  1. 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...

  2. 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...

  3. 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...

  4. 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....

  5. 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...

  6. 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...

  7. 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.

  8. 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...

  9. 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...

  10. Activity and enrichment use in disabled Asiatic black bears (Ursus thibetanus) rescued from bile farms

    Full-text: Available

    | Contributor(s):: Dallaire, J. A., Field, N., Mason, G. J.

    Physical disability has the potential to impede the use of environmental enrichments in rehabilitation programmes. We therefore compared the behaviour of 63 disabled and non-disabled socially housed adult Asiatic black bears rescued from bile farms for 103 observation hours. Amputees were less...

  11. Alternatives to nose-ringing in outdoor sows: 2. The provision of edible or inedible overground enrichment

    | Contributor(s):: Edge, H. L., Bornett, H. L. I., Newton, E., Edwards, S. A.

    The nose-ringing of outdoor pigs (Sus scrofa), although commonly practiced as a means to inhibit rooting behaviour and therefore reduce pasture damage and soil erosion, has been questioned on ethical grounds and alternatives are being sought. In this experiment, the effect of overground...

  12. An assessment of laboratory mouse welfare in UK animal units

    | Contributor(s):: Leach, M. C., Main, D. C. J.

    The welfare of conventional stock laboratory mice has been assessed in 46 UK animal units using an expert-defined welfare assessment protocol containing 119 measures of mouse welfare. These were recorded using a questionnaire and observations made during a one-day visit to each unit. The standard...

  13. An empirical case study examining effectiveness of environmental enrichment in two captive Australian Sea Lions ( Neophoca cinerea )

    | Contributor(s):: Smith, B. P., Litchfield, C. A.

    This case study examined the effect of environmental enrichment on the activity budgets of a male and female Australian Sea Lion (Neophoca cinerea) housed together at Adelaide Zoo. Using non-food-related (intrinsic) and food-related (extrinsic) enrichment objects, the study conducted an ABABA...

  14. An investigation of the effect of environmental enrichment and space allowance on the behaviour and production of growing pigs

    | Contributor(s):: Beattie, V. E., Walker, N., Sneddon, I. A.

    Newly weaned 6-week-old pigs in groups of 6 littermates were placed in enriched environments with a floor space allowance of 0.5, 1.1, 1.7 or 2.3 msuperscript 2/pig (treatments 1-4, respectively). Treatment 5 was identical to treatment 4, except for the absence of enriching elements which...

  15. Are wild animals suited to a travelling circus life?

    | Contributor(s):: Iossa, G., Soulsbury, C. D., Harris, S.

    A comprehensive synopsis of the welfare of captive, wild (ie non-domesticated) animals in travelling circuses is missing. We examined circus animal welfare and, specifically, behaviour, health, living and travelling conditions. We compared the conditions of non-domesticated animals in circuses...

  16. Auditory stimulation as enrichment for zoo-housed Asian elephants ( Elephas maximus )

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

    This study explored the effect of auditory stimulation on the behaviour and welfare of four zoo-housed, female Asian elephants (Elephas maximus). All animals were exposed, in an ABA design, to two conditions of auditory stimulation: a 'control' (no auditory stimulation), and an 'experimental'...

  17. Behavioral responses of silverback gorillas ( Gorilla gorilla gorilla ) to videos

    | Contributor(s):: Maloney, M. A., Leighty, K. A., Kuhar, C. W., Bettinger, T. L.

    This study examined the impact of video presentations on the behavior of 4 silverback, western lowland gorillas (Gorilla gorilla gorilla). On each of 5 occasions, gorillas viewed 6 types of videos (blue screen, humans, an all-male or mixed-sex group engaged in low activity, and an all-male or...

  18. Behaviour and performance of pigs finished on deep bedding with wood shavings or rice husks in summer

    | Contributor(s):: Hotzel, M. J., Lopes, E. J. C., Oliveira, P. A. V. de, Guidoni, A. L.

    Concern that excessive temperatures arising from substrate fermentation could have a deleterious effect on voluntary feed intake and weight gain, especially during the hottest times of the year, might be a barrier to the widespread adoption of deep-bedding systems for pig production in Brazil....

  19. Behaviour of golden hamsters ( Mesocricetus auratus ) kept in four different cage sizes

    | Contributor(s):: Fischer, K., Gebhardt-Henrich, S. G., Steiger, A.

    Cages for laboratory and pet hamsters are usually small. Using video recordings, the behaviour of sixty female golden hamsters (Mesocricetus auratus), housed individually in four different cage sizes, was compared in order to draw conclusions about their welfare. The cage sizes were 1,800 cm2,...

  20. Behavioural effects of environmental enrichment for individually caged rabbits

    | Contributor(s):: Lidfors, L.

    The behavioural effects of providing 60 male New Zealand laboratory rabbits with one of four objects in their individual cages as environmental enrichment were investigated. The rabbits were assigned to one of 5 treatments by a random procedure; hay in a water bottle, grass-cubes, two gnawing...
