Observations on Tracheal Collapse in Cattle

Abstract

Tracheal collapse is a condition that has been infrequently reported in cattle but has been well recognized in horses and in coy breeds of dogs. Animals affected with this condition have a tracheal lumen which is reduced in diameter because of a change in the normal architecture in the tracheal rings. Three cases of tracheal collapse were observed at Kansas State University ranging in age from two weeks to four months with the following breeds being involved: Simmental, Limousine, and Maine-Anjou Shorthorn Cross. All calves had
exhibited clinical signs of respirarory difficulty shortly following birth, and the condition was unresponsive co antibiotic therapy, other respirarory supportive drugs, and a tracheoromy.
