Abnormal behavior in singly-housed Macaca mulatta: Prevalence and potential risk factors

Behavioral assessments of individually-housed animals indicate that 321 of 362 animals exhibited at least one abnormal behavior (median:2, range 1-8). The most common behavior was pacing. Males showed more abnormal behavior than females. Older animals exhibited more eye poking, hair...

Techniques for collecting saliva from awake, unrestrained, adult monkeys for cortisol assay

Cortisol levels serve as an index of pituitary-adrenal activity in nonhuman primates. In adult monkeys, cortisol is normally measured in blood (typically requiring restraint or sedation) or urine (reflecting a state rather than point estimate). In contrast, saliva collection is...

A novel approach to group-housing male cynomolgus macaques in a pharmaceutical environment

Twenty percent of our primates are maintained in a single-housed environment. Of those single-housed animals, 40% exhibited moderate to marked degrees of self-directed activity; i. e., hairpulling. By contrast, none of the pair or group-housed animals exhibited these behaviors. Our...

Environmental enrichment-related injury in a macaque (Macaca fascicularis): Intestinal linear foreign body

As a result of this incidence [ingested sisal rope pieces leading to multiple ulcerations, perforations, septic peritonitis] sisal rope enrichment devices were immediately removed from all macaque cages in the facility.

Activity of the hypothalamic-pituitary-adrenal axis is altered by aging and exposure to social stress in female rhesus monkeys

The effects of age on the response to two doses of dexamethasone and two doses of CRF were assessed in females living in a stable social environment (control) and in socially stressed females removed from their group and housed temporarily...

Environmental enrichment for rhesus macaques: A cost-effective exercise cage

A movable exercise cage for rhesus macaques is described. Within our facility, increased visual attentiveness by other animals, decreased self-directed biting and hair picking, and improved food consumption was observed when rhesus macaques were permitted access to an exercise cage...

Social awareness in monkeys

Tests of self-awareness in nonhuman primates have to date been concerned almost entirely with the recognition of an animal's reflection in a mirror. By contrast, we know much less about non-human primates' perception of their place within a social network,...

The lower-row cage may be dark, but behavior does not appear to be affected

The situation of 3 upper-row single-caged females was compared with that of 6 lower-row single-caged females. Mean light levels at nine different positions within the cage were significantly lower in bottom-row cages than in upper-row cages. Not only did light...

A comparison of cell-mediated immune responses in rhesus macaques housed singly, in pairs, or in groups

The data demonstrate that social housing condition affects immune responses. While not unidirectional, these effects generally suggest enhanced immune responses for socially housed animals. .... It is our contention that strong social relationships, particularly the affiliative interactions that characterize our...
