Environmental Enrichment

The use of waste plastic piping for enrichment devices and cage furniture in primate enclosures at Edinburgh Zoo

This simple plastic tubing circle can be used as a very flexible piece of cage furniture; it swings freely in the enclosure and can be moved from one area to another easily. ... The level of interest obviously increased when...

Long-term use of television, balls, and mirrors as enrichment for paired and singly caged chimpanzees*

Chimpanzees used televisions, balls, and mirrors for 0.27-1.53% of the observation time after several years of exposure to the enrichment items. Television and ball use were significantly higher than mirror use. *Abstract of this work has been published in: American...

Toys for the boys: Environmental enrichment for singly housed adult male macaques (Macaca fascicularis)

Structural enhancements and enrichment toys and devices are listed. The opportunity to chew and tear has also benefited the animals' dental health.

The physiological and behavioral effects of radio music on singly housed baboons

The response of four singly caged baboons to radio music was measured using behavioral and physiological indices. Heart rate and blood pressure, measured through a tether system, as well as behavior, were recorded during a two-week period in which radio...

The behavioural priorities of laying hens: the effects of two methods of environmental enrichment on time budget

Environmental enrichment and/or feeding from the [woodchips] litter reduces agonistic behaviour and possibly frustration.

Effect of environmental enrichment and housing density on immune system reactivity to acute exercise stress

Keeping mice in enriched cages rather than barren standard cages seems to enhance immune function. Environmentally enriched mice behave immunologically much like nonstressed animals. Animals in enriched environment showed a less variable, better regulated immune response.

Environmental enrichment for laboratory mice: preferences and consequences

Current laboratory housing systems have mainly been developed on the basis of ergonomic and economic factors. These systems provide adequate, basic physiological requirements of animals, but only marginally fulfill other needs, such as the performance of natural behaviour or social...

Laboratory mice persist in gaining access to resources: a method of assessing the importance of environmental features

By using traverses of shallow water in two experiments, it was determined how laboratory mice defended gaining access to feed, shelter, a conspecific or increased space (Experiment 1), and to feed, a running wheel, enrichments ('toys') or deep sawdust (Experiment...

Effects of physical and social environmental enrichment on the behavior of juvenile chimpanzees

No behavioral differences (interaction with physical environment, locomotion, rocking) were found between pair-housed and single-housed animals.
