Environmentally safe lick briquette Amirasol G(S)-L in the diet of cows of a mountain biogeochemical province of Dagestan Republic

The purpose of research is to study the influence of the environmentally friendly lick briquette Amirasol G(S)-L on the indicators of mineral metabolism in dairy cows of the Caucasian brown breed of the mountainous biogeochemical province of the Republic of Dagestan during the spring-summer period of their maintenance. When using the Amirasol G(S)-L lick briquette in cows’ diets for 90 days, a positive effect on mineral metabolism indicators, milk productivity and milk fat content was noted. At the same time, a significant increase in the concentration of mineral metabolism indicators in the blood of the experimental group was established: Na, Mg, Ca, P, Fe, Zn, Mn, Cu, Co, I, Se, respectively, by 19.02; 35.71; 17.54; 48.91; 20.19; 78.72; 66, 81; 85.47; 81.88; 86.12; 92.67 %, with a decrease in K level by 6.62 % compared to the control group. Over the 90 days of the scientific experiment, milk productivity and milk fat content of cows in the experimental group increased by 6.48 and 2.70 %, respectively, or 0.10 abs. %, compared to the control. Studies have shown that the dynamics of changes in mineral metabolism in the blood of dairy cows is directly dependent on the content of minerals in the diet. The data obtained indicate that the environmentally friendly lick briquette Amirasol G(S)-L has a beneficial effect on the body of dairy cows, increasing the mineral status, milk productivity and milk fat content. The results obtained are recommended for implementation in veterinary and livestock practice of the Republic of Dagestan.
