Macaque

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...

Comparing the effectiveness of PVC swings versus PVC perches as environmental enrichment objects for caged female rhesus macaques

Single-housed subjects' preference for perches was probably related to the fact that perches, unlike swings, are fixed structures permitting continuous relaxed postures rather than short-term balancing. Moreover, perches, unlike swings, permit the animals to sit right in front of the...

A unique housing system for rhesus macaques

From each bank of four dog cages, we removed the ceilings of the lower two cages, making a single housing unit for macaques. To each cage we added three resting perches, a climbing ladder, windows on both sides, and a...

Formation of a new social group of unfamiliar female rhesus monkeys affects the immune and pituitary adrenocortical systems

Eight adult females were introduced into an enclosure. Initial dominance rank was established within 48 h by noncontact threats and chases and was unchanged throughout the [9-week] study. Only two minor wounds were recorded. The animals showed stress responses during...

Applied primate ecology: Evaluation of environmental changes to promote psychological well-being

In one [non-referenced] study of longtailed macaques, self-directed aggressive behavior was suppressed (relative to baseline) in the presence of a manipulable object for more than five months, for four out of five animals.

The effects of temporary cover on the behavior of socially housed Stumptailed macaques (Macaca arctoides)

To examine the effects of the provision of temporary cover on the behavior of stumptailed macaques (Macaca arctoides), a single group of 26 animals was observed during 25 testing periods over 7.5 months. During each testing period, the group was...
