adequate strains are evaluated and compared with a commercial strain using health and ethological parameters as well as characteristics of performance under biodynamic conditions. After one laying period the laying performance of Amberlik, Hyline, Sperber and Sussex was high but only the plumage condition of Sussex was acceptable. Therefore this strain will be used for further...

Common vetch (Vicia sativa L.) seeds are rich in protein and have shown stable yields under organic cultivation, but contain considerable amounts of anti-nutritional factors (ANFs). Based on reports about reducing ANFs in faba beans (Vicia faba L.) by germination, a 50:50 mixture of  erminated common vetch seeds and wheat was offered to laying hens. Voluntary intake of the germinated grains was 20% of total feed intake, which was not affected by treatment. Despite germinated grains replacing part of the laying hen feed, egg production and body weight of the hens did not differ.

Der Arbeitszeitbedarf für Legehennen in Bodenhaltung unterscheidet sich kaum von dem in der Volierenhaltung: Gesamtarbeitszeitbedarf und Verteilung auf die einzelnen Arbeitsgänge sind annähernd gleich. Der größte Arbeitszeitbedarf liegt mit einem Anteil von 53 % bei der Produktgewinnung. Die Betriebsführung macht einen Anteil von 17% am Gesamtarbeitszeitbedarf aus. Bei beiden Arbeiten handelt es sich um tägliche, meist mit hohem manuellem Aufwand verbundene Tätigkeiten. Produktgewinnung, Betriebsführung, Fütterung und Auslaufbewirtschaftung summieren sich auf 92 % des Arbeitszeitbedarfs. Einfluss auf den Arbeitszeitbedarf haben vor allem die Bestandsgröße und der Anteil an manuellen Tätigkeiten.

Wie beeinflusst eine Legepause das Verhalten und den Tierzustand von Legehennen.
Provedor de dados: 21
Autores: Zeltner, Esther; Hirt, Helen.
Einleitung    Legehennen werden normalerweise im Jahresumtrieb gehalten. Um in grossen Gruppen eine verlängerte Nutzung zu ermöglichen, braucht es eine künstlich ausgelöste Legepause (Mauser). Dies ist einerseits eine Erholungsphase für den Legeapparat und andererseits erneuert sich das Gefieder. Üblicherweise erfolgt die Auslösung der Legepause durch massive Lichtreduktion und Futterrestriktion. Dies kann für die Tiere eine starke Belastung bedeuten. Daher ist zurzeit die Auslösung der Mauser im schweizerischen Biolandbau verboten. Eine längere Nutzungsdauer der Tiere wäre aus ethischer Sicht jedoch sinnvoll, da so auch die Zahl der zu tötenden männlichen Eintagesküken der Legelinien verringert werden könnte. In einem früheren Versuch in Kleingruppen...

Workshop and desk study to appraise technical difficulties associated with organic breeder flocks and organic hatching
Provedor de dados: 21
Autores: Gordon, S.
BACKGROUND    To date, Regulation (EC) 1804/1999 and UKROFS Standards allow conventionally produced day old chicks up to three days of age to be brought into systems of organic table chicken production.  Chicks must be reared according to the rules laid down in Regulation (EC) 1804/1999 and according to UKROFS Standards for at least 70 days before the birds may be sold as being organic.  The derogation for organic breeder flocks was agreed for a transitional period expiring on 31st December 2003.  An extension to the derogation is being discussed at EU level (Article 14 Committee) but, as an interim measure, a new end date has not yet been published in the Official Journal.

Silage von früh genutzter Luzerne (Medicago sativa) als Eiweiß- und Raufuttermittel in der ökologischen Broilermast
Provedor de dados: 21
Autores: Weltin, Jessica; Sundrum, Albert; Bellof, Gerhard.
In der Gruppe der kleinkörnigen Leguminosen weisen Luzerne und Weißklee die höchsten Protein- und Aminosäurengehalte (Lysin, Methionin) sowie die höchsten Erträge pro ha auf. Luzerne, die in einem sehr frühen Vegetationsstadium geworben wurde, kann einen Proteingehalt von 300 g/kg TS, einen Lysingehalt von 18 g/kg TS und einen Methioningehalt von 5g/kg TS erreichen. Ein solches Material kann verlustarm konserviert werden, wenn die Prinzipien des Silierens konsequent angewendet werden. Ein zusätzliches Extrudieren des angewelkten Materials verbessert den Siliererfolg nicht. Bezogen auf die täglich Gesamttrockenmasseaufnahme nehmen Broiler große Mengen Luzernesilage auf: 10-20 % in der Aufzuchtphase und 30 % in der Mastphase. Um den niedrigen ME-Gehalt der...

Refined forage legumes as local sources of protein feed for monogastrics and high quality fibre feed for ruminants in organic production
Provedor de dados: 21
Protein supplementation is a challenge in organic livestock production. Use of imported protein feeds on organically managed farms limits the recycling of nutrients. Fractionation of forage legumes, through novel harvesting and biorefining techniques, into protein- and fibre-rich feeds for monogastrics and ruminants, respectively, can increase farm self-sufficiency with feed. Economic, environmental and social sustainability needs to be taken into account when developing concepts for localised food systems.  Mathematical models will be developed for protein yields of lucerne and red clover. Leaf stripping and juice production will be studied in experiments located in different regions in Europe and Turkey and assessed for feed value in monogastrics and...

Darüber hinaus wurde ihre Mehrzahlungsbereitschaft für Öko-Geflügel erfasst. Daraus können Hemmnisse und Chancen zur Weiterentwicklung des Öko-Geflügelsektors abgeleitet werden.  Die zwei wichtigsten Hemmnisse für das weitere Wachstum sind die Produktverfügbarkeit und die hohen Preisaufschläge. Verbraucher...

Einsatz mobiler Hühnerställe in der Praxis   – ein Vergleich von zwei Systemen
Provedor de dados: 21
Autores: Trei, Gerriet; Hörning, Bernhard; Lampert, Dorothee; Jahn, Josefine.
Der Anteil der Auslaufhaltungssysteme für Legehennen nimmt zu. Allerdings sind mobile Haltungssysteme noch nicht weit verbreitet. In Deutschland werden vor allem Mobilställe zweier Hersteller eingesetzt. Ein Hersteller setzt Folientunnel auf Stahlträgerkufen ein (Typ 1), der andere Ställe auf Rädern (Typ 2).  Ziel der Untersuchung war eine aktuelle Befragung der Mobilstallbetreiber(Typ 1: 110 Betriebe, Typ 2: 134 Betriebe) durchzuführen. 61 Fragebögen von Legehennenhaltern und 12 Fragebögen von Masthühnerhaltern wurden ausgewertet.  Betriebe mit Typ 1 hielten mehr Hühner und versetzten die Ställe weniger häufig. Die Hühner hatten im Vergleich zu Typ 2 weniger Auslauffläche. Betriebe mit Typ 2 erzielten höhere Eierpreise.

Silicas for control of the poultry red mite Dermanyssus gallinae
Provedor de dados: 21
Autores: Maurer, Veronika; Perler, Erika.
Control of the poultry red mite Dermanyssus gallinae is a challenge for organic as well as conventional egg producers. In organic agriculture, control should be attempted by mechanically acting substances (e.g. oils or diatomaceous earth), before acaricides are applied. Diatomaceous earth (DE) without acaricides was at least as effective as DE supplemented with pyrethrum or essential oils and a liquid formulation of silica in vitro. In on farm experiments, DE was effective during a limited period only, whereas the liquid formulation had a very good residual effect over several weeks.

Performance and range use of organic broilers with access to different vegetation in outdoor areas
Provedor de dados: 21
Autores: Hellwing, A.L.F.; Petersen, J.S.; Steenfeldt, S.
Outdoor range areas are an important part of the organic broiler production, and the question is how to make this area as attractive for the broilers as possible. The aim of the study was to investigate the influence­ of vegetation in outdoor range areas on performance, crop and gizzard content and range use of organic broilers. The experiment was performed on an organic form in the summer of 2015 and 2016. The outdoor range was a grass field (F) or grass field combined with a plantation (GP). There were two replicates for each type of outdoor range. Eight hundred broilers were allocated to each rep I icete. Feed intake were registered daily. In 2015, 80 broilers from each replicate were weighed at 7, 14, 28, 42, 56, 70 and 84 days ofoge, and in 20 I 6 at...

Grass protein - a golden chance to improve organic farming
Provedor de dados: 21
Autores: Fog, Erik.
Green protein from clover-grass or alfalfa is considered a valuable protein source for poultry and pigs. By concentrating the protein fraction from grass clover crops grown locally in Denmark, and by using biorefining technology, one expects to obtain a vegetable protein and amino acid source that can optimize feed formulation of organic layer and pig diets, thereby increasing the sustainability of  organic egg  and pig meat production as well as increase feed efficiency. Optimisation of the biorefining method is a continuing process, and recent studies have shown that the protein and amino acid content increased from 2016 to 2018.  Target groups are organic farmers, advisors, industry and scientists.

Hahnenküken von Legehühnern sollen leben! Und was machen wir dann mit den Hähnen? Zahlungsbereitschaft für Hahnenfleischprodukte unter Berücksichtigung des Informations-Framings
Provedor de dados: 21
Autores: Schröter, Iris; Mergenthaler, Marcus.
Eine angemessene Zahlungsbereitschaft für Fleischerzeugnisse von Legehybrid- oder Zweinutzungshähnen ist ein wichtiger Aspekt, um diese innovativen Konzepte der Legehennenhaltung wirtschaftlich tragfähig zu machen. Die vorliegende Studie untersucht die Auswirkung von Informations-Framing auf die Zahlungsbereitschaft für Fleischprodukte dieser Hähne. Das multiple lineare Regressionsmodell zeigt, dass sich ein hedonistisches Framing signifikant positiv auf die Zahlungsbereitschaft der VerbraucherInnen auswirkt. Im Gegensatz dazu beeinflussen die Einstellungen der VerbraucherInnen zur Tötung der Eintagsküken die Zahlungsbereitschaft nicht.

Ermittlung des Futterwertes und der Verdaulichkeiten der Blattmassen von Luzerne und Perserklee
Provedor de dados: 21
Autores: Hoischen-Taubner, Susanne; Sundrum, Albert.
Angesichts der guten Verfügbarkeit von feinsamigen Leguminosen als heimische Proteinquelle in der Wiederkäuerernährung stellte sich die Frage, ob das Rohprotein auch für die Versorgung von Monogastriern genutzt werden kann, wenn statt der Ganzpflanze nur auf die Blattmasse zurückgegriffen wird. Es wurden verschiedene Faktoren untersucht, um das Ertragspotential und den Futterwert der Blattmasse vor allem im Hinblick auf die Verfügbarkeit von praecaecal verdauchlichen Aminosäuren einzuschätzen. Die umfangreichen Untersuchungen ergaben, dass durch die Trennung der Blatt- von der Stängelmasse die Konzentration der hochwertigen Futterkomponenten pro kg Trockenmasse sowie die Verdaulichkeit signifikant erhöht werden kann.

Autores: Steenfeldt, S.; Horsted, K.; Therkildsen, M.
Slagtekyllinger vokser hurtigt, hvilket er en egenskab opnået gennem mange års avl og foderoptimering. Dette resulterer ofte i benproblemer og et lavt aktivitetsniveau, hvilket øger risikoen for sår og svidninger på fødderne. Ved brug af nye kyllingetyper med langsommere vækst og ændret fodringsstrategi forventes bedre velfærd, kyllinge-kød med ny spisekvalitet og bedre udnyttelse af føde fra udearealet.

Autores: Padel, Susanne.
Annex IB of the EU Regulation on organic farming (2092/91) sets out that animals on organic farms should be fed with feed stuffs from organic farming systems. Only if organic feed is not available in sufficient quantity and quality, can a set percentage of those non-organic components be used that are listed in Annex II. The derogations for using conventional feed are due to expire in August 2005 and currently negotiations in Brussels are concerned with what rules will apply after August. Several Organisation of  the organic sector have already taken significant steps to reduce the reliance on conventional feed for ruminants. In Denmark, all organic cattle have to be fed 100% organic diets, and BIOLAND and DEMETER in Germany have also included this in...

Nutrition of monogastrics: A summary of research conducted under the German Federal Programme for Organic Agriculture and other forms of Sustainable Agriculture
Provedor de dados: 21
Autores: ANON, AN.
The thematic focus of monogastric nutrition runs very regularly through the entire federal programme. A strong focus was on the use of feed made from 100% organic origin (EC Eco-Regulation). In experiments in 2006 on the use of roughage in outdoor rearing pigs, for example, it was shown that Jerusalem artichoke can lead to significantly higher weight gains, compared to the control, while weight gain decreased significantly in some cases using other roughages. In another project in 2007, the various processing methods for soybean cake and feed produced therefrom were tested on broiler chickens, laying hens and pigs. The aim was to develop a suitable technology to inactivate the anti-nutritive components in soy and thus to increase the protein digestibility...

Organic production of eggs, broilers and turkey is regulated by international and national regulations and differs from conventional production. Breeds and hybrids selected for conventional production are also used in organic production. Many traits that are important for animal welfare are affected both by environment and genetics. This report gives an overview of the research about how animals with different genetics can be more or less suitable for alternative production systems. Moreover, the answers from a questionnaire among Norwegian poultry producers are reported. Possibilities for the development of animals more suitable for the goals and regulations in organic production are discussed.

Organic diets with low energy and amino acid contents were studied (Bellof, et al. 2005) with positive effects on growth and carcass performance of broilers. Alfalfa is moderately rich in protein, pigments and saponins and limited content of energy (AME). This event could benefit the design of low energy diets. Also alfalfa was able to produce healthy broiler meat (low fat and cholesterol) with a special flavour (Ponte et al., 2004). In the conventional production the results are controversial. A trial with 6 % of alfalfa diet found reduced performance of broilers (Tkácová et al., 2011), and a long raising study (56 d) found high and low carcass yield with 17 and 45 g/d of alfalfa intake respectively (Ponte et al., 2004).

Darüber hinaus gehende Anforderungen von Verbraucherseite an eine "ideale" Geflügelhaltung würden aber weitere wirtschaftliche Belastungen bringen. Dieses Dilemma kann nur schrittweise gelöst werden.Zum einen sollen die Fütterungs- und Haltungsbedingungen optimiert werden, um die Leistungen zu verbessern. Dies ist vor allem ein Umsetzungsproblem, entsprechende Vorschläge wurden gemacht. Fernen kann schrittweise versucht werden, sich dem Idealbild weiter anzunähern. Dies erfordert eine Einbeziehung aller Beteiligten, aber auch eine Verbraucheraufklärung zur...

Development of an agroforestry system for chicken production
Provedor de dados: 21
Autores: Philipps, Lois; Engel, Cindy; Wolfe, Martin.
This report was presented at the UK Organic Research 2002 Conference. Because conventional production of chickens has gone further than any other animal production system towards complete control of the animal’s brief lives, development of effective silvo-poultry systems seems particularly necessary for these essentially woodland birds. The objective is to develop a production system that closely matches the physiological and behavioural needs of the animals being reared. For the example of chickens, this means trying to mimic a woodland/forest-clearing environment. By providing a wide range of trees, shrubs and herbs, it should be possible to provide shelter, nutrition and medicinal benefits for the birds. At the same time, the system needs to fulfil...

Refining proteins from green crops for high quality feed products for monogastric animals and dairy cows
Provedor de dados: 21
Autores: Lübeck, Mette.
Green biorefinery concepts have the potential to become a suitable solution for production of organic protein-rich feeds from green crops. Different green crops are studied as possible feedstocks for the development of an organic biorefinery system. For production of experimental feed for different feed trials, a demo-scale set up was made for a continuous refining process that included harvesting and processing of 400 tons clover grass. The clover grass was processed into a protein concentrate, a fiber-rich press cake, and a residual stream of soluble nutrients. The protein-concentrate was used in experimental feed formulations for egg-laying hens, broilers and pigs. The fiber-rich press cake was ensiled without additives, and used as feed for dairy cows....

Legehennenhaltung: Auslaufnutzung – optimale Strukturierung auf Praxisbetrieben
Provedor de dados: 21
One of the main problems in free range husbandry of laying hens is the uneven use of the hen run. Several former experiments showed that a good and manifold structuring is necessary to achieve a better use of the hen run and better dispersion of the animals.    Methodology:  The results of these experiments were implemented on eight farms and the effect was successfully tested with control groups on the same farms.    Results, conclusion, state of the art:  Especially the middle part of the hen run was used more often. However the nearest part to the hen house will always be frequently used as the hens have to pass it to reach the distant parts of the hen run. Alternating use of the hen run near the hen house and good and manifold structuring in the...

