    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...

  4. A combination of behavioral and physiological indicators for assessing pig welfare on the farm

    Contributor(s):: Candiani, D., Salamano, G., Mellia, E., Doglione, L., Bruno, R., Toussaint, M., Gruys, E.

    The purpose of this research was to identify pig welfare indicators that could help in recognizing stressful practices on farm. The study evaluated behavioral and physiological indicators (cortisol and negative acute phase proteins) in 2 groups of 20 female pigs 4 months old after a 48-hr...

  5. A multidisciplinary approach to assess the welfare of weaned pigs during transport at three space allowances

    Contributor(s):: Sutherland, M. A., Bryer, P. J., Davis, B. L., McGlone, J. J.

    Transport can be a stressful experience for pigs, especially in pigs simultaneously experiencing weaning stress. The objective of this study was to use a multidisciplinary approach to assess the welfare of weaned pigs during transport at 3 space allowances. A commercial semitrailer, fitted with...

  6. Behavioral and hormonal consequences of transporting giant pandas from China to the United States

    Contributor(s):: Snyder, R. J., Perdue, B. M., Powell, D. M., Forthman, D. L., Bloomsmith, M. A., Maple, T. L.

    Zoological institutions strive to ensure the welfare of nonhuman animals in captivity. Part of this effort involves reducing the level of distress experienced by an animal to the greatest extent possible. However, some necessary zoo management practices such as transportation induce stress...

  7. 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...

  8. Effects of training on stress-related behavior of the common marmoset ( Callithrix jacchus ) in relation to coping with routine husbandry procedures. (Training Nonhuman Primates Using Positive Reinforcement Techniques)

    Contributor(s):: Bassett, L., Buchanan-Smith, H. M., McKinley, J., Smith, T. E.

    Using positive reinforcement, 12 common marmosets (Callithrix jacchus) were trained to provide urine samples on request. The marmosets were exposed to mildly stressful, routine husbandry procedures (i.e., capture and weighing). The non-human animals spent less time inactive poststressor as...

  9. Impact of zoo visitors on the fecal cortisol levels and behavior of an endangered species: Indian blackbuck ( Antelope cervicapra L.)

    Contributor(s):: Thangavel, Rajagopal, Govindaraju, Archunan, Mahadevan, Sekar

    This study investigated behavioral activities (resting, moving, aggressive, social, and reproductive behavior) and fecal cortisol levels in 8 individually identified adult male blackbucks during periods of varying levels of zoo visitors (zero, low, high, and extremely high zoo visitor density)....

  10. Minimal number of conspecifics needed to minimize the stress response of isolated mature ewes

    Contributor(s):: Carbajal, S., Orihuela, A.

    The objective of this study was to determine the minimum number of conspecifics that sheep require to minimize the stress associated with isolation from the flock. The study used twelve 3-year-old Suffolk ewes. Every test day, the study randomly selected 1, 2 or 3 ewes to be visually separated...

  11. Physiological arousal for companion dogs working with their owners in animal-assisted activities and animal-assisted therapy

    Contributor(s):: Haubenhofer, D. K., Kirchengast, S.

    This study investigated the physiological reactions of companion dogs (Canis familiaris) used in animal-assisted activities and animal-assisted therapy by measuring salivary cortisol concentrations. The dog caregivers (owners) collected saliva samples (a) at 3 control days without therapeutic...

  12. Physiological responses in wild broodstocks of the Caspian Kutum (Rutilus frisii kutum) subjected to transportation stress

    Contributor(s):: Nikoo, M., Falahatkar, B.

  13. The effect of environmental manipulation on behavior, salivary cortisol, and growth of piglets weaned at 14 days of age

    Contributor(s):: Rodarte, L. F., Ducoing, A., Galindo, F., Romano, M. C., Valdez, R. A.

    Environmental enrichment can be a useful tool to reduce belly nosing behaviors in early weaned piglets. The aim of this study was to assess the effect of environmental enrichment on behavior, salivary cortisol, and productivity of piglets weaned at 14 days of age. The study assigned 112 piglets...

  14. Trailer loading stress in horses: behavioral and physiological effects of nonaversive training (TTEAM)

    Contributor(s):: Shanahan, S.

    Resistance in the horse to trailer loading is a common source of stress and injury to horses and their handlers. The objective of this study was to determine whether non-aversive training based on the Tellington-Touch Equine Awareness Method (TTEAM; Tellington-Jones & Bruns, 1988) would decrease...

  15. Working with rather than against macaques during blood collection. (Training Nonhuman Primates Using Positive Reinforcement Techniques)

    Contributor(s):: Reinhardt, V.

    Training macaques to cooperate during blood collection is a practicable and safe alternative to the traditional procedure implying forced restraint. It takes a cumulative total of about 1 hr to train an adult female or adult male rhesus macaque successfully to present a leg voluntarily and accept...
