The presence of visual barriers decreases antagonism in group housed pigtail macaques (Macaca nemestrina)

Instances of bite, grab and chase were found to be significantly greater [among members of harem groups of 23 pig-tailed macaques] when visual barriers were absent compared to when they were present.

Successful pair-housing of male macaques (Macaca fascicularis)

Potential companions were paired after establishment of a clear dominance-subordination relationship during a noncontact familiarization period. Throughout a follow-up period of 12-42 months, 16 of the 17 original pairs (94%) were compatible. Only one pair engaged in fighting shortly after...

Pairing female Macaca fascicularis

Twenty-nine previously single-caged adult female long-tailed macaques were paired with each other in vertical, double-cage configuration. Partners were compatibly in 81% of cases. Neighboring pairs were often charging each other across the grid panel. ... To avoid this, pairs were...

Cage toys reduce abnormal behavior in individually housed pigtail macaques

Providing multiple manipulable toys as enrichment for [single-caged] pigtail macaques was effective in reducing abnormal behavior during 30- min observation session. The use of the toys was reduced over time. The Kong toy was used most consistently.

Social enrichment in captive lion-tailed macaques (Macaca silenus) by means of group encounters

During 20 repeated encounters, the macaques were able to see, smell and hear members of a second group. ... During encounters the macaques were able to display a larger proportion of their natural behavioural repertoire. The original German paper of...

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.