How to fulfill EU requirements to feed organic laying hens 100% organic ingredients
Provedor de dados: 21
Autores: van Krimpen, M.M.; Leenstra, F.; Maurer, V.; Bestman, M.
From December 2017 onward, including non-organic protein sources in diets for organic poultry will no longer be allowed in the EU. Moreover, in the EU the use of synthetic amino acids in organic diets is prohibited. The main dietary challenge in European organic egg production is to fulfill the protein requirement, especially the methionine (Met) requirement of the hens. Currently available Met-rich ingredients are discussed. In the group of ingredients of plant origin, expelled sunflower seed has a relatively high digestible Met content and is also commonly available. Met content of plant ingredients can be increased by selection of high Met varieties and by specifically breeding on high Met content, e.g. by crossing different breeds. Plant processing...

Bedre øko-kyllinger med nye genotyper og fodringsstrategier
Provedor de dados: 21
Autores: Steenfeldt, Sanna.
Danske økologiske slagtekyllinger har stadig en lav markedsandel - mindre end én procent - selv om produktionen har udviklet sig positivt siden 2014. Skal afsætningen blive bedre i fremtiden, er der brug for både forbedringer i den eksisterende produktion og for helt nye, alsidige og bæredygtige produktionsystemer.   I forskningsprojektet Multichick arbejder vi derfor på at udvikle nye funkionelle produktionssystemer, hvor kyllingeproduktion bliver kombineret med produktion af træ og energiafgrøder. Dermed kan man både reducere udvaskning af kvælstof fra kyllingernes udearealer, udnytte arealet bedre og sikre bedre dyrevelfærd. Vi vil identificere både barrierer og muligheder i hele kæden fra jord til bord og komme med forslag til, hvordan den økologiske...

Possibilities and limitations of protein supply in organic poultry and pig production
Provedor de dados: 21
Autores: Sundrum, A.; Schneider, K.; Richter, U.
It is one of the general recommendations in animal nutrition that the diet should be formulated according to the specific requirements of animals at the various stages of their development. To which degree the farmer can adapt the nutrient supply to the specific requirements of the animals depends primarily on the production goal and on the availability of nutrient resources. This report gives a general introduction to the present situation for dietary protein supply to poultry and pig production in relation to the principles for organic agriculture and husbandry production. Furthermore it includes partly literature based on research from conventional animal production, as the requirements on the level of the animals are not different in both systems....

Ethological investigation on moulting laying hens in organic farming
Provedor de dados: 21
Autores: Zeltner, Esther; Hirt, Helen.
Introduction  Organic egg farmers mainly rely on the same hybrids, breeding techniques and production schemes as conventional egg producers. This includes annual replacement of the laying hens. However, from an ethical point of view a longer life for laying hens is desired, not only because the hens can be used for a longer period but also less male chicks would have to be killed at one day of age. Birds have to moult their plumage from time to time. During this time they hardly take in any food and stop laying. This laying interval presents a recuperation period for the egg producing organs of the hen. After moulting, egg production is again higher and the egg quality is improved. In large flocks of laying hens moulting has to be induced to prevent social...

PERFORMANCE AND BEHAVIOUR OF CHICKENS WITH DIFFERENT GROWING RATE REARED ACCORDING TO THE ORGANIC SYSTEM
Provedor de dados: 21
Autores: CASTELLINI, C; DAL BOSCO, A; MUGNAI, C; BERNARDINI, M.
The performance and the behaviour of three different chicken strains, reared according to the EEC-Regulation 1804/1999 organic system, were compared. The strains had very slow (Robusta maculata), slow (Kabir) and fast (Ross) growing rates, respectively. The trial was carried out on 200 chickens (male and female) per strain. Rearing lasted 81 days as  required by the EEC Regulations. At slaughter age, 20 birds per group were killed. Robusta maculata and Kabir chickens showed more intense walking activity and better foraging aptitude; their antioxidant capacity was also superior. Ross chickens had a good growth rate and feed conversion index, reaching an excellent body weight, but the mortality and the culling rate were high indicating that fast-growing...

Review: Towards the agroecological management of ruminants,  pigs and poultry through the development of sustainable breeding programmes: I-selection goals and criteria
Provedor de dados: 21
Autores: Phocas, F.; Belloc, Catherine; Bidanel, J.; Delaby, Luc; Dourmad, J. Y.; Dumont, B.; Ezanno, Pauline; Fortun-Lamothe, L.; Foucras, G.; Frappat, Brigitte; Gonzalez-Garcia, E.; Hazard, D.; Larzul, C.; Lubac, S.; Mignon-Grasteau, S.; Moreno, C. R.; Tixier-Boichard, M.; Brochard, M.
Agroecology uses natural processes and local resources rather than chemical inputs to ensure production while limiting the environmental footprint of livestock and crop production systems. Selecting to achieve a maximization of target production criteria has long proved detrimental to fitness traits. However, since the 1990s, developments in animal breeding have also focussed on animal robustness by balancing production and functional traits within overall breeding goals. We discuss here how an agroecological perspective should further shift breeding goals towards functional traits rather than production traits. Breeding for robustness aims to promote individual adaptive capacities by considering diverse selection criteria which include reproduction,...

Every year about 2.3 million laying hen chicks are produced in Switzerland. This means also 2.3 million male chicks from laying hen lines have to be killed, as they are neither appropriate for fattening nor for breeding.     From an ethical point of view this is a baseless discreation of life.    The implementation of the first organic brooder gave reason to analyse the situation in Switzerland.    Methodology:  A survey with the Swiss brooders, a literature research and an interrogation of experts were carried out.    Results, conclusion, state of the art:  Most of the chicks are killed by CO2.  The opinions vary on the ideal composition and concentration of gas mixtures. Newborns are especially resistance to anoxia and incomplete stunning can be...

Contribution of feeds from range in organic broiler production
Provedor de dados: 21
Autores: Steenfeldt, S.; Horsted, K.; Sørensen, P.
A study with organic broilers with access to a large range area with herbs was performed and the effect of three broiler genotype (JA757, T851, SU51) with different growth rates and different feeding strategies (HP vs LP) on the animals' feed intake, growth and welfare was investigated. The results so far indicate that feed intake from range and animal welfare is dependent on type of allocated feed and growth rate of the broiler genotype. Thus, gait scores and foot and plumage condition showed that the fastest growing broiler genotype had some problems when fed normal broiler feed, whereas this was not the case for the other genotypes. The fastest growing broilers also ate more pelleted broiler feed compared to the slower growing breeds, which in contrast...

Effect of artificial structuring on the use of laying hen runs in a free-range system
Provedor de dados: 21
Autores: Zeltner, Esther; Hirt, Helen.
1. This study examined whether a free range with roofed boxes with sand to structure the hen run had an effect on the numbers of hens going outside and on the distribution of the hens in the hen run.  2. On a poultry farm with 8 flocks of laying hens of roughly 500 birds per flock, each flock was observed with and without roofed boxes with sand.  3. There was no difference in the number of hens on free range with and without roofed boxes but there was an influence on the distribution.  4. In free range with structures there was a higher percentage of the hens outside in the furthest quarter where the structures were located.  5. We conclude that structures in the free range have an effect on the distribution of laying hens.

Possibilities and limitations of protein supply in organic poultry and pig production. Summary of Results from EEC 2092/91 (Organic) Revision
Provedor de dados: 21
Autores: Sundrum, Albert.
One of the main objectives of organic agriculture is to establish a largely closed nutrient cycle within the farm system. To limit the input of nutrients in quantity and quality is relevant both to plant and livestock production. If nutrient input is unavoidable to ensure an adequate supply for the farm animals, this should preferably originate from organic systems, while the input of conventional feed stuffs should be restricted to a minimum, and synthetic products are banned. Dealing with limited availability of feed and nutrient resources is therefore a main feature of organic livestock production.   The organic approach stands in contrast to the situation in conventional livestock production where the use of feeds and nutrients is restricted primarily...

Silage feeding for laying hens (OK-Net Ecofeed Practice Abstract)
Provedor de dados: 21
Autores: Steenfeldt, S.
High-quality silage can provide nutrients for the hen and encourage natural foraging behaviour, thus reducing the risk for feather pecking. Growing protein-rich silage helps increase self-sufficiency and improve the crop rotation of the organic poultry farms.    Practical recommendation  • Choose the silage type(s) that provides the best yield and quality, depending on soil type and weather con-ditions.  • The silage has to be finely chopped.  • Silage generally has to be preserved under proper conditions to optimize the fermentation process.  • Analyse the protein content of the silage and other nutrients if possible.  • Avoid silage with anti-nutritional factors.  • Investing in an automatic feeding system (robot) is recommended for larger flocks to...

„Weiße Braunleger“ – Sind diese neuen TMA-toleranten Legehennen-Hybriden für den Ökolandbau geeignet?
Provedor de dados: 21
Autores: Rahmann, Gerold; Holle, Romana.
Rape cake can be a good source of high protein for laying hens. Consumers in Ger-many prefer brown organic eggs and pay a higher price than for white eggs. Brown eggs are produced from hybrids which can have a genetic deficit for digesting Sinap-ine – a glucosinolate in rape cake - and produce “fish-eggs”. Rape cake has to be treated at a high temperature to destroy the glucosinolate, but this treatment is expen-sive. A new hybrid hen– Lohmann Silver TMAfrei – has no genetic deficit and still produces brown eggs. In a feeding experiment in 2004 and 2005, this hybrid showed comparable production and performance results to TETRA SL (typical organic hybrid) and LSL (white egg producer). The breed is suitable for use should feed stuffs with high glucosinolate...

Presence of Salmonella and Campylobacter spp. in Wild Small Mammals on Organic Farms
Provedor de dados: 21
Autores: Meerburg, B.G.; Jacobs-Reitsma, W.F.; Wagenaar, J.A.; Kijlstra, A.
The presence of Salmonella and Campylobacter spp. in rodents and insectivores (n = 282) was investigated on organic farms. Infections were encountered in house mice (8 of 83 Campylobacter positive and 1 of 83 Salmonella sp. strain Livingstone positive) and brown rats (1 of 8 Campylobacter positive) but not in other species. No shared Campylobacter genotypes were found between rodent and pig manure isolates. Effective on-farm rodent management is recommended.

Proteinforsyning i økologisk ægproduktion
Provedor de dados: 21
Autores: Steenfeldt, S.; Hammershøj, M.
I den økologiske fjerkræ- og svineproduktion er forsyning med tilstrækkeligt af de essentielle aminosyrer i foder et stigende problem, da foderet ifølge lovkravene skal indeholde en meget stor andel økologisk dyrkede råvarer. Der må ikke tilsættes syntetiske aminosyrer til økologisk foder, der fra 2012 skal være baseret på 100% økologiske råvarer. Selvom både den økologiske og den kommercielle husdyrproduktion er selvforsynende med nogle råvarer, er det stadig nødvendigt at importere en stor andel proteinråvarer for at tilgodese dyrenes behov for protein- og især aminosyrer. For lavt methionin-indhold i æglæggerfoder kan påvirke både ægproduktion og -kvalitet. En ubalance i foderets næringsstoffer kan være årsag til, at hønerne kommer i en mangelsituation,...

Laufhöfe für Freilandhennen: Es geht um die Glaubwürdigkeit
Provedor de dados: 21
Autores: Krebs, Adrian.
Wer Freilandeier kauft, erwartet, dass die Hühner das ganze Jahr Auslauf ins Freie haben. In der Vegetationspause ist das schwierig, denn die Grasnarbe hält der Belastung nicht stand. Zahlreiche Produzenten arbeiten deshalb mit ungedeckten Ausläufen. Diese sind aber umstritten, gewisse Halter betrachten diese als Krankheitsherde und zusätzlichen Kostenfaktor, zudem ist punkto Gewässerschutz vieles unklar. Ein FiBL-Projekt soll nun neue Erkenntnisse liefern.

Untersuchungen zu genetisch bedingten Unterschieden in der Parasitenresistenz von Legehennen – Testung unter den Bedingungen einer Stations- und Feldprüfung
Provedor de dados: 21
Autores: Gauly, Matthias; Kaufmann, Falko.
Die in der ökologischen Geflügelhaltung genutzten genetischen Herkünfte eignen sich aus verschiedenen Gründen in unterschiedlichen Maß für diese Verfahren. Die Bewertung der Eignung reduziert sich bisher im Wesentlichen auf Aspekte der Leistung (u.a. Eizahl, Eigewicht, Futterverwertung) sowie in gewissem Maße des Verhaltens (u.a. Kannibalismus). Aspekte der Tiergesundheit werden häufig auf Mortatiltätsraten reduziert, so dass u.a. subklinisch verlaufende Erkrankungen unberücksichtigt bleiben. In ökologischen Haltungsverfahren für Legehennen zählen die Parasitosen, insbesondere die Helminthosen, vor allem verursacht durch Ascaridia galli, Capillaria-Arten und Heterakis gallinarum, zu den bedeutendsten Erkrankungen (KAUFMANN und GAULY, 2009).

Insektlarver som proteinfôr til fisk og husdyr
Provedor de dados: 21
Autores: Wibe, Atle; Solemdal, Liv; Pommeresche, Reidun; Stangeland, Janne Kristin; Ween, Ola.
I dette prosjektet ble det gjennomført et dyrkningsforsøk av fluelarver for å undersøke muligheten for å bruke insektproteiner som fôr til fisk og husdyr. Larvene som ble produsert ble kjemisk analysert for å vurdere larvenes egnethet til fôr. Det ble også gjennomført en markedsundersøkelse blant fôrprodusenter og husdyrbrukere for å se på responsen for fôrprodukter laget av insektproteiner. Dyrkningsforsøkene viste at det er mulig å dyrke fluelarver, men at prosessen må optimaliseres for at det ikke skal bli for arbeidskrevende. Kvaliteten på vekstsubstratet for fluelarvene ser ut til å være avgjørende for å få en god larvevekst. Fluelarvene ser ut til å inneholde tilfredsstillende mengde næringsstoffer for at det kan brukes som fôr til fisk og husdyr....

Provedor de dados: 21
Autores: Breitsameter, Laura; Wedemeyer-Kremer, Barbara; Isselstein, Johannes.
In der Freilandhaltung von Legehennen ist die Bepflanzung der Auslauffläche sehr starken Belastungen ausgesetzt. Trotz etablierten Methoden des Auslaufmanagements hat dies häufig eine Verkahlung des Bodens zur Folge. Es besteht daher die Notwendigkeit, in Ergänzung zu den bekannten Praktiken der Auslaufpflege auch pflanzenbauliche Strategien zu entwickeln, welche zur Erhaltung einer intakten Vegetationsdecke beitragen.  In dem vorliegenden Projekt wurde die Eignung von vierzehn belastungstoleranten Grünlandgräsern und –kräutern zur Etablierung von belastbaren Grasnarben für die ökologische Geflügelhaltung untersucht. In einem Freilandexperiment wurde an Monokulturen und einer Mischsaat der untersuchten Arten die Wirkung von wiederholter Beweidung durch...

Mastleistung von Bruderhähnen bei Fütterung mit unterschiedlichen Proteinquellen
Provedor de dados: 21
Autores: Ammer, Stefanie; Quander, Nele; Posch, Julia; Maurer, Veronika; Leiber, Florian.
In drei Mastversuchen wurden die Wachstumsleistungen männlicher Legehybriden bei Fütterung mit unterschiedlichen Proteinquellen und -gehalten untersucht. Der Vergleich der Genotypen Lohmann Braun (LB) und Lohmann Selected Leghorn (LSL) mit dem Masthybriden Hubbard JA 757 (HUB) zeigte, dass die Bruderhähne erwartungsgemäss geringere Mastleistungen aufwiesen. Sowohl die Lebendgewichte und täglichen Zunahmen als auch die Schlachtgewichte wurden vom Genotyp beeinflusst.  Die LB-Hähne wiesen jedoch deutliche Vorteile in den Leistungen gegenüber den LSL-Tieren auf. Der partielle Ersatz von Soja durch Luzernegrünmehl in den Rationen, der mit einer Proteinreduktion einhergeht, führte vor allem bei HUB zu Leistungseinbussen.  Im Gegensatz dazu konnten für den...

Sensory profiles of breast meat from broilers reared in an organic niche production system and conventional standard broilers
Provedor de dados: 21
Autores: Horsted, K.; Allesen-Holm, B.H.; Hermansen, J.E.; Kongsted, A.G.
BACKGROUND: Breast meat from broilers produced in very different production systems may vary considerable in sensory profile, which may affect consumer interests. In this study the aim was to evaluate differences in the sensory profiles of breast meat from five broiler products: two conventional standard products (A and B) and three organic niche genotypes (I657, L40 and K8) reared in an apple orchard.    RESULTS: Thirteen out of 22 sensory attributes differed significantly between the products. The aroma attributes ‘chicken’, ‘bouillon’ and ‘fat’ scored highest and the ‘iron/liver’ aroma lowest for the niche products. The meat was more ‘tender’, ‘short’ and ‘crumbly’ and less ‘hard’ and ‘stringy’ in the standard products than in one or more of the niche...

