We assessed environmental and...

  7. A survey of abnormal repetitive behaviors in North American river otters housed in zoos

    Contributor(s):: Morabito, P., Bashaw, M. J.

    Stereotypic behaviors, indicating poor welfare and studied in a variety of species (especially carnivores), appear related to characteristics of current and past environments. Although North American river otters (Lontra canadensis) often develop abnormal, repetitive, possibly stereotypic...

  8. Aggressive behavior in two different group-housing systems for pregnant sows

    Contributor(s):: Chapinal, N., Ruiz-de-la-Torre, J. L., Cerisuelo, A., Gasa, J., Baucells, M. D., Manteca, X.

    The study housed 120 pregnant sows from Day 29 of pregnancy to 1 week before parturition either in groups of 10 with trickle feeding (TRICKLE) or in groups of 20 with an unprotected electronic sow feeding (FITMIX). The study recorded aggressive interaction on 11 nonconsecutive days. Frequency of...

  9. Current attitudes toward, and incidence of, sterilization of cats and dogs by caregivers (owners) in Auckland, New Zealand

    Contributor(s):: McKay, S. A., Farnworth, M. J., Waran, N. K.

    This study distributed a questionnaire to cat or dog caregivers (owners) throughout Auckland, New Zealand, to investigate the attitudes of human companions toward the sterilization of their cats and dogs and the degree to which this occurs relative to demographic information gathered. A total of...

  10. Effect of breed, cage type, and reproductive phase on fecal corticosterone levels in doe rabbits

    Contributor(s):: Prola, L., Cornale, P., Renna, M., Macchi, E., Perona, G., Mimosi, A.

    Fecal corticosterone concentration (FCC) is increasingly being used as a noninvasive indicator of stress in assessment of nonhuman animal welfare. The aim of this study was to evaluate effects of breed, cage type, reproductive phase, and their interactions on FCC levels in doe rabbits. A total of...

  11. Fecal concentrations of cortisol, testosterone, and progesterone in cotton-top tamarins housed in different zoological parks: relationships among physiological data, environmental conditions, and behavioral patterns

    Contributor(s):: Fontani, S., Vaglio, S., Beghelli, V., Mattioli, M., Bacci, S., Accorsi, P. A.

    The aim of this investigation was to study the welfare of 3 captive groups of cotton-top tamarins housed in different zoological parks. Ethological observations were conducted during 1 year. In addition, fecal samples were collected and the concentrations of glucocorticoids, androgens, and...

  12. If you knew what was good for you! The value of environmental enrichments with known welfare benefits is not demonstrated by sows using operant techniques

    Contributor(s):: Elmore, M. R. P., Garner, J. P., Johnson, A. K., Kirkden, R. D., Richert, B. T., Pajor, E. A.
