Abstract

Authors evaluated plasma corticosteroid concentrations in male rhesus macaques who were trained to enter voluntarily a restraining apparatus and permitted venipuncture without showing signs of stress. Basal cortisol values were 30% lower than previously reported for different, untrained animals.
