Ultrasonography of the omasum in 30 Saanen goats

This report describes the findings of ultrasonographic examination of the abomasum in 30 goats. A 5.0 MHz linear transducer was used to scan the left and right paramedian regions, the linea alba and the right abdominal wall of standing goats. The abomasum appeared as a heterogeneous, moderately echogenic structure with echogenic stippling. The abomasum could be seen from the linea alba in all the goats. The abomasal folds were easily identified in 19 goats and appeared as prominent echogenic bands. The cranial visible limit of the abomasum was -0.3 [2.34]cm from the xyphoid, and the caudal limit was 10.3 [3.08]cm caudal to the xyphoid. The visible length of the abomasum was 10.7 [1.96]cm and the maximum width 30.2 [7.43]cm. The height of the abomasum was 6.7 [1.79]cm.
