In a female black and white coloured German Holstein calf bilateral anotia and impaired vision was observed. This congenital anomaly is very seldomly seen in cattle. The clinical examination revealed no further anomalies. The test on a BVDV infection was negative. No other affected calves could be detected by examining the relatives.
