Background and Aim: Dairy cattle breeding plays a significant role in providing the population with high-quality, reasonably priced goods. The development of this industry and its effectiveness depends on the proper use of available feed products. Feed additives (FAs), as a rule, should compensate for missing elements in the diet. This study aimed to determine the effect of the FA Vermikom on blood parameters, as well as milk physicochemical and mineral composition and yield in lactating dairy cows. Materials and Methods: A total of 30 Holstein cows, with an average weight of 650±5 kg, were randomly divided into three groups of 10. Over a period of 5 months, each group was fed one of three diets: Mixed main diet without supplements (control), main diet supplemented with 2% Vermikom, and main diet supplemented with 4% Vermikom. Results: Hematological parameters, productivity, and physicochemical and mineral composition of milk from animals provided the FA Vermikom were higher than those of the control group. In the Vermikom groups, the hemoglobin content was higher by 5.75%, calcium by an average of 10.8%, and total protein by 2.5%. The average daily milk yield was also higher by 8.4% than the control group. Regarding the mineral composition of the milk, the content of calcium, phosphorus, and iron exceeded that of the control on average by 2.9%, 3.4%, and 14.8%, respectively. Conclusion: We propose introducing 4% Vermikom into the diet of dairy cows based on the study results. Future research will expand our knowledge regarding cows' needs for all recommended nutrients, thereby improving animal productivity and milk quality. The results obtained contribute to further expanding the food base of animal husbandry in the Republic of Kazakhstan.

Relevance and methodology. Milk production is effective for producers only in case of high productivity of the farmed livestock. In the prime cost of raw milk, feed costs account for over 60%, in connection with which the main task of modern science is the development of additives and preparations that can improve the use of feed by animals, which will ensure an increase in livestock productivity. The research team of OOO Biotrof has created an experimental preparation "Rumit" — a complex of live bacteria based on cultured strains of cellulolytic bacteria of deer rumen. The effectiveness of the enzymeprobiotic supplement was studied in the breeding farms of the SKHPK collective farm "Peredovoy" and JSC "Plemzavod Rodina" of the Vologda region on lactating cows with a productivity of over 8000 kg of milk per lactation. To conduct the experiment by the method of balanced groups for a complex of economically useful traits and genetic potential, a control and experimental group of 10–12 animals each were formed. Experienced groups were fed with the drug "Rumit" 50 g per head per day during the day.Results. For 90 days of the experiment, the total density of ciliates in the contents of the rumen of the experimental groups increased by 155.9–173.0 thousand ops / ml, and the significant difference with the control was 13.5.9–171.7 thousand ops / ml. The emergence of new genera of ciliates was noted: in the agricultural production complex the collective farm "Peredovoy" — Epidinium, in the JSC "Plemzavod Rodina" — Isotricha and Ophryoscolex. The increase in the average daily milk yield in the experimental groups was from 6.3 to 9.0% in the context of enterprises, an increase in the fat content in milk by 0.05–0.07% and protein by 0.03–0.07% was noted. As a result, in the SKHPK collective farm "Peredovoy" in the experimental group, 283 kg of milk of basic fat content were additionally obtained, and in JSC Plemzavod Rodina — 112 kg. In terms of per day from one head, it is possible to receive additional profit when feeding "Rumit" in the amount of 24.50 rubles. up to 120.15 rubles.

Relevance. The problem of infections resistant to antibiotics has led to a complete or partial abandonment of the use of antibiotics in agriculture as growth promoters. To improve the functions of the rumen microflora, digestive processes, increase bioavailability and utilization of nutrients, biologically active substances from various parts of plants are used, in particular phytobiotics contained in coniferous needles and their processing products. Coniferous needles are a by-product of logging and are recycled, which makes their cheap acquisition recommendable for use as a vitamin feed in poultry and livestock farming. The chemical composition of coniferous needles is represented by a wide range of minerals, biologically active organic compounds with high activity that affect the synthesis and action of vitamins and increase the activity of hormones in the body of animals and birds. Coniferous needles are rich in carotenoids, ascorbic acid, B vitamins, alpha-tocopherol, natural phenolic compounds, carboxylic acids, polyphenols, fatty acids and their derivatives. This stimulates the production of endogenous enzymes, immune, antibacterial, anthelmintic activity and antioxidant properties. Digestibility and availability of nutrients in feed are improved. Fresh coniferous needles are widely used in feeding animals, birds, as well as aquaculture in the form of flour, pastes, aqueous infusions, energy supplements — phytoncidal multivitamin preparations.
