  1. An examination of some physiological variables for assessing the welfare of beef cattle in feedlots

    Contributor(s):: Wilson, S. C., Fell, L. R., Colditz, I. G., Collins, D. P.

    Some physiological variables which could aid in assessing the welfare of beef cattle in feedlots were screened in this exploratory study. In two experiments, each of 42 days duration, the physiological responses of Bos taurus steers to three treatments were investigated: pasture (rotation between...

  2. An investigation of the relationship between adrenal activity, social rank and immunocompetence in pregnant sows kept in different housing conditions

    Contributor(s):: Zanella, A. J., Mendl, M. T., Broom, D. M.

  3. Associations of behaviour with secretory immunoglobulin A and cortisol in domestic cats during their first week in an animal shelter

    Contributor(s):: Gourkow, N., LaVoy, A., Dean, G. A., Phillips, C. J. C.

    We tested the hypothesis that during their first week in an animal shelter, cats exhibit groups of behaviours that are connected to mucosal immune and adrenal responses. The behaviour of 34 cats was observed from admission to day 5 and immunoglobulin A (S-IgA) and cortisol were quantified from...

  4. Behavioral reactions relate to adrenal activity and temperament in male clouded leopards ( Neofelis nebulosa)

    Contributor(s):: DeCaluwe, H. B., Wielebnowski, N. C., Howard, J., Pelican, K. M., Ottinger, M. A.

    Due to strong intra-specific aggression and frequent adverse reactions to changes encountered in the captive setting, clouded leopards ( Neofelis nebulosa) are particularly difficult to manage as a self-sustaining population in zoos. The aim of this study was to examine the efficacy of behavioral...

  5. Behaviour and adrenal activity of first parturition and multiparous cows under a competitive situation

    Contributor(s):: Gonzalez, M., Yabuta, A. K., Galindo, F.

    First parturition cows have to cope with several changes in their environment that can compromise their welfare and health. In addition to being separated from their calves they have to compete for eating and lying places with older and more experienced cows once they are introduced to the...

  6. Behaviour, wounds, weight loss and adrenal weight of rabbit does as affected by semi-group housing

    Contributor(s):: Buijs, S., Maertens, L., Hermans, K., Vangeyte, J., Tuyttens, F. A. M.

    Group housing is often assumed to improve the welfare of gregarious species. Whether this is actually the case depends on the advantages (e.g. more opportunity for social and locomotor behaviour) and disadvantages (e.g. increased fighting and wounding) induced by the specific housing type. We...

  7. Behavioural and hormonal indicators of enduring environmental stress in dogs

    Contributor(s):: Beerda, B., Schilder, M. B. H., Hooff, J. A. R. A. M. van, Vries, H. W. de, Mol, J. A.

    Selected behavioural and hormonal parameters were compared in a group of privately owned dogs with relatively low chronic stress (group 1) with 3 groups of dogs (groups 2, 3 and 4) that were kept under conditions of low to relatively high austerity, and had basal urinary ratios of cortisol to...

  8. Behavioural reaction of individual pigs raised in different environments to a novel object and to handling at slaughter in relation to measurements of the adrenal cortex

    Contributor(s):: Rasmussen, A. A.

  9. Behavioural responses of heifers to ACTH injections

    Contributor(s):: Negrao, J. A., Porcionato, M. A. de F., Passille, A. M. de, Rushen, J.

    The objective of this study was to investigate behavioural changes in Holstein heifers caused by exogenous adrenocorticotropic hormone (ACTH) administration. Twelve 11-month-old heifers were submitted to either a single saline or ACTH injection and then the treatments were switched after 3 days...

  10. Blood catecholamines in response to handling in normal and stress-susceptible swine

    Contributor(s):: DeRoth, L., Vermette, L., Blouin, A., Lariviere, N.

    Venous blood was collected from 23 porcine stress syndrome (PSS)-susceptible and 55 resistant 3-month-old Landrace pigs. Susceptibility to PSS was determined by the halothane test and resistance was confirmed by the halothane succinylcholine test, which were performed after the blood sampling...

  11. Can sleep behaviour be used as an indicator of stress in group-housed rats ( Rattus norvegicus )?

    Contributor(s):: Abou-Ismail, U. A., Burman, O. H. P., Nicol, C. J., Mendl, M.

    We assessed the value of sleep behaviour as a novel measure of stress in group-housed animals. We observed, non-invasively, sleep behaviour in 144 group-housed rats, and related it to other physiological and physical indicators of stress and welfare. Sleep frequency and duration correlated...

