| Varieties of the abdominal cavity diseases of the ruminants make an directly effects on the production status and lactation volume,and it also has a significant impact on the farming income. Many celiac diseases, such as fatty liver, cholecystitis and abomasum displacement, have a high incidence. In foreign, studies have shown that ultrasonic can be used to the cow liver, gall bladder, spleen, stomach, kidney and other quick and real-time detection of abdominal organs, which is conducive to the early diagnosis, prevention and treatment of diseases. But at present, domestic abdominal viscera ultrasonic detection technology research and its clinical application are still less, which is to restrict the early diagnosis of abdominal viscera disease and prevention in cows.In this study, a 3.0 MHz transducer was used to scan the 7th to 12 th intercostal spaces and the arch trailing edge of the 13 th rib on the right side of cows. In the ultrasonic image, the liver echo intensity appeared weak, light homogeneous and fine and uniform brightness. An irregular cuneate, the head of the liver ends back on the 7th floor oblique upward, 13 rib arch trailing edge detection to the end.In the 7th ribs of the healthy cows, the mean distance of the up edge of the liver from the midline of the back was 65.89±3.88 cm,and the down edge of the liver from the midline of the back was 82.78±7.32 cm. In the 13 th ribs, the mean distance of the up edge of the liver from the midline of the back was 20.3±1.5 cm, and the down edge of the liver from the midline of the back was 35.66±4.58 cm. The gallbladder can be probed found between the 9th to 11 th ribs, and gallbladder wall rendering of medium echo intensity, content to present anechoic liquid dark space, the boundary clear and tidy. In different ribs, measuring range is 61.57±7.21 cm~67.67±2.08 cm.In the 12 th and trailing edge of the13 th ribs, the right kidney can be detected and its detection range was 27.5±4.28 cm~29.22±3.07 cm,and the renal pelvis was elliptic cross section structure. The renal medulla echo intensity appeared weak, with poor quality. The echo intensity is slightly lower than the liver kidney cortex, light thin, relatively dense. However, the left kidney through the body surface is difficult to probe.The abomasums of the 30 healthy cows are located in the 8th to the 11 th ribs. The wall of abomasum appeared as a weak echo of fine line, and the stratification is not obvious, difficult to distinguish. The contents of the abomasum were overall performed with mixed echo, occasionally weak echo waves of the fold structure. In the 8th ribs of the healthy cows, the mean distance of the up edge of the abomasum from the midline of the back was 97±3.03 cm, and the down edge of the abomasum from the midline of the back was 113.2±9.8 cm In the 11 th ribs, the mean distance of the up edge of the abomasum from the midline of the back was 97.8±0.9 cm,and the down edge of the abomasum from the midline of the back was 106.8±7.89 cm.Normally, a 3.0 MHz transducer was used to scan the 7th to 12 th intercostal spaces on the left side to scan the spleen. The spleens substance present weak echo intensity, echo just above the liver, homogeneous, thin spot, and the spleen parenchyma inclusions appear oval or long, then thin dark echo areas are of different sizes of the spleen blood vessels. The spleen is the head back after lateral ventral a banded structure, head side on the 7th floor to the caudal oblique upward, both ends obtuse. In the 7th ribs of the healthy cows, the mean distance of the up edge of the spleen from the midline of the back was 69.25±5.03 cm, and the down edge of the spleen from the midline of the back was 83.62±4.9 cm, in the 12 th ribs, the mean distance of the up edge of the spleen from the midline of the back was 12.5±1.9 cm, and the down edge of the spleen from the midline of the back was 21.4±2.99 cm.In practice, a group of classic right abomasum displacement(RDA) inholstein cattles were found. Compared with the healthy cows, the abomasums of the 5 RDA cows were larger and embedded in the liver and the wall of the abomasums, located significantly closer to the costal arch and the midline of the dorsum. The structure characteristics of abomasum plica can be clearly analysed. Finally, the diagnosis of open surgery was confirmed in all. In addition, abomasum accumulation of gas in the reverberation artifacts,appeared with abomasum displacement, making originally can not be detected, and the vane of the omasum also can be used as a typical ultrasonographic characteristics of abomasum displacement to the right. The abomasum of the head of cattle, and really the typical image of the abomasum was got in the 13 th rib trailing edge back side of the 3 cattles in the 5 RDA cattles, and the cattle of the 13 floor near the trailing edge and 12 rib dorsal position, and the abomasum and intestinal canal of the adjacent interface. The reverberation artifacts and abomasum fold were found near the location of the dorsal probe in 4 cattles.On the other hand, the tipical images of the reticulum of the 5 RDA cattles were found between the 8th and 9th rib near the bottom of the abdomen.Because of the five head of cattle to varying degrees of abomasum displacement so not all the cattle are the characteristics of the image, check found after laparotomy exploration to the intestinal canal and artifact cows abomasum displacement degree is more serious, abomasum caudal rib has been extended to 13 trailing edge location, the degree of displacement and the other 2 head relatively mild, true stomach in the abdomen on the right side of the midline position, has not been five head of cattle in the right turn.In this paper, 30 healthy cows were on an ultrasound examination of the left and the right side of the abdominal wall and the bottom surface. So the healthy cows’ liver, gall bladder, kidney,abomasum, spleen, characteristics of abdominal organs such as the sonographic findings were determined by recording and analysis by using ultrasonic surface probe. Then, the normal cows abdominal ultrasonographic features of main organs to abnormal ultrasonography of cows‘ appearance is made accurate judgment. In the future, reliable method and the implementation of celiac disease ultrasound examination diagnosis can be provided. |
