  1. Effects of Sheltering on Behavior and Fecal Corticosterone Level of Elderly Dogs

    Contributor(s):: Katsuji Uetake, Chu Han Yang, Aki Endo, Toshio Tanaka

    In Japan, the human population is aging rapidly, and the abandonment of dogs by the elderly people who have died or been hospitalized becomes a problem. It is hypothesized that elderly dogs have difficulty adapting to the novel circumstances when brought to an animal shelter. Therefore, the...

  2. Pit Bulls Today

    Contributor(s):: Hannah Nation

    The motivation for this research paper is to shed a new light on the drastic effects negative stereotypes have on breeds that are deemed aggressive in the media and public’s eye. It’s important to understand the full scope of the situation in our society and the consequences that come...

  3. The Perception of Men and Women and the Pets They Own: Female Necessarily Equal Feline?

    Contributor(s):: Santina D. Masters, Steve Colletes

    While much research had investigated factors that influence the decisions io own pets, little is known about perceptions of people who own pets. In an examination of the perceptlons of people who own animals that do not fit the gender stereotype for pet ownership, 134 volunteers from a local...

  4. Association between increased behavioral persistence and sterotypy in the pet dog

    Contributor(s):: Alexandra Protopopova, Nathaniel Hall, Clive Wynne

  5. 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...

  6. Social attachment in giraffe: response to social separation

    Contributor(s):: Tarou, L. R., Bashaw, M. J., Maple, T. L.

    Attachment relationships between animals are often studied by separating a pair of individuals and recording their subsequent behaviour. Studies of non-human primates have shown that separation results in changes that are indicative of both psychological and physiological stress. Similar results...

  7. 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...

  8. 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.

  9. Does the number of daily meals affect feeding motivation and behaviour of gilts fed high-fibre diets?

    Contributor(s):: Robert, S., Bergeron, R., Farmer, C., Meunier-Salaun, M. C.

    The feeding motivation and feeding-related stereotypies of pregnant gilts fed high-fibre (HF) or concentrate (C) diets in one or two daily meals were compared. 24 gilts were fed either a concentrate or high-fibre diet with the same daily intake of energy and major nutrients. The effect of the...

  10. Stereotypic behaviour is genetically transmitted in the African striped mouse Rhabdomys pumilio

    Contributor(s):: Schwaibold, U., Pillay, N.

    The development of stereotypic behaviour was studied in captive striped mice, Rhabdomys pumilio. Based on the findings of previous studies, it was hypothesized that there is a genetic basis of stereotypy in striped mice. Breeding and cross-fostering experiments were used to test this hypothesis....

  11. 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...

  12. Phenotyping stereotypic behaviour: collective variables, range of variation and predictability

    Contributor(s):: Golani, I., Kafkafi, N., Drai, D.

  13. 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...

  14. The effect of penning versus picketing on stereotypic behavior of circus elephants

    Contributor(s):: Friend, T. H., Parker, M. L.

    The behaviour of 9 female Asian elephants (Elephas maximus) who performed 2 shows each day with a circus that travelled to a new location in the USA (40 to 250 km from the previous day's lot) daily or every 2 days was studied during the 1996 and 1998 seasons. When not performing or working, the...

  15. De-arousal properties of stereotyped behaviour: evidence from pituitary-adrenal correlates in pigs

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

    Behavioural and pituitary--adrenal responses of food-deprived pigs, submitted to an intermittent food delivery schedule repeated over several weeks, were investigated. All animals reliably displayed stereotyped activites, in the form of repeated chain pulling, during the interval between food...

  16. Anticipatory behaviour and stereotypical behaviour in farmed mink ( Mustela vison ) in the presence, absence and after the removal of swimming water

    Contributor(s):: Vinke, C. M., Houx, B. B., Bos, R. van den, Spruijt, B. M.

    Captive animals are often provided with cage enrichments in order to improve their welfare. Swimming water is an often-discussed requirement for farmed mink. The present study aimed to give insight into the value of swimming water for farmed mink by measuring anticipatory and stereotypical...

  17. 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...

  18. 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...

  19. 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...

  20. Diurnal rhythm of bar-biting in relation to other behaviour in pregnant sows

    Contributor(s):: Jensen, P.

    Instantaneous observations of behaviour were made with video once every sixth minute around the clock (in 20-s recordings at each interval) during the first 3 days following the introduction of pregnant sows into one of the following three environments: (1)loose housing in groups of five with a...
