  1. Comparison of the effects of weaning and castration when conducted separately or in combination on the behaviour of crossbred beef cattle

    Contributor(s):: Lambertz, Christian, Farke-Röver, Antje, Moors, Eva, Gauly, Matthias

    The objective of the present study was to evaluate the behavioural effects of Burdizzo castration of crossbred beef calves when weaned and castrated separately (castrated 8 weeks after weaning) or in combination. Over two consecutive years a total of 111 Limousin×Simmental male calves were...

  2. "Who's been a good dog?" - Owner perceptions and motivations for treat giving

    Contributor(s):: White, G. A., Ward, L., Pink, C., Craigon, J., Millar, K. M.

    Complex relationships commonly exist between owners and their companion animals, particularly around feeding behaviour with an owner's affection or love for their animal most pronounced through the provision of food. It is notable that the pet food market is experiencing strong year-on-year...

  3. Effect of pre- and post-partum sow activity on maternal behaviour and piglet weight gain 24 h after birth

    Contributor(s):: Illmann, G., Chaloupkova, H., Neuhauserova, K.

    Within the 24 h prior to parturition sows are active and motivated to perform nest-building behaviour. The aim of this study was to investigate: (i) whether pre-partum activity (e.g. nesting and postural changes) could predict maternal behaviour 24 h post-partum (pp) and weight gain 24 h pp, and...

  4. Handling, electric goad, and head restraint: effects on calves' behavior

    Contributor(s):: Goonewardene, L. A., Price, M. A., Stookey, J. M., Day, P. A., Minchau, G.

    96 weaned calves (48 bulls and 48 heifers) were allocated in a 2 x 2 x 2 arrangement to 3 treatments each with 2 levels: calves handled every 10 days or 20 days; an electric goad used or not used; and head gate restrained or not restrained. Behaviour responses were measured by 5 incremental...

  5. An exploratory study on the effects of a straw dispenser in farrowing crates

    Contributor(s):: Bulens, A., Renders, L., Beirendonck, S. van, Thielen, J. van, Driessen, B.

    The effect of a straw dispenser in farrowing crates was investigated to determine the extent to which the provision of small quantities of straw has an influence on both sows and piglets. Sows and suckling piglets are often housed in barren environments with limited opportunities to show behavior...

  6. What is the relationship between level of infection and 'sickness behaviour' in cattle?

    Contributor(s):: Szyszka, O., Kyriazakis, I.

  7. Cross-fostering effects on weight, exploratory activity, acoustic startle reflex and corticosterone stress response in Norway gray rats selected for elimination and for enhancement of aggressiveness towards human

    Contributor(s):: Plyusnina, Irina Z., Oskina, Irina N., Tibeikina, Marina A., Popova, Nina K., Phillips, Tamara

  8. Alternative housing for sows and litters 1. Effects of sow-controlled housing on responses to weaning

    Contributor(s):: Pajor, E. A., Weary, D. M., Fraser, D., Kramer, D. L.

    A sow-controlled housing system and its affects on production and welfare problems resulting from the abrupt separation of piglets from sows at weaning was investigated. 44 sows and litters were housed during lactation in either a 'confined' pen where the sow and litter were kept together, or a...

  9. Alternative housing for sows and litters: 2. Effects of a communal piglet area on pre- and post-weaning behaviour and performance

    Contributor(s):: Weary, D. M., Pajor, E. A., Bonenfant, M., Ross, S. K., Fraser, D., Kramer, D. L.

    An experiment was conducted to determine how allowing piglets access to a communal area affects pre-weaning and post-weaning behaviour and performance. Litters were housed in pens with sows in crates until piglets reached 11 days of age. For 10 experimental cohorts, barriers between the pens of...

  10. Behavioural responses of cattle to shared foraging with wild herbivores in an East African rangeland

    Contributor(s):: Odadi, W. O., Okeyo-Owuor, J. B., Young, T. P.

    We assessed whether prior foraging by wild herbivores affected foraging behaviour of cattle in Laikipia rangeland, Kenya, during February 2001, August 2001 and February 2002. The study compared cattle bite rate, step rate and bites per step in plots exclusively accessible to cattle and those...

  11. Birth weight variation in the domestic pig: effects on offspring survival, weight gain and suckling behaviour

    Contributor(s):: Milligan, B. N., Fraser, D., Kramer, D. L.

