This anomaly is defined as complete absence of the part of extremities and different forms were explained for hemimelia. Adactyly is an alternative name for transverse hemimelia and is a rare disorder in the most of animal species. A two months old male lamb with normal vital signs was referred to clinic due to both hind limbs shortness and absence of hooves from the birth day. Clinical and radiological examinations were performed and partial hemimelia was confirmed radiographically in both hind limbs. In left hind limb, total absence of the toe indicated presence of adactyly in this limb. No other congenital deformities were diagnosed in skeletal system based on clinical and radiological examinations. According to our knowledge, this is the first report of such rare conditions in a lamb. Clinical findings and radiological signs of this rare anomaly in a lamb were described in this report.
