We examined the therapeutic gain of ventrotomy for abomasal displacement in four Holstein beef cattle. The method of operation was by paramedian incision. Three cattle had left displaced abomasa (LDA) and the other had a right displaced abomasum (RDA) . The clinical signs and surgical findings were recorded for the treatment period. Dry matter intake (DMD) was measured every day, while body weight and daily gain (DG) were measured every four weeks. Upon physical examination, all cases showed heavy inappetance. Percussion of the abdominal area on the left or right side produced a metaric resonance. At the time of the operation, 2 LDA showed distention of the abomasum, and one LDA and the RDA had relaxed abomasum. After the operation, the clinical conditions improved, in turn, DMI and body weight increased. From the results of carcasses judging, carcasses weights and rib eye areas tended to be small, but yield criterias were excellent. From these results, ventrotomy by paramedian incision was considered effective to the abomasal displacement in Holstein beef cattle.
