  1. 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...

  2. Some preliminary evidence of the social facilitation of mounting behavior in a juvenile bull Asian elephant ( Elephas maximus )

    Contributor(s):: Rees, P. A.

    This study recorded sexual behaviour within a captive herd of 8 Asian elephants in England, UK, for approximately 230 h on 50 days over a period of 10 months (January-November 1999). A single adult and a single juvenile bull mounting cows more than 160 times were observed. When the juvenile bull...

  3. 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...

  4. Training large macaws for artificial insemination procedures

    Contributor(s):: Leblanc, F., Pothet, G., Jalme, M. S., Dorval, M., Bovet, D.

    For some endangered parrot species, captive breeding may be the only insurance for their survival. However, many individuals in captivity do not reproduce. Artificial insemination (AI) may help overcome reproductive failures or geographic distance. For semen collection in birds, massage is the...

  5. Using fecal hormonal and behavioral analyses to evaluate the introduction of two sable antelope at Lincoln Park Zoo

    Contributor(s):: Loeding, E., Thomas, J., Bernier, D., Santymire, R.

    Introductions of sable antelope (Hippotragus niger) can be difficult due to the potential ensuing aggression compounded by their large horns. The goal was to use hormonal assays and behavioral analyses to evaluate the success of an introduction of 2 adult females at Lincoln Park Zoo. The...

  6. 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.

    This study assessed the motivation of gestating sows housed in standard, barren gestation stalls (used for breeding/implantation and/or gestation) for access to environmental enrichment. Enrichment consisted of a cotton rope or rubber mat in comparison to positive (additional food when fed at...

  7. Physiological responses in wild broodstocks of the Caspian Kutum (Rutilus frisii kutum) subjected to transportation stress

    Contributor(s):: Nikoo, M., Falahatkar, B.

  8. 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...

  9. The welfare and productivity of dry sows in different group housing systems in New Zealand

    Contributor(s):: Chidgey, K. L., Morel, P. C. H., Barugh, I. W.

    This research aimed to evaluate sow welfare and identify potential welfare compromise in specific group housing systems for sows in New Zealand. The relationship between overall welfare outcome on-farm and sow productivity was also investigated. Twenty commercial farms were chosen to represent...

  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. Socialization of a single hand-reared tiger cub

    Contributor(s):: Kelling, A. S., Bashaw, M. J., Bloomsmith, M. A., Maple, T. L.

    Given the drawbacks of hand-rearing nonhuman animals in captivity, the practice is generally avoided, but it is sometimes necessary. A few scientific publications are available to guide managers toward best practices in hand-rearing, but the majority of articles focus on hand-rearing captive...

  12. 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...

  13. Effects of stocking rate on measures of efficacy and welfare during carbon dioxide gas euthanasia of young pigs

    Contributor(s):: Fiedler, K. J., Parsons, R. L., Sadler, L. J., Millman, S. T.

    The objective of this study was to evaluate the effects of chamber stocking rate on facets of animal welfare and efficacy during gas euthanasia of young pigs ( Sus scrofa domesticus). Crossbred pigs (390 neonatal and 270 weaned) designated for euthanasia at production farms were randomly assigned...

  14. Effect of gestation management system on gilt and piglet performance

    Contributor(s):: Muns, R., Manzanilla, E. G., Manteca, X., Gasa, J.

    Individual gestation housing of pregnant sows in stalls from four weeks after mating is banned in the EU. Two experiments were conducted to study the effect of two gestation management and housing systems (STALL: gilts housed in stalls and PEN: gilts loose-housed in pens with increased feed...

  15. Why do people laugh during dog-human play interactions?

    Contributor(s):: Mitchell, R., Sinkhorn, K.

    Given that human laughter has been posited to signal playfulness to dogs, nonserious social incongruity, and positive affect, laughter should occur during incongruous contexts in an affectively positive, nonserious social activity such as dog-human play. A total of 116 laughs in relation to dogs...

  16. Effect of housing and husbandry practices on adrenocortical activity in captive Canada lynx ( Lynx canadensis)
