Plasma lipoproteins and fatty liver in dairy cows.
Dairy cows were classified on the basis of a histological study after a hepatic biopsy conducted in the second week post partum (mild fatty liver, moderate fatty liver, severe fatty liver). Plasma lipoproteins were separated into various density classes by repeated ultracentrifugation. The results indicate that the beginning of lactation is associated with a low concentration of the 1.006 to 1.063 g ml-1 lipoprotein fraction. The lowest concentrations occurred in cows with severe steatosis or during the evolution of moderate steatosis.
