Macaque

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...

Recycled plastic cages and environmental enrichment devices

Although the production and use of recycled plastic lumber is still in its infancy, our experience indicates that this is an ideal material for the construction of environmental enrichment devices for monkeys ... especially in outdoor facilities and zoological collections.

Removal of a trauma-inflicting alpha matriline from a group of rhesus macaques to control severe wounding

Results identify an unusual outbreak of serious wounding by the alpha matriline of a large captive group [of rhesus macaques] and indicate that identification and removal of the animals responsible can be an effective management procedure for controlling such injuries.

Rate of habituation to an enrichment device by rhesus macaques with lesions of the entorthinal cortex, hippocampal formation, or parahippocampal gyrus

Significant differences were found in the rate of habituation [to a rubber ball serving as enrichment] between animals with entorhinal or hippocampal lesions and normal control animals. This study addresses the special needs of monkeys with experimental cortical lesions and...

Short-term evaluation of a foraging device for non-human primates

In the USA, any institution involved in using non-human primates for research has had, for regulatory reasons, to address the psychological needs of these animals. Enriching the environment through the use of foraging devices has been one method and a...

Effect of a preferred companion in modulating stress in adult female rhesus monkeys

Adult female rhesus monkeys exhibited a profound stress response when removed from their social group to a novel environment. Recovery time [of T cell subsets] was significantly enhanced by the presence of a preferred companion.
