The right displacement of abomasum with ulceration in a calf.

Summary The aim of this case report is to describe the clinical, ultrasonographic, and surgical findings in an 8-week-old female Holstein calf with right abomasal displacement and ulceration. Auscultation/percussion, auscultation/ballottement, and ultrasound examination were used to identify displacement of the abomasum. Right-flank laparotomy was used for repositioning of the displaced abomasum. The abomasum was greatly distended between the rumen and right body wall. Approximately 7 L of abomasal content was discharged from the abomasum. A few ulcerative areas in the mucosal surface of abomasum were observed. After surgery, antimicrobial and antiulcerative therapy were given. The calf discharged was followed with telephonically. As a result, right displacement of the abomasum is very rarely seen in calves. Right flank laparotomy gives good result in calves with right displaced abomasum, and ultrasound examination helps to distinguish right displaced abomasum from other metabolic disorders of the digestive tract in calves.
