  1. Hair cortisol concentrations, as a measure of chronic activity within the hypothalamic-pituitary-adrenal axis, is elevated in dogs farmed for meat, relative to pet dogs, in South Korea

    Contributor(s):: Maxwell, N. B., Buchanan, C. G., Evans, N. P.

  2. Hair cortisol concentrations in New Zealand white rabbits subjected to surgery

    Contributor(s):: Peric, T., Comin, A., Corazzin, M., Montillo, M., Canavese, F., Stebel, M., Prandi, A.

  3. Factors determining the effects of human interaction on the cortisol levels of shelter dogs

    Contributor(s):: Willen, Regina M., Mutwill, Alexandra, MacDonald, Lauren J., Schiml, Patricia A., Hennessy, Michael B.

    The stress experienced by dogs admitted to animal shelters not only impacts welfare, but may lead to behavior that threatens successful adoptions. This stress is reflected in an elevation in the plasma cortisol levels of newly admitted dogs. We previously found 30min of human interaction reduced...

  4. White Blood Cell Counts, Parasite Prevalence, and Plasma Cortisol Levels of Dogs in a County Animal Shelter: Changes over Days and Impact of a Program of Repeated Human Interaction

    Contributor(s):: Emily S. Dudley

    Animal shelter housing is highly stressful for a dog, compromising welfare and leading to undesirable behaviors and unknown health consequences. We documented the changes in circulating numbers of white blood cells, plasma cortisol, and fecal parasite shedding of dogs housed for 10 days at a...

  5. Experimental verification of the effects on normal domestic cats by feeding prescription diet for decreasing stress

    Contributor(s):: Miyaji, K., Kato, M., Ohtani, N., Ohta, M.

    The objective of this study was to evaluate the effects of diet on the feline stress response by measuring plasma and urinary cortisol. A study diet was developed with a unique combination of nutrients that supports the management of stressful situations. The specific formulation of the diet...

  6. The effects of drug detection training on behavioral reactivity and blood neurotransmitter levels in drug detection dogs: a preliminary study

    Contributor(s):: Riva, J., Marelli, S. P., Redaelli, V., Bondiolotti, G. P., Sforzini, E., Santoro, M. M., Carenzi, C., Verga, M., Luzi, F.

    The aim of the present study was to analyze the effects of drug detection training on behavior and blood neurotransmitter levels in drug detection dogs so as to investigate some variables influencing dog reactivity and responsiveness to training. In all, 20 dogs were sampled out of the Guardia di...

  7. Dog handlers' and dogs' emotional and cortisol secretion responses associated with animal-assisted therapy sessions

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

  8. Acute effects of cow-calf separation on heart rate, plasma cortisol and behaviour in multiparous dairy cows

    Contributor(s):: Hopster, H., O'Connell, J. M., Blokhuis, H. J.

    Removing the calf after bonding may induce acute stress in the dairy cow. The responses of 8 Holstein-Friesian cows were examined immediately after the removal of their calves on the third day after parturition. Blood samples were taken before and after the separation for cortisol analysis. After...

  9. The effect of diet on cribbing behavior and plasma beta -endorphin in horses

    Contributor(s):: Gillham, S. B., Dodman, N. H., Shuster, L., Kream, R., Rand, W.

    Five cribbing horses and six control horses were used in a latin square design dietary study to investigate the effects of different diets on the frequency of cribbing behaviour and plasma levels of beta-endorphin. Feeding grain or sweetened grain rations significantly increased the cribbing...
