Congenital Malformations in ruminants and its surgical management

A survey was undertaken to analyse the congenital malformation in ruminants reported to the Large Animal Surgery Out Patient Unit of Madras Veterinary College Teaching Hospital from April 2005 to March 2009. A total of 26 cases of congenital malformation (including atresia ani -10, dermoid cyst - 8, contracted tendon - 7 and urethral diverticulum - 1) were reviewed in this study. Incidence of atresia ani was more in male calves, dermoid cyst and contracted tendon were more common in females. Animal with congenital malformation, surgical correction could be attempted, but breeding of these animals should be avoided.
