  1. Some effects of repeated handling on stress responses in sheep

    Contributor(s):: Hargreaves, A. L., Hutson, G. D.

    Repeated exposure to a handling treatment was investigated as a possible method of reducing the stress response to shearing. Sheep were exposed to sham shearing (a procedure in which no wool is removed, but which otherwise resembles shearing) on 4 occasions at 2-week intervals. The peak cortisol...

  2. Stereotypies, adrenal function and neurophysiological aspects of gestating sows

    Contributor(s):: Borell, E. von, Hurnik, J. F.

  3. Stress hormone responses of sheep to food and water deprivation at high and low ambient temperatures

    Contributor(s):: Parrott, R. F., Lloyd, D. M., Goode, J. A.

    Eight Clun Forest wethers were used to study the effects of feed and/or water deprivation at different ambient temperatures (7 or 35 degrees C) on stress hormone release. Blood samples were taken from catheterized animals at the start and at 6 h intervals during 48 h tests in an environmental...

  4. Stress response of working African elephants to transportation and safari adventures

    Contributor(s):: Millspaugh, T. T., Burke, T., Dyk, G. van, Slotow, R., Washburn, B. E., Woods, R. J.

    African elephants (Loxodonta africana) are intensively managed in southern Africa and are routinely translocated between reserves. Domesticated elephants are used for elephant-back safaris and interactions with guests. Understanding how elephants respond to such activities is critical because of...

  5. Studies on oral stereotypies in restricted-fed broiler breeders

    Contributor(s):: Savory, C. J.

  6. The effect of orientation during trailer transport on heart rate, cortisol and balance in horses

    Contributor(s):: Clark, D. K., Friend, T. H., Dellmeier, G.

    Sixteen same-sex pairs of Quarter Horse and Quarter Horse-cross yearlings (8 pairs during each of 2 trials, 1 year apart) were transported for 17.8 +or- 0.52 min over a standard course with one horse facing in the direction of travel and one facing the opposite direction. The orientation of the...

  7. The effects of aversively handling pigs, either individually or in groups, on their behaviour, growth and corticosteroids

    Contributor(s):: Hemsworth, P. H., Barnett, J. L.

    The influence of three handling treatments, imposed for 10 weeks from 15 kg liveweight, on the behaviour, growth, subsequent reproductive performance and free corticosteroid concentrations were studied in 60 female pigs. The pleasant treatment involved individually handling the pig in a pleasant...

  8. The effects of design of individual stalls on the social behaviour and physiological responses related to the welfare of pregnant pigs

    Contributor(s):: Barnett, J. L., Hemsworth, P. H., Winfield, C. G.

    Plasma free-corticosteroid concentrations, aggressive behaviour and levels of motivation to interact socially and explore a novel environment were observed to test the hypothesis that the chronic stress response previously observed in tether-housed pigs may have been due to unresolved aggression...

  9. The effects of genotype on physiological and behavioural responses related to the welfare of pregnant pigs

    Contributor(s):: Barnett, J. L., Hemsworth, P. H., Cronin, G. M., Winfield, C. G., McCallum, T. H., Newman, E. A.

    Plasma free-corticosteroid concentrations, aggressive behaviour and levels of motivation to interact socially and explore a novel arena were observed in an experiment to examine whether differences previously observed between pigs in neck-tethers and groups are shown by pigs of different...

  10. The effects of housing experience on calf responses to handling and transport

    Contributor(s):: Trunkfield, H. R.

  11. The effects of social interaction and environmental enrichment on the space use, behaviour and stress of owned housecats facing a novel environment

    Contributor(s):: Rehnberg, L. K., Robert, K. A., Watson, S. J., Peters, R. A.

    Every day, millions of domestic cats are held temporarily in captive environments, such as boarding catteries and rescue shelters. Being in confinement can potentially invoke high levels of stress for these animals. Therefore, there is a need to develop appropriate strategies to reduce these...

  12. The stress response in sheep during routine handling procedures

    Contributor(s):: Hargreaves, A. L., Hutson, G. D.

    Five routine handling treatments (shearing, crutching, drenching, dipping and drafting) were imposed on groups of 30 Merino wethers. Haematocrit and plasma cortisol were measured as an indication of the physiological stress response. Both parameters were significantly elevated after shearing...

  13. The welfare of adult pigs: the effects of five housing treatments on behaviour, plasma corticosteroids and injuries

    Contributor(s):: Barnett, J. L., Cronin, G. M., Winfield, C. G., Dewar, A. M.

    The effects of 5 housing treatments (tethered, pairs, or a group indoors, in a yard or in a paddock) on the behaviour, physiology (stress physiology and blood metabolites), health (injury status) and production (food eaten and oestrous expression) of 30 non-pregnant adult female pigs were...

  14. The welfare of pigs in two farrowing/lactation environments: cortisol responses of sows

    Contributor(s):: Cronin, G. M., Barnett, J. L., Hodge, F. M., Smith, J. A., McCallum, T. H.

    Plasma free cortisol concentrations were measured in 24 primiparous sows housed from day 104 after mating up to day 2 after parturition. Concentrations were measured in 22 of these sows during days 2-29 of lactation, housed in either commercial farrowing crates, or farrowing pens with straw. The...

  15. Therapy dogs' salivary cortisol levels vary during animal-assisted interventions

    Contributor(s):: Glenk, L. M., Kothgassner, O. D., Stetina, B. U., Palme, R., Kepplinger, B., Baran, H.

  16. Using fecal hormonal and behavioral analyses to evaluate the introduction of two sable antelope at Lincoln Park Zoo

    Contributor(s):: Loeding, E., Thomas, J., Bernier, D., Santymire, R.

    Introductions of sable antelope (Hippotragus niger) can be difficult due to the potential ensuing aggression compounded by their large horns. The goal was to use hormonal assays and behavioral analyses to evaluate the success of an introduction of 2 adult females at Lincoln Park Zoo. The...

  17. Weaning and separation stress: maternal motivation decreases with litter age and litter size in farmed mink

    Contributor(s):: Malmkvist, Jens, Sørensen, Dennis D., Larsen, Torben, Palme, Rupert, Hansen, Steffen W.

    The optimal timing of separating the mink dam from the litter is suggested to be a balance between the partly conflicting needs of the mother and the kits. Early removal of the dam or partial removal of the litter may protect the dam against exhaustion. Little is, however, known about dam stress...
