Abstract:Objective To establish a hedth evaluation system and to evaluate the health status of captive rhesus macaques. Methods Combined with more than 10 years of breeding management experience with rhesus macaques, 500 rhesus macaques were evaluated in this study. The evaluation involved grading rhesus macaques by observing their mental status, feeding status, physical health status, short-term weight gain, age, and obesity. Then, a comprehensive score was obtained according to a certain weight ratio. Results Based on the comprehensive score, the current condition of the animals was divided into four levels: fine, good, normal, and bad. Conclusions This study provides the scientific basis for breeding management and disease prevention of rhesus macaques.
