The objective of this study was to carry out epidemiological investigations in cows with displaced abomasum (DA) and to evaluate the recovery of abomasal condition by determining serum pepsinogen and other biochemical values. One hundred twenty-three cows with DA were used in this study. The occurrence rates within 3 weeks after parturition were 80.9% (72/89) for left displacement of the abomasum (LDA) and 65.0% (13/20) for right displacement of the abomasum (RDA), whereas 42.9% (6/14) of abomasal volvulus (AV) occurred after more than 4 weeks. The percentages of dead and disused animal were higher for cows with AV (28.6%) and LDA (23.6%) than for those with RDA (5.0%). There were remarkable increases in nonesterified fatty acids (NEFA) in all cows with DA at operation, whereas hyperglycemia was observed in cows with RDA and AV. The majority of cows with DA showed hypocalcemia and hypochloremia. There were no significant variations in the serum and blood biochemical parameters between free and tie stall cows with DA. The pepsinogen value was markedly decreased in all cows with DA. Pepsinogen values in cows with LDA, RDA and AV at 7-11 days after operation were still lower than the reference value, although most biochemical parameters returned to the normal ranges post-operation. This finding indicates that the mucosa of the abomasum did not recover even at that time.
