Nie, C., Ban, L., Ning, Z. et al. 2019. Feather colour affects the aggressive behaviour of chickens with the same genotype on the dominant white (I) locus. PLOS ONE 14(5), e0215921.

Aggression in chickens is a serious economic and animal welfare issue in poultry farming. Pigmentation traits have been documented to be associated with animal behaviour. Chicken pecking behaviour has been found to be related to...

Campderrich, I., Nazar, F. N., Wichman, A. 2019. Environmental complexity: A buffer against stress in the domestic chick. PLOS ONE 14(1), e0210270.

Birds kept in commercial production systems can be exposed to multiple stressors from early life and this alters the development of different morphological, immunological and behavioural indicators. We explore the hypothesis that provision of a...

Bracke, M. B. M., Koene, P., Estevez, I. et al. 2019. Broiler welfare trade-off: A semi-quantitative welfare assessment for optimised welfare improvement based on an expert survey. PLOS ONE 14(10), e0222955.

In order to support decision making on how to most effectively improve broiler welfare an innovative expert survey was conducted based on principles derived from semantic modelling. Twenty-seven experts, mainly broiler welfare scientists (n =...

Bertin, A., Mocz, F., Calandreau, L. et al. 2019. Human behaviour at the origin of maternal effects on offspring behaviour in laying hens (Gallus gallus domesticus). Physiology & Behavior 201, 175-183.

Regular visual presence of humans is known to reduce chickens' human-generated stress responses. Here we questioned whether, more than mere visual presence, human behaviour affects laying hen behaviour and subsequently their offspring's behaviour. We hypothesized...

Zepp, M., Louton, H., Erhard, M. et al. 2018. The influence of stocking density and enrichment on the occurrence of feather pecking and aggressive pecking behavior in laying hen chicks. Journal of Veterinary Behavior 24, 9-18.

The housing conditions and environments experienced during the rearing period can influence the development of feather pecking in chickens during this time and in the subsequent laying period. The aim of this study was to...

Ali, A. B. A., Campbell, D. L. M., Karcher, D. M. et al. 2019. Daytime occupancy of resources and flooring types by 4 laying hen strains in a commercial-style aviary. Journal of Veterinary Behavior 31, 59-66.

In response to consumer demands and legislative measures for improving hens' welfare, many laying hen producers are replacing conventional cages with aviaries. Aviary resources, such as nest boxes, litter areas, ledges, and perches, are intended...

Meng, F., Chen, D., Li, X. et al. 2017. The effect of large or small furnished cages on behaviors and tibia bone of laying hens. Journal of Veterinary Behavior 17, 69-73.

This study aimed to investigate the effects of large furnished cages (LFCs) or small furnished cages (SFCs) on behavior and tibia bone of laying hens. Three hundred and sixty Hyline brown hens at 16 weeks...

Vinco, L. J., Archetti, I. L., Giacomelli, S. et al. 2016. Influence of crate height on the welfare of broilers during transport. Journal of Veterinary Behavior 14, 28-33.

Poultry transport systems are currently under investigation with a particular focus on design and dimensions of commercially available transport crates. The height of the crates currently used is debated and considered by some parties to...

Giersberg, M. F., Kemper, N., Spindler, B. 2019. On-farm evaluation of an automatic enrichment device with maize silage for laying hens. Journal of Applied Animal Welfare Science 22(4), 309-319.

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...

Edwards, G. L., Michael, J. A., Parks., A. 2018. Agricultural animals as biomedical models: Occupational health and safety considerations. ILAR Journal 59(2), 161-167.

The use of agricultural animals in biomedical research is increasing. Their overall size and metabolic rate, organ size, longer gestation period, and other physiological similarities make them good candidates for animal models of human disease...
