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...

Primate puzzleboard: A simple environmental enrichment device for captive chimpanzees

Treat-loaded transparent board with finger holes is attached to the top of the cage. Mean 'puzzle use' during four 60-minute trials was 17%.

Objective criteria of enrichment

39 cotton-top tamarins living in four families were observed following stimulating husbandry procedures [capture, birds passing overhead]. Arousal led to an improvement in behaviour (i.e., decrease in activity and an increase in affiliation) during the remainder of the day.

Use of a grooming and foraging substrate to reduce cage stereotypies in macaques

We examined the effects of a synthetic fleece pad on cage stereotypies in individually housed cynomolgus monkeys. Animals exhibited idiosyncratic repertoires of stereotyped behaviour, including repetitive pacing, swaying circling, bouncing, cage charging, and rocking that occupied on average 11% of...
