Environmental Enrichment

Enhancement of laboratory environments for primates: Effective enrichment and innovative enclosures for biomedical research

The provision of objects such as commercially available toys for pet dogs was found to be highly effective in reducing rates of self-directed abnormal behavior or completely eliminating it. No data are included in this abstract.

A grass foraging device for captive chimpanzees (Pan troglodytes)

In the wild, chimpanzees spend most of their time foraging, so any device that stimulates this behaviour in captivity could potentially be effective enrichment. A simple grass foraging device constructed of a polyvinyl chloride (PVC) pipe cut in half lengthwise...

Recycled plastic cages and environmental enrichment devices

Although the production and use of recycled plastic lumber is still in its infancy, our experience indicates that this is an ideal material for the construction of environmental enrichment devices for monkeys ... especially in outdoor facilities and zoological collections.

Rate of habituation to an enrichment device by rhesus macaques with lesions of the entorthinal cortex, hippocampal formation, or parahippocampal gyrus

Significant differences were found in the rate of habituation [to a rubber ball serving as enrichment] between animals with entorhinal or hippocampal lesions and normal control animals. This study addresses the special needs of monkeys with experimental cortical lesions and...

Short-term evaluation of a foraging device for non-human primates

In the USA, any institution involved in using non-human primates for research has had, for regulatory reasons, to address the psychological needs of these animals. Enriching the environment through the use of foraging devices has been one method and a...

Frozen enrichment for chimpanzees

We gave this enrichment [frozen juice container] to 19 chimpanzees of different ages and found that it took from 24 to 48 minutes for each chimp to consume the frozen treat.
