Most populations of wild felines are now considered endangered or near extinction due to the indiscriminate hunting and the reduction of their natural habitat, caused by man. Due to the limited number of animals within a population, these species are especially vulnerable to the impacts of diseases and endogamy. In addition, wild felines are also susceptible to metabolic and behavioral changes related to a change in their natural conditions, habitat, and feeding, when the animal enters into captivity. There are few descriptions in the literature of the serum biochemistries of lions and tigers. This study presents the biochemical parameters of 23 captive lions (Panthera leo) and 10 captive Siberian tigers (Panthera tigris altaica) from the Zoological Park of the Sao Paulo Foundation. Serum urea, creatinine, total protein, albumin, total, direct and indirect bilirubin were measured. In addition, serum levels of ALT, AST, ALP, GGT, glucose, CK, lactate dehydrogenase, cholesterol, and triglycerides were determined, as well as calcium, phosphorus, chlorine, sodium, and potassium. Biochemical parameters did not differ significantly among males and females lions, but higher albumin values were observed in male Panthera tigris altaica in comparison to females. The values obtained in this study may be used as reference for captive individuals of Panthera leo and Panthera tigris altaica.