Promoting good health and welfare in European organic laying hens
Provedor de dados: 21
Egg production in line with organic principles includes outdoor access, preferential use of preventative measures and alternative treatment methods, a 100% organic diet from 2012 onwards and consistent use of non beak-trimmed birds. This proposal focuses on the main challenges for organic laying hen farms regarding disease management, adverse animal welfare and negative impacts on the environment. Parasite infestation levels as well as prevalence of major health and welfare problems such as feather pecking, cannibalism, keel bone and foot lesions are affected by a combination of housing and management factors, e.g. with respect to feeding or hygiene, genotype or therapeutic treatments. The design and management of the range influence how well and evenly it...

Die bedarfsgerechte Versorgung von Monogastriern mit den essentiellen und limitierenden Aminosäuren ist von großer Bedeutung. Im Ökologischen Landbau wirft dies aufgrund von unbefriedigenden Aminosäureprofilen der zur Verfügung stehenden Getreide- und Körnerleguminosenarten sowie der fehlenden Verfügbarkeit alternativer Einzel- und Ergänzungsfuttermittel Probleme auf. Durch die Differenz zwischen Aminosäurebedarf und –versorgung entsteht die sog. Aminosäurelücke.

SUMMER chickens "on herbs"
Provedor de dados: 21
Autores: Steenfeldt, S.; Horsted, K.
In the organic RDD project ’SUMMER’, an experiment with organic broilers with access to a large range area with herbs has been performed. The effect of chicken genotypes with different growth rates and different feeding strategies on the animals’ feed intake, growth, welfare, health and meat quality was investigated.  The results so far indicate that it is necessary to use chicken genotypes with lower growth rates for a better welfare, and the focus should be on the individual genotype and its actual nutrient requirements and utilisation of feed from the range area.

The culling of day-old male layer chicks is a constant issue in the animal welfare discussion. The dual purpose chicken is an alternative. In this test cockerels from dual  purpose breeds were compared to fast and slow growing chicken. An additional fattening period of at least two weeks is necessary to achieve the final weight of 2.3  kg. Due to a decline in feed conversion approximately 20% additional feed energy is necessary to produce 1 kg lean meat. The laying performance reached an acceptable  number of 260 eggs per year. An insufficient egg weight is the reason for a higher amount of S-grade eggs. Again 20% additional feed energy per kg egg mass is necessary compared to specialized breeds.

In poultry, breeding is carried out by a very limited number of international operating breeding companies. For laying hens two companies dominate the market. Laying hens are in general 4-way crosses. Since 1960 the majority of commercial layers are bred and housed in cages. Non-cage housing started to appear again from 1980 onwards and increases slowly in importance, at first in Europe, but recently also in North America. It is questionable if birds bred to perform in cages are also suited for free range housing. In this project we examine the performance of current genotypes in free range systems (organic and conventional), and if and how an improved genotype for free range housing can be developed.

Increased foraging in organic layers
Provedor de dados: 21
Autores: Horsted, Klaus.
In this thesis it was hypothesised that that hens are capable of finding and utilising a considerable amount of feed items from a forage area, and this is dependent on the type of supplementary feed and forage vegetation offered. It was found that high-producing layer strains are able to consume considerable amounts of herbage and that forage together with other feed items from the forage area can provide laying hens with important nutrients. The type of supplementary (layer feed versus whole wheat and oyster shells) and the type of forage have an influence on the feed intake from the forage area. Thus, nutrient-restricted hens had a higher intake of herbage and a different preference for other feed items compared with hens, which had their nutrient...

MEAT QUALITY OF THREE CHICKEN GENOTYPES REARED ACCORDING TO THE ORGANIC SYSTEM
Provedor de dados: 21
Autores: CASTELLINI, Prof C; MUGNAI, Dr C; DAL BOSCO, Dr A.
The meat quality of three poultry genotypes with differing growth rates (fast-growing Ross; medium and slow growing Kabir and Robusta maculata, respectively) was compared. All the birds were reared according to the organic production system which requires a paddock with grass pasture (4 m2/bird) and a slaughter age greater than 81 d. The trial was carried out on 100 female chickens per strain. The meat quality was affected by the 20 different degree of maturity of the strains at slaughter age, which was 70% for Ross, 52 % for Kabir and 78% for Robusta maculata. Ross and Kabir were slaughtered at 81 d, whereas Robusta maculata, required 120 d to reach a commercial weight (&gt;2 kg). The meat of all the three genotypes showed good qualitative traits. The...

Lactic acid fermentation for refining proteins from green crops and obtaining a high quality feed product for monogastric animals
Provedor de dados: 21
Autores: Santamaria-Fernandez, Maria; Molinuevo-Salces, Beatriz; Kiel, Pauli; Steenfeldt, S.; Uellendahl, Hinrich; Lübeck, Mette.
Nowadays, the organic farming sector is growing at a fast pace in Europe while needs to face the lack of organic protein sources and in particular, feeding monogastric animals is becoming more and more urgent. Green biorefinery concepts might become the suitable solution for the sustainable production of organic protein-rich feeds from green crops. In this context, red clover, clover grass, alfalfa and oilseed radish were studied as possible feedstocks for the development of an organic biorefinery system in Northern Europe. For this purpose, the green crops were processed into a nitrogen-rich protein concentrate, a fiber-rich press cake, and a residual stream of soluble nutrients (brown juice). The process, which involved a novel protein refining technique...

Effects of paddock management on vegetation, nutrient accumulation, and intrnal parasites in laying hens
Provedor de dados: 21
Autores: Maurer, Veronika; Hertzberg, Hubertus; Heckendorn, Felix; Hördegen, Philipp; Koller, Martin.
Management of paddocks for free-range layers requires an effort from farmers to minimize the adverse effects of these systems on animal health (e.g., parasites)and environment (e.g., nutrient accumulation and leaching). In this study, we report results from 2 on-farm experiments conducted to investigate (1) the effects of rotational versus continuous use of the paddocks and(2) the effects of wood chips in the area close to the pop holes (openings to the paddock) with regard to turf quality, nutrient load in the soil, and parasite infections. Rotational use of the hen paddocks led to a lower proportion of bare soil close to the house, but not in more distant regions. Covering the area in front of the house with wood chips did not reduce bare areas. Nitrogen...

Biogas potential of green biomass after protein extraction in an organic biorefinery concept for feed, fuel and fertilizer production
Provedor de dados: 21
Autores: Santamaria-Fernandez, Maria; Molinuevo-Salces, Beatriz; Lübeck, Mette; Uellendahl, Hinrich.
The biogas potential of the residual fractions of four organically grown green crops after protein extraction was studied. The protein extraction method involved screw pressing of freshly harvested biomass to obtain a plant juice, followed by precipitation of the proteins. After protein extraction, 95% of organic matter was still present in the residual press cake and juice. Methane yields in the range of 219–375 and 429–539 ml-CH4 g-VS−1 were obtained for the mono-digestion of press cake and the residual juice, respectively, and up to 81% of the methane potential of the fresh crops was recovered in the two residual fractions when evaluated separately. Co-digestion of the press cake and the residual juice at the organic matter ratio at which those...

Proteins from organically grown green crops are promising poultry feed
Provedor de dados: 21
Autores: Lübeck, Mette; Molinuevo-Salces, Beatriz; Fog, Erik; Kiel, Pauli.
The overall purpose of the OrganoFinery project is to provide solutions to these problems by developing a green biorefinery where the organic crops are at the same time used for animal feed, fertilizer and energy production (methane). One of the project´s aims is to identify crops suitable for organic arable farms that have a general need for nitrogen. Sufficient nitrogen supply is essential for the production of protein; therefore, legumes or mixed cropping with legumes are particularly interesting for organic farmers, since these crops fix nitrogen.  In the bio-refining method, freshly harvested red clover and clover grass are mechanically separated into a green juice and a press cake using a screw press.  Organic protein feed is produced by lactic acid...

The Norwegian population of laying-hens comprises about 3.5 million, out of which about 240 000 are certified  organic. Breeding for high egg production and low body weight, combined with larger body weight in chicken  hampering the utilization of the same slaughter lines, has reduced the interest for utilizing laying-hens for food  purpose. Most hens are currently disposed of by gassing with CO2; either in the house or in a container being  brought to the farm. Dead hens are then transported to Hamar in South-East Norway, to become incinerated in  the only Norwegian plant for category 1-organic materials. Mobile slaughtering systems are relevant for poultry.  After slaughtering, the animals could be used for food, or processed by milling and enzymatic...

In a feeding trial broilers were fed with chopped, extruded and pelletized silage from young harvested alfalfa. The broilers consumed up to 30 % of silage of their total dry  matter intake. In comparison to the control group that was fed with a complete feed mixture, the meat of the silage groups showed a higher percentage of poly unsaturated fatty acids, a reduced cholesterol content and an intensive yellow colour. The sensory characteristics were not influenced. With regard to the human nutrition these changes in meat quality are desirable. Alfalfa silage can be used  deliberately to produce broiler meat with positive and healthy properties, and consequently as a marketing argument.

The relationship between perching behaviour, availability of perches and the incidence and severity of breast blisters in broilers was investigated together with a comparison between two slow-growing broiler strains.      2. Sixteen single strain groups (n=60) of Labresse and i657 broilers were subjected throughout the experiment to one of three perch availabilities: 15 cm per bird (Labresse and i657), 7.5 cm per bird (i657 only), and 0 cm per bird (i657 only) with four replicates per treatment. The birds were housed indoors from day-old, and at 43 days of age 52 birds from each group were moved to outdoor housing facilities with access to grass-covered outdoor areas until slaughter at 84 days of age.      3. The use of perches was monitored via video...

Autores: Trei, Gerriet; Burke, A.; Schumann, D.; Kalcher, L.; Hörning, Bernhard.
Aim of the study was to compare a new dual purpose hybrid strain (Lohmann dual, LD) with a layer strain (Lohmann Brown plus, LB) under organic conditions. 400 Laying hens were kept in 2 mobile houses (2 x 4 groups of 50 hens). Egg production  and egg weight were higher in LBP. LBP hens used the pasture more than LD. However, foraging was the main activity in both strains. LD hens showed less behavioral activity within the hen house. Plumage condition was better in LBP.

Juiste kip voor uitloop

Autores: van Niekerk, Thea; Reuvekamp, Berry; Bestman, Monique.
Livestock breeds (and breeding systems) developed for  intensive production systems often do not perform as  expected in organic and extensive systems. For these  alternative systems animals need good social and  ranging behaviour, which is in general not necessary in  intensive systems with greater confinement for the  animals. Although this is the case in all the livestock  species (e.g. dairy cows, pigs and sheep), in poultry, the  differences between organic/free range and  conventional systems are comparatively large.  This research focusses on adaptation of laying hens to the (new) free range systems

Hvor stor en rolle spiller siddepinde i forekomsten af brystblærer hos økologiske slagtekyllinger i Danmark?  Resultaterne fra undersøgelsen rapporteret her tyder på, at selvom adgang til siddepinde kan være associeret med en højere forekomst af alvorlige brystblærer, så har kyllingernes afstamning og køn en væsentlig højere indflydelse på forekomsten af brystblærer.

Kartlegging av helsestatus og bruk av antibiotika i økologisk kylling- og kalkunproduksjon
Provedor de dados: 21
Autores: Sørheim, Kristin.
Vi har undersøkt bruken av antibiotika i norske økologiske slaktekylling- og kalkunbesetninger. Bakgrunnen er at det har vært antatt at forbudet mot bruk av koksidiostatika i økologisk produksjon vil føre til mer sjukdom og økt bruk av antibiotika. Med forbehold om at det er svært få økologiske besetninger, gir undersøkelsen ikke indikasjoner på at kokidiostatikaforbudet fører til økt bruk av antibiotika i økologisk fjørfekjøttproduksjon.  Ingen av de fire økologiske besetningene har brukt noen form for antibiotika i kyllingproduksjonen i tidsrommet 2012-2015, som er tidsintervallet for undersøkelsen. Det har vært noen få tilfeller av antibiotikabehandling av økologisk kalkun. Vaksine som forebyggende tiltak er brukt rutinemessig i en av de fire...

Genetic improvement on feather pecking behaviour is effective
Provedor de dados: 21
Autores: Su, Dr. Guosheng; Kjaer, Dr. Jørgen B.; Sørensen, Prof. Poul.
Long term selection of laying hens for production in cage systems could have resulted in a poor adaptation to other rearing systems. One of the problems with the poor adaptation is feather pecking. The objective of the present study was to investigate genetic variation in feather pecking behaviour and genetic improvement on this trait by selection using an appropriate data-transformation and an animal model.   Conclusions  Large phenotypic variation for feather pecking behaviour.   No full-sib group effect can be found, indicating that maternal effect is negligible.  Moderate or low heritability.  Genetic improvement on feather pecking by selection is effective.

INTRODUCING TREES IN DAIRY AND POULTRY FARMS - Experiences dairy and poultry farmers' networks in The Netherlands
Provedor de dados: 21
Autores: Bestman, Monique; Eekeren, Nick van; Luske, Boki; Vonk, Mark; Anssems, Emiel; Boosten, Martijn; Bree, Miriam van.
In the Netherlands networks of goat, cow and poultry farmers started to grow trees in their fields and outdoor runs. This was done for different reasons: animal welfare (shelter); production of fodder, biomass, litter or fruits; spread of minerals from manure; increase biodiversity; keep away certain wild animals that carry diseases. In this abstract we present the project activities and the first experiences from the farmers. The so-called ‘silvopastoral’ systems (= combination of trees and animals) are applied traditionally already long times in Africa and Mediterranean countries. Now we apply them in modern, relatively high input animal husbandry systems.

Økologisk ægproduktion har bidt sig fast som en af Danmarks største økologiske fødevaresucceser målt som andel produceret og solgt økologisk. Økologisk ægproduktion er efter økologisk mælkeproduktion den vigtigste animalske økologiske produktion i Danmark. Det er imidlertid en produktionsform, der er følsom overfor kritik. I forbrugernes øjne er økologiske æg et alternativ til æg fra burægproduktion, som primært er kritiseret for manglende dyrevelfærd. Det er derfor vigtigt, at den økologiske ægproduktion kan dokumentere en tilfredsstillende dyrevelfærd. Dette aktualiseres af, at traditionel burægsproduktion er under udfasning i EU og at økologisk ægproduktion i fremtiden skal konkurrere mod nye alternative indhusningsformer med fokus på dyrevelfærd.

Provedor de dados: 21
Autores: CASTELLINI, prof C; PERELLA, dr F; MUGNAI, dr C; DAL BOSCO, dr A.
The welfare, production performance and some qualitative characteristics of eggs obtained under three different rearing systems (conventional, organic and organic-plus) were compared. Three homogeneous groups, each of 120 White Leghorn hens, fed the same diets, were assigned to different rearing systems and data were recorded for 1 year. The welfare indicators were the following: first impact, behavioural patterns, tonic immobility and plumage status. Productive performance was recorded (% deposition; egg weight) and some qualitative traits (Haugh index, yolk colour, yolk, albumen and egg shell weight) were evaluated. Well-being was greatly affected by rearing system. The best welfare status was observed in hens of the organic-plus group, whereas the worst...

Inventering av parasittrycket, särskilt spolmask, och dess samband med rastgårdens utformning och beläggning i ekologiska värphönsbesättningar
Provedor de dados: 21
Vi har planerat en fältstudie av hur hönsens nyttjande av sin rastgård i tid och rum påverkar graden av spolmaskinfektion i besättningen. Tjugo vidtalade lantbrukare med 800-10 000 höns vill utveckla utevistelsen för sina höns och ytan som de vistas på. Lantbrukarna tar prover för parasitanalys dels i gödselbädden, dels på det ställe i rastgården där hönsen vistas mest, samt på verandan där sådan finns. Fynden av ägg i proverna ställs mot information om stallets och rastgårdens utformning och användning. Information om detta inhämtas genom dokumentation gjord av de sökande och av lantbrukarna samt genom en intervju på varje gård.

