Abstract :
Congenital anomalies of brachial arches, calluses and grooves have not been previously reported in Iranian sheep. These defects may be due to infectious agents, toxins or genetic abnormalities. This report presents a unilateral brachial cleft in a lamb. The lamb weighed 2.0 kg to 2.5 kg, which is less than the expected normal weight of 3.5 kg, below which survival is risky. The lamb had an oral fistula, one-sided below the ear on the left side. After swallowing food, some of the food was removed from this fistula. In the lower part, which was similar to the jaw and the area of the lower mouth, there were 4 undeveloped teeth with a soft consistency. This fistula was completely closed with reconstructive surgery, taking a flap from inside the pharynx, removing the teeth, and cutting the tongue-like tissue. After 7 days of antibiotic therapy, the animal recovered completely. The occurrence of various congenital anomalies such as cleft palate in the other lambs suggests a genetic origin.
