Increased cage size does not alter heart rate or behavior in female rhesus monkeys

The behavioral and heart rate responses of 10 female rhesus monekys to three different-sized, barren cages were measured. No differences were found and the conclusion drawn that the proposed [by USDA, 1985] changes in cage size will not improve well-being...

Preliminary comments on resocialization of aged macaques

Group formation technique is described. Each rhesus monkey [6 males and 7 females] was introduced to group members in a series of brief pair tests. Despite the number of injuries, and the death of one monkey, we view the resocialization...

Behavioral responses of female long-tailed macaques (Macaca fascicularis) to pair formation

Pair formation technique is described. Five of six pairs tested were compatible during a five to six months study period. Self-abusive behaviors were recorded for five of the ten subjects when singly housed, but were completely absent after pair formation....

Responses of female rhesus macaques to an environmental enrichment apparatus

The apparatus consisted of a box attached to the monkey's home cage that contained a radio and a food dispenser, which could be controlled by the monkeys via contact detectors.

Social housing of a timed-mating rhesus monkey colony

Even though fighting was a problem in group-housed animals, the fertility rate was approximately 45%. These results indicate that timed-mating may be performed successfully within socially [grouped] housed macaques.

The effects of four types of restraint on serum alanine aminotransferase and asparate aminotransferase in the Macaca fascicularis

All methods of restraint resulted in elevation in AST [aspartate aminotransferase] and ALT [alanine aminotransferase] over time.

Well-Being of Nonhuman Primates in Research

It is generally agreed that for social species of nonhuman primates, social interaction with other nonhuman primates is probably the optimum enrichment possibility (p. 114).

Increasing foraging opportunities for a group of captive capuchin monkeys (Cebus capucinus)

The [group-housed] monkeys avidly searched for and removed food from the feeders, displaying a wide variety of manipulative abilities.