  12. Consequences of weaning piglets at 21 and 28 days on growth, behaviour and hormonal responses

    Contributor(s):: Colson, V., Orgeur, P., Foury, A., Mormede, P.

    A recent European Directive raised the minimum weaning age of piglets to 28 days, although weaning at 21 days is still allowed (but not necessarily practiced) in batch breeding conditions. The aim of the present study was to determine the consequences of weaning at 3 and 4 weeks on animal weight...

  13. Effects of family housing on some behavioural and physiological parameters of juvenile farmed mink ( Mustela vison )

    Contributor(s):: Hanninen, S., Mononen, J., Harjunpaa, S., Pyykonen, T., Sepponen, J., Ahola, L.

    Farmed mink are traditionally weaned at the age of 6-8 weeks and the kits live in male-female pairs until pelting time (approximately 6 months of age). It is possible that keeping an entire litter together with the dam in a row-cage system until pelting could provide the juvenile mink with some...

  14. Effects of floor-feeding and the presence of a foraging substrate on the behaviour and stress physiological response of individually housed gilts

    Contributor(s):: Leeuw, J. A. de, Ekkel, E. D., Jongbloed, A. W., Verstegen, M. W. A.

    Both restricted feeding and barren housing have a negative influence on sow welfare. The aim of this study was to test whether sows that have to search for their feed in a substrate on the floor show less stereotyped (and other abnormal) behaviour and have a lower physiological stress response....

  15. Effects of floor-feeding and the presence of a foraging substrate on the behaviour and stress physiological response of individually housed gilts

    Contributor(s):: Leeuw, J. A. de, Ekkel, E. D., Jongbloed, A. W., Verstegen, M. W. A.

    Both restricted feeding and barren housing have a negative influence on sow welfare. The aim of this study was to test whether sows that have to search for their feed in a substrate on the floor show less stereotyped (and other abnormal) behaviour and have a lower physiological stress response....

  16. Effects of freeze or hot-iron branding of Angus calves on some physiological and behavioural indicators of stress

    Contributor(s):: Lay, D. C., Friend, T. H., Grissom, K. K., Bowers, C. L., Mal, M. E.

    Twenty-four Angus calves averaging 293 +or- 38 kg either hot-iron branded (H), freeze branded (F), or served as a sham (S). Calves were grouped for temperament, weight, and sex, and randomly assigned to day and order in which treatments were applied. To reduce stress from handling at treatment...

  17. Effects of prenatal handling stress on adrenal weight and function and behaviour in novel situations in blue fox cubs ( Alopex lagopus )

    Contributor(s):: Braastad, B. O., Osadchuk, L. V., Lund, G., Bakken, M.

    This study investigated the effects of a 1-min daily handling stress given to farmed blue fox females in the last third of gestation on adrenal weight and function in male and female offspring and on behaviour in novel situations. In 10-day-old cubs (n=68), records were made of serum...

  18. Effects of varying feed provision on behavioral patterns of farmed collared peccary (Mammalia, Tayassuidae)

    Contributor(s):: Nogueira, S. S. C., Calazans, S. G., Costa, T. S. O., Peregrino, H., Nogueira-Filho, S. L. G.

    Feeding enrichment regime has been widely employed as an important tool to mimic foraging behavior and improve farm animals' welfare. Some authors have argued that creating some level of uncertainty in the animals' environment is beneficial. Therefore, we evaluated the effects of challenge...

  19. Effects of weaning age on the behavioural and neuroendocrine development of piglets. (Special Issue: Early Weaning.)

    Contributor(s):: Jarvis, S., Moinard, C., Robson, S. K., Sumner, B. E. H., Douglas, A. J., Seckl, J. R., Russell, J. A., Lawrence, A. B.

    Adverse early life experiences can permanently "programme" increases in stress reactivity in adulthood. We investigated whether weaning, which involves maternal separation, at different ages, altered subsequent behaviour, physiology and neuroendocrine function in young pigs. The litters of twelve...

  20. Evaluation of the effects of a socialization program in a prison on behavior and pituitary-adrenal hormone levels of shelter dogs

    Contributor(s):: Hennessy, M. B., Morris, A., Linden, F.

    This study examined outcomes of an ongoing socialization program for shelter dogs conducted at a local prison. Dogs residing at a Humane Society facility were assigned to either a "Control" or "Socialization" treatment. Dogs assigned to both treatments were administered a pretest at the Humane...
