Physiological correlates of self-injurious behavior in captive, socially-reared rhesus monkeys

This study examined the relationship between self-injurious behavior (SIB) in rhesus monkeys and several biological variables, including monoamine metabolites in cerebrospinal fluid (CSF) and circulating levels of ACTH, cortisol, and testosterone. Cisternal CSF and blood plasma samples were obtained from...

Effects of olfactory stimulation as environmental enrichment for adult cynomolgus monkeys

[Unspecified] test odours were transferred onto fleece squares. The results of this study suggests that odour is a weak stimulus for environmental enrichment of macaques.

Enrichment discussion: The sugar question

Jen, Cobie, and Brooke all agreed that corn on the cob(raw, whole, uncooked - no need to shuck!) is a great form of enrichment for macaques. ... Many do eat the outer husks. Our vet has said that they probably...

Reproductive performance of rhesus macaques (Macaca mulatta) in two outdoor housing conditions

We conclude that, for rhesus macaques, outdoor corral housing leads to better reproductive performance than does semi-sheltered gang housing, probably as a result of increased individual space and relaxation of intense social stressors.

Male pigtailed macaques neonatally separated from mothers for clinical reasons show increased abnormal behavior as adults

The proportion of the first 48 months of life spent singly housed was significantly related to abnormal behavior in maturity. It explained 12% of abnormal behavior in mother-reared animals, 42% in experimental-nursery-reared animals, and 55% in clinical-nursery-reared animals.

Long-term effects of a food puzzle on the behaviour of rhesus monkeys

Five adult males were tested during a 17 week period. Access to a food puzzle yielded an overall reduction in, or even disappearance of, the stereotyped locomotion, the stereotyped self-directed beahviours and the saluting behaviour that had been observed when...

A comparative study of reconciliation in rhesus and Tonkean macaques

Post-conflict affiliative contacts between previous opponents were compared in Rhesus and Tonkean macaques. The first contact mostly occurred in the first minute following conflict. Among unrelated females, conciliatory tendencies rated fivefold higher in Tonkean macaques than in rhesus macaques. This...

Compatibility of laboratory monkeys housed in grooming-contact cages varies by species and sex

At the Washington Regional Primate Research Center, we promote grooming-contact caging as a means to provide laboratory monkeys with tactile social contact while maintaining research access to animals housed individually. Grooming contact is achieved through widely spaced vertical bars that...

Puzzle Ball foraging device for laboratory monkeys

We wanted a foraging device that was inexpensive, durable, and effective, and that could be sanitized during routine cage washing. .. An earlier design of this foraging device was developed by Murchison (1992). The design described here includes modified access...
