Guidelines for developing and managing an environmental enrichment program for nonhuman primates

The importance of evaluating any enrichment program cannot be overstated. Quantitatively measuring animals' responses to the enrichment(s) is certainly the best way to evaluate an item or procedure.

The reduction of abnormal behaviors in individually housed rhesus monkeys (Macaca mulatta) with a foraging/grooming board

All of the single-housed animals foraged from the board to the point that a significant reduction in the level of abnormal behavior [5%] was noted. Most animals also groomed the fleece covering the board. Subjects spent on average 12 minutes...

Social housing ameliorates behavioral pathology in Cebus apella

No specific enrichment devices were included in the [single-] cages. The seven subjects' mean percentage of occurrence of stereotypic behaviors was 13%.Change from single- to group-housing effectively reduced stereotypic behaviors; however, it also was associated with more passive behaviors being...

Providing environmental enrichment to captive primates

A very useful introduction to the principles of environmental enrichment. A preventive approach to providing for the psychological well-being of captive primates may include the following: (1) the provision of compatible social partners if the species is social in nature...
