  2. Effects of catching and transportation versus pre-slaughter handling at the abattoir on the prevalence of wing fractures in broilers

    Contributor(s):: Kittelsen, K. E., Granquist, E. G., Vasdal, G., Tolo, E., Moe, R. O.

    Fractures occurring in conscious broiler chickens are painful and severely compromise animal welfare. The aim of this study was to investigate the effects of pre-slaughter handling procedures on the frequency of wing fractures. Wings were examined for fractures in 11,609 broilers, from 12...

  3. Morphological changes in European goldfinches ( Carduelis carduelis ) released by bird trappers

  4. The effects of light intensity and light source on injuries due to pecking of male domestic turkeys ( Meleagris gallopavo )

    Contributor(s):: Moinard, C., Lewis, P. D., Perry, G. C., Sherwin, C. M.

    It has been shown that, in small groups of intact male domestic turkeys, supplementary ultraviolet (UV-A) radiation, visual barriers, and added straw (environmental enrichment) minimize the incidence of injurious pecking under incandescent light at 5 lux. This paper describes two experiments,...