Ökologische Legehennenhaltung: Strukturierung von Grünausläufen
Provedor de dados: 21
Autores: Zeltner, Esther; Hirt, Helen.
Die Stammform der Legehennen, das Bankivahuhn, lebt natürlicherweise in den Dschungelgebieten von Südostasien. Ihr natürlicher Lebensraum ist der Wald mit kleinen Lichtungen. In dieser Umgebung können sie rasch Schutz vor Gefahren finden. In unseren Breitengraden werden zwar immer mehr Hühner in Freilandsystemen gehalten, doch meist wird Ihnen eine offene und strukturlose Wiese als Auslauf angeboten. Daher sollte es nicht erstaunen, dass die Hühner den Grünauslauf nur teilweise nutzen und sich vor allem nicht sehr weit vom Stall entfernen. Ein Grossteil der angebotenen Wiese bleibt oft ungenutzt. Eine vermehrte Nutzung des Grünauslaufes, vor allem aber auch eine bessere Verteilung auf der Aussenfläche, ist daher erwünscht. In einem Versuch in Kleingruppen...

Nährstoffeinträge in der Freilandhaltung von Legehennen - Eignung von Kies im Nahbereich
Provedor de dados: 21
Autores: Deerberg, Frauke; Jalane, Verena; Deerberg, Friedhelm; Heß, Jürgen.
Der stallnahe Bereich wird in Grünausläufen von Legehennen besonders stark beansprucht. Durch den vollständigen Verlust der Grasnarbe sind hier häufig Erosion, Verschlämmung und Pfützenbildung zu beobachten. Zur Verringerung von Infektionsrisiken durch Erreger und der Anzahl von Schmutzeiern wird der Stallrandbereich, nach gängiger Empfehlung, oft mit Kies befestigt. Durch die starke Nutzung des Bereiches kommt es dort zu hohen Stickstoffeinträgen, die sich durch fortlaufenden Eintrag bei fehlendem Entzug akkumulieren und im Falle des NO3-N auswaschungsgefährdet sind. Ziel der Untersuchung war es daher zu testen, inwiefern sich Kies unter dem Aspekt des Nährstoffeintrages als Substrat im Nahbereich von Legehennenausläufen eignet. Geprüft wurden die...

Suitable conservation strategies for endangered domesticated breeds hinge on the knowledge of their special traits and benefits. We compared the performance of en-dangered geese and turkey breeds with common hybrid breeds, and focussed on meat quality as a potential marketing factor for a cost efficient on-farm conservation strategy. The animals were reared under identical feeding and housing conditions. In comparison with the endangered breeds, the hybrid breeds of both species were heavier and showed a lower feed conversion ratio. The meat of the endangered goose breed showed a higher drip loss, while the meat of the endangered turkey breed had less cooking loss, a higher shear force, and was preferred in a sensory test.

Optimering av ekologisk kycklingproduktion
Provedor de dados: 21
Ekologisk slaktkycklingproduktion i Sverige har en blygsam omfattning - omkring 0,1 % av den totala kycklingproduktionen. Skälet är svårigheten att uppfylla alla krav som omgärdar produktionsformen, vilket gör den problem- och riskfylld.                                                                Kraven är bl.a. att kycklingarna under sommarhalvåret ska ha tillgång till utevistelse. Inga kemiska preparat får användas i sjukdomsförebyggande syfte. Vidare är tillgången på godkända proteinfoderråvaror starkt begränsad och användning av syntetiska aminosyror är inte tillåten. Lägsta slaktålder för fjäderfä som inte är långsamväxande är 81 dagar.                                                                Problem som dessa regler innebär är främst:...

Legehennen bevorzugen langsame Mauser
Provedor de dados: 21
Autores: Zeltner, Esther.
Legehennen werden zunehmend nur noch ein Jahr gehalten. Was sich wirtschaftlich lohnt, ist technisch und ethisch nicht unproblematisch. Bei längerer Nutzungsdauer erfolgt nach einem Legejahr die Mauser, wo sich das Tier regeneriert. Diese heikle Phase, die auch gezielt ausgelöst werden kann, hat das FiBL genauer unter die Lupe genommen.     Legehennen werden heute normalerweise mit zirka 20 Alterswochen vom Aufzuchtstall in den Legehennenstall umgestallt. Diese Umstellung bedeutet für die Hühner Stress. Im Legehennenstall bleiben die Hühner ein Jahr lang. Anschliessend werden sie geschlachtet. Mit 68 Alterswochen ist somit das Leben der meisten Hennen zu Ende.     Die kurze Nutzungsdauer ist aus technischen und ethischen Überlegungen nicht unproblematisch....

Die Integration von zwei oder mehr Tierarten in pflanzenbauliche oder agro-silvo-pastorale Systeme hat mehrere Vorteile, unter anderem eine effizientere Weidenutzung und ein verbessertes Parasitenmanagement. Trotzdem tendieren ökologisch wirtschaftenden Gemischtbetriebe zur Spezialisierung bzw. zeigen nur begrenzte Verschränkung zwischen den einzelnen Komponenten. Diese Reduktion kann den praktischen Nutzen von Gemischtsystemen einschränken. Das Projekt zielt deshalb auf (i)...

Erfahrungen mit vollmobilen Hühnerställen in Deutschland
Provedor de dados: 21
Autores: Fuhrmann, Anne; Trei, Gerriet; Hörning, Bernhard.
Mobile Hühnerställe können eine interessante Alternative für den Ökolandbau sein um Probleme stationärer Freilandhaltung wie Zerstörung der Grasnarbe und Nährstoffanreicherung in Stallnähe zu vermindern. Erfahrungen von 17 Betrieben mit vollmobilen Hühnerställen wurden mit einem Fragebogen erhoben. Die Betriebe hatten insgesamt 26 Hühnermobile mit mehr als 5.000 Hennen im Einsatz. Die meisten Betriebe wirtschafteten ökologisch (88 %). In der Regel wurden Hühnermobile für ca. 200 Hennen eingesetzt. Die Leistungen waren gut (ca. 80 % Legeleistung und 5 % Mortalität). Die Betriebsleiter schätzten den Aufwand für Arbeitsvorgänge wie Versetzen der Mobilställe und Zäune. Bei Direktvermarktung wurden im Mittel 31 Cent je Ei realisiert.

Untersuchung der Eignung heimischer Grünlandarten für die Bepflanzung von Legehennen-Auslaufflächen
Provedor de dados: 21
Autores: Breitsameter, Laura; Wrage, Nicole; Isselstein, Johannes.
Die Erhaltung einer intakten Vegetationsdecke auf Auslaufflächen ist wichtig, um negative Umweltwirkungen der Geflügel-Freilandhaltung zu vermeiden. Im vorliegenden Projekt untersuchten wir im Rahmen einer Feldstudie die Eignung von vierzehn heimischen Grünlandarten für die Bepflanzung von Auslaufflächen. Durch die Beweidung mit Legehennen wurden bei den verschiedenen Arten signifikant (P &lt; 0.001) unterschiedliche Anteile des Aufwuchses von den Flächen entnommen. Die Besatzleistung war bei einigen untersuchten Arten ein signifikanter erklärender Faktor für ihre Wachstumsrate nach Ende der Beweidung. Wir schließen aus unseren Daten, dass Poa supina und Festuca arundinacea gut für die Begrünung von Geflügel-Auslaufflächen geeignet sein können, da weniger...

100 % organic ration works for organic table birds
Provedor de dados: 21
Autores: Woodward, Lawrence; O'Brien, Josie.
Poultry researcher Josie O’Brien and Lawrence Woodward present some results from a series of EFRC trials that are questioning the need for the conventional feed derogation in organic poultry production.  Currently the use of up to twenty percent of non-organic components is allowed in the feed ration of organically certified table birds.  Although this derogation is supposed to be removed in August 2005, there is mounting pressure to allow it to continue in some form. The derogation was introduced due to concerns that without it the bird’s nutritional needs could not be met by certified organic sources alone and therefore their health, welfare and growth would be compromised.  The primary concern relates to amino acid levels and in particular methionine....

Brüterei: Einfluss von Licht im Brutschrank auf das Verhalten von Junghennen
Provedor de dados: 21
Definition of the problem:  Imitated natural light conditions during the artificial incubation may influence pullets' behaviour in being adapted to the diurnal rhythm.   Methodology:  To study these effects, eggs were set in a commercial incubator either in the dark control or under full spectrum light tubes (Philips TL95, 36 watt). To imitate the light changes by a clucking hen, the eggs were exposed to light for twelve hours a day with a light-intensity of 20 lux. After six hours there was a step-up in light intensity to 1000 lux for 20 minutes. After the incubation period, at day 18 of incubation, all eggs were transferred to the hatching compartments. After hatching, the chickens were reared in paired groups under Swiss organic standards. Each group,...

Run management for organic layers
Provedor de dados: 21
Autores: Maurer, Veronika; Amsler, Zivile; Heckendorn, Felix; Koller, Martin; Perler, Erika; Zeltner, Esther.
Layer runs are often bare and loaded with nutrients and with infectious stages of helminths. Various management strategies are recommended in order to better distribute the hens in the run, thereby preventing local accumulation of droppings and related problems. However, little is known about the impact of those strategies.  A series of on farm experiments has been performed in order to test the effects of flock size and of artificial structures on the dispersal of the hens in the run. Further studies evaluated the effects of mowing and run size as well as rotational use of runs on turf quality, nutrient load in the soil and on the infection of the hens with internal parasites.  As a summary, introducing structures or applying a rotational management...

Zweinutzungsgeflügel
Provedor de dados: 21
Ethisch vertretbare Hühnerlinien, die wirtschaftlichen Kriterien genügen, sind heutzutage stark gesucht. Besonders in der Ökolandwirtschaft wächst das Bedürfnis nach robusten Hühnern, welche nicht infolge der Hochleistungszucht Schäden im Körperbau und Verhalten erleiden. Aus diesem Grund wurde in einer Pilotphase von 1997 bis 1998 untersucht, ob Zweinutzungshühner eine Alternative darstellen. Dabei könnten wie früher die Weibchen und die Männchen sinnvoll genutzt werden. Für die Untersuchung wurden zwei Linien geprüft, die auf dem Markt als Zweinutzungsgeflügel propagiert werden.

Autores: Velik, Margit; Baumung, Roswitha; Zaludik, Katrina; Niebuhr, Knut; Zollitsch, Werner.
Feedstuffs were analysed from 9 conventional and 12 organic farms which previously reported feather pecking in their laying hen flocks. Essential amino acid contents were significantly higher in conventional than in organic diets, while the latter matched suggested nutrient contents. Declared amino acid contents and results of analyses were in good agreement. Particle size of mash feedstuffs deviated from suggested values: percentages of coarse and medium particles were higher and lower, respectively, than suggested. Severity of feather pecking slightly correlated with dietary methionine content and with methionine:ME.

Fulfilling 100% organic poultry diets: Roughage and foraging from the range
Provedor de dados: 21
Autores: Crawley, Kenny.
The derogation from the EU Organic Regulatory Board to allow organic pig and poultry producers to include up to 5% non-organic feed within their rations was due to finish at the end of December 2014. This has now been extended to 31 December 2017 when it will become compulsory under EU Regulations (EC) no 889/2008 to provide all organic livestock with feed derived from organic origin. A further requirement of the regulation is that at least 20% of the feed should originate from the farm unit or if this is not possible from the same region. The organic regulations also dictate that roughage, fresh or dried fodder, or silage be added to the daily ration for poultry. In addition, poultry must be given access to pasture to complement their dietary requirements...

Towards sustainable management of  rodents in organic animal husbandry
Provedor de dados: 21
Autores: Meerburg, Bastiaan; Kijlstra, Aize.
From 26 to 28 May 2004 an international seminar was held in Wageningen, the Netherlands, about current knowledge and advice on rodent management on organic pig and poultry farms in Western Europe. This paper summarizes the discussions. Rodent management is necessary to protect the food production chain from health hazards to livestock and humans. Some organic farmers prefer biological rodent control, but since rodents can also transmit diseases this bears certain risks for the production of healthy livestock and safe food. Effective rodent management requires a thorough understanding of the biology of the pest species concerned. These can be divided into two groups: field rodents, such as voles,  and commensal rodents like house mice and rats. The...

Gebrauchskreuzungen - ökologische Nischenproduktion zur Erhaltung gefährdeter Haustierrassen?
Provedor de dados: 21
Autores: Vogt-Kaute, Werner; Damme, Dr. Klaus; Schreiter, Ruben.
In einem Testversuch wurden 3 Hähne der gefährdeten Hühnerrasse Mechelner mit 30 Lohmann braun Elternhennen gekreuzt. Es wurde die Leistung beider Geschlechter geprüft. Das Zielgewicht von knapp 2 kg bei den Hähnen wurde nach 84 Tagen erreicht bei einer Futterverwertung von 1:2,6. Das entspricht einer täglichen Zunahme von 23,4 Gramm. Die Hennen legten 248 Eier in 365 Produktionstagen und 268 Eier in 402 Produktionstagen pro Anfangshenne. Die Ergebnisse zeigen, dass die Kreuzung einer schweren Hühnerrasse mit einem Hybridelterntier eine akzeptable Fleisch- und Legeleistung erreichen kann. Jedoch sind die Ergebnisse aufgrund der geringen Anzahl an Hähner eher exemplarisch als für die gesamte Mechelner Rasse gültig.

Legehennenhaltung: Optimierung der Auslaufnutzung
Provedor de dados: 21
In der Schweiz wird etwa die Hälfte der Legehennen mit Grünauslauf gehalten. Meist ist jedoch nur ein kleiner Teil der Tiere im Auslauf und diese befinden sich hauptsächlich im stallnahen Bereich. Um den Boden und die Grasnarbe im stallnahen Bereich zu schonen, ist eine gute Verteilung der Hühner im Grünauslauf, also eine gleichmässige Nutzung aller Bereiche, wünschenswert. In diversen Untersuchungen konnte festgestellt werden, dass die Strukturierung des Grünauslaufes einen positiven Einfluss auf dessen Nutzung durch die Hühner hat. Ziel der aktuellen Untersuchung ist, die Resultate aus diesen Untersuchungen zusammenzufassen und auf Praxisbetrieben mit einer möglichst optimalen Strukturierung eine gute Auslaufnutzung zu erzielen

Organic livestock production in Uganda: potentials,  challenges and prospects
Provedor de dados: 21
Autores: Nalubwama Muwanga, Sylvia; Vaarst, Mette; Anthony, Mugisha.
Development in organic farming has been stim- ulated by farmers and consumers becoming interested in healthy food products and sustainable environment. Organ- ic agriculture is a holistic production management system which is based on the principles of health, ecology, care, and fairness. Organic development in Uganda has focused more on the crop sector than livestock sector and has primarily involved the private sector, like organic products export  companies  and  non-governmental organizations. Agriculture in Uganda and many African countries is predominantly traditional, less mechanized, and is usually associated with minimum use of chemical fertilizers, pesticides, and drugs. This low external input agriculture also referred to as “organic by default”...

Insect and legume-based protein sources to replace soybean cake in an organic broiler diet: Effects on growth performance and physical meat quality
Provedor de dados: 21
Autores: Leiber, Florian; Gelencsér, Tobias; Stamer, Andreas; Amsler, Zivile; Wohlfahrt, Jens; Früh, Barbara; Maurer, Veronika.
Protein sources other than soybean for the diets of poultry are needed for agricultural systems in temperate regions to help avoid some negative social and ecological impacts of large-scale soybean imports from overseas. The aim of the present study was to test the suitability of alternative protein sources in diets for slow-growing organic broiler  chicken. Four experimental broiler diets were tested against a commercial feed for organic broiler chicken fattening (control), containing 255 g kg−1 soybean cake. Each experimental diet was based on the control diet, but 130 g kg−1 of soybean cake was replaced with alternative feeds. The diet ‘HermAlf’ contained 78 g kg−1 Hermetia meal (dried larvae of the black soldier fly, Hermetia illucens) and 52 g kg−1...

Biokompatible Mauser bei Legehennen
Provedor de dados: 21
From an ethical point of view a longer life for laying hens is desired. Then, hens can be used for a longer period and less male chicks would have to be killed at the age of one day.    In large flocks of laying hens moulting has to be induced to prevent social instability in the flock.    Project aims:  A method was investigated in order to moult laying hens without too much stress for the hens.     Results, conclusion, state of the art:  The chosen method with daily access to a winter garden had no detectable negative effect on the behaviour of the hens. The moulting succeeded in improving egg quality and plumage condition.

Grünauslaufnutzung von Legehennen bei Wechselweide mit und ohne Tunnel
Provedor de dados: 21
Autores: Zeltner, Esther; Hirt, Helen.
Einleitung    In der Schweiz werden mehr als die Hälfte der Legehennen mit Grünauslauf gehalten. Doch die Ausläufe werden oft nicht wie gewünscht genutzt. Viele Tiere bleiben im Stall oder im Wintergarten und im stallnahen Bereich kommt es zu einer Übernutzung des Grünauslaufes. Um die Grasnarbe zu schonen hat sich ein Management mit Wechselweide bewährt. Da dies besonders bei mehreren nebeneinander liegenden Herden nicht einfach zu realisieren ist, entstehen oft enge Gänge. Im folgenden Versuch wurde untersucht, ob die Auslaufnutzung sich ändert, wenn die Hühner zuerst durch einen Tunnel auf die eigentliche Weide gelangen müssen und ob sie sich die Hühner anders verteilen als bei direktem Weidezugang.

