Abstract. The article presents the results of studying the milk productivity of cattle when using feed additives “Promevit” and “Biatis” in the diet. The purpose of the study is to develop an effective way to increase the milk productivity of cattle by combining the vitamin-mineral additive “Promevit” with the protein-vitamin-mineral concentrate “Biatis” into the diet of animals. The scientific novelty lies in the fact that for the first time in feeding lactating cows, the vitamin-mineral additive “Promevit” was used together with the protein-vitamin-mineral concentrate “Biatis”. Methods. The research was carried out at “Novyy Put’” LLC in the Shali district of the Sverdlovsk region on Holstein cows in the period from 2021 to 2023. To conduct the experiment on the principle of pair-analogues, taking into account age, the level of milk productivity for the previous lactation and the stage of the reproductive cycle, 4 groups of cows of 15 heads each were formed. Milk yield for 305 days of lactation, mass fractions of fat and protein, the content of calcium and phosphorus, dry skimmed milk residue in cows’ milk, density, titratable acidity, and the number of somatic cells were determined using generally accepted research methods. The amount of milk fat and protein was calculated. Results. It was found that the highest values of milk productivity indicators were observed in cows of the 3rd experimental group, which, in addition to the main diet, received 125 g of “Promevit” and 4 g of “Biatis”. The results obtained allow us to recommend them for use in feeding lactating cows both in industrial animal husbandry, as well as in peasant farms and personal subsidiary farms.
