Wurm-Befall bei Jungrindern unter trockenen Weidebedingungen
Provedor de dados: 21
Autores: Hertzberg, Hubertus; Maurer, Veronika; Heckendorn, Felix; Wanner, Anne; Gutzwiller, Andreas; Mosimann, Eric.
In einem im Jahr 2003 unter überdurchschnittlich trockenen und warmen Bedingungen durchgeführten Weideversuch mit drei Gruppen von jeweils 20 Jungrindern wurde die Wirkung einer biologischen (Duddingtonia flagrans) und einer medikamentösen (Paratect Flex-Bolus; PFB) Kontrollmethode gegen Befall mit Magen-Darm-Nematoden (MDN) gegenüber einer unbehandelten Kontrollgruppe verglichen. Die meteorologischen Bedingungen führten über direkte (reduzierter Übergang der Infektionsstadien auf die Vegetation; erhöhte Absterberate) und indirekte Faktoren (geringere Besatzdichte, Zufütterung) zu einer deutlichen Verringerung des Infektionsdruckes auf den Versuchsweiden. Daher erwiesen sich weder die medikamentöse noch die biologische Prophylaxestrategie als erforderlich,...

Feeding sainfoin to goats – influence on milk and cheese quality and yield
Provedor de dados: 21
Autores: Heckendorn, Felix; Schwery, Moritz; Volken, Herbert; Maurer, Veronika; Simonnet, Xavier.
Although the administration of sainfoin is associated with anthelmintic effects, information on the consequences of feeding this legume on product quality is scarce. In the present study we looked at milk quality and yield of goats fed either sainfoin or a non-tanniferous control forage. Twelve lactating goats of the alpine breed were used for the study. They received grass/clover hay for a period of 15 days (grass clover feeding period, GCFP). Then the feed was switched to sainfoin hay (approx. 90 % of daily intake) for another 15 days (sainfoin feeding period, SFP). Both feeds were supplemented with concentrates in order to guarantee isoproteic and isoenergetic feeding throughout the trial. Milk yield and quality (fat, protein, energy and urea) were...

Performance d’engraissement de poulets mâles nourris avec différentes sources de protéines
Provedor de dados: 21
Autores: Ammer, Stefanie; Quander, Nele; Posch, Julia; Maurer, Veronika; Leiber, Florian.
Les performances de croissance de mâles d’hybrides de ponte recevant une alimentation comportant des sources et des teneurs différentes en protéines ont été étudiées dans trois essais d’engraissement. Par rapport aux hybrides d’engraissement Hubbard JA 757 (HUB), les poulets mâles des génotypes Lohmann Braun (LB) et Lohmann Selected Leghorn (LSL) présentent une moins bonne performance d’engraissement. Le poids vif, la prise de poids journalière et le poids à l’abattage sont influencés par le génotype.  Les mâles LB présentent cependant de nets avantages en termes de performance par rapport aux mâles LSL. Le remplacement partiel du soja par de la farine de luzerne verte dans les rations, qui s’accompagne d’une réduction de l’apport en protéines, entraîne...

Organic dairy farming and sustainability
Provedor de dados: 21
Autores: Leiber, Florian; Müller, Adrian; Maurer, Veronika; Schader, Christian; Bieber, Anna.
The main cornerstones for enhancing the credibility of the organic dairy sector are: a) to realize an efficient roughage-based production, which requires significantly less inputs from arable land than conventional systems without producing more GHG emissions per unit of products as a whole; b) to enhance dairy cows’ health and welfare, indicated by a clearly improved longevity; and c) to develop the right matches between local conditions (in particular available feed sources) and cow genotypes, in order to achieve functioning systems with the lowest possible need for external nutrient sources.

Biologische Helminthenkontrolle bei Weidetieren mit nematophagen Pilzen
Provedor de dados: 21
Autores: Hertzberg, Hubertus; Larsen, Michael; Maurer, Veronika.
Die Kontrolle gastrointestinaler Nematoden bei Weidetieren basiert seit fünf Jahrzehnten nahezu ausschließlich auf dem Einsatz von Anthelminthika. Die derzeit vor allem bei den Schaf- und Ziegennematoden weltweit zunehmende Resistenzproblematik erfordert die Entwicklung neuer, innovativer Kontrollstrategien, wobei die biologische Bekämpfung auf der Basis nematophager Pilze den derzeit erfolgversprechensten Ansatz darstellt. Erste Versuche zur Anwendung dieser Pilze bei Pflanzen und Tieren erfolgten bereits in den 30er Jahren, doch erst in den 90er Jahren führten Experimente zur Prüfung der Passagefähigkeit einzelner Spezies durch den Magen-Darm-Trakt von Rindern zur Isolation von Duddingtonia flagrans, womit ein maßgeblicher Fortschritt erzielt wurde....

