Group formation of previously single-caged adult rhesus macaques for the purpose of environmental enrichment

An attempt was made to form two groups of 6 previously single-caged adult female and 6 previously single-caged adult male rhesus macaques. The study was based on the premise that simultaneous introduction of familiar animals reduces the risks involved during...
