INFLUENCE OF HEPATOPROTEC-TOR "HEPALAN" ON DAIRY PRODUCTIVITY IN HEIFERS

Abstract

In the present work, the influence of the hepatoprotector “Hepalan” on the milk production of heifers is analyzed. The study revealed an increase in milk yield in first-calf heifers who were asked the test drug in all three months of the milking period in relation to first-calf heifers kept on a common farm ration. So, for one feed head from the experimental group, milk was received in the first month of lactation by 1.25% more than in the control group (26.91 kg / head of milk in the control group compared to 27.25 kg / head of milk in the experimental group ) In the second month of lactation, 3.97% (29.78 kg / head of milk in the control group versus 31.01 kg / head of milk in the experimental group). For the third month of lactation, the difference in milk yields between groups of animals reached 10.7%, in favor of the experimental one (32.6 kg / head of milk in the control group versus 36.5 kg / head of milk in the experimental group). No visible effect of this hepatoprotector on the protein and fat content in the milk of the heifers studied was found. There was only a slight increase in these indicators in animals from the experimental group. As a result of this study, it was found that the inclusion of the hepatoprotector “Hepalan” in the composition of the current diet provided an improvement in the physiological state of animals, against which a marked increase in milk productivity was observed by the end of the milking period. Thus, we recommend the Hepalan dietary supplement for successful use in the feeding of cows in industrial production.
