Mynahs are popular pet and aviary birds. Captive mynahs are prone to metabolic disorders, such as obesity, hepatic lipidosis, and atherosclerosis, and determination of a plasma biochemical reference interval is essential for diagnosis, treatment, and monitoring of these disorders. To establish reference intervals for the lipoprotein panel and plasma activity of liver enzymes in common mynahs (Acridotheres tristis), glucose, cholesterol, triglycerides, high and low density lipoprotein concentrations, and activities of aspartate aminotransferase, alkaline phosphatase, gamma-glutamyl transferase, and lactate dehydrogenase were measured in 56 adult healthy individuals. The data were grouped according to sex and body weight. For all variables, no significant differences were found between male and female mynahs, and body weight had no effect on lipoprotein fractions. Our results provide a reliable reference interval for some blood biochemical values in healthy common mynahs that could be useful for diagnosing and monitoring disease problems.
