摘要: Abstract Male lambs were raised under three different social conditions: in isolation, with peers, or their mothers small flocks. Differential rearing conditions significantly affected the lambs' behavioral response to open-field testing at 14 days of age. The isolate-reared exhibited withdrawal behavior as compared other groups. When retested 42 age, differences between groups attenuated; however, continued exhibit behavior. Although displayed responses stress, there was no difference adrenocortical response.
