Social Housing & Companionship

Alternatives to single caging of rhesus monkeys (Macaca mulatta) used in research

Single-housed rhesus macaques were transferred to permanent pair-housing arrangements. The present investigation also demonstrates that pairing caged rhesus monkeys with compatible conspecifics does not interfere with a number of common research protocols [e.g., headcap implantation, experimental surgery, blood collection]. Our...

Facilitated socialization of previously singly caged adult rhesus macaques (videotape with accompanying text)

Thirty scenes depict different adult rhesus monkeys [and one adult, male stump-tailed macaque], each paired with a compatible companion for up to two years. The following pair combinations and research situations are shown: adult male/male, adult female/female, adult male/juvenile male,...

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).

Time budget of caged rhesus monkeys exposed to a companion, a PVC perch and a piece of wood for an extended time*

Sixty animals were continuously exposed for at least 1.5 years to a compatible companion for social interaction, a suspended plastic pipe for perching, and a branch segment for gnawing. ... Individuals spent an average of 23.5% of the time interacting...

Environmental enrichment for marmosets

Marmosets are among the easiest of primates to provide with environmental enrichment. Like other higher primates, they need companionship, adequate space with incorporated complexity, some unpredictability in the environment, ways in which they can manipulate or control their environment.

Xenospecific enrichment at the Primate Research Institute

Nursery reared, single-housed and group-housed chimpanzees were exposed to a puppy after careful prior familiarization. ... The complete physical introduction [with single-caged subject] initially resulted in tugs-of-war over toys and blankets. The chimpanzee would alternately grimace, whimper-woo, or initiate play...
