| 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... |

| 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... |

| 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. |

| 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. |

| 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... |

| The aim of this trial was to study the effect of organic housing system on the behaviour, productive performance and the qualitative characteristics of eggs. The experiment was conduced directly in the field on Hy-Line laying hens from the beginning of the productive period (17 weeks of age) till the end of productive career. The animals were divided in two homogeneous groups and assigned to the following housing system: control, conventional cage (18 bird/m2) and organic 6 birds m2 in a covered straw-bedded house with access to a paddock (4 m2/bird). A standard feed with the same nutritive characteristics was given ad libitum to the chickens. For the organic, more than 80% of the ingredients (maize, wheat and whole soybean) were organically grown, as... |

| 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 < 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.... |

| This study was conducted to determine the effect of the air temperature variation on the mean surface temperature (MST) of 7- to 35-day-old broiler chickens using infrared thermometry to estimate MST, and to study surface temperature variation of the wings, head, legs, back and comb as affected by air temperature and broiler age. One hundred Cobb® broilers were used in the experiment. Starting on day 7, 10 birds were weekly selected at random, housed in an environmental chamber and reared under three distinct temperatures (18, 25 and 32 ºC) to record their thermal profile using an infrared thermal camera. The recorded images were processed to estimate MST by selecting the whole area of the bird within the picture and comparing it with the values obtained... |

| Welche Rinder, Schweine, Hühner braucht der ökologisch wirtschaftende Betrieb? Welche geeigneten Rassen stehen zur Verfügung, und welche Ansätze gibt es, um Tiere mit den gewünschten Eigenschaften zu züchten? Welche Strukturen müssen dazu aufgebaut werden? Um diese Fragen geht es in einem von der Zukunftsstiftung Landwirtschaft organisierten und im Rahmen des Bundesprogramms Ökologischer Landbau geförderten Projekt. Mit ihm sollen die Aktivitäten für eine ökologische Tierzucht ermittelt, vernetzt, die Notwendigkeit des Aufbaus eigenständiger Strukturen geprüft und Zuchtverbände und Zuchtunternehmen für eine Öko-Züchtung gewonnen werden. Der Text stellt bisher gewonnene Ergebnisse des laufenden Projektes vor. Inhalt: Ökologische Rinderzucht: Von... |

| 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... |

| Für den Bereich der Züchtung und Aufzucht von Legehybriden im ökologischen Landbau wird die Diskrepanz zwischen Zielen und Entwicklungsstand aufgezeigt. Die Zuchtfirmen der Legehybriden beginnen, den Markt alternativer Haltungssysteme wahrzunehmen. Die ökologische Aufzucht befindet sich in Bezug auf Umfang und Tiergerechtheit noch in den Kinderschuhen. Im Rahmen eines mehrjährigen Projekts, das Legehybriden unter Praxisbedingungen des ökologischen Landbaus vergleicht, werden Bedingungen und Leistungen einer Aufzucht dargestellt und ausgewertet. Je eine Gruppe brauner Legehybriden der Linien Dekalb Gold, Shaver Starcross 577-SL und Tetra-SL wurde auf einem Aufzuchtbetrieb des ökologischen Landbaus aufgezogen. Am Versuch waren 3099 Tiere beteiligt (Dekalb:... |

| 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... |

| Problemstellung/Ziele: Bereits jetzt werden in der Schweiz etwa die Hälfte der Legehennen mit Grünauslauf gehalten. Meist ist jedoch nur ein kleiner Teil der Tiere draussen und diese befinden sich hauptsächlich im stallnahen Bereich (Hirt et al. 2000). Durch die ungleichmässige Landnutzung besteht ein erhöhter parasitärer Druck auf die Die genetische Herkunft der Tiere beeinflusst verschiedene Faktoren. Es konnte festgestellt werden, dass verschiedene Hybriden unterschiedliches Erkundungsverhalten haben (Klein et al. 2000). Craig, et al. (1983) fanden Hybridunterschiede in der Nervosität und im Furchtverhalten. Die ängstlichere Linie hatte auch grössere Gefiederschäden. Beim Federpicken konnten ebenfalls je nach Hybrid eine unterschiedliche Häufigkeit... |
