  1. Repeated separations between a future guide dog and its foster family modify stress-related indicators and affect dog's focus

    Contributor(s):: Menuge, F., Marcet-Rius, M., Chabaud, C., Teruel, E., Berthelot, C., Kalonji, G., Bienboire-Frosini, C., Mendonca, T., Lascar, E., Pageat, P.

    Contributor(s):: Schwere, R.

  3. Using the incidence and impact of health conditions in guide dogs to investigate healthy ageing in working dogs

    Full-text: Available

    | Contributor(s):: Caron-Lormier, G., England, G. C. W., Green, M. J., Asher, L.

    This study aimed to use retirement data from working guide dogs to investigate healthy ageing in dogs and the demographic factors that influence ageing. Using a dataset of 7686 dogs spanning 20 years, dogs withdrawn for health reasons before they reached retirement were identified. Cases of...

  4. A new metric for quantifying the relative impact of risk factors on loss of working life illustrated in a population of working dogs

    Full-text: Available

    | Contributor(s):: Caron-Lormier, G., Harvey, N. D., England, G. C. W., Asher, L.

    In a resource-limited world, organisations attempting to reduce the impact of health or behaviour issues need to choose carefully how to allocate resources for the highest overall impact. However, such choices may not always be obvious. Which has the biggest impact? A large change to a small...

  5. Evaluating stress in riding horses: part one - behavior assessment and serum cortisol

    | Contributor(s):: Hovey, M. R., Davis, A., Chen, S., Godwin, P., Porr, C. A. S.

  6. Evaluation of effects of olfactory and auditory stimulation on separation anxiety by salivary cortisol measurement in dogs

    Full-text: Available

    | Contributor(s):: Yoon-Joo Shin, Nam-Shik Shin

    Separation anxiety (SA) is a serious behavioral problem in dogs. In this study, salivary cortisol was studied to determine if the owner's odor or voice could reduce SA in dogs. Twenty-eight dogs with SA were divided into three groups: group 1 (control), group 2 (with owner's clothes...

  7. Cortisol levels in dolphin Tursiops truncatus interactive programs linked to humanNiveles de cortisol en delfines Tursiops truncatus vinculados a programas interactivos con humanos

    | Contributor(s):: Sanchez Okrucky, R., Morales Vela, B.

    Understanding the physiological changes in animals during physical activity to improve animal welfare has become increasingly important in animal collections that remain under human care. To date, the effect of interactive programs on dolphins under human care has not been evaluated, for that...

  8. 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...

  9. Application of the welfare quality protocol in pig slaughterhouses of five countries

    | Contributor(s):: Dalmau, A., Nande, A., Vieira-Pinto, M., Zamprogna, S., Martino, G. di, Ribas, J. C. R., Costa, M. P. da, Halinen-Elemo, K., Velarde, A.

    The objective of the present study is to assess the variability of the measures used in the welfare quality (WQ) protocol for pigs among slaughterhouses in five different countries and to propose alarm and critical thresholds for the calculation of scores for future development of an animal...

  10. A randomized cross-over exploratory study of the effect of visiting therapy dogs on college student stress before final exams

    | Contributor(s):: Barker, S. B., Barker, R. T., McCain, N. L., Schubert, C. M.

    This exploratory study investigated the effect of visiting therapy dogs on college-student perceived and physiological stress the week prior to final exams. Students ( n=78) were randomly assigned to order of a therapy-dog intervention and attention-control condition, each 15 minutes long....

  11. 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...

  12. 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...

  13. Human-domestic animal interactions

    | Contributor(s):: Broom, D. M., Fraser, A. F.

  15. Study on blood physiology characteristics in working dogs

    | Contributor(s):: Yang, JiaQiang, Cao, JingFeng, Du, XiaoPeng, Kong, XiaoYan, Yan, DaWei

    Adult working dog has to do a lot of intense physical training every day. The blood physiology and hemorheological indexes were measured in three adult working dogs (Kunming, German shepherd, Belgian malinois) and one indigenous breed in Kunming. The results showed that the number of red blood...

  16. Energy intake and expenditure of improvised explosive device detection dogs

    | Contributor(s):: Phillips, S. P., Kutzner-Mulligan, J., Davis, M.

    Improvised explosive device detection (IDD) dogs explore up to 40 km of land daily and therefore have energetic demands that may be above the National Research Council's requirement for working dogs. This study was designed to quantify metabolic energy intake (MEI) and total energy expenditure...

  17. 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...

  18. Understanding feeding patterns in growing pigs by modelling growth and motivation

    | Contributor(s):: Boumans, I. J. M. M., Bokkers, E. A. M., Hofstede, G. J., Boer, I. J. M. de

    Feeding is an essential behaviour for body maintenance in pigs and closely related to their growth and productivity performance. Mechanisms underlying feeding behaviour in pigs are still unclear. Understanding these mechanisms can provide valuable insights into the complex interactions among...

  19. 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,...

  20. The camel today: assets and potentials

    | Contributor(s):: Faye, B.

    Although they quantitatively only take a marginal place amongst domestic herbivores (only 0.4% of world domestic herbivores), the large camelids (dromedary and Bactrian) are present in almost all the arid lands of the old world (except in Southern Africa), a widespread area of over 35 millions km...
