STUDYING THE INCREASE AND CAPABILITY OF NUTRITIONAL SUBSTANCES OF RATION OF LACTIVE COWS DURING ADHESORBENT AND ANTIOXIDANT FAILING

For successful denitrification in the body of dairy cattle in zootechnical practice are widely used feed additives with adsorption and antioxidant properties, which, linking nitrates and nitrites in the digestive system, are able to effectively eliminate these toxic compounds in the body. The aim of the research was to study the effect of the adsorbent ekosil and the antioxidant Hadox on the digestibility and digestibility of the nutrients of the diet of lactating cows with a subtoxic dose of nitrates in feed. This article presents the results of studies showing that to increase the milk productivity of dairy cows in diets with a subtoxic dose of nitrates, it is advisable to include ecoosil adsorbent in a dose of 4 kg / ton of feed and an antioxidant Hadox dose of 125 g / ton of feed. It was established that joint approved drugs contributed to the intensification of the processes of digestive metabolism by optimizing the denitrification reaction. This resulted in a significant (P <0.05) increase in dairy cattle 3 of the experimental group versus a control group of dry matter digestibility by 3.28, organic matter by 3.22 %, crude protein by 3.52 %, crude fiber - by 3.07 % and BEV - by 3.25 %. Due to better denitrification under the joint effect of Ecosil and Hadox preparations in animals 3 of the experimental group, the digestibility of raw protein in the ration was optimized, which, against the control group, showed a significant (P <0.05) increase in the amount of nitrogen excreted in milk by 9.34 % and daily the deposition of this element in the body - by 51.43 %. Due to the synergism of the action of the adsorbent and antioxidant in milk of dairy cattle 3 of the experimental group, during the day, there was a significant (P <0.05) more calcium and phosphorus or it was postponed during the same time in the body more of these macronutrients than in the control.
