Hematology and blood biochemistry of captive mugger crocodiles (Crocodylus palustris).
Comprehensive hematologic and biochemical analyses were conducted on blood from 23 male and 31 female clinically stable captive mugger crocodiles (Crocodylus palustris). Erythrocyte mean corpuscular volume (MCV), potassium, cholesterol, and calcium concentrations were significantly greater in juvenile males than in juvenile females, but no significant differences were determined between parameters of subadult males and subadult females. The mean WBC count and mean heterophil count were significantly higher in adult males than in adult females. Mean uric acid concentration was significantly greater in adult females than in males. Mean erythrocyte count was significantly higher in adults than in juveniles. Adult mean WBC and lymphocyte counts were significantly lower than those of both juveniles and subadults. Subadults had significantly lower mean eosinophil counts than both adults and juveniles. Subadults had significantly lower mean alkaline phosphatase activities than juveniles, whereas the adults had significantly lower aspartate aminotransferase and alanine aminotransferase activities than other groups. Lactate dehydrogenase activities were significantly lower for subadults than for juveniles and adults. Cholesterol concentrations were significantly higher for subadults and juveniles compared with adults. Triglyceride concentration was significantly lower for subadults and highest for juveniles. Glucose concentrations were significantly higher for adults. Blood urea nitrogen was significantly lower for subadults than for both adults and juveniles. Uric acid concentrations were significantly higher for juveniles than for the subadults and adults. The subadult animals also had a significantly lower potassium concentration. The results obtained were then compared with known values for other crocodilian species.
