  1. Modifying the behaviour of singly caged baboons: evaluating the effectiveness of four enrichment techniques

    Contributor(s):: Bourgeois, S. R., Brent, L.

    Techniques to reduce or prevent behavioural disturbances in singly caged primates vary in form and effectiveness, with some behaviours being exceptionally resistant to treatment. Seven singly caged adolescent male olive hybrid baboons (Papio hamadryas anubis) were selected for behavioural...

    Contributor(s):: Ashley, S., Brown, S., Ledford, J., Martin, J., Nash, A. E., Terry, A., Tristan, T., Warwick, C.

    The authors formally investigated a major international wildlife wholesaler and subsequently confiscated more than 26,400 nonhuman animals of 171 species and types. Approximately 80% of the nonhuman animals were identified as grossly sick, injured, or dead, with the remaining in suspected...

  3. Musical Dogs: A Review of the Influence of Auditory Enrichment on Canine Health and Behavior

    Full-text: Available

    | Contributor(s):: Abigail M. Lindig, Paul D. McGreevy, Angela J. Crean

    Music therapy yields many positive health outcomes in humans, but the effects of music on the health and welfare of nonhuman animals vary greatly with the type of music played, the ethology of the species, and the personality and learning history of individual animals. One context in which...

  4. Naturalising diet to reduce stereotypic behaviours in slow lorises rescued from wildlife trade

    | Contributor(s):: Chatpongcharoen, Padcha, Campera, Marco, Laithong, Phadet, Gibson, Nancy L., Nekaris, K. A. I.

  5. Nest provision influences reproductive success in breeding blue fox vixens: a preliminary study

    | Contributor(s):: Pyykonen, T., Ahola, L., Hanninen, S., Mononen, J.

    The aim of the present study was to evaluate the effects of an unfamiliar nest and environmental enrichment, ie provision of an additional nest, on farmed blue fox (Alopex lagopus) vixens' reproductive performance. Two experimental groups were evaluated in the study: (i) a single nest (SN) group...

  6. Note on effects of a daylong feeding enrichment program for Chimpanzees ( Pan troglodytes )

    | Contributor(s):: Morimura, N.

    For captive chimpanzees, daylong feeding enrichment, offering longer feeding times as comparable to those of their wild counterparts, is expected to alleviate undesirable behavior. This study is designed to determine whether longer feeding opportunities over the course of a day would directly...

  7. Novel environmental enrichment may provide a tool for rapid assessment of animal personality: a case study with giant pandas ( Ailuropoda melanoleuca )

    | Contributor(s):: Powell, D. M., Svoke, J. T.

    Historically, the assessment of nonhuman animal personality has included a variety of methods - from direct behavioural observations in a variety of test situations to assessments provided by animal caretakers or trainers. Careful observation of how animals in zoos interact with novel enrichment...

  8. Novelty and individual differences influence neophobia in orange-winged Amazon parrots ( Amazona amazonica )

    | Contributor(s):: Fox, R. A., Millam, J. R.

    Environmental enrichment both improves the welfare of captive animals and increases the validity of research using these animals. Enrichment programs have been shown to prevent or reduce the development of behavioral vices, stereotypy, and fearfulness. However, the protocols used in enrichment...

  9. Olfactory Enrichment in California Sea Lions (Zalophus californianus): An Effective Tool for Captive Welfare?

    | Contributor(s):: Samuelson, Mystera M., Lauderdale, Lisa K., Pulis, Kelly, Solangi, Moby, Hoffland, Tim, Lyn, Heidi

    In the wild, California sea lions (Zalophus californianus) are exposed to a wide variety of sensory information, which cannot be replicated in captive environments. Therefore, unique procedures are necessary for maintaining physiological and psychological health in nonhuman animals in captivity....

  10. On the use of an automated learning device by group-housed dwarf goats: do goats seek cognitive challenges?

    | Contributor(s):: Langbein, J., Siebert, K., Nurnberg, G.

    It has been postulated that implementing appropriate cognitive challenges in the housing of captive animals allows them to use their cognitive skills, and to learn to control certain aspects of their environment. This cognitive activity is thought to be a major source of positive emotions and a...

