A practical assessment of a non-human primate exercise program

In two different heterosexual groups of eight adult capuchins aggressive interactions were absent when the familiarized, carefully preselected single-caged subjects were introduced in a large exercise cage.Rhesus macaques engaged in a serious aggressive interactions in the same situation.

Environmental enrichment objects and singly housed rhesus monkeys: Individual preferences and the restoration of novelty

We found that the extent of physical contact with the [Kong toy, Nylabone ring and Nylabone ball] toys habituated during a short time. ... The introduction of a different toy every Monday was accompanied by a restoration of the apparent...

Environmental enrichment for Macaca fascicularis: Effects of shape and substance of manipulable objects

The ring was the most effective shape and the translucent flexible plastic was the most effective substance. Some abnormal self-directed behavioral patterns decreased significantly in the presence of manipulable objects. [Age of animals is not indicated.]

Impaired performance from brief social isolation of rhesus monkeys (Macaca mulatta): A multiple video-task assessment

Both the number and the quality (i.e., speed and accuracy) of responses were significantly compromised in the social isolation condition relative to levels in which the animals were tested together.

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.

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...
