Environmental Enrichment

A perch for caged macaques

Wooden and plastic perches have been tested successfully by several hundred rhesus monkeys and 40 stump-tailed monkeys of both sexes and various ages over the last 3 years. Perches have proven an inexpensive, simple, yet effective environmental enrichment for these...

Environmental enrichment program for caged stump-tailed macaques (Macaca arctoides)

An effective social and inanimate enrichment program for caged stump-tailed macaques is described. Paired companions interacted with each other 22% of the time, they used the PVC perch 4.2% of the time, and the gnawing stick 5.7% of them time.

Primate psychological well-being: A comparative approach to environmental enrichment for captive primates

The presence of woodchips and especially the introduction of [unspecified] objects, reduced general locomotor activity in the capuchins; however, the objects had no such effect on the lemurs, and the provision of woodchips plus grain almost doubled their rates of...

Environment enrichment for the laboratory pig

This brief paper attempts to illustrate the simple ideas that can be used to enhance the environment of the laboratory pig. ... It does not describe the behaviour of the pig in any detail but suggests that with a little...

Behavioral enrichment of a group of captive gorillas: A quantitative study

Introduction of embedded foods [novel or preferred foods inside burlap bags and various paper and cardboard containers] resulted in decreases in regurgitation and reingestion, inactivity, and aggression, accompanied by increases in solitary and social play.

Evaluation of a chimpanzee enrichment enclosure

A large, three-part playground for captive chimpanzees was constructed and evaluated in terms of area use and behavior changes. Comparative behavioral samples were obtained on 38 subjects in the existing indoor-outdoor run and in the enclosure. The chimpanzees used the...
