Case report

Intestinal Obstruction in a Steer

Abstract

A 550 lb steer was presented with a history of anorexia, depression, "stiffness", and scant feces. Physical examination revealed a normal rectal temperature, increased heart and respiratory rates and abdominal distension. The initial attempt to examine the steer per rectum was unsuccessful. Laboratory findings were normal except for increased protein in the abdominal fluid. A second examination of the abdomen per rectum revealed a tight, fibrous band extending from the right internal inguinal ring to the pelvic floor, which had entrapped portions of the small intestine. An exploratory laparotomy was done using the right paralumbar fossa approach. The tight fibrous band was found to be a remnant of the vas deferens. The band was exteriorized and cut with scissors. Post-operative recovery was uneventful and the steer was marketed months later at his projected market weight.