Introduction    Regulation EC1804/1999 sets out the minimum standards for organic livestock production and UK organic poultry producers have to adhere to for organic poultry.  There are several aspects of Regulation EC1804/1999 which are technically and practicably challenging with regards to organic poultry production and most of these relate to feeding organic poultry.  The greatest problems relate to the need to feed mainly organic ingredients, there is a future requirement to feed 100% organic ingredients, and the banning of synthetic amino acids in feeds for organic poultry.    The issues raised by the introduction of Regulation EC1804/1999 are: 1) how do we match the supply of energy and nutrients to the bird’s needs for health, welfare and...

Legehennen im Biolandbau länger nutzen
Provedor de dados: 21
Autores: Zeltner, Esther; Hirt, Helen.
Legehennen werden heute normalerweise im Jahresumtrieb gehalten. Die Umstellung vom Aufzuchtstall in den Legehennenstall bedeutet für die Hühner eine Belastung, die umso grösser ist, je mehr sich das Aufzuchtsystem vom Legehennensystem unterscheidet. Mit 68 Alterswochen ist das Leben der meisten Hennen zu Ende. Die kurze Nutzungsdauer ist aus technischen und ethischen Überlegungen nicht unproblematisch. Die jährliche Eingewöhnungsphase der Hühner an den Stall ist für den Legehennenhalter immer mit dem Risiko verbunden, dass eine Herde in ihrer Anpassungsfähigkeit überfordert ist. Die Folge davon kann Federpicken oder sogar Kannibalismus sein.   Mit einer verlängerten Legedauer können die gut im Stall eingelebten Hennen länger genutzt werden und die Zahl...

Laying hen performance in different production systems; why do they differ and how to close the gap? Results of discussions with groups of farmers in The Netherlands, Switzerland and France, benchmarking and model calculations
Provedor de dados: 21
Autores: Leenstra, Ferry; Maurer, Veronika; Galea, Fabien; Bestman, Monique; Amsler-Kepalaite, Zivile; Visscher, Jeroen; Vermeij, Izak; van Krimpen, Marinus.
Free range and organic systems expose the laying hen more to unexpected events and adverse climatic conditions than barn and cage systems. In France, The Netherlands and Switzerland the requirements for a hen suitable to produce in free range and organic systems were discussed with farmers. The farmers preferred for these systems a more ‘robust’ hen, more specifically defined as a heavier hen with good eating capacity.  Benchmarking of flocks in a web-based management program in The Netherlands from layer flocks finished in 2008 – 2013 indicated that in earlier years indeed mortality among organic and to a lesser extent free range hens was higher than among barn or cage hens. Feed conversion (kg feed/kg eggs) is higher, but the gap is closing....

Management Systems for Organic Egg Production - Aiming to Improve Animal Health and Welfare
Provedor de dados: 21
Autores: Hegelund, Lene.
Animal health and welfare is an important part of the organic husbandry, both in terms of the organic principles and because of consumer interest. But problems in the organic egg production resulting in diseases, feather pecking and cannibalism, have led to the need of management tools in order to secure animal health and welfare.     The aim of this project is to develop management tools for the organic egg production, aimed to secure animal health and welfare in the flocks.    In the first part of the project a welfare assessment system for organic egg production was developed and tested on five farms, having a total of ten flocks. The ten flocks were monitored regularly for a number of production and welfare parameters in order to evaluate the practical...

Legehennen in einem mobilen Stallsystem - Flächenmanagement und resultierende Stickstoffgehalte im Auslauf -
Provedor de dados: 21
Autores: Fürmetz, A.; Keppler, C.; Knierim, U.; Deerberg, F.; Heß, J.
In the last years free range poultry was often criticised for its negative impacts on environment. As the animals do not use the run equally, a big part of the excreted nutrients are accumulated in the area close to the poultry house. This can lead to an increased rate of nutrient loss especially nitrogen by leaching.  Within this study the use of a mobile housing system for 1.000 layers on an organic farm in North Hessia with a mean of 700 mm precipitation per year and an average of 8,9°C (soil texture: loam in the first, silt loam in the second year) was observed for two years. A documentation and optimization of the management and regular investigations into the contents of mineral nitrogen in all parts of the outdoor run were carried out. The aim of...

Einfluss von Licht im Brutschrank auf das Verhalten von Junghennen
Provedor de dados: 21
Autores: Gnan, Renate; Hirt, Helen; Zeltner, Esther.
Imitated natural light conditions during the artificial incubation may influence pullets' behaviour in being adapted to the diurnal rhythm. To study these effects, eggs were set in a commercial incubator either in the dark control or under full spectrum light tubes (Philips TL95, 36 watt). To imitate the light changes by a clucking hen, the eggs were exposed to light for twelve hours a day with a light-intensity of 20 lux. After six hours there was a step-up in light intensity to 1000 lux for 20 minutes. After hatching, the chickens were reared in paired groups under BIO SUISSE organic standards. Each group, containing 1000 pullets, was observed at the age of 2, 4, 8 and 10 weeks in 5 trials. Several categories of behaviour, activity and the diurnal rhythm...

Organic diets with alfalfa silage for laying hens: Egg quality
Provedor de dados: 21
Autores: Carrasco, S.; Wüstholz, J.; Hahn, G.; Bellof, Gerhard.
Laying hens were fed with organic diets containing chopped, extruded or pelleted alfalfa silage and the quality of the eggs was evaluated. Four groups were conformed:  a control group (A) fed with a complete feed mixture (CFM) and three silage groups (B, C and D) fed with a supplementary feed mixture (SFM). The SFM was formulated  based on an assumed ingestion of 20 % silage and rapeseed oil was used as energy source. Before ensiling, the alfalfa was chopped (B) and additionally extruded (C).  One half of the extruded silage was pelleted together with the SFM to produce the pelletized silage (D). Eggs from hens fed with silage (B, C and D) contained 2.4 times  more n-3 fatty acids than A. The thermally treated silage (C and D) produced higher...

Roughage for organic laying hens
Provedor de dados: 21
Autores: Volmar, Jan.
Growing protein-rich roughage/silage can help increase self-sufficiency and improve the crop rotation on organic poultry farms. Different types of silage can be fed to layers daily and contribute to the poultry's nutrient requirements.  The roughage/silage is allocated several times a day with a mechanical suspension system. It also keeps the layers occupied and provides activity, minimising the risk of feather pecking.  The method is considered a new concept of producing protein rich roughage that can be used in feed formulation.  Target groups are organic farmers, but it is also valuable for advisors and scientists.

Rationsgestaltung und Eignung unterschiedlicher Herkünfte für die ökologische Hähnchenmast
Provedor de dados: 21
Die ausschließliche Versorgung von Masthähnchen mit ökologisch erzeugten Futtermitteln erschwert die Rationsgestaltung erheblich. Probleme bereitet hierbei eine adäquate Aminosäurezusammensetzung der Futtermischung bzw. das Verhältnis von Energie zu essentiellen Aminosäuren. Ferner schreibt die Verordnung (EWG) Nr. 2092/1991 für die ökologische Hühnermast die Verwendung langsam wachsender Herkünfte oder ein Mindestschlachtalter von 81 Tagen vor. Als langsam wachsende Herkunft werden in Deutschland überwiegend Tiere des Hybridzuchtunternehmens ISA-Hubbard eingesetzt, obwohl andere Genotypen auch geeignet erscheinen. In einer Stationsprüfung sind zwei Fütterungsstrategien an insgesamt vier langsam wachsenden Herkünften in zwei Durchgängen zu testen. Je...

Aim of the study was to carry out the outdoor use of laying hens and the feed supply from pasture in a mobile housing system in the summer time. Eight groups with 50 hens were used (Lohmann Brown Plus). The hens were kept in two mobile houses and according to the EU rules for organic agriculture. In a first subsequent experiment two area sizes (2,5 vs. 4,0 m²) and in a second subsequent experiment two frequencies of moving (7 vs. 14 days) were compared.   The outdoor use was recorded via direct observations of behaviour (scan and focal sampling). On average 64 % of hens were recorded in the run. Number of hens was decreasing with increasing distance from the hen houses (3 distance zones). Most frequent behaviour was foraging (45 % of hens in the run). Area...

Förekomst och riskanalys för spolmask (Ascaridia galli) i ekologiska och andra kommersiella värphönsflockar i Sverige
Provedor de dados: 21
I Sverige och flera andra EU-länder pågår omställnng av äggproduktionen från traditionella burar till mer djurvänliga inhysningsformer, till exempel ekologisk äggproduktion och frigående inhysning inomhus (golvproduktion). En nackdel med dessa inhysningssätt är att hönsens kontakt med träck ökar vilket kan leda till bland annat ökad risk för parasitinfektioner. En av dessa parasiter är spolmask (Ascaridia galli). Kunskapen om spolmask och dess effekter på svensk äggproduktion är i dagsläget begränsad. Den praktiska kunskapen om bekämpningsmetoder är dessutom otillräcklig. Eftersom spolmask kan orsaka både försämrad hälsa hos värphöns och därigenom ekonomiska förluster och leda till att spolmaskar ibland kan påträffas i konsumtionsägg så utgör studier av...

Provedor de dados: 21
Autores: Staps, Sjef.
Pluimveemest is een hoogwaardige meststof met veel stikstof, fosfaat en kali. De hoge fosfaatwaarden maken de afzet echter moeilijk. Akkerbouwers kunnen een beperkte  hoeveelheid fosfaat per hectare uit dierlijke mest per jaar op hun land brengen.  Pluimveemest bevat vaak evenveel stikstof als fosfaat. Door de fosfaatbeperking kan met deze mest dan vaak niet genoeg stikstof op het land kan worden gebracht.  Het project ‘Kippenmest &amp; Kringloop’ was vooral bedoeld om te onderzoeken hoe de stikstof-fosfaat verhouding kan worden aangepast, zodat deze mest beter bruikbaar is  voor de teelt van gewassen.

Was zieht die Hühner auf die Weide?
Provedor de dados: 21
Autores: Zeltner, Esther; Hirt, Helen.
Ein sonniger Sommertag auf einem Hof mit 500 Hühnern. Auf der Weide sind nur ein halbes Dutzend Hühner, die unter einem schattenspendenden Baum am Staubbaden sind. Der grösste Teil des Grünauslaufes ist leer. Warum nutzen die Hühner den zur Verfügung stehenden Auslauf nicht besser?    Mit dem oben beschriebenen Experiment konnte das FiBL zeigen, dass bereits ein einfacher Unterstand am Ende des Grünauslaufes die Hühner weiter hinaus lockt. Selbstverständlich ist dies keine ideal strukturierte Weide. Es zeigt nur, dass Hühner schutzbietende Strukturen aufsuchen oder sich wenigstens in deren Nähe häufiger aufhalten.    Um individuellen Präferenzen der Hühner gerecht zu werden, ist eine vielfältige Umgebung wichtig.

Quality of foraging material and effect on hens feed intake, egg production and -quality
Provedor de dados: 21
Autores: Steenfeldt, S.; Hammershøj, M.
The study shows that different kinds of foraging material can influence both egg-production and quality in organic egg production.  The composition of nutrients in the silages and carrots used in the present study was very different in content of protein, Met, starch and fibre. The particular batch of alfalfa silage used had a high content of protein and Met, which could contribute with essential amino acids. Diets based entirely on 100% organic feed ingredients could limit the supply of especially Met. Unfortunately, the alfalfa silage was also high in fibre content.  The results imply the importance of using foraging material of a high quality and further studies on the quality of other types of silages or vegetables are relevant in order to obtain an...

In vitro efficacies of oils, silicas and plant preparations against the poultry red mite Dermanyssus gallinae
Provedor de dados: 21
Autores: Maurer, Veronika; Perler, Erika; Heckendorn, Felix.
The aim of this study was to test the effectiveness of physically acting substances (oils and silicas) and plant preparations for the control of the poultry red mite Dermanyssus gallinae (De Geer 1778). Reproduction and survival of fed D. gallinae females were evaluated in vitro for a total of 168 h using the ‘‘area under the survival curve’’ (AUC) to compare survival of the mites between treatments. Four oils (two plant oils, one petroleum spray oil and diesel), one soap, three silicas (one synthetic amorphous silica, one diatomaceous earth (DE) and one DE with 2% pyrethrum extract) and seven plant preparations (derived from Chrysanthemum cineariaefolium, Allium sativum, Tanacetum vulgare, Yucca schidigera, Quillaja saponaria, Dryopteris filix-mas, and...

1. A total of 257 farmers with free ranging laying hens (organic and conventional) in Switzerland, France and The Netherlands with 273 flocks were interviewed to determine the relationships between the genotype of the hens, management conditions and performance.  2. Almost 20 different genotypes (brands) were present on the farms. In France, all birds were brown feathered hens laying brown eggs. In Switzerland and The Netherlands, there were brown, white (white feathered hens laying white eggs) and silver (white feathered hens laying brown eggs) hens.  In Switzerland, mixed flocks were also present.  3. The overall effect of system (organic vs. conventional free range) on egg production and mortality was significant, with higher mortality and lower egg...

Male chicken thigh meat quality from fast and slow growing breeds from an organic free-range system
Provedor de dados: 21
Autores: Karlsson, H.A.; Horsted, K.; Dufek, A.
Significant effects of Genotype and Age on several of the technological meat quality attributes measured were found. In general, the meat from fast growing birds (JA) was darker, more tender, had a higher water-binding but a higher cooking loss. Birds with a higher age at slaughter was more red, less tender and had a higher cooking loss. Regarding the protein concentration of the feed, no significant effects could be found on meat quality attributes, however a high protein concentration in the feed showed a tendency towards more tender meat.

Guidance notes to operators including recommendations in relation to nutrient supply
Provedor de dados: 21
Autores: Nicholas, P; Sundrum, A; Padel, S.
Restriction in the use of inputs and therefore limited availability of certain nutrient resources is a key characteristic of organic farming. Making best use of resources available on the farm implies that diet formulation needs to consider the availability of home–grown feed materials and the nutrient requirements of the livestock, as well as taking into account factors outside the farm gate, such as market conditions and consumer expectations.   It is therefore an on-going challenge for organic farmers to balance the different demands and the resources available.  In the move towards 100% organic diets organic pig and poultry producers are currently faced with a number of key issues in relation to the supply of energy and particularly protein that are...

Autores: Müller-Arnke, Ina; Rahmann, Gerold; Goeritz, Mareike; Koopmann, Regine; Schumacher, Ulrich; Plate, Hans.
This study was implemented to improve animal health of laying hens on organic farms. 20 farms were selected and animal health was evaluated. The farmers were inter-viewed about the housing system and management practices. Health and behavioural problems of the herd, as well as the incidence of endo- and ectoparasites were as-sessed. Housing facilities were evaluated and potential causes of health problems noted. Most of the farms have problems with damaged plumage and with the red mite (Dermanyssus gallinae). In most cases farmers know about these problems, but the reasons are difficult to find. This was the next step within the project (results not shown). Potential causes of problems were identified and farm specific animal health plans implemented to...

Das Zweinutzungshuhn – Hintergründe, Fakten und aktueller Stand der Dinge
Provedor de dados: 21
Autores: Urselmans, Stefanie; Damme, Klaus.
In den vergangenen Jahrzehnten hat die Zucht auf bestimmte Leistungsmerkmale wie Fleischansatz oder Legeleistung zwei Linien aus dem einstigen Haushuhn hervorgebracht, das Masthähnchen und die Legehenne. Während beim Masthähnchen beide Geschlechter gemästet werden, wird bei der Legehenne das männliche Tier, da es keinen ausreichenden Fleischansatz zeigt, am ersten Lebenstag getötet. Dies trifft zunehmend auf rechtliche und ethische Bedenken. Aus diesem Grund wird seit Jahren nach Alternativen für diese gängige Praxis gesucht. Lösungsansätze liegen im Bereich der in-ovo Geschlechtsbestimmung, einer verlängerten Legeperiode oder der Züchtung neuer Hybriden, welche eine gute Legeleistung und einen akzeptablen Fleischansatz zeigen.

Provedor de dados: 21
Autores: Fürmetz, A.; Keppler, C.; Knierim, U.; Deerberg, F.; Heß, J.
The use of the free-range area by laying hens housed in a mobile system and the resulting condition of the range were investigated. The free-range was used very intensively. On an average of nine complete observation days 35 % of the birds (23 – 44 % means per day) were outside the house. The maximum of animals in the free range was 77 %. 75 % (60 – 95 %) of the hens outside the house stayed in an area of 20 m around the house. This led to deteriorated conditions of the range in these areas. By moving the mobile house regularly (after 2 weeks in summer and 6 weeks in winter) a destruction of the vegetation could be avoided, while after not moving the house for three months in winter a complementary seeding became necessary.  We conclude that the use of...

