The economic rationale for the use of experimental energy concentrate "Zeolfet" in the diets of lactating cows

In connection with the intensification of the processing industry in the Russian Federation and the Republic of Tatarstan, there is an increase in its production waste, as well as food products with expiring shelf life. The Strategy Of the government of the Russian Federation "Development of the industry for processing, utilization and neutralization of production waste for the period up to 2030" indicates the need to involve additional resources in secondary circulation, thereby reducing the volume of landfills in order to avoid adverse environmental consequences. Given the fact that they are a reserve of full-fledged vegetable fat and animal protein, it is necessary to explore the possibility of rational use of them as animal feed products. The use of experimental energy concentrate "Zeolfat" in the main diet of lactating cows contributed to an increase in milk productivity with the introduction of 200 g per 1.59 kg or 6,9 %, 400 g per 2.14 kg or 9,2 % and 600 g per 2.07 kg or 8.9% compared to the control. In terms of basic (3.4%) fat content, the increase in milk yield was 1,92 kg or 8,1 %; 3,24 kg or 13,7 %, 3.38 kg or 14,3 % respectively compared to the control. The economic effect of the use of experimental energy concentrate "Zeolfat" in the amount of 200; 400 and 600 g per cow per day was 44.2; 72.1 and 67.9 rubles., and the economic efficiency of 1 RUB. additional costs-2.83; 4.51 and 5.53 rubles., respectively.
