Laboratory assessment of temperament and environmental enrichment for rhesus monkey infants (Macaca mulatta)

Results indicated that enrichment [for infants who were separated from their mothers] was associated with higher scores on subsequent problem-solving and motor tests.

Effects of environmental enrichment on the social behavior of pair-housed juvenile specific pathogen free (SPF) rhesus monkeys

These results emphasize the necessity of matching the enrichment technique with the desired behavioral outcome.

Technical note: A primatrail or an inexpensive cage expansion for group housing small primates

An inexpensive method for converting standard laboratory cages into colony units for housing small primate species is described. In addition to increasing the volume of space available to the animals, this system also provides a complex of climbing, running, jumping,...

Rearing infant monkeys (Macaca nemestrina) in pairs produces deficient social development compared with rearing in single cages

Many scientists and colony managers assume that social housing is a beneficial living condition for all captive primates. Several older studies of primate development question the generality of this assumption. We recently tested this assumption by comparing the social development...

A prescription for psychological well-being

By far the most common physical problem that I treat as clinical veterinarian is trauma sustained by macaques in group-housing situations.

Three inexpensive environmental enrichment options for group-housed Macaca mulatta

We distributed the following enrichment materials on the floor once a week, each on a different day: (1) 1 kg roasted peanuts in their shells; (2) 32 ears of hard corn; (3) one non-corrugated cardboard box. ... After a habituation...

The use of artificial turf as a foraging substrate for individually housed rhesus monkeys (Macaca mulatta)

In this study artificial turf was used as the substrate for a particulate food given to the subjects as an environmental enrichment technique. When their cages were not enriched, eight single-caged subjects exhibited abnormal behaviors approximately 37% of the time....

A preliminary survey of the incidence of abnormal behavior in rhesus monkeys (Macaca mulatta) relative to housing condition

To assess the behavioral status of individuals from one nonhuman primate species housed in different social [single vs group] and physical environments [corn crib vs indoor/outdoor run], we conducted a survey of abnormal behaviors in rhesus monkeys ... The greatest...

Evaluation of the preference to and behavioral effects of an enriched environment on male rhesus monkeys

With simultaneous exposure, the single-housed subjects spent the greatest portion of the interactive time [30 minute-observation sessions] on the perch [16.8%], the second greatest amount of time spent divided approximately equally between interacting with the Kong [5.0%] and Tug-A-Toy [4.9%],...

Removing an environmental enrichment device can result in a rebound of abnormal behavior in rhesus monkeys

These studies have repeatedly documented a 'rebound' of abnormal behavior of our subjects, typically at levels higher than that observed in the original baseline condition, when the devices are removed during the course of the study.
