  1. A case study: fecal corticosteroid and behavior as indicators of welfare during relocation of an Asian elephant

    Contributor(s):: Laws, N., Ganswindt, A., Heistermann, M., Harris, M., Harris, S., Sherwin, C.

    This study was a preliminary investigation of an enzyme immunoassay for measuring fecal glucocorticoid metabolites in a male Asian elephant (Elephas maximus) by investigating changes in behavior and cortisol metabolite excretion associated with a putative stressful event. The study collected...

  2. Circadian rhythm of salivary cortisol in Asian elephants (Elephas maximus): a factor to consider during welfare assessment

    Contributor(s):: Menargues, A., Urios, V., Liminana, R., Mauri, M.

    Elevated glucocorticoid levels during an extended time period might be a stress indicator in nonhuman animals. Therefore, knowledge of the circadian pattern of cortisol secretion is very important to correctly interpret data obtained for welfare assessment of animals in captivity through salivary...

  3. Effect of work experience and position in the plow harness on some physiological parameters of horses under field conditions

    Contributor(s):: Aguirre, V., Orihuela, A.

    Six pairs of horses were studied during 6 consecutive days. One horse in each pair had working experience. The position of the 2 animals in the plough harness was alternated each day. Some physical and physiological parameters were measured at different stages during each work day. A split-plot...

  4. Frustrated appetitive foraging behavior, stereotypic pacing, and fecal glucocorticoid levels in snow leopards ( Uncia uncia ) in the Zurich Zoo

    Contributor(s):: Burgener, N., Gusset, M., Schmid, H.

    This study hypothesized that permanently frustrated, appetitive-foraging behavior caused the stereotypic pacing regularly observed in captive carnivores. Using 2 adult female snow leopards (U), solitarily housed in the Zurich Zoo, the study tested this hypothesis experimentally with a novel...

  5. 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...

  6. Can non-invasive glucocorticoid measures be used as reliable indicators of stress in animals?

    Contributor(s):: Lane, J.

  7. Environmental enrichment exerts anxiolytic effects in the Indian field mouse (Mus booduga)

    Contributor(s):: Varman, D. R., Ganapathy, Marimuthu, Rajan, K. E.

  8. Factors affecting faecal glucocorticoid levels in domestic cats (Felis catus): a pilot study with single and large multi-cat households

    Contributor(s):: Ramos, D., Arena, M. N., Reche-Junior, A., Daniel, A. G. T., Albino, M. V. C., Vasconcellos, A. S., Viau, P., Oliveira, C. A.

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

    Contributor(s):: Palme, R.

  10. 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...

  11. 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...

  12. Effects of enrichment and housing on cortisol response in juvenile rhesus monkeys

    Contributor(s):: Schapiro, S. J., Bloomsmith, M. A., Kessel, A. L., Shively, C. A.

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

    Contributor(s):: Rushen, J.

  14. Social rank is related to adrenal cortex activity and reproduction in group-housed gilts

    Contributor(s):: Mendl, M., Zanella, A. J., Broom, D. M.

  15. Effects of social environment on welfare status and sexual behaviour of female pigs. II. Effects of space allowance

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

    This study examined the effects of housing groups of adult female pigs (6 pigs per group) with a space allowance of 1, 2 or 3 msuperscript 2 per pig on sexual behaviour and welfare status, determined by plasma free-corticosteroid concentrations. A lower percentage of gilts was detected in oestrus...

  16. 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...

  17. 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...

  18. Behavioural and hormonal responses to acute surgical stress in sheep

    Contributor(s):: Fell, L. R., Shutt, D. A.

    A combination of plasma cortisol and beta -endorphin measurement, behavioural observation and estimation of aversion to humans (by an arena test) was used to assess the response to the modified mules operation in 6- to 7-month-old Merino wethers. The operation involves the surgical removal of...

  19. Effects of social environment on welfare status and sexual behaviour of female pigs. I. Effects of group size

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

    The study examined the effects of housing 24 adult female pigs in groups of 2, 4 or 8 with a space allowance of 1.4msuperscript 2 per pig on welfare status, as indicated by plasma free-corticosteroid concentrations and behaviour patterns, and sexual behaviour. Housing gilts in pairs resulted in...

  20. 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...
