Hematological indicators of large wild representatives of cat families

Information was obtained on morphometry, biochemistry, and the enzymatic profile of the blood of a tiger, a lion, and a snow leopard, which will make it possible in the future to increase the level of diagnostic studies in these animals. Significant differences were found in tigers and lions in the number of erythrocytes, in tigers and snow leopards in the number of leukocytes, and in lions and snow leopards in the number of erythrocytes and leukocytes. The highest amount of alanine aminotransferase and alkaline phosphatase was observed in tigers, the smallest - in the snow leopard. By the number of aspartate aminotransferase, the lion is in the lead, and the minimum is observed in the snow leopard. The amount of amylase was greatest in lions, followed by tigers, and the least amount of this enzyme occurred in the snow leopard. Gender differences were studied in tigers and a greater amount of alanine aminotransferase, aspartate aminotransferase and alkaline phosphatase was detected in the female, and amylase in the male. It should be noted that due to the small sample, the data obtained should be considered as preliminary.
