Risk factors for self-injurious behavior in captive rhesus monkeys (Macaca mulatta)

Research has shown that approximately 10% of captive, individually housed monkeys have had some veterinary record of self-injurious behavior within their life-time. The incidence of self-biting was 14% [!] in a test colony of 188 male individually housed rhesus macaques....

Effects of dominance status and environmental enrichment on cell-mediated immunity in rhesus macaques

These data demonstrate that dominance rank, an important psychological factor, affects immune response in a stable social [group-housing] setting. Findings suggested that inanimate enrichment may subtly affect cell-mediated immune response.

Discussion: A plea for pair-housing of adult macaques

Practical implications of several attempts of pair formation and subsequent permanent pair-housing protocols of previously single-caged adult macaques are discussed. Of 165 pairs reported, 97% were compatible during pair formation.

The effect of duration of individual housing on social behavior of adult male bonnet macaques (Macaca radiata)

Already familiar adult male bonnet macaques were moved from one-month, and 24-month temporary single-housing to pair- and trio-housing situations. The males were only given the opportunity for social integration [in a playpen] one day [for four hours] each day. ......
