Preliminary comments on environmental enrichment with branches for individually caged rhesus monkeys

The branches not only were attractive to the majority (87%) of [single-housed] animals but they were also inexpensive and easy to install and to clean.

Social enrichment of the environment with infants for singly caged adult rhesus monkeys

Twenty-nine weaned rhesus monkey infants were removed from breeding troops to avoid overcrowding and were placed with unfamiliar singly caged adults without prior familiarization. Adult-infant pairs were compatible in 90% of cases. Compatibility depended neither on the sex, age, or...
