Abstract
Liver biopsy at the laparotomy and right omentopexy were conducted in 40 cows with displaced abomasum. Six cases of poor prognosis showed serious clinical signs and fatty infiltration in the liver, and 34 cases of good prognosis were divided into 5 classes of liver fatty infiltration: severe (11 cases), medium (7 cases), mild (8 cases), normal (5 cases) and others (3 cases). The cases of poor prognosis showed higher levels of the hematocrit and ALP than recovered cases with severe liver fatty degeneration as well as higher levels of hematocrit, total bilirubin, GOT, LDH, ALP and ketonuria than those with medium or lower degree of liver fatty degeneration. These results indicated that most cows with displaced abomasum were found to have fatty infiltration of the liver and that the cases of poor prognosis had more serious fatty infiltra tion of the liver. In cases with serious fatty infiltration of the liver, higher levels of the hematocrit and ALP might be indicative of poor prognosis.
