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...

Baker, S. W., Tucci, E. R., Felt, S. A. et al. 2019. A bird's-eye view of regulatory, animal care, and training considerations regarding avian flight research. Comparative Medicine 69(3), 169–178.

A thorough understanding of how animals fly is a central goal of many scientific disciplines. Birds are a commonly used model organism for flight research. The success of this model requires studying healthy and naturally...

The poultry team at The Pirbright Institute reviewed existing husbandry practices and trialled several refinement practices. The objective was to provide the birds used in research with an environment which enables them to express their...

Shi, H., Li, B., Tong, Q. et al. 2019. Influence of nest boxes and claw abrasive devices on feather pecking and the fear responses of layer breeders in natural mating colony cages. Applied Animal Behaviour Science 220, 104842.

Natural mating colony cages for parent-stock layer breeders, instead of conventional cages with artificial insemination, have been widely adopted by many commercial farms in China. Although some natural mating behaviours can be expressed and broader...

Bach, M. H., Tahamtani, F. M., Pedersen, I. J. et al. 2019. Effects of environmental complexity on behaviour in fast-growing broiler chickens. Applied Animal Behaviour Science 219, 104840.

Modern broiler chickens spend a great proportion of their time resting, which poses a major threat to their welfare due to the increased risk of contact dermatitis and the incidence and severity of leg problems...