One of the main problems in free range husbandry of laying hens is the uneven use of the hen run. This leads to an overuse of pasture near the hen house. In a series of behavioural experiments we tried to determine management and structuring factors which may result in more hens in the run and a more even distribution of the animals.

Introducing trees in Dutch dairy and poultry farms
Provedor de dados: 21
Autores: Bestman, M.; van Eekeren, N.
The potential of free range areas and grassland on organic farms for performing natural behaviour and offering natural feed is not fully utilized yet. Moreover, there are also chances to be picked up for enhancing biodiversity, carbon fixation and mineral cycling. For example, Dutch organic and free range poultry farms together have 2300 ha range area available. In dairy farms this area is much larger. Challenges on goat and cow farms are a natural enrichment of the ration of the animals  and making larger areas of the meadows attractive by providing natural shelter against bad weather. We try to ‘solve’ these problems by introducing forestry in animal production and designing silvopastoral systems. Silvopastoral systems, which are the combination of trees...

Einfluss von Bestandsgröße und Haltungsbedingungen auf Leistung, Mortalität und Gefiederzustand von Legehennen in Biobetrieben
Provedor de dados: 21
Autores: Hörning, Bernhard; Trei, Gerriet.
Aim of the study was to test possible influences on performance parameters in com-mercial layer farms. 106 flocks at 70 organic farms in Germany were investigated. Egg performance and mortality were collected from farm records. The integument of the hens was assessed with a scoring index (plumage condition and injuries).   Egg performance was higher at bigger farms. These farms showed often a better management (e.g. more health records or feed analyses). However, plumage was scored worse with increasing stock size. Bigger farms had higher densities in the hen house and at equipments like nests, feeders or drinkers. Therefore, more intensive housing conditions could have been the cause of plumage damages.

Effect of faecal soiling on skatole and androstenone occurence in organic entire male pigs
Provedor de dados: 21
Autores: Thomsen, Rikke; Edward, Sandra E.; Jensen, Bent Borg; Rousing, Tine; Sørensen, Jan Tind.
Production of entire male pigs could be a future strategy for organic pig production.  However, production of entire males leads to increased risk of carcasses with elevated boar taint levels. It is hypothesized that skatole levels in pig meat are affected by soiling with manure and that organic housing facilities can increase the risk of pigs being heavily soiled. Therefore the overall aim of this study was to investigate if increased pig and pen soiling increases skatole concentration in entire male pigs. In 5 herds, 1174 organic entire male pigs were reared in four batches across two seasons, summer and winter. Measurements of pig and pen soiling, as well as fat skatole and androstenone concentration and human sensory tests of fat odour, were performed....

The supply of protein and essential amino acids will undoubtedly be a great challenge for European poultry nutritionists when the transition to 100% organic feed ingredients for organic poultry production becomes reality. To avoid costly and energy consuming oversea transports connected to the import of soya beans, much research effort has focussed on the exploitation of alternative locally grown protein sources to increase the sustainability of organic production systems. Besides the cultivation of protein crops like legumes (peas, lupin, and faba been) and seeds (sunflower, rapeseed), new approaches including the feeding of protein concentrates from green biomass obtained by bio-refinement are discussed.

Health and Welfare in Dutch Organic Laying Hens
Provedor de dados: 21
Autores: Bestman, Monique; Wagenaar, Jan-Paul.
From 2007–2008, data on animal health and welfare and farm management during rearing and laying periods were collected from 49 flocks of organic laying hens in the Netherlands. Our aim was to investigate how organic egg farms performed in terms of animal health and welfare and which farm factors affected this performance. The flocks in our study were kept on farms with 34 to 25,000 hens (average 9,300 hens). Seventy-one percent of the flocks consisted of ‘silver hybrids’: white hens that lay brown eggs. Fifty-five percent of the flocks were kept in floor-based housing and 45% of the flocks in aviaries. No relation was found between the amount of time spent outdoors during the laying period and mortality at 60 weeks. Flocks that used their outdoor run more...

Fjäderfägödsel: innehåll av växtnäring och spårelement samt utveckling av provtagningsmetodik
Provedor de dados: 21
Resurshushållning av växtnäring innebär att stallgödsel ska utnyttjas så effektivt som möjligt i växtodlingen samtidigt som den negativa påverkan på omgivande miljö ska minimeras. Gödsel från fjäderfä produceras ofta på specialiserade enheter med liten egen odlingsareal. Fjäderfägödsel har därför blivit en handelsvara. För närvarande arbetar Jordbruksverket med att ta fram nya föreskrifter som gäller vid förmedling av gödsel. Ekonomiskt representerar växtnäringen i hönsgödsel ett stort värde. Ökad kunskap om fjäderfägödselns innehåll av växtnäringsämnen och spårelement gör det lättare att sätta rätt pris på produkten vid försäljning och att anpassa gödselgivan till grödans behov. Anpassning av givan till grödans behov och markförhållanden minimerar risken...

Autores: Böhm, Herwart.
In addition to the calculation of the metabolizable energy in feed for pigs and poultry, for cattle, and the Net Energy Lactation (NEL) for cows, the study also considers the contribution of other components, such as minerals, to the feed value. Data available to date, often from older sources, based on conventionally produced feed stuffs (DLG 1973). The data presented in this paper gives an overview of the mineral contents (P, K, Na, Ca and Mg) of the grain legumes pea, field bean, white, yellow and blue lupine and some summer cereals like oats, barley and wheat. Further, the effects of variety and year (weather conditions) are described. The well-defined material from the years 2002-2005 came from field experiments at the experimental farm of the...

Since 1960 the majority of commercial layers are housed in cages. Non-cage housing started to appear again from 1980 onwards and increases in importance. It is questionable if birds bred to perform in cages are also suited for free range housing. We examined the performance of current genotypes in free range systems (organic and conventional) by an inventory among laying hen farmers in Switzerland, The Netherlands and France (325 flocks on 275 farms) and organised workshops with farmers to discuss their ideas on breeding goals (‘the ideal hen’) for free range systems.

Verlängerte Nutzungsdauer von Legehennen im Biolandbau
Provedor de dados: 21
Autores: Zeltner, Esther.
Legehennen werden heute normalerweise im Jahresumtrieb gehalten. Die Umstellung vom Aufzuchtstall in den Legehennenstall bedeutet für die Hühner eine Belastung, die umso grösser ist, je mehr sich das Aufzuchtsystem vom Legehennensystem unterscheidet. Mit 68 Alterswochen ist das Leben der meisten Hennen zu Ende. Die kurze Nutzungsdauer ist aus technischen und ethischen Überlegungen nicht unproblematisch. Die jährliche Eingewöhnungsphase der Hühner an den Stall ist für den Legehennenhalter immer mit dem Risiko verbunden, dass eine Herde in ihrer Anpassungsfähigkeit überfordert ist. Die Folge davon kann Federpicken oder sogar Kannibalismus sein. Mit einer verlängerten Legedauer können die die gut im Stall eingelebten Hennen länger genutzt werden und die Zahl...

A study tour of organic poultry production in France - current &amp; future implementation of standards &amp; EU legislation
Provedor de dados: 21
Autores: Anon,.
Introduction    There have recently been major changes in the regulations governing the production of organic poultry products in the EU.  Member States have been required to set Standards for production that meet the minimum set in Regulation (EC) 1804/99 if products, including poultry, are to be sold as organic within the EU.  This has raised concerns over consistency of implementation in other Member States, and whether, directly or through derogation, this might lead to competitive advantage over the UK.    MAFF were aware that France had drafted derogations in accordance with Regulation (EC) 1804/99, and  intended to implement some aspects of the Regulation which  were claimed to be more stringent than the basic requirements.  The aim of this project...

Supermarket Loss Estimates for Fresh Fruit, Vegetables, Meat, Poultry, and Seafood and Their Use in the ERS Loss-Adjusted Food Availability Data
Provedor de dados: 31
Autores: Buzby,   Jean C.; Wells,   Hodan Farah; Axtman,   Bruce; Mickey,   Jana.
A certain amount of food in supermarkets is deemed unusable (“food loss”) because of moisture loss, spoilage, and other causes. This study analyzed updated food loss estimates for fresh fruit, vegetables, meat, poultry, and seafood obtained through a competitive grant with the Perishables Group, Inc. This independent consulting firm compared supplier shipment data with point-of-sale data from six large national and regional supermarket retailers to identify loss in 2005 and 2006. The new estimates, when incorporated into the ERS Loss-Adjusted Food Availability data, had little impact on aggregate per capita food loss estimates in 2006 because the new estimates were, on average, close to the previous loss assumptions. The new estimates increased annual per...

Industrialization and Contracting in U.S. Agriculture
Provedor de dados: 31
Autores: Ahearn,   Mary Clare; Korb,   Penelope J.; Banker,   David E.
This paper examines the industrialization process of U.S. agriculture by examining the trends in the number of farms, the concentration of production during the last decade, and the dynamics of farm survivability, entry, and exit underlying aggregate statistics.  We next examine vertical coordination as part of the industrialization process and highlight contracting in the poultry industry.  The analysis provides evidence that production is continuing to be concentrated on a smaller number of farms at a relatively rapid rate, in spite of the stability in the number of farms.  Although contracting clearly dominates the broiler industry, it is less prevalent in egg and turkey production, where other forms of vertical coordination are likely established.

Effects of China's Antidumping Tariffs on U.S-China Bilateral Poultry Trade
Provedor de dados: 31
Autores: Li,   Xiaofei; Gunter,   Lewell F.; Epperson,   James E.
In recent years, the United States has taken the lion’s share of the Chinese broiler meat import market, ranging from 53.0% to 84.9%. Under the threat of rising poultry imports from the United States Chinese producers asked for an investigation into chicken prices, accusing American poultry firms of dumping. The investigation led to antidumping duties on U.S. chicken imports as of February 13, 2010, ranging from 43.1% to 105.4%. This study is designed to evaluate U.S.-China poultry bilateral trade relations under the new tariff using an excess-supply-excess-demand model. The structural model is estimated using GMM with HAC (heteroskedasticity-autocorrelation) robust standard errors to obtain structural coefficients. The analysis focuses on chicken wings,...

Local Monopsony Power in the Market for Broilers - Evidence from a Farm Survey
Provedor de dados: 31
Autores: Key,   Nigel D.; MacDonald,   James M.
The exercise of monopsony power by broiler processing firms is plausible because production occurs within localized complexes, which limits the number of integrators with whom growers can contract.  In addition, growers face distinct hold-up risks as broiler production requires a substantial investment in specific assets and most production contracts do not involve long-term purchasing commitments by integrators. This paper provides an initial exploration of the links between the local concentration of broiler integrators and grower compensation under production contracts using data from the 2006 broiler version of USDA’s Agricultural Resource Management Survey.  Results of this preliminary study, which accounts for characteristics of the operation and...

Impact of the South Korea-U.S. Free Trade Agreement on the U.S. Livestock Sector
Provedor de dados: 31
Autores: Fabiosa,   Jacinto F.; Hayes,   Dermot J.; Dong,   Fengxia.
The recently signed Korea-U.S. Free Trade Agreement (KORUS FTA) grants the U.S. livestock industry with preferential access to South Korea's import market. This study evaluates the likely impacts of the KORUS FTA on the U.S. livestock sector.  Using the Food and Agricultural Policy Research Institute's modeling system, we find that livestock prices increase by 0.5% to 3.8% under the agreement. And together with an expansion by 381 to 883 million pounds in meat exports, the value of U.S. exports increase by close to U.S.$2 billion, or a 15.2% increase.  Because of differential baseline starting market shares and differential rates and staging specifications, the beef sector results are primarily driven by trade diversion impacts, while a combination of...

Efficiency and Distribution in Contract Farming: The Case of Indian Poultry Growers
Provedor de dados: 31
Autores: Ramaswami,   Bharat; Birthal,   Pratap Singh; Joshi,   P.K.
This paper is an empirical analysis of the gains from contract farming in the case of poultry production in the state of Andhra Pradesh in India. The paper finds that contract production is more efficient than noncontract production. The efficiency surplus is largely appropriated by the processor. Despite this, contract growers still gain appreciably from contracting in terms of lower risk and higher expected returns. Improved technology and production practices as well as the way in which the processor selects growers are what make these outcomes possible. In terms of observed and unobserved characteristics, contract growers have relatively poor prospects as independent growers. With contract production, these growers achieve incomes comparable to that of...

Autores: Ambarawati,   I Gusti Agung Ayu; Prasetyo,   Bugie Kurnianto; Patrick,   Ian.
This paper measures the cost of implementing biosecurity on broiler and layer farms in Bali. Farmer investment in biosecurity is analysed to determine if there is any difference in the implementation of biosecurity between broiler and layer farms. Data is taken from a survey of 60 layer and 60 broiler smallholder farmers in Bali in 2009. While secure boundary fencing and farm gate locks are more common on layer farms, broiler producers are more likely to have a footbaths at the shed door. In this analysis, biosecurity investments include the quality of fencing and gates, presence of locks on gates, management changes required to minimise staff and visitor movement onto and in the farm, costs of minimising vehicle entry, use of vaccination and disinfectant,...

Provedor de dados: 31
Autores: Perry,   Janet E.; Banker,   David E.; Green,   Robert C.
This study provides a comprehensive view of the organization, management, and financial performance of U.S. broiler farms. Using data from USDA's Agricultural Resource Management Study (ARMS, formerly known as the Farm Costs and Returns Survey), we examine farm size, financial structure, household income, management practices, and spousal participation in decision-making. We compare broiler operations with other farming enterprises and their earnings with that of the average U.S. household. Because most of the 7 billion broilers produced in the United States in 1995 were raised under contract, we also explore the use of contracts and the effects of contracting on the broiler sector.

Control of Newcastle Disease in Village Chickens
Provedor de dados: 31
Autores: Centre for International Economics.
Between 1983 and 1992, the Australian Centre for International Agricultural Research (ACIAR) invested A$3 million in research to find a vaccine that could provide protection from Newcastle disease in chickens and be applied in village environments in developing countries. A further $160 000 was invested in follow up projects which ended in 1996. Village chickens often provide the only source of protein to poor villagers living in remote areas and Newcastle disease frequently devastates unvaccinated village flocks. The ACIAR-sponsored research was highly successful in developing a heat resistant vaccine (HRV4) which could be readily used in the field by coating it onto chicken feed. The vaccine was commercialised by an Australian company which subsequently...

Effects of Country-of-Origin Labeling on Meat Producers and Consumers
Provedor de dados: 31
Autores: Lusk,   Jayson L.; Anderson,   John D.
Although several studies have estimated the costs of country-of-origin labeling (COOL), no previous study has documented how these costs will be distributed across the livestock sector or how producer and consumer welfare will be affected. This analysis presents an equilibrium displacement model of the farm, wholesale, and retail markets for beef, pork, and poultry that documents how producers and consumers will be affected by COOL. Findings reveal that as the costs of COOL are shifted from the producer to the processor and retailer, producers are made increasingly better off while consumers are made increasingly worse off. Further, an increase in aggregate consumer demand of 2% to 3% is likely sufficient to offset lost producer welfare due to COOL costs.

In this study we estimated the price elasticities among meats, vegetables, grains, and potatoes and the impact that different levels of income have on the demand for these commodities.  The 2005 Nielsen retail home scan data were used to construct a censored demand system of 14 equations.   Results revealed that the uncompensated cross-price elasticities for both low and high-incomes suggest both substitution and complement relationships, while the compensated price elasticities are dominated primarily by substitution relationships.  Our findings also revealed that expenditure elasticities among both low and high-income households differ for most commodities.

Understanding the impacts of the Uruguay Round (UR) Agreement on southern commodities serves as a starting point to assess the potential impacts of the next global trade negotiations in terms of hope (expanding export markets) and fear (new competition).  Key issues examined include whether or not the UR Agreement resulted in new markets or new competition for key southern commodities-cotton, poultry, tobacco, and rice.  For new markets, export data were analyzed to determine if exports increased since the passage of the UR Agreement in 1994.  Also, countries that are leading world importers of these southern commodities were identified and data analyzed to determine whether the U.S. is exporting to these top markets.  Alternatively, to assess whether the...

Census of agriculture data were used to estimate manure nutrient production and the capacity of cropland and pastureland to assimilate nutrients. Most farms (78 percent for nitrogen and 69 percent for phosphorus) have adequate land on which it is physically feasible to apply the manure produced onfarm at agronomic rates. (The costs of applying manure at these rates have not been assessed). Even so, manure that is produced on operations that cannot fully apply it to their own land at agronomic rates accounts for 60 percent of the Nation's manure nitrogen and 70 percent of the manure phosphorus. In these cases, most counties with farms that produce "excess" nutrients have adequate crop acres not associated with animal operations, but within the county, on...

