  1. 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...

  2. Tailored enrichment strategies and stereotypic behavior in captive individually housed macaques ( Macaca spp.)

    Contributor(s):: Cannon, T. H., Heistermann, M., Hankison, S. J., Hockings, K. J., McLennan, M. R.

    The welfare of nonhuman animals in captivity is widely dependent on the natural psychological, physical, and behavioral needs of the animals and how adequately these needs are met. Inability to engage in natural behaviors can lead to chronic stress and expression of stereotypic behavior. The...

  3. 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...

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

    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...

  6. 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...

  7. 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,...

  8. 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...

  9. Use of dynamic and rewarding environmental enrichment to alleviate feather pecking in non-cage laying hens

    Contributor(s):: Daigle, C. L., Rodenburg, T. B., Bolhuis, J. E., Swanson, J. C., Siegford, J. M.

    Feather pecking (FP) can cause feather loss, resulting in physical injuries, which may lead to cannibalism. FP appears to be a redirection of foraging behavior, which intensifies when hens have difficulty coping with stress and fear. Dynamic environmental enrichment (EE) may allow expression of...

  10. 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...

  11. 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...

  12. 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...
