This study was conducted to determine the occurrence of atresia ani in bovine calves and to delineate its surgical correction at Veterinary Teaching Hospital, Patuakhali Science and Technology University (PSTU), Bangladesh. A total of 17 congenitally affected calves were examined from September 2014 to February 2015 out of which 12 (4 female calves and 8 male calves) were diagnosed to determine Atresia ani with complete absence of anal opening. The occurrence of Atresia ani in calves was recorded as 70.59% of all other congenital defects found at Veterinary Teaching Hospital, PSTU. It was observed that the occurrence of Atresia ani in males was two times more than females. It was also noticed that cross bred animal (58.33%) was more susceptible to Atresia ani than local breed (41.67%). Surgical correction was found to be the only successful and curative approach for Atresia ani. After conducting low epidural anesthesia a vertical incision of about 2-2.5 cm was made to facilitate anal opening. In some cases the ill/less developed rectum was palpated, grasped and enclosed to the anal opening. Precautions were taken to reduce tissue injury, bleeding and other further complications. Further detail studies are necessary to find out molecular mechanisms of Atresia ani and its socioeconomic significance in livestock sector in Bangladesh
