    Contributor(s):: Duncan, I. J. H., Park, M., Malleau, A. E.

  2. Domestic turkeys are not averse to compact fluorescent lighting

    Contributor(s):: Sherwin, C. M.

    The preferences of 30 male BUT 8 turkeys for 10 lx incandescent or compact fluorescent lighting was determined on 6 occasions when the birds were between 8 and 18 weeks of age. The turkeys showed no indication of aversion to the fluorescent light, rather, they chose this significantly more...

  3. The effects of environmental enrichment and intermittent lighting on the behaviour and welfare of male domestic turkeys

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

    The responses to 4 treatments (2 rooms/treatment) of 8 groups of 50 non-beak trimmed, male domestic turkeys was investigated from day-of hatching to 21 weeks of age. One treatment, 'Control' birds, were reared under conditions close to commercial rearing; the other treatments were Enriched (many...

  4. A brief report on aggressive interactions within and between groups of domestic turkeys ( Meleagris gallopavo )

    Contributor(s):: Buchwalder, T., Huber-Eicher, B.

    Aggressive encounters and injuries due to head pecking seriously threaten the welfare of domestic turkeys and also result in economic waste within the turkey industry. The aim of this study was to investigate whether domestic turkey toms distinguish group members from non-group members and if...

  5. Light intensity preferences of domestic male turkeys

    Contributor(s):: Sherwin, C. M.

    Thirty BUT8 turkey males [15 reared at 4 lux (4LUX) and 15 reared at 12 lux (12LUX)] were placed in a preference apparatus comprising of 4 chambers with a choice of < 1, 5, 10, or 25 lux of light. Sub-groups of 3 birds were tested on 8 occasions between 6 and 19 weeks of age. The 4LUX birds spent...

  6. A note on behaviour of poultry exposed to increasing carbon dioxide concentrations

    Contributor(s):: Gerritzen, M., Lambooij, B., Reimert, H., Stegeman, A., Spruijt, B.

    Killing poultry by means of whole house gassing with carbon dioxide (CO2) is an important tool in disease control. The behaviour of ducks, broilers, laying hens and turkeys was observed to assess differences in susceptibility between species and to assess animal welfare implications following...

  7. Comparisons of damaging feather pecking and time budgets in male and female turkeys of a traditional breed and a genetically selected male line

    Contributor(s):: Busayi, R. M., Channing, C. E., Hocking, P. M.

    Feather and skin pecking leading to feather loss and tissue damage is a welfare problem in commercial turkeys. A factorial experiment was designed to compare a line of unselected turkeys that previously did not exhibit this behaviour with a genetically selected male line with a propensity for...

  8. Behavioural and clinical responses of turkeys stunned in a V-shaped, carbon dioxide tunnel

    Contributor(s):: Hansch, F., Nowak, B., Hartung, J.

    Stunning with carbon dioxide gas (CO2) is used in turkeys (Meleagris gallopavo var domesticus) as an alternative to electrical water bath stunning. Investigations were carried out to assess the behavioural and clinical responses of turkeys stunned in a V-shaped CO2 tunnel while sitting in their...

  9. Behavioural time-budgets and beak related behaviour in floor-housed turkeys

    Contributor(s):: Hughes, B. O., Grigor, P. N.

    The behavioural time budget of 140 turkey poults housed on litter in groups of 10-11 in small pens was recorded by individual scan sampling from 1-day-old to 12-weeks-old. Over this period some behaviour (sitting/sleeping) remained relatively constant, some (feeding) declined and remained low,...

  10. Effects of lighting on the welfare of domestic poultry: a review

    Contributor(s):: Manser, C. E.

    Four aspects of lighting which may affect the behaviour and physiology of housed poultry are light intensity, photoperiod, light source and wavelength. These factors are frequently manipulated in an attempt to improve productivity and to facilitate management practices. This review examines the...

  11. Preferences of growing ducklings and turkey poults for illuminance

    Contributor(s):: Barber, C. L., Prescott, N. B., Wathes, C. M., Sueur, C. le, Perry, G. C.

    The illuminance and spectral power distribution in 19 duckling and 16 turkey poult houses in the UK were sampled. Illuminance was highly variable within duckling houses and to a lesser extent in housing for turkey poults. In a free choice experiment, the preferences of commercial ducklings and...