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.

Tanniferous forage plants with anthelmintic properties: the example of sainfoin (Onobrychis viciifolia)
Provedor de dados: 21
Autores: Heckendorn, Felix; Maurer, Veronika; Häring, Dieter; Langhans, Wolfgang; Hertzberg, Hubertus.
Introduction: Sainfoin is a high-quality condensed tannin containing forage plant. The knowledge about anthelmintic effects against sheep nematodes and about the influence of plant preservation (e.g. ensiling) on the anthelmintic activity is limited.  Method: 36 parasite naïve lambs (6 groups of 6 animals each) were infected with H. contortus (7,000 L3) and C. curticei (15,000 L3). From day 28 until day 44 p.i., groups A1, B1 and C1 received fresh, dried or ensiled sainfoin. Groups A2, B2 and C2 served as respective tannin-free controls. Individual faecal egg counts on a dry matter basis (FECDM) were performed every 3-4 days. On day 44, all animals were slaughtered and adult worm populations were determined.  Results: The consumption of sainfoin was...

Haltungsbedingungen, Leistung und Gesundheit von gängigen Legehennen-Genotypen in Öko- und Freilandhaltungen in Frankreich, der Schweiz und den Niederlanden
Provedor de dados: 21
Autores: Maurer, Veronika; Bestman, Monique; van Sambeek, Frans; Leenstra, Ferry.
In Switzerland, France and The Netherlands 257 farmers keeping free ranging laying hens (organic and conventional) were interviewed with regard to genotype of the hens, management conditions and performance. In total, 21 different genotypes were present on the farms. The overall effect of system (organic vs. conventional) on egg production and mortality was significant, with higher mortality and lower egg production among organic hens. White hens tended to perform better and have a better feather cover than brown hens. Silver hens appeared to have a higher mortality and lower production per hen housed. In group discussions, farmers preferred a more robust, heavier hen with good intake capacity and good persistence. In organic systems, this hen type is more...

Übersicht zur alternativen Wurmkontrolle bei kleinen Wiederkäuern
Provedor de dados: 21
Autores: Heckendorn, Felix; Amsler, Zivile; Krenmayr, Ilse; Perler, Erika; Maurer, Veronika.
Gastro-intestinal nematodes (GIN) are the most important problem in small ruminant  production with regard to animal welfare and economics. The control of GIN currently  relies almost exclusively on the use of synthetic anthelmintics. This is unsatisfactory  for organic as well as for conventional small ruminant farmers because of rapid increase  of resistant GIN populations and risk of residues in meat and milk. Alternatives  to synthetic anthelmintics are therefore needed. This poster presents the main alternative  control strategies for GIN. The strategies are divided into measures aimed at freeliving  GIN stages (grazing management, biological control) and at stages within the  host (genetic resistance, vaccination, anthelmintic plants, feeding...

Sainfoin - new data on anthelmintic effects and production in sheep and goats
Provedor de dados: 21
Autores: Heckendorn, Felix; Werne, Steffen; Maurer, Veronika; Perler, Erika; Amsler, Zivile; Probst, Johanna; Zaugg, Cornelia; Krenmeyr, Ilse.
Gastrointestinal nematodes (GIN) are one of the most important problems affecting health and therefore performance and welfare in small ruminant husbandry. The control of these parasites in the past strongly relied on the repeated use of anthelmintic drugs. This has led to nematode populations which are resistant to most of the currently available anthelmintics. Furthermore customer’s demands for organic and residue free animal products are increasing. The aforementioned problems have given a strong impetus for the development of new non-chemical strategies to control GIN. Previous research has pointed out the anthelmintic potential of sainfoin (Onobrychis viciifolia, cv. Visnovsky) and other tanniferous (CT) feed sources in goats and lambs infected with...

