A one-day old madras red male lamb was presented with complaints of depression, anorexic, abdominal straining and lack of defecation. On examination, it was found that the lamb had severe distension of abdomen appeared very dull with sunken eyes and the anal opening was absent. A tentative diagnosis of Type II atresia ani was made and the animal was sedated with 0.1 mg/kg of xylazine administered intramuscularly and under local infiltration with 2% lignocaine. A circular incision was made at the anal scar area and the blind rectum was retracted caudally. The retracted area were fixed to the perineal skin and four stay sutures were placed dorsally, ventrally and bilaterally using 2-0 non-absorbable suture material. Then, the blind end of the rectum was incised to facilitate expulsion of meconium. The animal was maintained under standard postoperative care and had an uneventful recovery.
