Ultrasonography of left displaced abomasum in local cattle breed

الملخص EN

The aims of the current study were a definitive diagnosis of left displaced abomasum by using ultrasonography furthermore determination of abomasal position and measurements.

Study includes sixteen local cattle breed, six have anorexia, weakness and drop milk production, on clinical examination there was decrease rumen contractions 3.6 5 minutes, furthermore a pinging sound heard on auscultation of left intercostal spaces there were diagnosed as left displaced abomasum, other ten clinically healthy cows considered as normal control group.

Ultrasonographic imaging was performed for stand nonsedated cows by use 3.5-5 MHz transducer at the ventral midline and in the intercostal spaces 9, 10, 11, and 12 from the left side.

Ultrasonography revealed a left side displaced abomasum to an area between the abdominal wall and the rumen, which appeared as hypoechoic fluid content ventrally and hyperechoic parallel echogenic lines of gas gap dorsally, abomasal folds appear as filiform echogenic lines.

While in healthy cows an abomasum located in the ventral midline and directed mainly to the right side.

In conclusion, ultrasonography as a non-invasive technique could be used as a confirmative diagnosis of left displaced abomasal and help for differential diagnosis of left abomasum displacement a well as can be useful for measurement of abomasum in healthy local breed cattle.
