  1. Effects of freeze or hot-iron branding of Angus calves on some physiological and behavioural indicators of stress

    Contributor(s):: Lay, D. C., Friend, T. H., Grissom, K. K., Bowers, C. L., Mal, M. E.

    Twenty-four Angus calves averaging 293 +or- 38 kg either hot-iron branded (H), freeze branded (F), or served as a sham (S). Calves were grouped for temperament, weight, and sex, and randomly assigned to day and order in which treatments were applied. To reduce stress from handling at treatment...

  2. Effects of Sheltering on Behavior and Fecal Corticosterone Level of Elderly Dogs

    Contributor(s):: Katsuji Uetake, Chu Han Yang, Aki Endo, Toshio Tanaka

    In Japan, the human population is aging rapidly, and the abandonment of dogs by the elderly people who have died or been hospitalized becomes a problem. It is hypothesized that elderly dogs have difficulty adapting to the novel circumstances when brought to an animal shelter. Therefore, the...

  3. 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...

  4. 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...

  5. Effects of visual contact with zoo visitors on black-capped capuchin welfare

    Contributor(s):: Sherwen, S. L., Harvey, T. J., Magrath, M. J. L., Butler, K. L., Fanson, K. V., Hemsworth, P. H.

    Previous research has suggested that the presence of zoo visitors may be stressful for various primate species, and visual contact with visitors may be the sensory stimuli that mediate visitor effects. We studied a group of black-capped capuchins, Cebus apella, in a controlled experiment,...

  6. Effects of vitamin C supplementation on the adrenocortical and tonic immobility fear reactions of Japanese quail genetically selected for high corticosterone response to stress

    Contributor(s):: Satterlee, D. G., Jones, R. B., Ryder, F. H.

    Japanese quail chicks (18 days of age), from a line genetically selected for high plasma corticosterone response to brief immobilization stress, were treated for 24 h with either untreated drinking water or with a vitamin C (1200 mg/l of ascorbic acid: AA) solution. The chicks were subsequently...

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

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

  8. Environmental enrichment for maned wolves ( Chrysocyon brachyurus ): group and individual effects

    Contributor(s):: Vasconcellos, A. S., Guimaraes, M. A. B. V., Oliveira, C. A., Pizzutto, C. S., Ades, C.

    Procedures that increase foraging and exploratory behaviours are generally accepted as effective at improving welfare and reducing stereotypies in captive animals. To determine the effect of food and toy enrichment on the behaviour and hormonal levels of maned wolves (Chrysocyon brachyurus), 11...

  9. Environmentally enriching American mink ( Neovison vison) increases lymphoid organ weight and skeletal symmetry, and reveals differences between two sub-types of stereotypic behaviour

    Contributor(s):: Diez-Leon, M., Bursian, S., Galicia, D., Napolitano, A., Palme, R., Mason, G.

    Enrichment studies for wild carnivores (e.g., in zoos) are often short-term, use enrichments of unknown motivational significance, and focus on glucocorticoids and stereotypic behaviour (SB), ignoring other stress-relevant variables. Our study assessed the broad behavioural and physiological...

  10. Euthanasia methods, corticosterone and haematocrit levels in Xenopus laevis : evidence for differences in stress?

    Contributor(s):: Archard, G. A., Goldsmith, A. R.

    Amphibians, like other vertebrates, respond to acute stressors by releasing glucocorticoid steroid hormones that mediate physiological and behavioural responses to stress. Measurement of stress hormones provides a potential means to improve the welfare of laboratory animals. For example,...

  11. Events around weaning in semi-feral and stable-reared Konik polski foals: evaluation of short-term physiological and behavioural responses

    Contributor(s):: Gorecka-Bruzda, A., Suwala, M., Palme, R., Jaworski, Z., Jastrzebska, E., Boron, M., Jezierski, T.

    The annual weaning, stabling and subsequent sale of semi-feral Konik polski foals born in forest reserves ensure a stable population of free-roaming Konik polski horses. However, welfare concerns regarding the maternal and herd separation of young horses, manipulation by humans, transportation...

  12. 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.

  13. Faecal glucocorticoid level is not correlated with stereotypic pacing in two captive margays ( Leopardus wiedii )

    Contributor(s):: Gusset, M.

    The 'coping hypothesis' of stereotypic behaviour - that stereotypies are performed as a means of helping the animal to cope with its environment by reducing stress - was tested using two adult female margays (Leopardus wiedii), an endangered neotropical small cat species. Within-individual and...

  14. Fecal concentrations of cortisol, testosterone, and progesterone in cotton-top tamarins housed in different zoological parks: relationships among physiological data, environmental conditions, and behavioral patterns

    Contributor(s):: Fontani, S., Vaglio, S., Beghelli, V., Mattioli, M., Bacci, S., Accorsi, P. A.

    The aim of this investigation was to study the welfare of 3 captive groups of cotton-top tamarins housed in different zoological parks. Ethological observations were conducted during 1 year. In addition, fecal samples were collected and the concentrations of glucocorticoids, androgens, and...

  15. Frequency of headshaking in White Leghorn chickens in response to hormonal and environmental changes

    Contributor(s):: Dunnington, E. A., Siegel, P. B.

    Frequency of headshaking in chickens from two selected lines (HA and LA) known to differ in this trait was observed at various ages, during hormonal fluctuations and in different environmental surroundings. Neither hormonal changes concomitant with the initial onset of lay nor ingestion of...

  16. 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...

  17. Hormonal and behavioural stress responses to capture and radio-collar fitting in free-ranging pampas deer ( Ozotoceros bezoarticus)

    Contributor(s):: Munerato, M. S., Marques, J. A., Caulkettt, N. A., Tomas, W. M., Zanetti, E. S., Trovati, R. G., Pereira, G. T., Palme, R.

    This study evaluated the short-term hormonal and behavioural responses to capture and radio-collar fitting in free-ranging pampas deer ( Ozotoceros bezoarticus). Twenty adult deer (eleven females and nine males) were captured in the South Pantanal wetland (Brazil) and equipped with VHF...
