  1. 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...

  2. Development of stereotypies and polydipsia in wild caught bank voles ( Clethrionomys glareolus ) and their laboratory-bred offspring. Is polydipsia a symptom of diabetes mellitus?

    Contributor(s):: Schoenecker, B., Heller, K. E., Freimanis, T.

    The development of stereotypies and polydipsia was studied in wild caught bank voles (P: n=92) and their laboratory-bred offspring (F1: n=248). All animals were kept isolated in barren cages in the laboratory. In the P generation, no individuals developed stereotypies, but 22% developed...

  3. Do the stereotypies of pigs, chickens and mink reflect adaptive species differences in the control of foraging?

    Contributor(s):: Mason, G., Mendl, M.

    Species differences in food-related stereotypies and natural foraging behaviour are discussed, and evolutionary explanations for these species differences, and reasons why apparent species differences in stereotypy may be artefacts of husbandry are postulated.

  4. Behavior of picketed circus elephants

    Contributor(s):: Friend, T. H.

    The behaviour of 14 female Asian (Elephas maximus) and 3 female African (Loxodonta africana) elephants who performed 2 shows each day with a circus that travelled to a new location (40 to 250 km from the previous day's lot) daily, was studied. When not performing or working, the elephants were...

  5. The effect of increasing visual horizons on stereotypic weaving: implications for the social housing of stabled horses

    Contributor(s):: Cooper, J. J., McDonald, L., Mills, D. S.

    Stabled horses commonly perform stereotypic patterns of weaving, where the horse shifts its weight from side to side often swinging its head. Ten warm-blood types, of which five were known to reliably weave, were housed in similar 12 x 12 ft wooden loose boxes in a single stable block surrounding...

  6. Stereotypies and attentiveness to novel stimuli: a test in polar bears

    Contributor(s):: Wechsler, B.

    Marks of unfamiliar odours were placed on the stereotyped paths of two captive polar bears in order to test their attentiveness to novel stimuli during stereotyped walking. Both individuals significantly increased their rate of sniffing compared with stereotyped walking bouts without odour marks...

  7. Stereotypies, aggression and the feeding schedules of tethered sows

    Contributor(s):: Rushen, J. P.

    Thirty, adult, pregnant, tethered sows were observed for 5 min every 0.5 h for 9 h spanning the 2 feeding periods. Activity, consisting largely of food-searching behaviour and drinking, was largely restricted to two 2-h periods following each feed. Three categories of stereotyped behaviour were...

  8. Clinical ethology in food animal practice

    Contributor(s):: Luescher, U. A., Friendship, R. M., Lissemore, K. D., McKeown, D. B.

  9. Evaluation of crates and girth tethers for sows: reproductive performance, immunity, behavior and ergonomic measures

    Contributor(s):: McGlone, J. J., Salak-Johnson, J. L., Nicolson, R. I., Hicks, T.

    An evaluation was made for two common sow housing systems: the girth tether and crate. Littermate Yorkshire X Landrace gilts were randomly assigned to either the crate or girth tether system and they remained in that treatment for 2 consecutive pregnancies and lactations. A total of 171 matings...

  10. Effects of group and individual housing on the behavior of kennelled dogs in animal shelters

    Contributor(s):: Mertens, P. A., Unshelm, J.

    To emphasize the effects of group- and single housing of kennelled dogs, the behavior of 211 dogs in two German animal shelters was tested and observed. After being placed, 197 of the dogs' new owners were interviewed.Although 51% of the German animal shelters already keep dogs in groups, there...
