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...

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...

The social nature of primates

A discussion of the social nature of primates in relationship to psychological well-being. Physiological, immunological, and neurological measures collected on isolation-reared (and hence psychologically deviant) nonhuman primates might not be representative, and therefore might be suboptimal for the development 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...

Social pairing of longtailed macaques with preferred, nonpreferred, and randomly assigned cagemates

Pair formation technique is described. All 15 [female-female] pairs were sufficiently compatible that none had to be separated.

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...
