Objective To evaluate the influences of environmental enrichment on the behaviors of long-term individuallycaged cynomolgus macaques. Method A total of 30 cynomolgus macaques were randomly divided into two groups: control group( group A,n = 15) and environmental enrichment group( group B,n = 15). Cynomolgus macaques of each group were kept in the single cage( 0. 7 m × 0. 8 m × 0. 9 m) respectively. The cage of group A facing the wall was provided only with the feed trough and drinking fountains. In contrast...
