  1. An observational evaluation of stress in horses during therapeutic riding sessions

    Contributor(s):: McDuffee, L., Carr, L., Montelpare, W.

    Therapeutic riding (TR) provides benefits to participants with cognitive and physical disabilities. Horses participating in TR programs are typically selected because of their calm temperament and may not show obvious signs of stress. However, the welfare of horses in TR programs is an important...

  2. The urinary hormonal state of cats associated with social interaction with humans

    Full-text: Available

    | Contributor(s):: Nagasawa, T., Ohta, M., Uchiyama, H.

    Research to assess the relationship between cats and humans is in a nascent stage. Some studies have assessed the stress status in cats using physiological indicators, such as the cortisol hormone, but have not focused on the social interaction with humans. Moreover, the role of oxytocin...

  3. Exploratory study of fecal cortisol, weight, and behavior as measures of stress and welfare in shelter cats during assimilation into families of children with autism spectrum disorder

    Full-text: Available

    | Contributor(s):: Carlisle, G. K., Johnson, R. A., Koch, C. S., Lyons, L. A., Wang, Z., Bibbo, J., Cheak-Zamora, N.

    Background: Cats are a common companion animal (CA) in US households, and many live in families of children with autism spectrum disorder (ASD). The prevalence of ASD is one in 54, and many children have behavior challenges as well as their diagnostic communication disorders. Objective:...

  7. Positive and negative gestational handling influences placental traits and mother-offspring behavior in dairy goats

    | Contributor(s):: Baxter, E. M., Mulligan, J., Hall, S. A., Donbavand, J. E., Palme, R., Aldujaili, E., Zanella, A. J., Dwyer, C. M.

    Dairy animals are subjected to a number of potential stressors throughout their lives, including daily interactions with humans. The quality of these interactions may have direct consequences for the animal undergoing the experience, but if such events occur during gestation it may also affect...

  8. Reduced heart rate variability in pet dogs affected by anxiety-related behaviour problems

    | Contributor(s):: Wormald, D., Lawrence, A. J., Carter, G., Fisher, A. D.

  9. Impact of structural and cognitive enrichment on the learning performance, behavior and physiology of dwarf goats ( Capra aegagrus hircus)

    | Contributor(s):: Oesterwind, S., Nurnberg, G., Puppe, B., Langbein, J.

    Intensive husbandry usually offers only limited opportunities for animals to perform their characteristic species-specific behavior and can lead to boredom, stress or frustration. The positive impact of structural forms of environmental enrichment on animal welfare is well investigated because it...

  10. 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...

  11. The relationship between individual behavioural styles, dominance rank and cortisol levels of cats living in urban social groups

    | Contributor(s):: Finkler, H., Terkel, J.

    Individual animals show differences in temperament, often correlated with ecologically important behavioural patterns such as dominance, and with physiological responses to environmental perturbations, such as cortisol levels. Identifying these temperaments in animals may reveal adaptive patterns...

  12. An initial investigation into the effects of isolation and enrichment on the welfare of laboratory pigs housed in the PigTurn system, assessed using tear staining, behaviour, physiology and haematology

    | Contributor(s):: DeBoer, S. P., Garner, J. P., McCain, R. R., Lay, D. C., Jr., Eicher, S. D., Marchant-Forde, J. N.

    In some parts of the world, the laboratory pig ( Sus scrofa) is often housed in individual, sterile housing which may impose stress. Our objectives were to determine the effects of isolation and enrichment on pigs housed within the PigTurn - a novel penning system with automated blood sampling -...

  13. Effects of mother versus artificial rearing during the first 12 weeks of life on challenge responses of dairy cows

    | Contributor(s):: Wagner, K., Seitner, D., Barth, K., Palme, R., Futschik, A., Waiblinger, S.

    We investigated the effects of mother versus artificial rearing on the responses to a social and a non-social challenge in adulthood. Rearing of treatment groups only differed during the first 12 weeks of life. Artificially reared animals were separated from their mothers within 24 h after birth...

  14. Young Blond d'Aquitaine, Angus and Limousin bulls differ in emotional reactivity: relationships with animal traits, stress reactions at slaughter and post-mortem muscle metabolism

    | Contributor(s):: Bourguet, C., Deiss, V., Boissy, A., Terlouw, E. M. C.

    The present study investigated relationships between reactivity during tests, stress reactions at slaughter and animal traits in young Blond d'Aquitaine (BA), Limousin (LI) and Angus (AN) bulls. Behavioural and physiological reactivity of animals was evaluated during rearing using a "Human test"...

  15. Physiological effects of human-animal positive interaction in dogs - review of the literature

    | Contributor(s):: Pop, D., Rusu, A. S., Pop-Vancia, V., Papuc, I., Constantinescu, R., Miresan, V.

    Positive human-animal interactions (HAI) are known to increase the quality of life in both humans and dogs. Although there are several reviews on the benefits of HAI in humans, there are no reviews on the effects of positive HAI in dogs. Therefore, the aim of this paper is to provide a review of...

  16. 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...

  17. 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...

  18. 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...

  19. Animal housing and welfare: effects of housing conditions on body weight and cortisol in a medium-sized rodent ( Cavia aperea)

    | Contributor(s):: Schumann, K., Guenther, A., Jewgenow, K., Trillmich, F.

    Rodents are the most abundant experimental nonhuman animals and are commonly studied under standard laboratory housing conditions. As housing conditions affect animals' physiology and behavior, this study investigated the effects of indoor and outdoor housing conditions on body weight and...

  20. 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...
