1. Effect of Cage Type on Fecal Corticosterone Concentration in Buck Rabbits During the Reproductive Cycle

   Contributor(s):: Cornale, Paolo, Macchi, Elisabetta, Renna, Manuela, Prola, Liviana, Perona, Giovanni, Mimosi, Antonio

   Fecal corticosterone concentration (FCC) was measured in 14 buck rabbits individually housed in standard-dimension cages (SC) or in bigger cages (BC; with a volume more than double that of SC and equipped with a plastic foot mat) during 4 consecutive reproductive cycles. Cage type and...

2. Weaning and separation stress: maternal motivation decreases with litter age and litter size in farmed mink

   Contributor(s):: Malmkvist, Jens, Sørensen, Dennis D., Larsen, Torben, Palme, Rupert, Hansen, Steffen W.

   The optimal timing of separating the mink dam from the litter is suggested to be a balance between the partly conflicting needs of the mother and the kits. Early removal of the dam or partial removal of the litter may protect the dam against exhaustion. Little is, however, known about dam stress...

3. 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...

4. The effects of social interaction and environmental enrichment on the space use, behaviour and stress of owned housecats facing a novel environment

   Contributor(s):: Rehnberg, L. K., Robert, K. A., Watson, S. J., Peters, R. A.

   Every day, millions of domestic cats are held temporarily in captive environments, such as boarding catteries and rescue shelters. Being in confinement can potentially invoke high levels of stress for these animals. Therefore, there is a need to develop appropriate strategies to reduce these...

5. 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,...

6. Frustrated appetitive foraging behavior, stereotypic pacing, and fecal glucocorticoid levels in snow leopards ( Uncia uncia ) in the Zurich Zoo

   Contributor(s):: Burgener, N., Gusset, M., Schmid, H.

   This study hypothesized that permanently frustrated, appetitive-foraging behavior caused the stereotypic pacing regularly observed in captive carnivores. Using 2 adult female snow leopards (U), solitarily housed in the Zurich Zoo, the study tested this hypothesis experimentally with a novel...

7. Hormonal stress response of laboratory mice to conventional and minimally invasive bleeding techniques

   Contributor(s):: Voigt, C. C., Klockner, P., Touma, C., Neuschl, C., Brockmann, G., Goritz, F., Palme, R., Thomsen, R.

8. Measuring faecal glucocorticoid metabolites as a non-invasive tool for monitoring adrenocortical activity in South American camelids

   Contributor(s):: Arias, N., Requena, M., Palme, R.

9. Can non-invasive glucocorticoid measures be used as reliable indicators of stress in animals?

   Contributor(s):: Lane, J.

10. Environmental enrichment exerts anxiolytic effects in the Indian field mouse ( Mus booduga)

    Contributor(s):: Varman, D. R., Ganapathy, Marimuthu, Rajan, K. E.

11. Monitoring stress hormone metabolites as a useful, non-invasive tool for welfare assessment in farm animals

    Contributor(s):: Palme, R.

12. Influence of housing on weanling horse behaviour and subsequent welfare

    Contributor(s):: Heleski, C. R., Shelle, A. C., Nielsen, B. D., Zanella, A. J.

    Weaning foals marks a stressful event in horses' lives. Limited research exists regarding different housing methods post-weaning and the long-term implications on horse behaviour and welfare. The purpose of this study was to monitor behaviour and physiological stress markers in horses weaned...

13. Neonatal handling of Amazon parrots alters the stress response and immune function

    Contributor(s):: Collette, J. C., Millam, J. R., Klasing, K. C., Wakenell, P. S.

    The influence of neonatal handling on behaviour and immune function was assessed in Orange-winged Amazon parrots (Amazona amazonica). Chicks (n=11) were gently handled daily from 25 days of age until 38 days post-fledging, while control chicks (n=9) were not handled. At 10 days post-fledging...

14. Stress response of working African elephants to transportation and safari adventures

    Contributor(s):: Millspaugh, T. T., Burke, T., Dyk, G. van, Slotow, R., Washburn, B. E., Woods, R. J.

    African elephants (Loxodonta africana) are intensively managed in southern Africa and are routinely translocated between reserves. Domesticated elephants are used for elephant-back safaris and interactions with guests. Understanding how elephants respond to such activities is critical because of...

15. Effect of differential rearing on the behavioral and adrenocortical response of lambs to a novel environment

    Contributor(s):: Moberg, G. P., Wood, V. A.

    When lambs (14 days old) were placed in an open space, those reared in isolation were more withdrawn (were slow to begin moving, vocalized infrequently and avoided new objects) than lambs reared with dams or with other lambs. The difference in response was less pronounced when all lambs were...

16. Effects of chronic stress on some blood parameters in the pig

    Contributor(s):: Barnett, J. L., Hemsworth, P. H., Hand, A. M.

    Plasma samples from juvenile female pigs exhibiting a chronic stress response, evidenced by higher free corticosteroid concentrations, changes in behaviour and reduced growth rates, were analysed for plasma concentrations of total protein, albumin, glucose, urea and cholesterol. Chronic stress...

17. Hormonal influences on conditioned fear in pigs

    Contributor(s):: Dantzer, R., Mormede, P.

18. Effects of enrichment and housing on cortisol response in juvenile rhesus monkeys

    Contributor(s):: Schapiro, S. J., Bloomsmith, M. A., Kessel, A. L., Shively, C. A.

19. Effects of vitamin C supplementation on the adrenocortical and tonic immobility fear reactions of Japanese quail genetically selected for high corticosterone response to stress

    Contributor(s):: Satterlee, D. G., Jones, R. B., Ryder, F. H.

    Japanese quail chicks (18 days of age), from a line genetically selected for high plasma corticosterone response to brief immobilization stress, were treated for 24 h with either untreated drinking water or with a vitamin C (1200 mg/l of ascorbic acid: AA) solution. The chicks were subsequently...
