BIOCHEMICAL FEATURES OF THE FUNCTIONAL STATE OF THE LIVER OF COWS FEEDING THEM VERMICULITE
Studied the biochemical features of the functional liver of dairy cows when feeding them mineral supplements vermiculite. The use of vermiculite, in the diet of cows, due to its ion-exchange and sorption properties and had a positive impact on the performance of the functional state of the liver, as evidenced by a decrease in the activity of AST and de Ritis coefficient in the experimental group by 9.6 and 15.4% and an increase in ALT activity in all groups by 9.27-26.8%. Functional state of the liver in cows of the experimental groups associated with cholesterol, the content of which remains within the physiological norm. A significant decrease in the blood of animals of the first experimental group of direct bilirubin indicates the effective utilization of bilirubin and its release into the
