  3. Selection for temperament in sheep: Domain-general and context-specific traits

    Contributor(s):: Beausoleil, Ngaio J., Blache, Dominique, Stafford, Kevin J., Mellor, David J., Noble, Alasdair D. L.

    Sheep at the University of Western Australia have been selectively bred for behavioral responses to isolation and human presence in an arena test, resulting in the creation of two divergent lines: More Active (MA) and Less Active (LA). The aim of this study was to determine whether selection was...

  4. Use of behavioural and physiological responses for scoring sound sensitivity in dogs

    Full-text: Available

    | Contributor(s):: Carla Caroline Franzini de Souza, Daniel Penteado Martins Dias, Raquel Nascimento de Souza, Magda Alves de Medeiros

    Sound sensitive dogs have exaggerated responses to sound stimuli that can negatively impact the welfare of the dog. Behavioural reactions combined with the response to sound involve a marked autonomic imbalance towards sympathetic predominance and release of cortisol. The purpose of the present...

  5. Oxytocin and Cortisol Levels in Dog Owners and Their Dogs Are Associated with Behavioral Patterns: An Exploratory Study

    Full-text: Available

    | Contributor(s):: Maria Petersson, Kerstin Uvnäs-Moberg, Anne Nilsson, Lise-Lotte Gustafson, Eva Hydbring-Sandberg, Linda Handlin

    We have previously shown that dog–owner interaction results in increasing oxytocin levels in owners and dogs, decreasing cortisol levels in owners but increasing cortisol levels in dogs. The present study aimed to further investigate whether oxytocin and cortisol levels in the previously...

  6. Cortisol and Secretory Immunoglobulin A Response to Stress in German Shepherd Dogs

    Full-text: Available

    | Contributor(s):: Ivona Svobodová, Helena Chaloupková, Roman Koncel, LudÄ›k Bartoš, Lenka Hradecká, Lukáš Jebavý

    The aim of the study was to determine whether cortisol and secretory Immunoglobulin A (sIgA) could be used as an indicator of acute stress in both young and adult dogs. Seventeen German shepherd puppies were exposed to the Puppy test (challenge test) at the age of seven weeks. This test has...

  7. Training Reduces Stress in Human-Socialised Wolves to the Same Degree as in Dogs

    Full-text: Available

    | Contributor(s):: Angélica da Silva Vasconcellos, Zsófia Virányi, Friederike Range, César Ades, Jördis Kristin Scheidegger, Erich Möstl, Kurt Kotrschal

    The welfare of animals in captivity is of considerable societal concern. A major source of stress, especially for wild animals, is the lack of control over their environment, which includes not being able to avoid contact with human beings. Paradoxically, some studies have shown that...

  8. The Effectiveness Of Enrichment Programs For Dogs In An Animal Shelter

    | Contributor(s):: Pamela Perry

    Dogs (N = 108) in an animal shelter received one of four enrichment programs: twice daily walking alone (walking) or in combination with a daily fooddispensing toy (toy), a daily session of standardized human contact (petting), or daily obedience training (obedience). We evaluated the effects of...

  9. 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...

  10. 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...

  11. 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...

  12. 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...

  13. 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)....

  14. 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...

  15. 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...

  16. 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...

  17. 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...

  18. Randomized trial examines effects of equine facilitated learning on adolescents' basal cortisol levels

    Full-text: Available

    | Contributor(s):: Patricia Pendry, Annelise N. Smith, Stephanie M. Roeter

    Although equine facilitated programs have gained in popularity over the last decade, virtually nothing is known about the causal effects of equine facilitated interventions on human development and well-being. Researchers conducted a randomized trial to determine the effects of an 11-week...
