  1. Influence of housing on weanling horse behaviour and subsequent welfare

    Contributor(s):: Heleski, C. R., Shelle, A. C., Nielsen, B. D., Zanella, A. J.

    Weaning foals marks a stressful event in horses' lives. Limited research exists regarding different housing methods post-weaning and the long-term implications on horse behaviour and welfare. The purpose of this study was to monitor behaviour and physiological stress markers in horses weaned...

  2. Influence of indoor-cat group size and dominance rank on urinary cortisol levels

    Contributor(s):: Lichtsteiner, M., Turner, D. C.

    Domestic cats (Felis silvestris catus) are often housed indoors both singly and in groups. However, there is a lack of studies dealing with cat-cat relationships, group composition and effects of environmental parameters on the well-being of privately-owned cats. One way to index the effects of...

  3. Measuring faecal glucocorticoid metabolites as a non-invasive tool for monitoring adrenocortical activity in South American camelids

    Contributor(s):: Arias, N., Requena, M., Palme, R.

  4. Monitoring stress hormone metabolites as a useful, non-invasive tool for welfare assessment in farm animals

    Contributor(s):: Palme, R.

  5. Neonatal handling of Amazon parrots alters the stress response and immune function

    Contributor(s):: Collette, J. C., Millam, J. R., Klasing, K. C., Wakenell, P. S.

    The influence of neonatal handling on behaviour and immune function was assessed in Orange-winged Amazon parrots (Amazona amazonica). Chicks (n=11) were gently handled daily from 25 days of age until 38 days post-fledging, while control chicks (n=9) were not handled. At 10 days post-fledging...

  6. Novel box breeding has variable effects on heart rate and cortisol response of cattle

    Contributor(s):: Lay, D. C., Friend, T. H., Grissom, K. K., Hale, R. L., Bowers, C. L.

    In 7 experiments, cattle of different sex classes (bulls, steers, and cows), age (2-10 years), and breed (Angus, Hereford, and Braford) were subjected, one at a time, to restraint by a standard squeeze chute (cattle crush) or a novel 'breeding box' in order to compare each method's effects on...

  7. Pain and stress in crustaceans? (Special Issue: Animal suffering and welfare.)

    Contributor(s):: Elwood, R. W., Barr, S., Patterson, L.

    We consider evidence that crustaceans might experience pain and stress in ways that are analogous to those of vertebrates. Various criteria are applied that might indicate a potential for pain experience: (1) a suitable central nervous system and receptors, (2) avoidance learning, (3) protective...

  8. Pet ownership and asthma morbidity

    Contributor(s):: Simpson, A. J., Matusiewicz, S. P., Greening, A. P., Crompton, G. K.

  9. Physiological and behavioural aspects of assessing stress and welfare in the pig

    Contributor(s):: Barnett, J. L.

  10. Physiological and behavioural effects of handling and restraint in the ball python ( Python regius ) and the blue-tongued skink ( Tiliqua scincoides )

    Contributor(s):: Kreger, M. D., Mench, J. A.

    Four handling techniques commonly used with snakes and lizards in zoological park reptile collections were evaluated with respect to animal well-being. Adult male blue-tongued skinks (n = 3) and ball pythons (n = 4) were either handled gently, restrained manually, or container restrained for 10...

  11. Postweaning grouped sows: effects of aggression on hormonal patterns and oestrus behaviour

    Contributor(s):: Pedersen, L. J., Rojkittikhun, T., Einarsson, S., Edqvist, L. E.

    The concentration of cortisol, oestradiol-17 beta , prolactin and the amount of social behaviour shown during oestrus were measured in 3 groups of 3 sows (Swedish X Swedish Yorkshire) grouped after weaning and correlated with aggressive behaviour. No relations between the amount of aggression...

  12. Problems associated with the interpretation of physiological data in the assessment of animal welfare

    Contributor(s):: Rushen, J.

  13. Program animal welfare: using behavioral and physiological measures to assess the well-being of animals used for education programs in zoos

    Contributor(s):: Baird, Bonnie A., Kuhar, Christopher W., Lukas, Kristen E., Amendolagine, Laura A., Fuller, Grace A., Nemet, James, Willis, Mark A., Schook, Mandi W.

    This study investigates program animal welfare using both behavioral and physiological measures in two separate experiments. In Experiment One, we examined possible differences in behavior and fecal glucocorticoid metabolites (FGM) between education, exhibit and off-exhibit armadillos ( N=59)...

  14. Providing 'get-away bunks' and other enrichments to primiparous adult female mink improves their reproductive productivity

    Contributor(s):: Buob, M., Meagher, R., Dawson, L., Palme, R., Haley, D., Mason, G.

  15. Rapid shaping of behaviour associated with high urinary cortisol in domestic dogs

    Contributor(s):: Blackwell, E. J., Bodnariu, A., Tyson, J., Bradshaw, J. W. S., Casey, R. A.

    The occurrence of stress has widely been associated with impairments in learning abilities in animals, although the influence of stress appears to differ with the complexity of tasks. Previous research has suggested that some domestic dogs exhibit both physiological (elevated cortisol) and...

  16. Reactions of cattle to head-restraint at stunning: a practical dilemma

    Contributor(s):: Ewbank, R., Parker, M. J., Mason, C. W.

    The behavioural reactions and blood cortisol levels of cattle stunned using a penetrating captive-bolt pistol whilst standing free in a stunning box were compared with those obtained from cattle similarly stunned but with their heads held in a hydraulically operated chin-lift type of head...

  17. Repeated transport and isolation during pregnancy in ewes: differential effects on emotional reactivity and weight of their offspring

    Contributor(s):: Roussel-Huchette, S., Hemsworth, P. H., Boissy, A., Duvaux-Ponter, C.

    The aim of this experiment was to study the effects of different stressors applied to pregnant ewes during the last third of pregnancy on the emotional reactivity of their lambs. Forty ewes were subjected twice a week during the last 6 weeks of gestation to 10 sessions of isolation (ISOL, n=20)...

  18. Salivary cortisol in pigs after adrenocorticotrophin, food and water deprivation, handling, transport simulation and mixing

    Contributor(s):: Parrot, R. F., Misson, B. H., Baldwin, B. A.

  19. Social behaviour and adrenal cortical activity in heifers

    Contributor(s):: Adeyemo, O., Heath, E.

    Heifers of the German Brown Swiss, Holstein and White Fulani cattle were observed before, during and after a training. Individual and social behaviour were observed while the animals were under free housing in the pen, grazing in the paddock and while filing through the crush and the passage...
