Seventy one dairy cattle Iranian Holstein-Firisian breed, with left abomasal displacement were surgically treated by using right and left flank omentopexy and abomasopexy. The LDA was diagnosed on min 4 days and max 30 days post partum. Different surgical techniques are used in Iran for correction of displaced abomasums but the mostly done standing in right and left flank approach. Only one-type suture materials were used to close abdominal wall and skin.Follow up information was obtained, at regular intervals, from two hours through three months. Starting to feed intake, defecation, rumen contraction, appearance of the hair growth on the operation site, milk production, reproductive performance, surgical complication were obtained for each animal. Our results suggest performance for a right flank omentopexy in cattle with displaced abomasums is better.
