  2. Slow and steady wins the race? No signs of reduced welfare in smaller broiler breeder hens at four weeks of age

    Contributor(s):: Lindholm, C., Calais, A., Jonsson, J., Yngwe, N., Berndtson, E., Hult, E., Altimiras, J.

    Broiler breeder chickens are commonly reared under strict feed-restriction regimes to reduce obesity-induced health and fertility problems during adult life, and are assumed to experience a reduced welfare due to the resulting hunger. In these conditions, feed competition could influence the...

  3. The Effects of Owl Decoys and Non-Threatening Objects on Bird Feeding Behavior

    Contributor(s):: Leah Rensel, Jannell Wilder

    As traditional agricultural practices change, the scarecrow has also been renovated and modernized to include mock natural predators, such as owls, hawks, and falcons instead of comical human representations. These facsimiles represent an excellent opportunity to examine anti-predatory tactics...

  4. Condensed tannins reduce browsing and increase grazing time of free-ranging goats in semi-arid savannas

    Contributor(s):: Mkhize, N. R., Heitkonig, I. M. A., Scogings, P. F., Dziba, L. E., Prins, H. H. T., Boer, W. F. de

    Tannin concentrations fluctuate spatially and temporally within and among plant species, with consequences for forage quality of herbivores. The extent to which these fluctuations influence foraging activities of goats is not fully understood. While accounting for the effects of the time of the...

  7. Long-term familiarity creates preferred social partners in dairy cows

    Contributor(s):: Gutmann, A. K., Spinka, M., Winckler, C.

    Group is an essential resource for gregarious animals. Dairy cows are however frequently (re-)grouped according to productivity and reproductive state leading to an unstable social environment for the animals. The present study aimed at investigating whether cows maintain social relationships in...

  8. The effect of a feeding schedule change and the provision of forage material on hair eating in a group of captive baboons ( Papio hamadryas sp.)

    Contributor(s):: Nevill, C. H., Lutz, C. K.

    Hair eating in nonhuman primates is thought to result from a frustrated appetitive drive produced by an inappropriate diet. To investigate whether hair eating could be reduced through changes in diet, a 2-part study was conducted with a group of baboons ( Papio hamadryas sp.). The 1st part...

  9. The effect of four different feeding regimes on rabbit behaviour

    Contributor(s):: Prebble, J. L., Langford, F. M., Shaw, D. J., Meredith, A. L.

    Dietary composition and presentation impacts on the behaviour of animals, and failure to provide a suitable diet can lead to reduced welfare through the development of poor health, the inability to express normal behaviours and the development of abnormal behaviours. This study assessed the...

  10. Innovative Ways to Feed Zoo Animals: Michelle Shaw at TEDxTaipei

    Michelle Shaw received Masters in Comparative Animal Nutrition following her Bachelors from the University of Guelph in Ontario, Canada. She led the animal nutrition for the Toronto Zoo for 10 years, maintained the feeding program and improved the health of wildlife. During that time, she and her...
