Training stumptailed monkeys to cooperate during in-homecage treatment

One to 14 training sessions, each lasting for 1-5 minutes, were required to train adult, pair-housed and single-housed stump-tailed macaques of both sexes to cooperate during topical treatment in the homecage.

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...

Social enrichment for laboratory primates: A critical review

23% (54/237) of individually caged, but only 10% (38/382) of pair-housed rhesus monkeys required medical treatment. A photograph shows a compatible pair of adult males who have been reared as social isolates.

A perch for caged macaques

Wooden and plastic perches have been tested successfully by several hundred rhesus monkeys and 40 stump-tailed monkeys of both sexes and various ages over the last 3 years. Perches have proven an inexpensive, simple, yet effective environmental enrichment for these...

Provision of manipulable objects to cynomolgus macaques promotes species-typical behavior

A different pet toy was provided to each [single-caged] monkey during six weeks. Self-directed abnormal behavior was reduced or eliminated in all subjects in the presence of objects but increased after removal of the toys.
