The effectiveness of cage toys in reducing abnormal behavior in individually housed pigtail macaques

Abnormal behavior accounted for 24% [!] of the time during baseline observations. The repeated provision of several toys resulted in a significant decrease in abnormal behaviors during the first 30 minutes. The new toys were used for 27% of the...

Group formation of female pigtail macaques (Macaca nemestrina)

Eight adult females and one adult male were moved from individual cages and simultaneously introduced. The animals showed conspicuous physiological stress responses though they established a dominance hierarchy with no serious fighting and a complete absence of wounding.

Effect of companions in modulating stress associated with new group formation in juvenile rhesus macaques

To determine if the presence of one or more familiar peers buffers the physiological effect of a stressor, 10 juvenile rhesus monkeys were removed from their natal group and placed together to form a new peer group. Six of the...

Multiple daily dosing regimens need not be a barrier to group housing of primates undergoing toxicology studies

It is demonstrated how same-sex group-housing of long-tailed macaques and regulatory toxicology are compatible.

Hormonal response to restraint in rhesus monkeys

These experiments indicate clearly that placement in a restraining chair represents a stimulus of different systems in monkeys. The responses observed in the present study are predominantly psychoendocrine responses to unconditioned emotional stimuli associated with the chair-restraint situation, despite the...

Diarrhea and peritonitis due to traumatic perforation of the stomach in a rhesus macaque (hardware disease)

Abdominal radiographic views indicated ingestion of approximately 20 pieces of wire that came from an old automobile tire hung in the outdoor monkey pen to provide environmental enrichment.

Factors affecting the expression of self-injurious behavior in rhesus monkeys (Macaca mulatta)

Approximately 10% of laboratory housed rhesus monkeys spontaneously develop self-injurious behavior (SIB) such as biting their own bodies with sufficient force to produce tissue damage. ... Monkeys with SIB tended to spend a somewhat greater proportion of their lives in...

Foraging device for singly housed longtailed macaques does not reduce stereotypies

All [10 single-housed] subjects manipulated the foraging boards, but stereotyped behaviors and activity levels were not significantly affected by the presence of the boards. Subjects used the boards approximately 2 minutes per 30 minute-observation sessions. No reduction in board usage...
