Enriched pens were supplied with toys such...

  5. A note: the effects of human handling on heart girth, behaviour and milk quality in dairy goats

    Contributor(s):: Jackson, K. M. A., Hackett, D.

    Research on cattle, lambs and pigs suggests that when animals do not receive positive physical attention ("gentling") from their stockpersons, they become fearful, stressed, less productive, and less healthy overall. The purpose of this experiment was to examine the effects that positive human...

  6. Behavioral agitation during handling of cattle is persistent over time

    Contributor(s):: Grandin, T.

    Fifty-three Gelbvieh X Simmental X Charolais cross bulls and 102 steers were restrained for blood testing every 30 days in a squeeze chute (crush). At the same time they were also weighed in a single animal scale. Out of four consecutive restraint sessions, 5 (9

  7. Behavioural responses of domestic pigs and cattle to humans and novel stimuli

    Contributor(s):: Hemsworth, P. H., Price, E. O., Borgwardt, R.

    Two experiments were conducted on pigs and beef cattle to study whether or not regular exposure to either humans or novel objects resulted in stimulus-specific or generalised behavioural responses. Groups of pigs and cattle were allocated to one of three treatments: regular brief exposure to...

  8. Behavioural responses to humans and the productivity of commercial broiler chickens

    Contributor(s):: Hemsworth, P. H., Coleman, G. J., Barnett, J. L., Jones, R. B.

    A higher proportion of birds that had received minimal human contact withdrew as an experimenter approached in a standard test than birds that had received regular human contact (0.77 vs. 0.46) and these birds that had received minimal human contact had higher plasma corticosterone concentrations...

  9. Cattle with hair whorl patterns above the eyes are more behaviorally agitated during restraint

    Contributor(s):: Grandin, T., Deesing, M. J., Struthers, J. J., Swinker, A. M.

    1500 cattle weighing 180-360 kg were temperament rated on a 4-point scale to determine whether hair whorl position on the forehead is related to a calm temperament. 72% of the cattle were European x British breed crosses and 28% were zebu x dairy breed crosses from Mexico. Cattle with a round...

  10. Conditioned approach-avoidance responses to humans: the ability of pigs to associate feeding and aversive social experiences in the presence of humans with humans

    Contributor(s):: Hemsworth, P. H., Verge, J., Coleman, G. J.

    A series of experiments were conducted to determine whether pigs learn to associate rewarding or aversive elements of a procedure with the handler conducting the procedure. Experiment 1 was conducted to examine whether sexually unreceptive female pigs regularly introduced to boars in their...

  11. Design of loading facilities and holding pens

    Contributor(s):: Grandin, T.

    Holding pens and loading facilities are used in abattoirs, saleyards, stockyards, and sorting facilities. Long, narrow pens are recommended where animals enter through one end and leave through the other. Constructing the pens on a 60-80 degrees angle eliminates sharp 90 degrees corners. Flooring...

  12. Effects of handling at weaning on manageability and reactivity of foals

    Contributor(s):: Lansade, L., Bertrand, M., Boivin, X., Bouissou, M. F.

    The horse's temperament, including its manageability and reactivity and/or fearfulness, is of importance as it can result in problems and can render horses unsuitable for inexperienced riders. Early experience, including handling during infancy, may influence the horse's adult behaviour and...

  13. Effects of neonatal handling on subsequent manageability, reactivity and learning ability of foals

    Contributor(s):: Lansade, L., Bertrand, M., Bouissou, M. F.

    Behaviour is an important factor to be taken into account in the various uses of horses. Today horses are mainly used for sport and leisure activities. They should therefore be easy to manage, calm and not fearful. Early handling is known to improve manageability and learning ability and to...

  14. Effects of regular handling and exposure to an outside area on subsequent fearfulness and dispersal in domestic hens

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

    The effects of regular handling and/or exposure to the outside environment on immature laying hens' fear levels and subsequent readiness to disperse in an outdoor area were investigated. 56 birds, 12 to 20 weeks old, were subjected to (1) no handling plus no outdoor experience (control); (2)...
