Evaluation of the effectiveness of the effect of feed based on waste from sugar processing and yeast production on the dairy productivity of cows

By-products of processing of various industries at an optimal level of their introduction into the diet of farm animals can increase the productivity of farm animals, and can also have a positive effect on metabolic processes in the body. In this regard, the introduction of different levels of sugar processing products and yeast production of domestic production into the diet of lactating cows during the milking period in the amount of 4.11 and 8.22 % in the composition of compound feed was considered, while reducing the proportion of sunflower meal, barley grain, beet pulp and an increase in corn grain. It has been established that the introduction of 8.22 % of the Vinassa feed product in the compound feed increases the uniformity of the fully mixed diet and reduces its separation by animals, which is probably due to its physico-chemical properties. In cows of the second experimental group, during the milking period, an increase in the gross milk yield of 4 % fat content during the milking period by 7.1 % and an increase in the gross milk fat yield by 7.1 % was found (the difference is significant). The introduction of the feed agent “Vinassa” in the amount of 8.22 % in the composition of compound feed during the separation period helps to optimize metabolic processes in the body, as evidenced by the results of a biochemical blood test.
