In order to increase the productivity of dairy cows and maintain their health, the search for complex food additives with multifactorial positive properties is continuously carried out. A scientific and economic experiment of a new food additive based on needles developed by the technical and research centre “Khiminvest” has been conducted. The experiment has been conducted by the method of groups-analogues on highly productive cows. Food additive based on pine needles has had a positive impact on milk productivity, milk protein content, carotene and nonspecific immunity, as well as individual indicators of reproduction. The effectiveness of the additive has been 29.50 rubles per 1 cow a day.
