Abstract
Five cases of cleft lips (four males and one female) and one case of cheilognathoschisis in Japanese shorthorn cattle (0-10-months-old) were examined. There were no disturbances in appetite or on physical examination, except that case No.3 hadcheilognathoschisis. Case No.3 had difficulty suckling. No.3 died and all the other animals were sold in November 1996. Necropsy of case No.3 revealed craniofacial skeletal abnormalities. The cause of this disease was not apparent, but inbreeding may be a possible cause.