This paper describes an interdisciplinary research project carried out on behalf of the Federal Ministry of Consumer Protection, Food and Agriculture. The project combines the knowledge of food experts with decision-orientated approaches from microeconomics and the social sciences. It examines what it is that makes food business operators (from the feed industry to the retail trade) break (or not break) rules. Through the analysis of both economic incentives and social context factors, the project aims at contributing to an adequate design of prevention measures. Four offence-prone regulations identified in the course of the ongoing project are exemplarily examined with regard to the present incentive situation.

The Economic Organization of U.S. Broiler Production
Provedor de dados: 31
Autores: MacDonald,   James M.
Broiler production in the United States is coordinated almost entirely through systems of production contracts, in which a grower’s compensation is based, in part, on how the grower’s performance compares with that of other growers. The industry is undergoing a gradual structural change as production shifts to larger broiler enterprises that provide larger shares of an operator’s household income. Larger enterprises require substantially larger investments in broiler housing, and new or retrofitted houses are also an important source of productivity growth in the industry.

The Costs of Biosecurity at the Farm Level: the Case of Finnish Broiler
Provedor de dados: 31
Autores: Siekkinen,   K.-M.; Heikkila,   Jaakko; Tammiranta,   N.; Rosengren,   H.
In the European Union, the animal health and food safety strategy includes managing biosecurity along the entire production chain. Farm-level biosecurity provides the foundation for this. However, the farm-level costs of preventive biosecurity have rarely been assessed. Yet many risk management practices are in place constantly regardless of whether there is a disease outbreak or not. We contribute towards filling this information gap by studying the costs incurred in preventive biosecurity by the Finnish poultry farms. In a preliminary analysis, we find that the cost of biosecurity is some 3.55 cents per bird for broiler producers and 75.7 cents per bird for hatching egg producers. The results indicate that work-time devoted to biosecurity represents some...

Curtailing Fertilizer Scarcity and Climate Change; an appraisal of Factors Affecting Organic Materials Use Option in Nigeria’s Agriculture
Provedor de dados: 31
Autores: Omotesho,   O.A.; Fakayode,   S.B.; Tariya,   Y.
Global trends nowadays towards long term sustainable crop production is hinged on either supplementing the use of chemical fertilizers with organic materials or a complete use of organic materials. This is more so since substituting chemical fertilizers with organic materials reduces the risks of exposure to ailments that arise on account of synthetic compounds and increases farmers’ gains via reduced soil erosion and carbon emissions and increased bio-diversity. In this vein, the current study investigated organic materials use in Nigeria’s agriculture. Specifically, the study examined availability and use of chemical fertilizer and organic materials substitutes and investigated factors affecting the use of organic materials in the Nigerian food sector....

Autores: Bjornlund,   Britta; Cochrane,   Nancy J.; Haley,   Mildred M.; Hoskin,   Roger; Liefert,   Olga; Paarlberg,   Philip L.
This report examines the restructuring of the livestock sectors in five countries: Russia, Ukraine, Poland, Hungary, and Romania. All five countries experienced a decline in both animal inventories and meat output during the early years of transition away from a centrally planned economy. ERS, in cooperation with Purdue University, developed five general equilibrium models depicting the economies of each nation. The models were used to evaluate capital investment at different stages of production; the rise in land prices that would result from a better functioning land market; reduced marketing costs; increased availability of credit; and, the creation of off-farm employment to draw labor out of agriculture. The study identifies potential trade and...

NON-TARIFF BARRIERS AND POLITICAL SOLUTIONS TO TRADE DISPUTES: A CASE STUDY OF U.S. POULTRY EXPORTS TO RUSSIA
Provedor de dados: 31
Autores: Ames,   Glenn C.W.
This paper examines the recent U.S.-Russian trade dispute over poultry meats exports.  Russia embargoed U.S. poultry on February 16, 1996, alleging that the U.S. inspection system did not meet Russian standards.  An agreement signed on March 25, 1996, establishing an inspection criteria for exports to Russia and a testing protocol for salmonella and residues, resolved the trade dispute.  Analysis indicates that Arkansas leg quarters prices are closely linked to U.S. poultry exports to Russia.

Chicken Supreme: How the Indonesian Poultry Sector Can Survive Avian Influenza
Provedor de dados: 31
Autores: Vanzetti,   David.
Avian influenza is a deadly disease that can spread rapidly through poultry. There are many documented cases of transmission from birds to people, but as yet only rare instances of human to human transmission. Nonetheless, public health officials are concerned about the possibility of a human pandemic, and many countries have policies of banning imports of live birds and poultry meat from infected regions. The potential impacts on Indonesia of a production shock, a shift in consumption or a trade ban are assessed using a heterogeneous product model where imports are differentiated by source. Empirical results suggest the likely trade impacts in Indonesia are minimal because its trade is a small share of production.

Autores: Lambert,   David K.
Nonparametric procedures are used to compare technological change in SIC 2011, meatpacking, and SIC 2015, poultry slaughter and processing.  There has been a greater increase in total factor productivity in poultry than in the red meats.  Evidence also suggests recent differences in the bias of this technological change, with production changes being labor using in poultry and biased towards greater efficiency in the use of live animal inputs in meatpacking.

Welfare Implications of Selected Supply and Demand Shocks on Producers and Marketers of U.S. Meats
Provedor de dados: 31
Autores: Henneberry,   Shida Rastegari; Mutondo,   Joao E.; Brorsen,   B. Wade.
An equilibrium displacement model is developed and used to estimate the welfare impacts of government and industry-funded promotion programs, country of origin labeling (COOL), and the disease-driven, international bans on U.S. beef. The model goes beyond past studies by including the U.S. domestic market and both U.S. meat imports and exports, with meats differentiated by source of origin. The results indicate that while the benefits from beef and pork promotions are higher, the negative impacts of COOL are lower in a model with international trade than in a model without trade. International bans on U.S. beef decrease the welfare of producers and marketers of U.S. beef.

Provedor de dados: 89
Autores: Saeed,M; Ayaşan,T; Alagawany,M; El-Hack,MEA; Abdel-Latif,MA; Patra,AK.
ABSTRACT The poultry nutritionists constantly attempt to identify and alleviate the factors responsible for adverse effects on nutrient utilization and production performance in avian species, which are necessary for successful productivity of poultry. Enhanced feed utilization can reduce levels of some nutrients in the diet with concomitant mitigation in nutrient excretion into the environment, reduction of eutrophication and acidification potentials of excreta. Commercial enzymes have been used to improve feed efficiency and utilization in poultry. Among many anti-nutritional factors, the existence of ß-mannans in poultry feed ingredients including soybean and other leguminous seeds has been associated with negative effects on nutrient digestibility and...

Autores: Kanashiro,AMI; Stoppa,GFZ; Cardoso,ALSP; Tessari,ENC; Castro,AGM.
Avian salmonellosis is a worldwide problem to the poultry industry, from the point of view of animal health and public health as well. The aim of the present study was to survey the most common Salmonella serovars in commercial breeders or broiler flocks from several regions in Brazil. The results of the present study indicated a high incidence of S enterica subspecies enterica serovar Enteritidis in breeders (57.5%) and broilers flocks (84.0%). The importance of these findings lies in the fact that S. Enteritidis has become the most frequent serovar responsible for foodborne outbreaks and sporadic cases of salmonellosis in humans.

Use of lytic bacteriophages to reduce Salmonella Enteritidis in experimentally contaminated chicken cuts
Provedor de dados: 89
Autores: Fiorentin,L; Vieira,ND; Barioni Júnior,W.
Reducing Salmonella contamination in poultry is of major importance to prevent the introduction of this microorganism into the food chain. Salmonellae may spread during storage time (shelf life) whenever pre-harvest control fails or post-harvest contamination occurs. Therefore, preventive measures should also be used in the post-harvest level of poultry production in order to control salmonellae. Chicken skin samples were experimentally contaminated by immersing whole legs (thighs and drumsticks) in a suspension containing 10(6) colony forming units per milliliter (CFU/mL) of Salmonella Enteritidis phage type 4 (SE PT4) at the slaughter day. One day later, samples from one group were immersed in a suspension pool containing 10(9) CFU/mL of each of three...

ABSTRACT Using disinfectants in poultry houses is a common practice to ban the zoonotic pathogens like Salmonella. A major concern in using disinfectants is the emergence of bacteria strains that resist some disinfectants. This phenomenon is manifested in the resistance of some Salmonella serotypes against quaternary ammonium compounds. Such resistance is attributed to qacEΔ1 gene which may be possessed by some Salmonella serotypes. This work aimed to evaluate the resistance of Salmonella serotypes (S. Typhimurium, S. Infantis and S. Entiridis) against different disinfectants (benzalkonium chloride, iodine, gluteraldehyde and hydrogen peroxide). The effect of the disinfectants were evaluated by treatment of the bacteria with different concentrations...

The objective of this study was to determine the critical points of the operation of broiler catching for transport to the processing plant from animal and operational perspectives. During catching, chickens, environmental variables (temperature and relative humidity) were constantly monitored to determine the Enthalpy Comfort Index (IEC). Also, the physiological variable rectal temperature (RT) was monitored as an indicator of stress suffered by the birds during this handling procedure. Bird welfare were evaluated by analyzing their behavior. The bag method was effective to prevent the struggling of birds while being taken from the broiler house to the transport truck, reducing physical injuries and losses during catching.

Influence of sulfur amino acid levels in diets of broiler chickens submitted to immune stress
Provedor de dados: 89
Autores: Rubin,LL; Ribeiro,AML; Canal,CW; Silva,IC; Trevizan,L; Vogt,LK; Pereira,RA; Lacerda,L.
Several changes in amino acid levels occur during an infection. As a rule, glycine, taurine and serine levels diminish considerably, while cysteine levels increase. Such changes may be attributed to the intense consumption of sulfur amino acids (SAA- methionine+cysteine) during infectious challenge. Methionine plays an important role in humoral and cellular immune responses. It has been suggested that such effect is exerted by intracellular glutathione and cysteine levels. Four-hundred thirty-two day-old Ross male broiler chickens were fed (from 1 to 42 days of age) three SAA levels in the diet (0.72, 0.82, and 0.92% from 1 to 21 days of age; 0.65, 0.75, and 0.85% from 22 to 42 days of age) and submitted to two immunological stimulus series.

Autores: Faria Filho,DE; Dias,AN; Veloso,ALC; Bueno,CFD; Couto,FAP; Matos Júnior,JB; Barreto,KZO; Rodrigues,PA; Carneiro,WA.
This study aimed at determining a specific classification of coefficients of variation in experiments with commercial layers. Coefficients of variation were collected from papers published in Brazilian journals between 2000 and 2009 for performance, internal egg quality, and eggshell quality parameters. The coefficients of variation of each parameter were classified as low, intermediate, high, and very high according to the ratio between the median and the pseudo-sigma. It was concluded that the parameters used in experiments with commercial layers have a specific classification of coefficients of variation, and that this must be considered to evaluate experimental accuracy.

Vertebral Osteomyelitis in Broilers: A Review
Provedor de dados: 89
Autores: Braga,JFV; Martins,NRS; Ecco,R.
ABSTRACT Locomotor diseases are still a challenge in modern poultry. Vertebral osteomyelitis (VO) is an emerging disease in broilers worldwide. The inflammatory process in the affected thoracic vertebra (T4) and subsequent spinal cord compression leads to clinical signs related to locomotor impairment, inadequate feeding and drinking, and increased mortality in the affected flocks. The pathogenesis of the disease is poorly understood and Enterococcus cecorum is the bacterium most frequently associated with the disease. However, other bacteria such as E. faecalis, E. durans, Escherichia coli and Staphylococcus aureus have been recently detected in cases of the disease, raising questions regarding its etiopathogenesis. As many questions about VO in broilers...

Autores: Freitas Neto,OC de; Penha Filho,RAC; Barrow,P; Berchieri Junior,A.
Salmonellosis is a worldwide disease caused by bacteria of the genus Salmonella. Currently, there are over 2,500 identified serovars of Salmonella. A reduced number of these serovars, about eighty, are implicated in most animals and human diseases. Most cases of salmonellosis in humans are associated with the consumption of contaminated food products such as beef, pork, poultry meat, eggs, vegetables, juices and other kind of foods. It may also be associated with the contact between humans and infected pet animals. Therefore, the chain of human salmonellosis is very complex and in most cases the origin of the infection is difficult to establish. The use of antimicrobial agents to treat and to prevent bacterial infections in humans and animals, as well as...

In vitro characterization and in vivo properties of Salmonellae lytic bacteriophages isolated from free-range layers
Provedor de dados: 89
Autores: Fiorentin,L; Vieira,ND; Barioni Júnior,W; Barros,S.
Occurrence of food poisoning related to Salmonella-contaminated eggs and chicken meat has been frequent in humans. Salmonella Enteritidis (SE) and Salmonella Typhimurium (ST) are included among the most important paratyphoid salmonellae associated with chicken meat and eggs. Elimination of Salmonella at the pre-harvest stage can play a significant role in preventing the introduction of this pathogen into the food chain and consequently in the reduction of food poisoning in humans. Bactericidal bacteriophages may provide a natural, nontoxic, feasible and non-expensive component of the multi-factorial approach for a pre-harvest control of Salmonella in poultry. Five bacteriophages lytic for SE PT4 and ST were obtained from 107 samples of feces of free-range...

Autores: Vieira,SL.
Organic minerals have been subject of an increasing number of investigations recently. These compounds can be considered the most significant event regarding commercial forms of minerals targeting animal supplementation in the last decades. Minerals, especially metals, are usually supplemented in poultry feeds using cheap saline sources and have never required a lot of attention in terms of quality. On the other hand, definitions of organic minerals are very broad and frequently lead to confusion when decision-making becomes necessary. Organic minerals include any mineral bound to organic compounds, regardless of the type of existing bond between mineral and organic molecules. Proteins and carbohydrates are the most frequent candidates in organic mineral...

Avian mycoplasmosis update
Provedor de dados: 89
Autores: Nascimento,ER; Pereira,VLA; Nascimento,MGF; Barreto,ML.
Avian mycoplasmas occur in a variety of bird species. The most important mycoplasmas for chickens and turkeys are Mycoplasma gallisepticum (MG), M. synoviae (MS), and M. meleagridis. Besides, M. iowe (MI) is an emerging pathogen in turkeys, but of little concern for chickens. Mycoplasmas are bacteria that lack cell wall and belong to the class Mollicutes. Although they have been considered extracellular agents, scientists admit nowadays that some of them are obligatory intracellular microorganisms, whereas all other mycoplasmas are considered facultative intracellular organisms. Their pathogenic mechanism for disease include adherence to host target cells, mediation of apoptosis, innocent bystander damage to host cell due to intimate membrane contact,...

Nutritional genomics: a practical approach by early life conditioning with dietary phosphorus
Provedor de dados: 96
Autores: Ashwell,Christopher M.; Angel,Roselina.
The recent technologies that have led to the new field of functional genomics (how the genome of an organism regulates homeostasis and responds to stimuli) are providing a clearer understanding of how organisms interact with their environment and in particular their diet. We are beginning to learn how the diet may have long-term influence on performance and health. A form of epigenetic regulation has been recently described called fetal "programming". Fueled by epidemiological data the "fetal origins" hypothesis suggests that a poor in utero environment resulting from maternal dietary or placental insufficiency may "program" susceptibility in the fetus to cardiovascular or metabolic disorders. We have observed similar apparent programming by dietary...

ABSTRACT The objective of this study was to analyze the effect of environmental factors on egg production curve traits in broiler breeders. The weekly egg production records of birds collected from four different flocks were used to estimate the egg production curve parameters using the Compartmental function (y = A(1 − exp−b(t − d))exp−ct). The coefficient of determination (R2) obtained by the model was 0.98. Least squares analysis of variance indicated that the environmental factors such as hatchability and flock had significant effects on egg production curve traits. The highest correlation was observed between the weekly potential maximum yield and yield at the beginning of laying, whereas the lowest correlation was found between the weekly potential...

The objective of this work was to evaluate the inter treatment discrimination according to feed conversion efficiency in several animal performance experiments. The variables investigated were: feed conversion ratio (FCR = intake: production ratio), feed efficiency index (FEI = production: intake ratio) and bio-nutritional index (BNI). The BNI was constructed from the first canonical variable obtained based on the multivariate analysis of variance of the intake and animal production (weight gain or milk production) variables. The results indicated that FCR and FEI reciprocated each other at experimental plot level but did not reciprocate at animal group or treatment level. This fact implicates distortions on the descriptive levels of probability of type I...

