Environmental Enrichment

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...
