| Contributor(s):: Ryan S. Miller, Steven J. Sweeney, Chris Slootmaker, Daniel A. Grear, Paul A. Di Salvo, Deborah Kiser, Stephanie A. Shwif
Cross-species disease transmission between wildlife, domestic animals and humans is an increasing threat to public and veterinary health. Wild pigs are increasingly a potential veterinary and public health threat. Here we investigate 84 pathogens and the host species most at risk for...

Understanding attitude, practices and knowledge of zoonotic infectious disease risks among poultry farmers in Ghana
| Contributor(s):: Matilda Ayim‐Akonor, Ralf Krumkamp, Jürgen May, Eva Mertens
Zoonotic infectious diseases (ZIDs) are increasing globally, and livestock farmers in low‐ and middle‐income countries are at particularly high risk. An evaluation of farmer's behaviour on farms can be used to identify the risk factors and to develop tailored control strategies. This study...
Phenotypic and genomic analyses of agonistic interactions in laying hen lines divergently selected for feather pecking

Testing ultra-wideband technology as a method of tracking fast-growing broilers under commercial conditions
| Contributor(s):: Baxter, Mary, O’Connell, Niamh E.
Ultra-wideband (UWB) is an indoor positioning technology that has several advantages over current methods of tracking indoor reared broiler chickens, including providing long-term data on movement patterns without the effect of observer presence. More information is needed on the accuracy of this...
An Evaluation of Two Different Broiler Catching Methods
| Contributor(s):: Käthe Elise Kittelsen, Erik Georg Granquist, Agnete Lien Aunsmo, Randi Oppermann Moe, Elisiv Tolo
Catching is the first step in the pre-slaughter chain for broiler chickens. The process may be detrimental for animal welfare due to the associated handling. The aim of this pilot study was to compare two different methods to manually catch broilers: Catching the broilers by two legs and...
On-Farm Evaluation of an Automatic Enrichment Device with Maize Silage for Laying Hens
| Contributor(s):: Giersberg, Mona Franziska, Kemper, Nicole, Spindler, Birgit
Challenges in alternative housing for laying hens are barren functional areas such as winter gardens and the occurrence of behavioral disorders. Environmental enrichment is a measure to deal with these problems. Therefore, an enrichment device offering maize silage automatically was tested in two...
Effects of Two CO2 Stunning Methods on the Efficacy of Stunning and Blood Stress Indicators of Turkeys under Commercial Processing Conditions
| Contributor(s):: Guijarro, Angela, Mauri, Soledad, Aviles, Carmen, Peña, Francisco
The effect of CO2 gas-stunning methods (G1: 30% CO2 15 sec, 55% CO2 40 sec, 70% CO2 45 sec; G2: 30% CO2 15 sec, 80% CO2 85 sec) on the efficacy of stunning, blood stress indicators and meat quality of turkeys were assessed. A total of 375 turkeys (125 heavy males, 125 light males, and 125 light...
Effect of simple and low-cost enrichment items on behavioral, clinical, and productive variables of caged laying hens
| Contributor(s):: Frediani, Mayra H., Pizzutto, Cristiane S., Alves, Maíra B. R., Pereira, Ricardo J. G.
Housing layers in battery cages is a practice still used by many countries but it has been criticized because of its influence on behavioral repertoire of birds. We investigated whether simple and affordable enrichment devices alone impact behavior, foot condition and performance of laying hens...
The choice of litter material to promote pecking, scratching and dustbathing behaviours in laying hens housed in furnished cages
| Contributor(s):: Guinebretière, Maryse, Beyer, Helen, Arnould, Cécile, Michel, Virginie
Since 2012 in the EU, cages for the housing of laying hens must provide nests, perches and a pecking and scratching area to promote natural behaviours and enhance animal welfare. Previous studies highlighted the difficulty of finding adequate materials for pecking and scratching areas in such...
Cognitive bias and anticipatory behaviour of laying hens housed in basic and enriched pens
| Contributor(s):: Wichman, Anette, Keeling, Linda J., Forkman, Björn
The performances of adult laying hens, housed in either a basic or an enriched pen, were investigated in a cognitive bias and an anticipation test. Both tests were designed to measure the assumed emotional state of the birds. The behaviour of birds in each test was compared to see whether both...
More eggs but less social and more fearful? Differences in behavioral traits in relation to the phylogenetic background and productivity level in laying hens
| Contributor(s):: Dudde, Anissa, Schrader, Lars, Weigend, Steffen, Matthews, Lindsay R., Krause, E. Tobias
Different lines of laying hens have undergone a strong selection pressure for productivity traits, which has been proposed as a potential cause of undesirable side effects like behavioural disorders. One reason for such behavioral changes might be due to energy trade-offs, as high productive...
An automated positioning system for monitoring chickens’ location: Accuracy and registration success in a free-range area
| Contributor(s):: Stadig, Lisanne M., Ampe, Bart, Rodenburg, T. Bas, Reubens, Bert, Maselyne, Jarissa, Zhuang, Shaojie, Criel, Johan, Tuyttens, Frank A. M.
Free-range use in chickens is often suboptimal, and the full potential of outdoor access for chicken welfare may not be achieved. Many studies use visual observations of free-range use, imposing several limitations. An automated system capable of continuously monitoring the location of multiple...
Indoor side fidelity and outdoor ranging in commercial free-range chickens in single- or double-sided sheds
| Contributor(s):: Rault, Jean-Loup, Taylor, Peta S.
The ranging behaviour of broiler chickens kept in free-range housing systems remains poorly understood, despite access to the outdoor range being their main feature. We investigated the impact of allowing chickens to have range access on both sides vs. one side of the shed, using 24 flocks of...