ABSTRACT The purpose of this study was to investigate the effects of gosling quality on their growth parameters, intestinal villus morphology, blood biochemistry, and nonspecific pathological lesions from 0 to 4 weeks old. Seventy-two goslings were randomly distributed into 12 pens, with each pen containing three males and three females in a completely randomized design of two control variables, including healthy and weak goslings. Healthy goslings all shared the same characteristics, such as good features with no abnormalities and full absorption of yolk sac. Albeit lighter body weight (&lt;85 g/bird) and incomplete absorption of the yolk sac were found in the weak geese, no obvious disease was exhibited in them. Post mortem examination revealed that the...

Autores: Assunção, Tatiana Reichert da Silva; Palka, Ana Paula Gori; Pavoni, Daniela Parada.
Poultry production is an activity of great importance in Brazilian economy, both due to the domestic consumption and the large amount of chicken meat exportation. Poultry activity modernization allowed the creation of animals in high density facilities, however, it facilitates the rapid dissemination of pathogens, which reduces the productivity rates. This review aims to highlight the avian reovirus, an important agent of arthritis in birds that has a worldwide distribution. The affected birds present a reduction in weight gain due to movement difficulties. In addition to arthritis, the virus may be related to a variety of pathological conditions, such as enteric and respiratory disorders, Hepatitis and myocarditis. The main prevention and control measure...

Autores: Brainer,Mônica Maria de Almeida; Menten,José Fernando Machado; Vale,Marcos Martinez do; Morais,Sônia Cristina Daroz de.
Feeding cupric citrate as alternative to cupric sulfate to broilers has been suggested in the literature. Day-old male broiler chicks (1,200) were used in an experiment to evaluate the efficacy of cupric citrate supplementation (75 mg Cu kg-1) during the 1-21, 22-42 or 1-42 d periods in comparison to an unsupplemented diet and a diet supplemented with cupric sulfate (200 mg Cu kg-1, 1-42 d). A randomized block design was used, with five treatments, six replicates and 40 birds per pen. The diets, based on corn and soybean meal, and water were offered ad libitum during the 42-day experimental period. Over the entire period, there was no effect of copper supplementation (P &gt; 0.05) on bird live weight, weight gain, feed intake, feed conversion and...

Broiler meat quality is one of the primary factors considered by the poultry industry. This study was conducted to estimate heritability and genetic correlation coefficients for meat quality traits in a single male broiler line. The meat ultimate pH (24 h after slaughter) and lightness presented the highest heritability estimates. Given the estimated genetic correlations, the pH measured at 15 min and 24 h after slaughtering, as well as lightness, were characterized by a close and negative genetic relationship with water holding capacity traits. In contrast, meat quality traits exhibited only non-significant genetic correlations with performance and carcass traits. Noticed exceptions were breast weight, which was genetically and favorably associated with...

ABSTRACT: The effects of mycotoxins on the productive performance of growing pigs and broilers were evaluated using meta-analytical approach. Two databases were constructed: (1) Broilers, with information collected from 51,497 birds and published in 158 scientific papers from 1980 to 2016; and (2) Pigs, with information collected from 7,743 animals and published in 72 scientific papers from 1980 to 2015. The meta-analyses were performed independently for each specie, following three sequential analyses: graphical, correlation, and variance-covariance. Broilers and pigs challenged by mycotoxins reduced (p &lt; 0.05) feed intake by 9 and 6 %, weight gain by 15 and 11 %, and feed efficiency by 6 and 4 % compared with non-challenged animals, respectively....

Autores: Iman Valaei; Seyed Reza Hassan-Beygi; Mohammad Hossein Kianmehr; Hadi Rahmanzadeh Bahram.
Dependence on chemical fertilizer is continually increasing.  Continual increasing of using chemical fertilizer causes nature pollution (e.g. water contamination).  This has led researchers to aggressively investigate renewable fertilizer resources and biomass to produce organic crops and reduced wastage.  Poultry litter is a bulk solid and biomass feed stocks. The angle of wall friction (AWF) is a critical factor in designing and constructing suitable equipment for pelletizing.  The results of this study showed that the simple effects of the moisture content (M) and surface types (S) as well as interaction of the S × particle size (P) and S × M were significant (P

Heat and moisture production in growing-finishing pigs and broilers
Provedor de dados: 111
Autores: Aarnink-FBC, Andre.
Heat and moisture production are important parameters for designing ventilation and climate control systems in livestock housing. In 2002 a report was published of the CIGR Section II Working Group on Climatization of Animal Houses ‘Heat and moisture production at animal and house levels’ with formula to calculate heat and moisture production for different livestock categories. The objective of this paper is to discuss these CIGR formula for growing-finishing pigs and broilers. Results from calculated heat and moisture production with the relatively simple formula in the CIGR report were compared with results from a more comprehensive model. From this comparison the following conclusions were drawn: 1) The relatively simple CIGR formula to calculate total...

The Role of Information and Communication Technology in Poultry Broiler Production Process Control
Provedor de dados: 111
Autores: Jackman, Patrick; Penya, Hector; Ross, Robert.
Broiler production is arguably one of the most challenging food supply industries in the world due to the large number of animals that are reared on a given site, and the competitive nature of the sector. These factors taken together mean that every opportunity to optimise the production process must be considered to boost bird weight gain while at the same time reducing resource investment and risk of major incidents. As a result of this, the last decade has seen the introduction of Precision Livestock Farming techniques to the broiler production industry.In this paper we review the emergence and trends in Precision Livestock Farming in the broiler production industry by examining both in-market and laboratory based advances for this sector. The review...

ABSTRACT The effects of increasing levels of soybean acid oil in diets of quails on the quality of eggs were evaluated over a period of 56 days. A completely randomized design with five treatment levels of soybean acid oil (0, 2, 4, 6, and 8%) as a replacer for soybean oil and eight replicates of two quails each were used. A total of 240 fresh eggs were used for quality analysis, and 400 eggs were stored at 23ºC over a period of 0, 7, 14, 21, and 28 days for analysis of shelf-life. Polynomial regression and ANOVA with repeated measurements and Tukey´s tests were used. Soybean acid oil linearly increased the intensity of red (a* = -5.26 + 0.14 x, R2 = 0.89, P = 0.01) and yellow (b* = 42.32 + 0.44 x, R2 = 0.88 P = 0.01). All other variables of egg quality...

Adhesion proteins from Mycoplasma gallisepticum (MG) encoded by cytadhesion genes mgc1 and mgc2 were cloned into plasmid vectors and transformed into E. coli. Seventeen groups of specific-pathogen free (SPF), birds at four weeks of age were used to inoculate these two proteins (MGC1 and MGC2) mixed into an oil emulsion creating a novel MG vaccine. Six different protein concentrations (50, 100, 200, 400, 800, and 1000µg/bird) were tested with two equal concentration doses at four and seven weeks of age. In addition, many control groups were needed such as bacterin, membrane, no vaccine or challenge, oil emulsion alone, and no vaccine but challenged. Three weeks following the second vaccination, 50% of the birds in each treatment group were challenged with...

A new method for analysis of plasma carotenoids in poultry
Provedor de dados: 45
Autores: Teixeira,M.; Meleiro,C.H.A.
A study was carried out to evaluate a new quantitative analytical technique for determination of plasma carotenoids in poultry. Plasma carotenoides were extracted and measured from 30 blood samples of male Cobb broilers. The new technique was efficient in detecting plasma carotenoids of chickens and also showed advantages upon those techniques currently in use such as the form of presentation of results, use of a compatible solvent, and the scanning method for reading. The new technique did not increase the cost of the analysis.

Autores: Moreira,M.A.S.; Moraes,C.A.
One hundred and ninety-seven isolates of Gram-negative bacteria, comprising 10 genera, were isolated from poultry carcasses at a processing plant in order to investigate resistance to low levels of antibiotics. The samples were taken just after evisceration and before inspection. Most of the isolates were of Samonella and Escherichia. Other genera present were Enterobacter, Serratia, Klebsiella, Kluyvera, Erwinia, Citrobacter, Pseudomonas and Aeromonas. Distinct profiles of antibiotic resistance were detected. Resistance to more than two antibiotics predominated and spanned several classes of antibiotics. Salmonellae and escherichiae were mainly resistant to the aminoglycosides, followed by tetracycline, nitrofuran, sulpha, macrolide, chloramphenicol,...

Total RNA isolated from Pectoralis major muscle from PSE (L*24h&gt;53.0, pH&lt;5.8) and non-PSE (44&lt;"L*24h&gt;"53) meats of two phenotypically distinct chicken lines, broiler and layer, was used to investigate the α-ryr and β-ryr gene expression by real-time RT-PCR approach. Mean relative quantification (RQ) values were lower (p&lt;0.05) for β-ryr in PSE chickens from both lines when compared to non-PSE chickens, while there was no difference (p&gt;0.05) in α-ryr gene expression regardless of line studied. The β-ryr RQ results suggested that in PSE samples an alteration might occur in the regular ratio (1:1) of α-RyR/β-RyR normally found in avian muscles. These results provided the first evidence of PSE meat occurrence as a result of the differential...

Autores: Kahraman,Tolga; Issa,Ghassan; Bingol,Enver Baris; Kahraman,Beren Basaran; Dumen,Emek.
The effect of rosemary (Rosmarinus officinalis L.) essential oil (REO) and modified-atmosphere packaging (MAP) on the survival of certain pathogens (Salmonella Typhimurium and Listeria monocytogenes) in poultry fillets and on their meat quality during 7 days of refrigerated storage were investigated. Because REO at 0.05% and 0.1% had weak antibacterial activity and REO at 0.3%, 0.5% and 1.0% imparted unacceptable organoleptic properties, only REO at 0.2% was used to treat the poultry meat. The results showed that adding 0.2% REO to poultry fillets did not reduce the size of the population of S. Typhimurium and L. monocytogenes. However, REO treatment significantly decreased the L* (lightness) value and increased the a* (redness) value of stored fillets,...

The occurrence of fim, pap and sfa operons in Escherichia coli isolated from breeders with salpingitis and chicks with omphalitis was evaluated. Analysis of 100 E. coli isolates, by colony hybridization tests, showed that 78 (78%) were fim+, one (1%) was sfa+, seven (7%) were fim+ associated with pap+, eigth (8%) were fim+ and sfa+, one (1%) was fim+pap+sfa+ and five (5%) isolates did not hybridize with any probe. These results suggest that fim adhesion-encoding operon plays an important role in pathogenesis of E. coli infection in chickens with salpingitis and omphalitis.

Salmonella enterica serovar Gallinarum (SG) is an intracellular pathogen of chickens. To survive, to invade and to multiply in the intestinal tract and intracellularly it depends on its ability to produce energy in anaerobic conditions. The fumarate reductase (frdABCD), dimethyl sulfoxide (DMSO)-trimethylamine N-oxide (TMAO) reductase (dmsABC), and nitrate reductase (narGHIJ) operons in Salmonella Typhimurium (STM) encode enzymes involved in anaerobic respiration to the electron acceptors fumarate, DMSO, TMAO, and nitrate, respectively. They are regulated in response to nitrate and oxygen availability and changes in cell growth rate. In this study mortality rates of chickens challenged with mutants of Salmonella Gallinarum, which were defective in...

In 2003, Brazil was recognized as a pathogenic Newcastle Disease Virus (NDV) strain-free country for commercial poultry. This research was conducted in Brazil between December 2003 and March 2005 to verify the maintenance of this virulent NDV-free status. Serum samples from 5,455 flocks for commercial poultry farms were collected, comprising 81,825 broiler chickens. The farms were located in nine states of the country, grouped in three geographic regions. Serological evidence of NDV infection was detected in 28.8% of the surveyed farms. However, all fifteen viruses isolated and identified as Newcastle Disease Virus (NDV) were characterized as nonpathogenic strains, based on the Intracerebral Pathogenicity Index. These results showed that Brazil preserves...

ABSTRACT Salmonella Enteritidis causes fowl paratyphoid in poultry and is frequently associated to outbreaks of food-borne diseases in humans. The role of flagella and flagella-mediated motility into host-pathogen interplay is not fully understood and requires further investigation. In this study, one-day-old chickens were challenged orally with a wild-type strain Salmonella Enteritidis, a non-motile but fully flagellated (SE ΔmotB) or non-flagellated (SE ΔfliC) strain to evaluate their ability to colonise the intestine and spread systemically and also of eliciting gross and histopathological changes. SE ΔmotB and SE ΔfliC were recovered in significantly lower numbers from caecal contents in comparison with Salmonella Enteritidis at early stages of...

Selection of strains included various criteria such as agreement with bio-safety aspects, viability during storage, tolerance to low pH/ gastric juice, bile, and antimicrobial activity. The strains were isolated from the crop, proventriculus, gizzard, ileum and caeca of chicken. Decimal dilution of the contents of these segments were mixed with MRS medium and incubated for 48 h at 37°C under anaerobiosis. The identity of the culture was based on characteristics of lactobacilli as presented in the Bergey’s Manual of Determinative Bacteriology, carrying out bacterioscopy (morphology), Gram stain, growth at 15 and 45°C, and fermentation of different carbon sources....

Autores: Alves,Osvanira dos Santos; Calixto,Ligia Fatima Lima; Araujo,Alexandre Herculano Borges; Torres-Cordido,Karoll Andrea Alfonso; Reis,Túlio Leite; Calderano,Arele Arlindo.
ABSTRACT: An experiment was performed to evaluate the effect of decreased levels of vitamin D3 in the premix and 1,25-dyhydroxyvitamin D3-glycoside (1,25(OH)2D3-glycoside) supplementation on performance, carcass yield and bone quality in 42d old broilers. Seven-d-old male chickens Cobb500® were distributed in a randomized design with six treatments: a control diet with inclusion of vitamin D3 in the premix, without supplementation of 1,25(OH)2D3-glycoside, and five diets with decreased levels of vitamin D3 (100%, 75%, 50%, 25% and 0% about the control) plus the addition of 1,25(OH)2D3-glycoside, 50g ton-1 of diet. The main results were to reduce the tenor of Vitamin D3 in the premix when the addition of 1,25(OH)2D3-glycoside did not affect (P&gt;0.05) the...

The goals of this research were to estimate the phenotypic correlations among various meat quality traits from a male broiler line and to describe the relation among these variables. Phenotypical correlations were determined among quality traits, isolating the effects of slaughter date, the age of the mother and sex. The evaluated traits were pH measurements taken at time 0 and at 6 and 24 hours after slaughtering, color parameters, water loss due to exudation, thawing and cooking of the meat, and shear force. Important associations (P&lt;0.01) were found to be significant and, in most cases, weak or moderate, varying from -0.35 to 0.28. The initial pH of the meat was not associated (P&amp;gt;0.05) to the other traits of the meat, whereas the pH at 24...

Provedor de dados: 65
Autores: Silva,Rodrigo Otávio Silveira; Oliveira Junior,Carlos Augusto; Guedes,Roberto Maurício Carvalho; Lobato,Francisco Carlos Faria.
Clostridium perfringens is a gram-positive, anaerobic, fermentative, spore-forming bacillus that may be found in the environment but is more commonly found as part of the microbiota of humans and animals. The bacterium is considered a common enteric pathogen; however, the pathogenesis and predisposing factors of the disease can differ among species. Therefore, specific studies are necessary for understanding the role of this pathogen, how to diagnose it and which control measures are applicable. The aim of this paper is to review the current knowledge regarding C. perfringens infections in pigs, horses and broiler chickens

Detection of fluoroquinolone resistance by mutation in gyrA gene of Campylobacter spp. isolates from broiler and laying (Gallus gallus domesticus) hens,from Rio de Janeiro State, Brazil
Provedor de dados: 65
Autores: Frasao,Beatriz da Silva; Medeiros,Valéria; Barbosa,André Victor; de Aguiar,Waldemir Silva; dos Santos,Felipe Faccini; Abreu,Dayse Lima da Costa; Clementino,Maysa Mandetta; de Aquino,Maria Helena Cosendey.
Poultry are considered to be the main reservoir of Campylobacter spp. bacteria, an important pathogen for humans. Many studies have reported a rapid selection of fluoroquinolone-resistant strains following the widespread use of these antimicrobials in poultry production and human medicine. The main mechanism of fluoroquinolone resistance in Campylobacter is a mutation in the Quinolone Resistance Determinant Region (QRDR) in the gyrA gene, which codes for the subunit of the enzyme DNA gyrase, the target for fluoroquinolone. The aim of this study was to investigate the mutation in QRDR in the gyrA gene of Campylobacter strains previously isolated from broiler carcasses and feces of laying hens. Thirty-eight strains of C. jejuni and 19 C. coli strains (n=57),...
