A bullock with history of viper snake envenomation was dull, depressed and had uncoordinated gait and salivation. There was marked swelling of the right hind limb from pastern up to mid thigh and at ventral abdomen region around the prepuce. On physical examination of the swollen right hind leg revealed fang marks with blood clot near the pastern and the extremity was cold with reduced reflexes. Animal had decreased rectal temperature, respiration and heart rate. The hematological examination revealed decreased hemoglobin and PCV and an increased total leukocyte count. The biochemical values showed elevated levels of ALT, AST, ALP and creatinine. Animal was treated with lyophilized polyvalent snake antivenin, dexamethasone, tetanus toxoid, amoxicillin and cloxacillin, ketoprofen and frusemide. Using 16G needles under aseptic precautions, blood tinged edematous fluid was drained out from the swollen areas. The animal recovered uneventfully.
