The purpose of the present case report was to describe the clinical, laboratory and surgical findings of jejunum intussusception in a five-month old male calf. In this clinical case history, anorexia and lack of defecation for three days were learned from the owner. After clinical and laboratory examination the calf was referred to the Surgery Clinic. A leftflank laparotomy was performed. Intestines were examined for pathologic situation changes. During examination, solid consistency intestine segment was palpated at slight right of the ventral line. During macroscopic examination, invaginated intestine segment was detected as jejunum. Invaginated parts of intestine were edematous, cyanotic and fibrous adhesive, resection and end-to-end anastomosis were performed. The calf discharged was followed by owner. In conclusion, intussusceptions are rarely seen in five month old calves. Its diagnosis could be made by experimental laparotomy and intestine intussusceptions treated with routine surgical interventions in this period.
