First branchial arch syndrome in a calf

A calf with two and a half months of age suffering from anomalous face parts exhibited unilateral features of ‘first branchial arch syndrome' or ‘Treacher Collins syndrome’ with symptoms of deviation of the muzzle to left side, tongue to the left and absence of prominence of cheek on left side left ear displacement and abnormal dentition of right side. Congenital anomalies occur as a result of genetic or environment reasons or due to a combination of both. Although not much was known about the etiology, some cases were thought to be inherited due to autosomal recessive gene, with a higher incidence in farms where in¬breeding was practiced.
