A plea to implement robustness into a breeding goal: poultry as an example
Contributor(s):: Star, L., Ellen, E. D., Uitdehaag, K., Brom, F. W. A.
The combination of breeding for increased production and the intensification of housing conditions have resulted in increased occurrence of behavioral, physiological, and immunological disorders. These disorders affect health and welfare of production animals negatively. For future livestock...
The ethics and politics of animal welfare in New Zealand: broiler chicken production as a case study
Contributor(s):: Morris, M. C.
The cause of poor welfare in broilers is multifactorial, but genotype is a major contributor. Modern broilers have been bred for rapid growth, and this leads to increases in lameness and ascites as the legs and hearts of the heavier birds find it difficult to cope with the extra demands placed on...
The ethics and politics of the caged layer hen debate in New Zealand
Changes in attitudes toward animal welfare, with a greater emphasis on the importance of allowing animals to express normal patterns of behavior has led to an examination of the practice of keeping hens in battery cages. There is widespread scientific consensus that the conditions of confinement...
Animal welfare: should we change housing to better accommodate the animal or change the animal to accommodate the housing?
Contributor(s):: Cheng, Heng-Wei
Animal welfare (well-being) can be generally defined as 'a state of harmony between the animal and its environment, characterized by optimal physical, behavioural and psychological functioning and high quality of the animal's life'. Since its inception in the early nineteenth century, through...
Reflection paper on MRSA in food-producing and companion animals: epidemiology and control options for human and animal health. (Special Issue: Epidemiology of methicillin-resistant Staphylococcus aureus with emphasis on veterinary and community sett

The scope of this reflection paper was to review the latest research on the risk of MRSA infection and colonization in animals. Attention focused on occurrence, risk factors for colonization and infection, and human contact hazard for livestock, horses, and companion animals. Whereas the clonal...
A cross-sectional study of the prevalence of vent pecking in laying hens in alternative systems and its associations with feather pecking, management and disease
Contributor(s):: Potzsch, C. J., Lewis, K., Nicol, C. J., Green, L. E.
The aim of this cross-sectional study was to investigate associations between vent pecking (VP) and management in laying hens in alternative systems and to compare the results with those from the feather pecking (FP) analysis using data collected in the same study. The data were derived from a...
Accuracy of laying hens in jumping upwards and downwards between perches in different light environments
Contributor(s):: Moinard, C., Statham, P., Haskell, M. J., McCorquodale, C., Jones, R. B., Green, P. R.
Eighty Lohmann Brown layer hens were reared in floor pens fitted with perches from 1 day of age. After the peak of lay (25 weeks of age), their ability to jump to and from perches in different light environments was assessed in two experiments using digital video techniques that allowed detailed...
Agonistic behaviour and feather pecking in single-sexed and mixed groups of laying hens
Contributor(s):: Oden, K., Vestergaard, K. S., Algers, B.
The effects of the presence of males on female aggressiveness and feather pecking in groups of about 500 laying hens housed in an aviary system were studied. In all, 10 groups of ISA Brown laying hens were observed at 21, 35, 45 and 55 weeks of age on 2 farms, during 2 years. In the second year,...
Altered aggression in different sized groups of crayfish supports a dynamic social behaviour model
Contributor(s):: Patullo, B. W., Baird, H. P., Macmillan, D. L.
Living in groups with conspecifics can increase an animal's fitness in the wild. A social environment may also be imposed by commercial farming industries. One important measure of competition and group dynamics is the level of aggressive interaction. This can also influence the level of damage...
Are genetic differences in foraging behaviour of laying hen chicks paralleled by hybrid-specific differences in feather pecking?
Contributor(s):: Klein, T., Zeltner, E., Huber-Eicher, B.
Feather pecking is a behavioural disorder in laying hens which consists of pecking the feathers of conspecifics, causing feather damage or even injuries to the skin. Its development can be explained by redirection of foraging behaviour. While the occurrence of feather pecking strongly depends on...
