Behavioral effects of enrichment devices on laboratory primates with stereotypic and self-directed behavior

Single-caged long-tailed macaques showed a decrease in self-directed behavior, especially self-biting, floating limb, hair pulling, and excessive licking, when treats were in the feeder. Paradoxically, both pacing and rocking increased when treats were in the feeder. A temporary reduction in...

Reasons and risks associated with manipulating captive primates’ social environments

Review of the implications of experimental or management-related manipulations of the social environment of captive primates for the animals' welfare. Relatively little empirical work has been done on the effects of manipulation of the social environment. The data currently available...

All-male social group formation: Does cutting canine teeth promote social integration?

Groups were formed by releasing future group members in same enclosure. Within the first five months after group formation one of 26 animals died and two were killed due to trauma resulting from fighting. We decided to use the webinar...

Results of providing swings to individually housed rhesus monkeys (Macaca mulatta)

The single-housed adult test subjects manipulated the swings but showed little inclination to actually use them for swinging.

Sex differences in compatibility of pair-housed adult longtailed macaques

Prefamiliarized partners were paired without ascertaining that they had established their dominance-subordination relationship. Newly formed pairs were separated for 17 hours and subsequently reintroduced daily during a study period of 23 days. Under these extraordinary circumstances male/male pairs were less...

Challenging conventional wisdom for housing monkeys

Our research indicates that the minimum cage size does provide adequate space for the monkeys that we studied [adult long-tailed macaques of both sexes]. Our studies [with barren cages] also lead us to the conclusion that spending millions of dollars...

Reproductive performance in captive breeding groups of Macaca mulatta: Gang cages versus outdoor corrals

Overall, outdoor corral housed animals had higher reproductive performance in comparison to gang-cage housed animals (further analysis showed that this was not a result of differential age structures or virological status). We thought that this may be a result of...

Assessing group housing for an aged female rhesus macaque

It was demonstrated that the well-being of a 30 year old female rhesus macaque was not jeopardized by the fact that she permanently lived in a stable breeding group.

Psychological well-being in paired adult female rhesus (Macaca mulatta)

Pair formation technique is described; 86% success rate. Paired females show strong preference to spend time in close proximity [approximately 80% at night, 40% at day]; agonistic behaviors are very infrequent. Health measures, body weight gains, reproduction and immune responses...
