Obstructed Airway

Esophageal obstruction due to a trichobezoar in a cow

A 4-year-old, 6-month pregnant, Angus cow was presented to our clinic with a history of acute onset of severe bloat, respiratory distress, and inability to swallow. The owner had tried unsuccessfully to pass a stomach tube and reported that the tube was being obstructed just beyond the throat. Clinical examination of the cow revealed that the temperature was normal, the heart rate was 96 beats/min, and the respiratory rate was 60 breaths/min. The cow had severe abdominal distention and coughed at regular intervals. Copious amounts of saliva were expelled during these coughing episodes.

THE USE OF THYGESEN'S PROBANG IN THE TREATMENT OF BOVINE ESOPHAGEAL OBSTRUCTION DUE TO SUGAR BEETS

Cattle eat many things that cause esophageal obstruction, but in the authors' practice, sugar beets are the most common. Sugar beets and tops are very palatable to cattle and are readily consumed. The tops and the small beets (under 3" diameter) are being used increasingly either as silage or by allowing cattle to graze on windrows of beets remaining in the field after harvest. Obstruction may be caused by small beets, or by portions cut from beets of all sizes during harvesting.