    In domestic pigs, litter-mates often vary considerably in birth weight. To examine whether this size variation influences piglet survival, weight gain and suckling behaviour, we experimentally manipulated the number and size distribution of litter-mates in 51 litters. Litters were small (eight or...

  12. Effects of early contact between non-littermate piglets and of the complexity of farrowing conditions on social behaviour and weight gain

    Contributor(s):: Kutzer, T., Bunger, B., Kjaer, J. B., Schrader, L.

    In this study we tested if contact possibilities between non-littermate piglets and complexity of farrowing conditions affect the pre- and post-weaning behaviour, weight gain and skin lesions of piglets. Suckling sows were either kept in a group housing system (GH), in a single pen loose housing...

  13. Influence of artificial vs. mother-bonded rearing on sucking behaviour, health and weight gain in calves

    Contributor(s):: Roth, B. A., Barth, K., Gygax, L., Hillmann, E.

    In artificial rearing, calves are often fed via an automatic milk feeder and have no opportunity to perform natural sucking behaviour. The majority of these calves show abnormal oral behaviours (e.g. cross-sucking). Furthermore, diseases are also a main problem in artificial rearing of calves,...

  14. Influence of post-calving regrouping strategy on welfare and performance parameters in dairy heifers

    Contributor(s):: O'Connell, N. E., Wicks, H. C. F., Carson, A. F., McCoy, M. A.

    Thirty-six Holstein Friesian heifers (dairy herd replacements) were assigned to one of three regrouping treatments during the post-calving period. In Treatment 1, heifers were introduced individually to an established group of cows and heifers within 24 h of calving ('Single - day 1'). In...

  15. Preference testing in intensively kept meat production rabbits for straw on wire grid floor

    Contributor(s):: Morisse, J. P., Boilletot, E., Martrenchar, A.

    384 hybrid commercial breed rabbits were assigned to 16 pens of 1.6 msuperscript 2 (15 rabbits/msuperscript 2). Eight pens used as controls had an all-wire floor, while in 8 other pens, rabbits could choose between a wire floor or a deep litter topped up once a week and completely replaced once...

  16. Social network analysis of behavioural interactions influencing fin damage development in Atlantic salmon ( Salmo salar ) during feed-restriction

    Contributor(s):: Jones, H. A. C., Hansen, L. A., Noble, C., Damsgard, B., Broom, D. M., Pearce, G. P.

    The role of behavioural interactions in the development of fin damage amongst Atlantic salmon (Salmo salar) undergoing feed-restriction was investigated using social network analysis. Dorsal fin damage, particularly erosion, was seen only in groups subjected to feed-restriction. The amount of...

  17. The relationships between temperament during routine handling tasks, weight gain and facial hair whorl position in frequently handled beef cattle

    Contributor(s):: Olmos, G., Turner, S. P.

    A relationship has been described between facial hair whorl position and temperament in infrequently handled beef cattle when both traits were measured on categorical scales. Hair whorl position has also been found to relate to daily weight gain in dairy heifers. Using both a categorical scale...

  18. 'subordination style' in pigs? The response of pregnant sows to mixing stress affects their offspring's behaviour and stress reactivity

    Contributor(s):: Ison, S. H., D'Eath, R. B., Robson, S. K., Baxter, E. M., Ormandy, E., Douglas, A. J., Russell, J. A., Lawrence, A. B., Jarvis, S.

    In various mammals stress during gestation can result in long term effects on the behaviour and physiology of the offspring. The aims of this study were (i) to characterise individual variation among primiparous sows (gilts) in their behavioural and physiological response to a commercially...

  19. Effects of sex, litter size and periconceptional ewe nutrition on the ewe-lamb bond

    Contributor(s):: Hernandez, C. E., Matthews, L. R., Oliver, M. H., Bloomfield, F. H., Harding, J. E.

    Undernutrition restricted to the time around conception in sheep alters endocrine and metabolic responses in the offspring. Studies in rats suggest that such an early insult can also alter the behaviour of the offspring. We studied the effects of mild maternal periconceptional undernutrition...

  20. Effects of social learning on foraging behaviour and live weight gain in first-season grazing calves

    Contributor(s):: Hessle, A. K.

    When livestock are turned out to semi-natural grasslands, an effective onset of grazing is important both for animal productivity and for defoliation of the sward, which preserve the biodiversity of the vegetation. The aim of this study was to investigate whether foraging behaviour of naive...
