Body condition score (BCS) and blood pressure were investigated in clinical examinations. The study population was semicaptive and used in Myanmar's timber industry, but maintained natural feeding and breeding behavior. Longitudinal health data were collected from clinical examination, hematology, and serum chemistry analyses over 3 yr from 227 healthy individually marked Asian elephants varying in age and sex. Natural variation in the health of the long-lived Asian elephant ( Elephas maximus) is poorly understood, particularly in relation to differences between males and females.

The reference intervals of health parameters are valuable tools for veterinarians and conservationists to monitor the health status and viability of endangered species.
