  1. The effect of familiarity on behaviour of kennel housed dogs during interactions with humans

    Contributor(s):: Pullen, Anne J., Merrill, Ralph J. N., Bradshaw, John W. S.

    Human contact appears to be a highly valued resource for domestic dogs but it is unclear what type of human contact they prefer and what factors affect individual differences in such preferences. This study assessed the effect of familiarity of the human on duration of interaction by two samples...

  2. The effect of feeding enrichment in the milk-feeding stage on the cognition of dairy calves in a T-maze

    Contributor(s):: Horvath, Kelsey, Fernandez, Mariana, Miller-Cushon, Emily K.

    In many species, environmental complexity is known to affect cognitive development, yet it is common to house dairy calves individually in restrictive environments. The hypothesis of this study was that providing calves with simple nutritional enrichments would improve their success in a...

  3. The effect of feeding enrichment on the moloch gibbon ( Hylobates moloch )

    Contributor(s):: Wells, D. L., Irwin, R. M.

    This study explored the effect of 3 feeding devices (food-filled baskets, polyvinyl chloride tubes, frozen ice pops) on the behavior of 4 zoo-housed moloch gibbons. The project studied the gibbons for 5 days during a control condition (no feeding enrichment) and 5 days per condition of feeding...

  4. The effect of feeding enrichment toys on the behaviour of kennelled dogs (Canis familiaris)

    | Contributor(s):: Schipper, L. L., Vinke, C. M., Schilder, M. B. H., Spruijt, B. M.

    In general, an animal's inability to perform specific behaviours (for example, due to a lack of suitable stimuli or physical restraint) is often viewed as a cause of reduced welfare of animals kept in captivity. There is increasing evidence that the opportunity to display more...

  5. The effect of group size on the behaviour and welfare of four fish species commonly kept in home aquaria

    | Contributor(s):: Saxby, A., Adams, L., Snellgrove, D., Wilson, R. W., Sloman, K. A.

    Previous research into fish welfare has focussed particularly on commercially important aquaculture species. However, with over 350 million fishes traded annually within the ornamental fish industry, surprisingly little consideration has been given to the welfare of fish kept in home aquaria....

  6. The effect of hiding enrichment on stress levels and behaviour of domestic cats ( Felis sylvestris catus ) in a shelter setting and the implications for adoption potential

    | Contributor(s):: Kry, K., Casey, R.

    This study investigates the effect of hiding enrichment on stress and behaviour of kennelled cats. Forty-three cats were studied either with a BC SPCA Hide & PerchTM box as enrichment, or with an open bed as control. Observations consisted of Stress Score, approach test and scan sample, recorded...

  7. The effect of housing and handling practices on the welfare, behaviour and selection of domestic cats (Felis sylvestris catus) by adopters in an animal shelter

    | Contributor(s):: Gourkow, N., Fraser, D.

  8. The effect of human interaction on guinea pig behavior in animal-assisted therapy

    Full-text: Available

    | Contributor(s):: Winnie Gut, Lisa Crump, Jakob Zinsstag, Jan Hattendorf, Karin Hediger

    Guinea pigs are included in various animal-assisted interventions (AAIs), but no research has been published to date on behavioral changes in guinea pigs interacting with humans. The goal of this study was to evaluate the behavior in guinea pigs during animal-assisted therapy (AAT) and to...

  9. The effect of pen size and an enrichment structure (elevated platform) on the performances and the behaviour of fattening rabbits

    | Contributor(s):: Postollec, G., Boilletot, E., Maurice, R., Michel, V.

    The effects of a (30 cm high) elevated platform as an enrichment structure on the behaviour and performance of fattening rabbits kept in groups were investigated. Three housing systems for fattening rabbits were compared using a stocking density of 15 rabbits m-2. The rabbits were housed either...

  10. The effect of rope color, size and fray on environmental enrichment device interaction in male and female Orange-winged Amazon parrots ( Amazona amazonica )

    | Contributor(s):: Webb, N. V., Famula, T. R., Millam, J. R.

    Environmental enrichment devices (EDs; a.k.a. cage "toys") are often provided to captive parrots to mitigate the austerity of their environments, but the basis of attraction to EDs by parrots is poorly understood and many EDs go un-used. Preferences of Orange-winged Amazon parrots...