Wirken sich Auslauf- und Einstreumanagement auf den Wurmbefall  von Legehennen aus?
Provedor de dados: 21
Autores: Maurer, Veronika; Amsler, Zivile; Perler, Erika; Heckendorn, Felix.
The aim of our experiments was to investigate the transmission and infectivity of the  two main helminth parasites of poultry (Ascaridia galli and Heterakis gallinarum) under  different run and litter management regimes. In experiment (a) two stocking rates were  simulated in outdoor runs and the effect of a simple management practice (mowing)  on helminth transmission was studied during two subsequent flocks. Stocking rate  seemed not to change helminth transmission patterns and repeated mowing of runs  did not reduce helminth infections. Lower stocking rates led to a substantial improvement  of the run vegetation. In experiment (b) two litter management regimes (replace  or add litter material) were compared to unmanaged litter with regard to...

Health and welfare in organic poultry in Europe: state of the art and future challenges.
Provedor de dados: 21
Autores: Bestman, Monique; Maurer, Veronika.
In Europe, over 4 million laying hens and 1.8 million broilers are kept according to the organic principles. Although the regulations are the same for every country, there is a large diversity in farm sizes and farming systems. In Switzerland, 220.000 laying hens are kept on 2100 farms, while in the Netherlands 700.000 hens are kept on 130 farms. In Switzerland, mean mortality is 8%, in the Netherlands mean mortality is 11%, mainly caused by infectious diseases. Regarding animal welfare, feather pecking is seen in 70% of the Dutch and in 50% of the Swiss flocks. Feather pecking has usually started during the rearing period. The main challenges for the future are reducing the vulnerability to diseases and decreasing the amount of feather pecking. In this...

Studies on preventive strategies and alternative treatments against roundworm in organic pig production systems
Provedor de dados: 21
Autores: Borgsteede, Fred H.M.; Gaasenbeek, Cor P.A.; van Krimpen, M.M.; Maurer, Veronika; Mejer, Helena; Spoolder, H. A. M.; Thamsborg, S.M.; Vermeer, Herman M.
Organic and many ‘low input’ production standards for pigs require outdoor access, and as a consequence expose the animals to a wide range of potential endo- and ectoparasite infection sources. Conventional anthelmintics are used to control parasitic infections, but their preventive use is banned by the organic standards. The present paper investigates the potential of prevention of infection through better hygiene. Attempts were made to break the infection cycle through thorough pen cleaning 10 weeks after the pigs had been introduced to the pen. Although pen fouling can be reduced, the level of roundworm (Ascaris  suum) infection was not reduced. Regular deworming with conventional medication is still required in addition to good hygiene.

The plant and animal health care strategy in organic farming strengthensagro-biodiversity, protects the environment as well as animal and human health. In addition to fully exploiting preventive options, the use of external inputs such as plant protection products, fertilisers or veterinarymedicinal productsis allowed to prevent inacceptable losses in productivity or animal suffering. However, external inputs need to comply with organic standardsas well as European legislationand aretherefore carefully evaluated before any decision on  acceptance is taken.Organic farming systems should aim at reducing dependency on off-farm fertilisers to the lowest  feasable level to ensure closed nutrient cycles and avoid nutrient leakage and contamination.

Two different methods to reveal body condition scores (BCS), called independent BCS (iBCS) and dependent BCS (dBCS; similar to the method of Ferguson et al. 1994), were applied in 1111 Swiss Brown dairy cows. Ultrasound measurement of the back fat thickness (BFT) served as validation method. Aim of the study was to evaluate the impact of assessor’s subjective impression of the overall appearance of the cow on the scoring process. With 67.3% of the BFT variance, the dBCS with its consideration of the overall impression of the cow and its more open approach was more suitable to predict the subcutaneous fat appositions. The strictly formularized iBCS could only explain 47.3% of the BFT variance. The pin bone region was identified to cause the biggest...

Biological Control in Organic Production: First choice or last option?
Provedor de dados: 21
Autores: Speiser, Bernhard; Wyss, Eric; Maurer, Veronika.
"Biological agriculture" is a synonym for organic farming, but the term was developed independently from ‘biological control’. Therefore, it cannot be taken for granted that all methods of biological control are acceptable or even a first choice in organic farming. In this chapter, we explore the attitude of organic farming towards methods of biological control. Although organic farming has become popular during the last decade, organic farms are still a minority in all countries.     Furthermore there is a lack of profound knowledge about the regulatory framework for organic farming (i.e. public regulations and private standards). Therefore, we will firstly give a brief introduction to organic farming.

The QLIF project has targeted a variety of issues to make organic animal production (dairy cattle, pig, poultry) more safe, develop alternative methods to promote animal health and improve product quality. This workshop will discuss these aims as well as the QLIF achievements to date. It will also address our way of assessing the quality of our organic farms. We ask the question what the advantages are of doing this by looking at the output of a farm, such as yield, animal welfare and environmental issues. Alternatively, we also want to know what benefits there are in looking at how the farm is organised, via input factors such as housing design, nutrition, management quality. Two invited speakers will state their preference. Legislation, certification and...

