This study was carried out to investigate the morbidity of fatty liver in cattle at the abattoir and on the farm, and to cytodiagnose fatty liver in cattle by fine needle aspiration biopsy. Incidence rates of fatty liver in cattle, detected macroscopically or based on hepatic lipid content by buoyancy, were 0.30% in Korean native cows, 4.70% in dairy cows, and 0.15% in dairy bull. Fatty liver was enlarged, swollen with round edges, light weight, and pale to yellow-orange color, but its color was not always correlated to the severity of fatty liver. The findings of fat infiltration of the hepatic lobule were large droplets around central vein, fine droplets in the periphery, and fat infiltration in the perivascular region execpt for most of normal liver and severe fatty liver. The sensitivty, specificity, and accuracy of cytological finding compared with hepatic lipid content by buoyancy were 94.4%, 95.2%, and 94.9% in normal cases, 64.3%, 100%, and 87.2% in mild cases, 100%, 83.3%, and 87.2% in moderate cases, and 100%, 100%, and 100% in sesvere cases, respectively. Cytological findings were well correlated with histological findings. Complications of fine needle aspiration biopsy were not recognized clinically. Consequently, the cytodiagnosis by fine needle aspiration biopsy is simple, rapid, safe, and economical method compared with histological techniques in the diagnosis of fatty liver in cattle. |
