A Tail of Two Monkeys: Social Housing for Nonhuman Primates in the Research Laboratory Setting

Despite great adaptability, most nonhuman primates require regular tactile contact with conspecifics for their psychological well being. By illustrating the inherent value of social contact and by providing clues to the best ways of satisfying this need, behavioral studies are useful in designing social enrichment programs. Although group housing is ideal for most gregarious primates, […]

Presence of a privacy divider increases proximity in pair-housed rhesus monkeys

Use of a privacy panel in the home cage of female pair-housed rhesus monkeys has been reported to increase time spent in close proximity and time spent in affiliative behaviours. In the current study we measured these behaviours in more diverse populations; including male-male and male-female pairs of monkeys actively participating in cognitive experiments. We […]

Effects of Enrichment on Veterinary Treatment of Laboratory Rhesus Macaques (Macaca Mula1ta)

For captive primates, environmental enrichment may improve psychological well-being, as indicated by changes in the frequency of species-typical and abnormal behaviours. The effects of enrichment on physical well-being have also been examined, but little attention has been devoted to the relationship between enrichment and animal health. We therefore studied the health records of 98 rhesus […]

Comparing the relative benefits of grooming-contact and full-contact pairing for laboratory-housed adult female Macaca fascicularis

Tactile social contact is the most effective form of environmental enrichment for promoting normal behavior in captive primates. For laboratory macaques housed indoors, pair housing is the most common method for socialization. Pairs can be housed either in full contact (FC), or in protected contact (PC). At Washington National Primate Research Center, PC is provided […]

Is Full Physical Contact Necessary for Buffering Effects of Pair Housing on Social Stress in Rats?

Our previous study showed that pair housing with a familiar male prevented an increase in anxiety caused by social defeat in male rats. The present study attempted to identify the aspects of social interactions with a familiar male that are needed for the emergence of such a pair-housing effect. In Experiment 1, the subject was […]

Pair housing for female longtailed and rhesus macaques in the laboratory: Behavior in protected contact versus full contact

Pair housing for caged macaques in the laboratory generally allows unrestricted tactile contact but, less commonly, may involve limited contact via grooming-contact bars or perforated panels. The purpose of using this protected contact housing, which prevents entry into pair-mates’ cages, typically is to accommodate research and management requirements. The study used behavioral data collected on […]