  11. The effect of the functional attributes of objects within the caged environment on interaction time in laboratory rats

    | Contributor(s):: Williams, C. M., Hanmer, L. A., Riddell, P. M.

    Determining rat preferences for, and behaviour towards, environmental enrichment objects allows us to provide evidence-based information about how the caged environment may be enriched. In recent years there have been many studies investigating the preferences of laboratory rodents for a wide...

  12. The effect of the kennel environment on canine welfare: a critical review of experimental studies

    | Contributor(s):: Taylor, K. D., Mills, D. S.

    Dogs can be held temporarily or permanently in kennels for a number of reasons, not necessarily for their own benefit. Although restrictive environments have been associated with poor welfare, priorities for research and change cannot be understood unless the various aspects of the kennel...

  13. The effect of three different items of cage furniture on the behaviour of male C57BL/6J mice in the plus-maze test

    | Contributor(s):: Okva, K., Nevalainen, T., Mauranen, K., Pokk, P.

    The aim of this study was to assess the effects of specific regimens of enrichment on the behaviour of C57BL/6J mice in the elevated plus-maze test (EPM). A total of 192 male C57BL/6J mice were allocated randomly to 32 cages. Three different items of cage furniture (CF) made of aspen - a mouse...

  14. The effect of type of rooting material and space allowance on exploration and abnormal behaviour in growing pigs

    | Contributor(s):: Jensen, M. B., Studnitz, M., Pedersen, L. J.

    The experiment aimed to investigate the effect of type of rooting material and space allowance on explorative and abnormal behaviour in growing pigs. Thirty-six pens with partly slatted concrete floor were allocated to one of four treatments: (1) low space allowance and maize silage as rooting...

  15. The effect of varying lengths of straw bedding on the behaviour of growing pigs

    | Contributor(s):: Day, J. E. L., Weerd, H. A. van de, Edwards, S. A.

    Straw provided as a substrate allows pigs to use it as a recreational substrate, as a nutritional substrate and as a bedding material and, because of this, has been reported to improve the welfare of pigs. The aim of this study was to investigate whether different lengths of chopped straw bedding...

  16. The Effectiveness Of Enrichment Programs For Dogs In An Animal Shelter

    | Contributor(s):: Pamela Perry

    Dogs (N = 108) in an animal shelter received one of four enrichment programs: twice daily walking alone (walking) or in combination with a daily fooddispensing toy (toy), a daily session of standardized human contact (petting), or daily obedience training (obedience). We evaluated the effects of...

  17. The effectiveness of environmental enrichment on reducing stereotypic behaviour in two captive vicugna ( Vicugna vicugna )

    | Contributor(s):: Parker, M., Goodwin, D., Redhead, E., Mitchell, H.

    Environmental enrichment by increasing foraging behaviour and providing food item choice are widely practised and generally accepted as effective methods for reducing stereotypic behaviour in captive animals. In this study, the effectiveness of increasing foraging patch choice and food item...

  18. The effects of automated scatter feeders on captive grizzly bear activity budgets

    | Contributor(s):: Andrews, N. L. P., Ha, J. C.

    Although captive bears are popular zoo attractions, they are known to exhibit high levels of repetitive behaviors (RBs). These behaviors have also made them particularly popular subjects for welfare research. To date, most research on ursid welfare has focused on various feeding methods that seek...

  19. The effects of different types of feeding enhancements on the behaviour of single-caged, yearling rhesus macaques

    | Contributor(s):: Schapiro, S. J., Suarez, S. A., Porter, L. M., Bloomsmith, M. A.

    Captive primates rarely spend as much time searching for, obtaining and processing feed as do their wild counterparts. Enrichment techniques designed to encourage captive primates to spend more species-appropriate amounts of time in foraging behaviour have been successful. Behavioural effects of...

  20. The effects of education programmes on Atlantic bottlenose dolphin ( Tursiops truncatus ) behaviour

    | Contributor(s):: Miller, L. J., Mellen, J., Greer, T., Kuczaj, S. A., II

    Atlantic bottlenose dolphins (Tursiops truncatus) are found in zoos and aquaria throughout the world. As the number of facilities with dolphin shows and interaction programmes increases, it becomes more important to understand the effects of such programmes on dolphin behaviour. The present study...
