  1. 'All ears': a questionnaire of 1516 owner perceptions of the mental abilities of pet rabbits, subsequent resource provision, and the effect on welfare

    Contributor(s):: McMahon, S. A., Wigham, E.

  2. A meta-analysis of the combined effect of housing and environmental enrichment characteristics on the behaviour and performance of pigs

    Contributor(s):: Averos, X., Brossard, L., Dourmad, J. Y., Greef, K. H. de, Edge, H. L., Edwards, S. A., Meunier-Salaun, M. C.

    To quantify the combined effect of housing conditions and environmental enrichment on the behaviour and performance of pigs, a meta-analysis was performed using information from 45 experiments in 42 published manuscripts. Multiple regression models were applied to evaluate the effects of space...

  3. A meta-analysis on the effects of the housing environment on the behaviour, mortality, and performance of growing rabbits

    Contributor(s):: Sommerville, R., Ruiz, R., Averos, X.

  4. A note on enrichment for captive lion-tailed macaques ( Macaca silenus )

    Contributor(s):: Mallapur, A., Waran, N., Anindya, Sinha

    Two enrichment techniques were devised with the aim of reducing stress and improving welfare for captive lion-tailed macaques in an Indian zoo. In Study A, a log, cotton ropes and a feeding basket were added to the enclosures in different combinations to provide structural and feeding enrichment...

  5. A note on enrichment for spontaneous tool use by chimpanzees ( Pan troglodytes )

    Contributor(s):: Morimura, N.

    In the wild, decisions as to "when", "where", and "how" an animal acts are made based on the individual's own choice; in contrast, the behaviour of wild animals in captivity may be under human control. To improve the physical and psychological well-being of captive animals, we should ensure that...

  6. A note on indoor and outdoor housing preferences of common marmosets ( Callithrix jacchus )

    Contributor(s):: Pines, M. K., Kaplan, G., Rogers, L. J.

    This study examined the preferences of six pairs of common marmosets (Callithrix jacchus) from the colony at the University of New England, Australia, between their home cage and either a large, enriched, indoor room or a smaller outdoor cage. When given free access to move between their home...

  7. A note on the effect of olfactory stimulation on the behaviour and welfare of zoo-housed gorillas

    | Contributor(s):: Wells, D. L., Hepper, P. G., Coleman, D., Challis, M. G.

    Olfactory stimulation has been shown to influence the behaviour of a wide variety of species and is now considered a useful form of environmental enrichment for many captive animals. To date, the effect of odour introduction on the behaviour of primates has been subject to little attention....

  8. A persistent abnormal repetitive behaviour in a false water cobra (Hydrodynastes gigas)

    | Contributor(s):: Michaels, C. J., Gini, B. F., Clifforde, L.

  9. A pilot investigation of possible positive system descriptors in finishing pigs

    | Contributor(s):: Mullan, S., Edwards, S. A., Butterworth, A., Whay, H. R., Main, D. C. J.

    In this study, pig producers were identified whose practices exceeded the basic legal requirements and government recommendations for pig welfare. This novel approach was part of a larger project investigating the feasibility and benefits of the inclusion of some animalbased welfare outcome...

  10. A review of current indicators of welfare in captive elephants (Loxodonta africana and Elephas maximus)

    | Contributor(s):: Williams, E., Chadwick, C. L., Yon, L., Asher, L.

  11. A review of environmental enrichment for kennelled dogs, Canis familiaris

    | Contributor(s):: Wells, D. L.

    Domestic dogs can be housed in a variety of confined conditions, including kennels, shelters and laboratories. Concern over the well-being of dogs housed in human care has prompted much research in recent years into the enrichment of environments for kennelled dogs. This paper highlights the...

  12. A review of environmental enrichment for pigs housed in intensive housing systems

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

    This paper critically reviews the literature concerning environmental enrichment for weaner, grower and finisher pigs housed in intensive (indoor) production systems. The thesis of our review is that successful enrichment should meet four criteria of success: (1) it should increase...

  13. A survey of elephant husbandry and foot health in North American zoos.

    | Contributor(s):: Lewis, K. D., Shepherdson, D. J., Owens, T. M., Keele, M.

    The foot health of elephants in human care is a longstanding concern. In 2001, the AZA Standards for Elephant Management and Care were published recommending husbandry to improve foot health. This article reports the results of a 2006 survey: basic statistics describing facility, husbandry, and...

  14. A survey of the attitudes of stakeholders in the zoo industry towards the husbandry requirements of captive Great Apes

    | Contributor(s):: Fernie, A. C., Tribe, A., Murray, P. J., Lisle, A., Phillips, C. J. C.

  15. A systematic approach towards developing environmental enrichment for pigs

    | Contributor(s):: Weerd, H. A. van de, Docking, C. M., Day, J. E. L., Avery, P. J., Edwards, S. A.

    Environmental enrichment is often implemented without considering the requirements of the animals within their environment and without specifying desired functional behaviours. An approach towards the development of species-specific environmental enrichment for pigs is presented here, which...

  16. A tail of two monkeys: social housing for nonhuman primates in the research laboratory setting

    | Contributor(s):: Seelig, D.

    Despite great adaptability, most nonhuman primates require regular tactile contact with conspecifics for their psychological well being. By illustrating the inherent value of social contact and by providing clues to the best ways of satisfying this need, behavioral studies are useful in designing...

  17. A targeted approach to developing environmental enrichment for two strains of laboratory mice

    | Contributor(s):: Nicol, C. J., Brocklebank, S., Mendl, M., Sherwin, C. M.

    Previous studies on environmental enrichment have generally placed a purported enrichment in the cage and observed changes in behavioural and physiological indicators of welfare. However, many of these 'enrichments' are not purposely designed, or appear to be designed with anthropomorphic...

  18. A zoo animal's neighbourhood: how conspecific neighbours impact welfare

    | Contributor(s):: Whitham, J. C., Miller, L. J.

  19. Abnormal behavior in caged birds kept as pets

    | Contributor(s):: Hoek, C. S. van, Cate, C. ten

    There are a limited number of studies dealing with abnormal behavior in caged birds kept as pets. However, these studies demonstrate the presence of abnormal behavior in both songbirds and parrots. Ethological studies on these birds, as well as studies on domestic and zoo birds, indicate that...

  20. Access to chewable materials during lactation affects sow behaviour and interaction with piglets

    | Contributor(s):: Swan, Kirsi-Marja, Telkänranta, Helena, Munsterhjelm, Camilla, Peltoniemi, Olli, Valros, Anna
