Today, the problem of import substitution is particularly acute when providing livestock with feed additives. According to these positions, the domestic feed industry has a significant dependence. Therefore, the development of domestic effective feed additives based on cheap plant raw materials is one of the priority areas of development. At the same time, feed additives should be comprehensive, help to increase the productivity of animals, correct metabolic disorders and prevent stress conditions. The effectiveness of dairy farming directly depends on the provision of animals with balanced nutritious and biologically active components of diets. Moreover, highly productive cows are particularly demanding to these conditions, the effectiveness of the realization of their genetic potential directly depends on the conditions of feeding, maintenance and other stress factors. Poor management in groups of dry-hardy and new-bodied cows, as well as unbalanced diets, leads to various functional disorders, including ketoses. This leads to a decrease in the productivity of cows during the current lactation, a decrease in reproductive capacity, and large financial costs. The article presents research data on the effect of feeding lactating cows with different productivity of a feed additive based on modified zeolite enriched with a complex of protected amino acids and artichoke extract as a hepatoprotector. The use of these additives makes it possible to increase productivity during the current lactation, the amount of milk fat and protein, as well as the average content of the mass fraction of protein in milk while maintaining the quality characteristics of milk in accordance with the requirements of the current regulatory documentation.
