【 摘 要 】

It has been established that the level of blood parameters in the body of sheep is not always stable and often depends on the breed, sex, their physiological state, the level of productivity, feeding and housing conditions. Among the factors that determine the optimal sheep nutritional level, not the last place is occupied by their provision with a sufficient amount of essential amino acids, especially lysine, methionine, cystine, and vitamins, given their physiological importance for the animal body. The overwhelming amount of them is able to be synthesized in the sheep rumen with the help of microorganisms of the gastrointestinal tract, however, some of them are irreplaceable, that is, those whose balance must be replenished through feed rations. The article describes the use of the vitamin-amino acid complex "Аlphabet for Animals" in sheep, containing a complex of fat-and water-soluble vitamins, as well as amino acids, which contribute to the normalization of metabolism in the body of small ruminants, increase its resistance, have a positive effect on productivity, safety and reproductive animals functions. During the research, the effect of this feed additive on hemocytopoiesis and the exchange of essential micronutrients in ewes were studied. After a double use of the additive, an increase in the processes of erythrocytopoiesis was established, as evidenced by an increase in the number of blood erythrocytes by 21.2% and the hemoglobin content by 11.2%, stabilization of the size and degree of saturation of erythrocytes with hemoglobin, as evidenced by a decrease in MCH and MCV indices. There were no significant changes in the content of essential micronutrients in the blood serum of sheep under the influence of the "Alphabet for Animals", and a slight increase of zinc content in the blood was noted in sheep after the second injection of the drug. At the same time, in the blood of experimental animals group a significant increase the iron content on average up to 129.5±7.33 μg/100 ml (p <0.05) was established, and the number of animals with a low amount of blood iron was only 12.5 %. The number of leukocytes in the sheep blood of both groups was within the normal range and during the second and third blood tests did not change significantly.
