Eight Japanese black calves (14‐65 days old) with severe respiration insufficiency due to tracheal stenosis by rib fractures at the calving were brought to Kagoshima University Veterinary Teaching Hospital. At the first visit (NOSAI), all calves had common symptoms of coughing and wheezing sounds. All calves were towed at the time of calving. In x-ray and computed-tomography (CT) examinations, the 1st to 6th right and/or left ribs were fractured and tracheal stenosis was observed. Surgical treatment was conducted in all cases to remove the 1st to 3rd fractured ribs on one side that compressed the trachea. The respiratory condition of all calves improved from the day after surgical relocation and had completely reversed by the 14th postoperative day. From the above, CT examination was found to be useful for diagnosing tracheal stenosis due to rib fracture while removing the fractured ribs on one side is effective surgical treatment.
