The European Union ban on conventional cages for laying hens: history and prospects
Contributor(s):: Appleby, M. C.
Since the publication of "Animal Machines" (Harrison, 1964), there has been widespread public pressure in Europe - supported by European institutions - to "ban the battery cage." The European Union (EU) and national governments (particularly in Northern Europe) funded research on noncage systems...
Using conjoint analysis to weight broiler welfare variables based on slaughterhouse data
Contributor(s):: Tuunainen, P., Valaja, J., Valkonen, E., Hepola, H.
The Council of the European Union adopted the welfare directive for broiler chickens in 2007 (Commission of the European Communities, 2007). The directive defines minimum demands and objectives for broiler production ranging from stocking density to welfare. This study found that the level of...
Welfare, health, and hygiene of laying hens housed in furnished cages and in alternative housing systems
Contributor(s):: Rodenburg, T. B., Tuyttens, F. A. M., Sonck, B., Reu, K. de, Herman, L., Zoons, J.
The aim of this review was to compare welfare, health, and hygienic status of laying hens housed in furnished cages and in alternative systems. In alternative systems (floor housing and aviaries), birds have more freedom of movement and a more complex environment than in furnished cages. However,...
Incorporating the philosophy of technology into animal welfare assessment
Contributor(s):: Daigle, C. L.
Changes in attitudes towards how animals are housed in agriculture are currently under question in the public eye - particularly for laying hens. Many arguments from the rights and utilitarian viewpoints have been made for changing environmental conditions and managerial practices for animals in...
Aggressiveness in the domestic fowl: Distance versus 'attitude'
Contributor(s):: Rodriguez-Aurrekoetxea, A., Estevez, I.
It has been suggested that invasion of the personal space by flock members is the main trigger of aggressive interactions in the domestic fowl ( Gallus gallus domesticus). In large and dense groups of birds high frequency of attacks should be expected as the chances of invading the personal space...
BIOETHICS SYMPOSIUM II: current factors influencing perceptions of animals and their welfare
Contributor(s):: McKendree, M. G. S., Croney, C. C., Widmar, N. J. O.
To address escalating concerns about livestock animal care and welfare it is necessary to better understand the factors that may predispose people to develop such concerns. It has been hypothesized that experiences with, beliefs about, and emotional connections to animals may influence level of...
Lameness is consistently better at predicting broiler chicken performance in mobility tests than other broiler characteristics
Contributor(s):: Caplen, G., Hothersall, B., Nicol, C. J., Parker, R. M. A., Waterman-Pearson, A. E., Weeks, C. A., Murrell, J. C.
To determine whether lame broilers are in pain it is necessary to compare measures of lameness and mobility before and after analgesic treatment. Such measures should not be unduly affected by other bird characteristics. This study assessed the performance of lame (gait score, GS 3-4) and...

Close human presence reduces avoidance behaviour in commercial caged laying hens to an approaching human
Contributor(s):: Edwards, L. E., Coleman, G. J., Hemsworth, P. H.
The quality of human contact that hens are exposed to will determine the degree of fear of humans that they experience. This has consequences for the welfare of commercial laying hens, as hens that are afraid of humans will be regularly exposed to a fear-provoking stressor. Hens can be habituated...
