Development in Romania in the last 15 years, the new dairy farms with high production Holstein cows, usually the cows are exposed to a productive enforcement by feeding them with TMR (total mixed ration) with high ratios concentrates, leads to occurrence of other conditions between them being left displacement of abomasum(LDA). This condition usually occurs as early as 45 days post partum, associated with other intercurrent diseases like: retained placenta, metritis, mastitis, ketosis. The most common clinical signs observed on 11 cows in the study were: sudden decrease in milk production, off feed, udder like sponge consistence, vital functions range in normal limits, dehydration being observed only in last stage. Positive diagnosis was established by simultaneous percussion and auscultation in the left flank, where the “ping” sound appears. Surgical correction can be performed by different surgical procedures, in the present study we performed surgical correction by right pyloroomentopexy.
