    A comprehensive study on the behavioral effects of feeding enrichment was conducted on six African elephants housed at the North Carolina Zoological Park in Asheboro, NC. The herd is comprised of are two adult males, three adult females, and one subadult female. The study was conducted over a...

  4. The challenge of challenge: can problem solving opportunities enhance animal welfare? (Special Issue: Conservation, enrichment and animal behavior.)

    | Contributor(s):: Meehan, C. L., Mench, J. A.

    Cognitive mechanisms are an important part of the organization of the behavior systems of animals. In the wild, animals regularly face problems that they must overcome in order to survive and thrive. Solving such problems often requires animals to process, store, retrieve, and act upon...

  5. The development of a novel form of mouse cage enrichment

    | Contributor(s):: Leach, M. C., Ambrose, N., Bowell, V. J., Morton, D. B.

    This article describes the design and testing of a novel form of mouse cage enrichment. A cage insert was designed and developed to fulfill a number of enrichment goals pertaining to its effectiveness and practicality (i.e., to improve the environment of mice in laboratories while causing the...

  6. The differential effects of four types of environmental enrichment on the activity budgets, fearfulness, and social proximity preference of Japanese quail

    | Contributor(s):: Miller, K. A., Mench, J. A.

  7. The effect of a fixed or free toy on the growth rate and aggressive behaviour of weaned pigs and the influence of hierarchy on initial investigation of the toys

    | Contributor(s):: Blackshaw, J. K., Thomas, F. J., Lee, J.

    Thirty two groups (12 pigs per group; 14 groups all female, 16 groups all male, 2 groups mixed) of 4- to 5-week old Large WhitexLandracexDuroc weaners were randomly assigned to 1 of 4 treatments (eight groups per treatment): (1) control group with no toys; (2) fixed toy only, hanging from the...

  8. The effect of a new vertical structure in mitigating aggressive behaviour in a large group of chimpanzees ( Pan troglodytes )

    | Contributor(s):: Caws, C. E., Wehnelt, S., Aureli, F.

    The availability and complexity of escape routes are key aspects in modulating aggression. The effect of increased vertical space on the occurrence and severity of aggression was studied in a large group of chimpanzees (Pan troglodytes). Fifty wooden poles were added to the outdoor enclosure at...

  9. The effect of a randomised enrichment treatment schedule on the behaviour of cheetahs (Acinonyx jubatus)

    | Contributor(s):: Quirke, Thomas, O’Riordan, Ruth M.

    A range of types of enrichment have been shown to enhance activity levels, reduce stereotypical behaviours and increase levels of natural behaviour, subsequently improving the welfare of many species of captive animals. However, it is important to utilise effective forms of enrichment in a manner...

  10. The effect of auditory enrichment, rearing method and social environment on the behavior of zoo-housed psittacines (Aves: Psittaciformes); implications for welfare

    | Contributor(s):: Williams, Isabelle, Hoppitt, Will, Grant, Rachel

    The psychological and physiological effects of different genres of music are well documented in humans. These concepts have also been studied in kenneled dogs and some exotic animals, implying that animals may experience benefits similar to those of humans. This study tested the hypothesis that...

  11. The effect of combining different environmental enrichment materials on enrichment use by growing pigs

    | Contributor(s):: Guy, Jonathan H., Meads, Zoe A., Shiel, Robert S., Edwards, Sandra A.

    EU legislation requires that growing pigs are provided with suitable materials that satisfy their needs for investigation and manipulation. Although commercial pig keepers have tried a variety of different enrichment materials and methods of presentation, the benefits to the pig have not always...

  12. The effect of different types of enrichment on the behaviour of cheetahs (Acinonyx jubatus) in captivity

    | Contributor(s):: Quirke, Thomas, O’ Riordan, Ruth M.

    Enrichment, in the form of changes to the structure and content of enclosures, in addition to changes to husbandry practice, have been used on a range of felids resulting in increased activity levels and decreased levels of pacing behaviour. It is important to determine what types of enrichment...

  13. The effect of enclosure type on the behavior and heart rate of captive coyotes

    | Contributor(s):: Brummer, S. P., Gese, E. M., Shivik, J. A.

    The potential for captivity to elicit changes in animal behavior and physiology is well known. Recent research on captive populations has examined the effect of feeding protocols, enclosure types, and enrichment programs on indices of stress and displays of species-typical behaviors. We...

  14. The effect of environmental enrichment and visitors on the behaviour and welfare of two captive hamadryas baboons ( Papio hamadryas )

    | Contributor(s):: Bortolini, T. S., Bicca-Marques, J. C.

    The welfare of zoo animals depends on a combination of physical, social, dietary and other ecological characteristics of the captive setting. We analysed the influence of the transfer of an adult couple of hamadryas baboons (Papio hamadryas) from a small and non-enriched cage that was closed to...

  15. The effect of environmental enrichment on learning in pigs

    | Contributor(s):: Sneddon, I. A., Beattie, V. E., Dunne, L., Neil, W.

    This study examined the effects of enriching the environment on the learning abilities of growing pigs. 84 pigs were housed in either barren or enriched environments from birth to 14 weeks. The barren environments were defined as intensive housing and the enriched environments incorporated extra...

  16. The effect of environmental enrichment on play behaviour in white-lipped peccaries (Tayassu pecari)

    | Contributor(s):: Nogueira, S. S. C., Soledade, J. P., Pompeia, S., Nogueira Filho, S. L. G.

    Herds of white-lipped peccary (Tayassu pecari) have historically been kept in captivity in order to replace stocks lost to hunting however the lack of knowledge regarding their species-typical behaviour remains an impediment to understanding their captive needs. Environmental enrichment has...

  17. The effect of environmental enrichment on the behaviour of caged rabbits ( Oryctolagus cuniculus )

    | Contributor(s):: Hansen, L. T., Berthelsen, H.

    Behaviour and use of the cage area were studied in 96 rabbits (Oryctolagus cuniculus) kept in an enriched cage system - with access to shelter and raised height at the back of the cage - and in a conventional cage system to estimate the effects of the environmental enrichment on the rabbits'...

    | Contributor(s):: Pullen, A. J., Merrill, R. J. N., Bradshaw, J. W. S.

    Kenneled environments often prevent direct physical contact between dogs, potentially causing stress, and so it has been recommended that such contact should be provided. This study examined the effect of familiarity on the behavior of dogs during off-lead interaction. Kenneled dogs (3 breeds)...
