Ultrasonographic findings in cows with left and right displacement of abomasum

The purpose of this study was to determine the position appearance of the abomasurn of 20 displace of left and 15 right by ultrasonograhy. Thus, this investigation was also carried out to determine the clinical features of abomasal displacement. The hair was clipped over the from 11th-12th intercostal spaces on the left side and the area was examined ventrally to dorsally with 3.5 MHz and 5MHz transducer held ventra-cranial to the ribs. The similar procedure has been done for right side. After than, the displace abomasum could be visualised from both sides either left or right flanks, The abomasum could be clearly differentiated from adjacent organs because of its contents, which appeared as a heterogeneous moderately echogenic structure with echogenic stippling, However, the wall of the abomasum appeared it at all as a narrow echogenic line. Parts of the abomasal folds were visible occasionally as echogenic structures within the abomasum. Slow movement of the feed in the abomasum was also often visualised. This study shows that ultrasonography is a valuable supplementary technique for the assessment of the left and right displacement of abomasum.
