  6. Use of outdoor ranges by laying hens in different sized flocks

    | Contributor(s):: Gebhardt-Henrich, Sabine G., Toscano, Michael J., Fröhlich, Ernst K. F.

    In studies assessing outdoor range use of laying hens, the number of hens seen on outdoor ranges is inversely correlated to flock size. The aim of this study was to assess individual ranging behavior on a covered (veranda) and an uncovered outdoor run (free-range) in laying hen flocks varying...

  7. Sheep farmer opinions on the current and future role of veterinarians in flock health management on sheep farms: a qualitative study

    | Contributor(s):: Jasmeet Kaler, L.E. Green

    A 2009 UK Government report on veterinary expertise in food animal production highlighted that there was insufficient herd health expertise among veterinarians and lack of appropriate business models to deliver veterinary services to the livestock sector. Approximately two thirds of sheep farmers...

  8. Population trends of resident and migratory Canada geese in relation to strikes with civil aircraft

    | Contributor(s):: Dolbeer, Richard A., Seubert, John L., Begier, Michael J.

  9. 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...

  10. Plumage damage in free-range laying hens: behavioural characteristics in the rearing period and the effects of environmental enrichment and beak-trimming

    | Contributor(s):: Hartcher, K. M., Tran, M. K. T. N., Wilkinson, S. J., Hemsworth, P. H., Thomson, P. C., Cronin, G. M.

    Severe feather-pecking, whereby birds peck at and pull out the feathers of other birds, is one of the greatest welfare concerns and the most prevalent behavioural problem in laying hens. It can be extremely difficult to control, especially in non-cage laying flocks. Despite a multitude of studies...

  11. The risk factors affecting the development of vent pecking and cannibalism in free-range and organic laying hens

    | Contributor(s):: Lambton, S. L., Knowles, T. G., Yorke, C., Nicol, C. J.

    Injurious pecking remains one of the biggest animal welfare and economic challenges for free-range egg producers. This prospective epidemiological study investigated the development of vent pecking (VP) and cannibalism on 62 free-range and organic UK farms (119 flocks). Flocks were visited at 25...

  13. Zoonoses, public health, and the backyard poultry flock

    | Contributor(s):: Grunkemeyer, V. L.

  14. Changes in substrate access did not affect early feather-pecking behavior in two strains of laying hen chicks

    | Contributor(s):: Dixon, L. M., Duncan, I. J. H.

    Feather pecking, commonly found in flocks of laying hens (Gallus gallus), is detrimental to bird welfare. Thought to cause this problem is the normal housing of layers without a floor substrate. Some evidence suggests that early substrate access decreases later feather pecking. However, there has...

  15. Observing lame sheep: evaluating test agreement between group-level and individual animal methods of assessment

    | Contributor(s):: Phythian, C. J., Cripps, P. C., Grove-White, D., Jones, P. H., Michalopoulou, E., Duncan, J. S.

  16. A non-intrusive method of assessing plumage condition in commercial flocks of laying hens

  19. Differential effects of increased stocking density, mediated by increased flock size, on feather pecking and aggression in laying hens

    | Contributor(s):: Nicol, C. J., Gregory, N. G., Knowles, T. G., Parkman, I. D., Wilkins, L. J.

    Six flocks of laying hens were housed in percheries at 4 stocking densities (6, 14, 22 or 30 birds m-2) from 14 to 30 weeks of age. Stocking density was manipulated by changes in flock size (72, 168, 264 or 368 birds) in percheries with the same floor and height dimensions. The pecking behaviour...

  20. Effect of manipulating feathers of laying hens on the incidence of feather pecking and cannibalism

    | Contributor(s):: McAdie, T. M., Keeling, L. J.

    Feather pecking was studied in 16 groups of 11 Lohmann Brown hens between 26 and 28 weeks of age. The feather pecks were classified separately as either gentle or severe. Damaged feathers received significantly more severe feather pecks than undamaged feathers. There were also more gentle feather...
