A clinical case of wheezing associated with rib fractures in a crossbred calf born by natural delivery

Key Points

• To investigate the cause of wheezing in a crossbred calf born via natural delivery with rib fractures.
• A 31-day-old crossbred calf presented with decreased appetite and wheezing. Observations included blood tests and CT scans for rib fractures.
• Direct laryngoscopy was performed to examine the larynx for abnormalities.
• The calf was euthanized for necropsy, confirming tracheal compression by rib fractures.
• CT scans revealed non-union of left ribs 1-4 and right ribs 1-2, causing tracheal narrowing.
• Necropsy confirmed the rib fractures and their association with right lung adhesion but no other abnormalities were found.
• Wheezing was attributed to tracheal pressure from the rib fractures, suggesting potential risks during natural delivery.