Development of prevention and treatment strategies for parasites in poultry
Provedor de dados: 21
Autores: Maurer, Veronika; Amsler, Zivile; Heckendorn, Felix; Perler, Erika.
Parasitic infections are likely to be more important in organic and other free-range hens than in birds kept indoors. Several workpackages of QLIF aim at improving prevention and therapy of helminth (Ascaridia galli and Heterakis gallinarum) and arthropod (Dermanyssus gallinae) parasites of laying hens. This paper is a summary of the work undertaken in the first 3 years of QLIF.

Einfluss von Diäten aus konventioneller und biologischer Erzeugung  auf Fruchtbarkeitsparameter bei Kaninchen
Provedor de dados: 21
Autores: Bieber, Anna; Seidel, Kathrin; Wyss, Gabriela S.; Maurer, Veronika; Zeltner, Esther.
In order to test the effect of organic vs. conventional diets on fertility traits, we conducted  an on-farm study with female rabbits. Eight groups of seven to eight female rabbits  kept in systems with litter were fed ad libitum with either organic or conventional pellets.  Offspring was weaned with approx. 28 days. In the first series analysed, the  conception rate was higher in the conventional groups. Diet type had no significant  influence on that trait. Nevertheless, a significant influence of diet on litter size was  found: organically fed female rabbits produced more offspring per litter. The organic  groups also showed higher rates of weaned animals, despite of a slightly higher mortality  of offspring in these groups, but differences for both...

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...

Distribution of infection with gastro-intestinal nematodes in different groups of dairy goats in Switzerland and its influence on milk production
Provedor de dados: 21
Autores: Grohmann, Markus; Winckler, Christoph; Perler, Erika; Isensee, Anne; Christ, Benedikt; Amsler, Zivile; Werne, Steffen; Maurer, Veronika; Heckendorn, Felix.
The aim of this field study was to investigate interactions between gastro-intestinal nematode (GIN) infection, milk performance and age in goats in order to identify animal groups with higher susceptibility to GIN. On 3 farms (farm A: n = 29, farm B: n = 33, farm C: n = 117 milking goats) fecal egg count reduction tests (FECRT) were performed in summer. All 179 milking goats were enrolled in FECRT and individual milk performance was recorded before and after FEC for FECRT. Furthermore, in early summer and autumn bulk fecal samples were cultured for every farm and GIN genera were determined.

Impact of US Brown Swiss genetics on milk quality from low-input herds in Switzerland: Interactions with season
Provedor de dados: 21

This study investigated the effect of, and interactions between, US Brown Swiss (BS) genetics and season on milk yield, basic composition and fatty acid profiles, from cows on low-input farms in Switzerland. Milk samples (n = 1,976) were collected from 1,220 crossbreed cows with differing proportions of BS, Braunvieh and Original Braunvieh genetics on 40 farms during winter-housing and summer-grazing. Cows with more BS genetics produced more milk in winter but not in summer, possibly because of underfeeding potentially high-yielding cows on low-input pasture-based diets. Cows with more Original Braunvieh genetics produced milk with more (i) nutritionally desirable eicosapentaenoic and docosapentaenoic acids, throughout the year, and (ii) vaccenic and...

This paper reports the results of a seminar on poultry red mite (PRM), Dermanyssus gallinae. Eighteen researchers from eight European countries discussed life cycle issues of the mite, effects of mites on hens and egg production, and monitoring and control methods for PRM in poultry facilities. It was determined that PRM probably causes more damage than envisaged, with the cost in The Netherlands  alone reaching 11 million euro per annum. However a great deal is still unknown about PRM (e.g. reproduction, survival methods, etc.) and that PRM monitoring is an important instrument in recognising and admitting the problem and in taking timely measures. Currently, the most promising control method combines heating the hen house in combination with chemical...

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.

Autores: Heckendorn, Felix; Perler, Erika; Isensee, Anne; Amsler, Zivile; Werne, Steffen; Grohmann, Markus; Uzunoglu, Ferit; Saratsis, Anastasios; Maurer, Veronika; Stricker, Christian.
In Australia and New Zealand the formulation of breeding values for GIN resistance led to large selection programs in sheep successfully improving genetic resistance to GIN. Compared to sheep, the progress with respect to breeding for GIN resistance for various reasons has been much slower in goats. Data on heritabilities of potential auxiliary traits for selection and knowledge about their genetic correlation to production traits is limited. The present Swiss study was designed to fill this gap.  A total of 1.500 goats (20 flocks) of the Alpine and Saanen breed were enrolled in the study. They were individually phenotyped twice for faecal egg count (FEC), FEC of Haemonchus (HCFEC; using fluorescin based differentiation of eggs), FAMACHA eye scores and...

