MORPHOLOGICAL AND BIOCHEMICAL PARAMETERS OF COWS' BLOOD IN THE COURSE OF RESTORATION OF ESTROUS CYCLE BY USING BIOGENIC MEDICINAL PRODUCT
One of the challenges that intensive dairy farming faces is symptomatic infertility of cows, which is most often caused, by functional disorders of the animals' ovaries. In order to improve reproductive ability of cows, it is necessary to carry out activities aimed at the improvement of metabolic processes in the animal body using biologically active products enhancing the overall resistance of animals at various stages of reproductive cycle. Biologically active products include tissue preparations that are used as additional and independent therapeutic agents; such preparations enhance the animals' metabolism, facilitate energy processes and vital functions of the body, increase the resistance of the body to pathogenic factors, improve regenerative properties, as well as secretory and motor activity of gastrointestinal and intestinal tracts, cardiovascular activity, and blood indicators. In this regard the effect of a new biogenic medicinal product on morphological and biochemical parameters of cows' blood was studied, and the effectiveness of its use for the purpose of restoration of estrous cycle in animals was assessed. The research showed that subcutaneous injections with said biogenic product at a dose of 20 ml at 14-day intervals increased the total hemoglobin in the blood of cows by 9.6-29.7 % and the number of red blood cells by 30.8-39.2 %, respectively, whereas the number of white blood cells increased by 11.3-36.7 %, and albumin in the blood serum increased by 31.3 %; the amount of potassium and magnesium in the blood serum normalized, the Ca : P ratio was 1.23-1.22-1.17: 1 as compared to the initial values. Regular estrous cycle was restored in 93.3 % of the cows of the total number of the animals used in the experiment, 89.3 % of which were successfully inseminated, and 53.6 % were inseminated in their first estrus.
