Megaesophagus in a calf

Abstract

A two week old male Holstein calf was presented with complaints of regurgitation immediately after feeding or drinking milk or water. A barium swallow was performed and demonstrated dilatation of terminal portion of thoracic esophagus, establishing a diagnosis of megaesophagus. At necropsy, esophagus was found to be dilated due to obstruction by a cloth leading to feed accumulation at the entrance of the rumen.