Anthropogenic greenhouse gas emissions have increased since the pre-industrial era, driven largely by economic and population growth, and are now higher than ever. This has led to atmospheric concentrations of carbon dioxide, methane and nitrous oxide that are unprecedented in at least the last 800 000 years. Their effects, together with those of other anthropogenic drivers, have been detected throughout the climate system and are extremely likely to have been the dominant cause of the observed warming since the mid-20th century.

Selection and characterization of ‘low input’ farm groups in 3 macro-climatic regions in Europe for inclusion in a “farmer participatory” performance recording network (FP-PRN) and performance recording of currently used layer genotypes
Provedor de dados: 21
Autores: Leenstra, Ferry; Maurer, Veronika; Bestman, Monique; Zeltner, Esther; van Niekerk, Thea; Galea, Fabien; Reuvekamp, Berry.
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.

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...

Development of integrated livestock breeding and management strategies to improve animal health, product quality and performance in European organic and ‘low input’ milk, meat and egg production
Provedor de dados: 21
Autores: Maurer, Veronika.
The LowInputBreeds project has four main objectives:  - To develop and evaluate innovative breeding concepts to deliver genotypes with ‘robustness’ and quality traits required under ‘low input’ conditions.  - To integrate the use of improved genotypes with innovative management approaches. These will focus on issues where breeding or management innovations alone are unlikely to provide satisfactory solutions e.g. mastitis and parasite control.  - To identify the potential economic, environmental and ethical impacts of the project’s results. The project needs  to ensure that the results are in line with society’s different needs, priorities and consumer expectations.  - To establish an effi cient training and dissemination programme aimed at rapid...

Individual administration of three tanniferous forage plants to lambs artificially infected with Haemonchus contortus and Cooperia curticei
Provedor de dados: 21
Autores: Heckendorn, Felix; Häring, Dieter-Adrian; Maurer, Veronika; Senn, Markus; Hertzberg, Hubertus.
We investigated direct anthelmintic effects associated with the feeding of fresh tanniferous forages against established populations of Haemonchus contortus and Cooperia curticei in lambs. Twenty-four parasite naive lambs were inoculated with a single dose of infective larvae of these two parasites 27 days prior to the start of the feeding experiment. Lambs were individually fed with either chicory (Cichorium intybus), birdsfoot trefoil (Lotus corniculatus), sainfoin (Onobrychis viciifolia) or a ryegrass/ lucerne mixture (control) for 17 days. Animals where then united to one flock and subjected to control feeding for another 11 days to test the sustainability of potentially lowered egg excretion generated by tanniferous forage feeding. When compared to...

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...

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...

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....

Alternatives to Synthetic Chemical Antiparasitic Drugs in Organic Livestock Farming in Europe
Provedor de dados: 21
Autores: Hoste, Hervé; Sotiraki, Smaragda; Mejer, Helena; Heckendorn, Felix; Maurer, Veronika; Thamsborg, Stig.
Gastrointestinal parasitism with helminths and protozoa remains a major threat in cattle and small ruminant production and has been “rediscovered” in pig and poultry production systems operating under organic farming rules because of the requirement to grant outdoor access to the animals. The control of these parasitic infections is a key issue for the economic viability of farms and for animal welfare. Control solutions aim at (i) providing the agronomical bases for parasite control through rational management of pastures; (ii) stimulating the host immune response through different means; (iii) exploring and evaluating the efficacy of new drugs (i.e., phytotherapy, homeopathy and nutraceuticals); and (iv) developing new concepts of application of chemical...

Autores: Leenstra, Ferry; Maurer, Veronika; Bestman, Monique; van Sambeek, Frans; Zeltner, Esther; Reuvekamp, Berry; Galea, Fabien; van Niekerk, Thea.
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...

Search for the ideal laying hen for organic and free range systems
Provedor de dados: 21
Autores: Leenstra, Ferry; Maurer, Veronika; Bestman, Monique; van Sambeek, Frans; Zeltner, Esther; van Niekerk, Thea; Galea, Fabien; Reuvekamp, Berry.
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.
