Atresia ani is a congenital defect in newborn calves where the anus is absent. A 15 day old male calf was examined and found to have distension of the abdomen and no anal opening, indicating atresia ani. Under epidural anesthesia, a circular incision was made around the bulge of the anus. Liquid feces came out immediately and simple interrupted sutures were used to create a permanent anal orifice. Post-operatively, antibiotics and anti-inflammatory injections were administered for 5 days. Vaseline was advised to be applied in the rectum twice daily for 25-30 days to maintain patency of the new opening.
