Abstract: A four-year-old Jersey crossbred cow was presented to the Veterinary Clinical Complex, Veterinary College and Research Institute, Namakkal, with a five-day history of anorexia, absence of rumination, scanty feces, and reduced milk yield. Clinical examination revealed moderate distension in the upper and middle third of the right abdomen, with tympanic resonance detected over the cranial right paralumbar fossa. The cow exhibited normal temperature but had tachycardia and tachypnea. Rectal examination confirmed a distended abomasum in the right cranial abdomen. Hematological values were within normal limits, while serum biochemistry indicated hypochloremia (71 mEq/L) and hypokalemia (2.9 mEq/L). Transabdominal ultrasonography revealed echogenic fluid ingesta within a well-defined abomasal wall. The Liptak test, performed at the site of tympanic resonance, yielded grayish-brown, watery fluid with a pH of 4.0 and no protozoa, confirming abomasal origin. The cow was treated with Ringer’s lactate, calcium borogluconate, and vitamin supplements. By the second day, normal fecal passage resumed, and the cow achieved complete recovery by the fifth day.