  11. Operant animal welfare: productive approaches and persistent difficulties

    | Contributor(s):: Patterson-Kane, E. G., Pittman, M., Pajor, E. A.

    Operant procedures occupy a prominent role within animal welfare science because they provide information about the strength of animals' preferences. It is assumed that strongly motivated choices commonly indicate conditions necessary for uncompromised welfare. A review of the literature shows...

  12. Over-sized pellets naturalize foraging time of captive Orange-winged Amazon parrots (Amazona amazonica)

    | Contributor(s):: Rozek, J. C., Danner, L. M., Stucky, P. A., Millam, J. R.

    Parrots held in captivity experience distinctly different environmental demands, as compared to their wild conspecifics, particularly in regard to feeding. Cages equipped with computer-monitored infra-red beams (placed across a primary perch, in front of the feeder, in front of the drinking...

  13. Perceived importance of specific kennel management practices for the provision of canine welfare

    | Contributor(s):: Cobb, M. L., Carter, A., Lill, A., Bennett, P. C.

    There is public interest for the welfare of dogs that spend at least part of their lives housed in kennel facilities, such as working, shelter and sporting dogs. The impacts of living in environments that limit social, physical, and behavioral opportunities are generally well understood in other...

  14. Performance on a categorisation task suggests that removal of environmental enrichment induces 'pessimism' in captive European starlings ( Sturnus vulgaris )

    | Contributor(s):: Bateson, M., Matheson, S. M.

    Improving the quality of life of captive animals is dependent on developing valid measures of how animals feel about their lives. It has recently been suggested that biases in information processing may offer a novel means of understanding animal emotions. Anxious and depressed people tend to...

  15. Periods of early development and the effects of stimulation and social experiences in the canine

    | Contributor(s):: Battaglia, C. L.

    It is not capacity that explains the differences that exist between individuals, because most seem to have far more capacity than they will ever use. The differences that exist between individuals seem to be related to something else. Researchers have studied these phenomena and have looked for...

  16. Pigs with but not without access to pieces of recently harvested wood show reduced pen-mate manipulation after a provision of feed and straw

    | Contributor(s):: Telkanranta, Helena, Valros, Anna

    In barren environments of commercial farms, pig often redirect their rooting and chewing behaviours at other pigs, which can lead to tail biting. When materials such as straw are provided, the quantity is usually too small to have an effect. The aim of this study was to test whether small...

  17. Play and welfare in domestic cats: Current knowledge and future directions

    | Contributor(s):: Henning, J. S. L., Fernandez, E. J., Nielsen, T., Hazel, S.

  18. Plumage damage in free-range laying hens: behavioural characteristics in the rearing period and the effects of environmental enrichment and beak-trimming

    | Contributor(s):: Hartcher, K. M., Tran, M. K. T. N., Wilkinson, S. J., Hemsworth, P. H., Thomson, P. C., Cronin, G. M.

    Severe feather-pecking, whereby birds peck at and pull out the feathers of other birds, is one of the greatest welfare concerns and the most prevalent behavioural problem in laying hens. It can be extremely difficult to control, especially in non-cage laying flocks. Despite a multitude of studies...

  19. Positive reinforcement training as enrichment for singly housed rhesus macaques ( Macaca mulatta )

    | Contributor(s):: Baker, K. C., Bloomsmith, M. A., Neu, K., Griffis, C., Maloney, M.

    Positive reinforcement training is one component of behavioural management employed to improve psychological well-being. There has been regulatory promotion to compensate for restricted social housing in part by providing human interaction to singly caged primates, implying an efficacy standard...

  20. Pre-weaning environmental enrichment increases piglets’ object play behaviour on a large scale commercial pig farm

    | Contributor(s):: Yang, Chung-Hsuan, Ko, Heng-Lun, Salazar, Laura C., Llonch, Lourdes, Manteca, Xavier, Camerlink, Irene, Llonch, Pol

    Environmental enrichment is a legal requirement for European pig farms. The suitability of enrichment materials for neonatal pigs is understudied and has not been tested in commercial settings. This study investigates the effect of hanging objects and substrate as two enrichment strategies...
