Prognostic indicators in cattle with right-sided displacement of the abomasum and abomasal volvulus]

The records of 106 cases of right-sided displacement of the abomasum (RDA) and abomasal volvulus (AV) were reviewed. Pre- and postoperative heart rate (> or = 90 BPM), serum BUN (> or = 10 mmol/L), potassium (< or = 3.3 mmol/L) and chloride (< or = 85 mmol/L) were the best indicators for a non-productive outcome. High gamma-GT activity can be used as a preoperative indicator to differentiate AV from RDA. The overall rate of return to a productive life was 74% (81.2% of RDA cases and 67.3% of AV cases).
