EXPERIMENTAL ENERGY CONCENTRATE "ZEOLFAT" IN THE DIETS OF LACTATING COWS

Abstract

The introduction of the experimental energy concentrate "Zeolfat" in doses of 200, 400 and 600 g/kg per day into the main diet of lactating cows allowed to increase the content of raw fat by 6.69%, 13.38% and 19.91%; exchange energy by 1.46; 2.92 and 4.37%, respectively. As a result, the increase in average daily milk yields in terms of (3.4%) basic fat content was 8.1% in the I group with the introduction of 200 g of concentrate, in the II (400 g) -13.7, in the III (600 g) - 14.3% compared to the control. A positive effect on the biochemical parameters of blood serum characterizing carbohydrate-lipid and mineral metabolism in the body was established. Economic efficiency per 1 RUB of additional costs in the experimental groups was 2.83-5.53 RUB, respectively.
