| Abstract | ||||
| Eleven dairy cattle with left abomasal displacement were investigated. Thorough clinical examination was performed. Ultrasonography of left side abdomen from the 9th to 12th intercostal space (ICS) and ventral abdomen was applied on standing position using 3.5-5 MHz transducer. Blood, urine and ruminal samples were collected from the affected cattle for laboratory evaluation. Left flank laparotomy was applied on 8 cows to confirm and treat the cases while the other 3 cases had bad prognosis. Clinically, the general condition and milk production were altered, feces was scanty and either soft or hard, ruminal motility was detectable but with lower number and strength and ping sound was detected over the 9th to 12th ICS by simultaneous percussion and auscultation. Ultra-sonographically, the displaced abomasum was clearly visible between the left 10th and 12th ICS in all cows. Gas cap with reverberation artifact appeared at left dorsal region while the hypoechoic content of abomasum appeared at left ventral region. Echogenic bands of abomasal folds were observed in 4 cows. Pylorus was detected at left Paramedian at area extended between umbilicus and left costal arch under the 9th to 11th ICS. Laboratory findings revealed mild metabolic alkalosis, hypokalemia, hypocalcaemia, mild decrease ruminal PH, increase in chloride content, Prolonged time of methylene blue reduction time and ketonuria. In conclusion, ultrasonography not only considered as an easy, fast and accurate tool for diagnosis of LDA in cows but also it is a good decision tool. | ||||
