In realization of the genetic productivity potential of different species of farm animals, an important place is given to full feeding. Insufficient supply of farm animals with individual vitamins has negative impact on the activity of the relevant enzyme systems, hormonal status, metabolism of nutrients, the state of the natural resistance of the various organs and organ systems, the processes of adaptation and productivity level. Numerical searches have shown that farm animals need in different vitamins depends on the type, age, sex, physiological state, the season, the level of productivity and others. According to some reports ruminants have been providing with water-soluble B vitamins by their rumen microbial synthesis accordingly it was recommended to rations setting for cattle, sheep and goats, along with nutrients and minerals only by carotene and vitamins D and E. Specific features of the effect of different doses of complex B vitamins (thiamine hydrochloride, riboflavin, niacin, pyridoxine hydrochloride, folic acid, ciankobalamin in venous blood) on morphological composition (erythrocytes, leukocytes, platelets, hemoglobin, hematocrit, erythrocyte sedimentation rate) and clinical indicators (heart rate, respiratory rate, type temperature) at the final stage bull fattening. Studies have shown that the addition to the diet of calves for fattening balanced nutrients and minerals and fat-soluble vitamins A, D, E complex of B vitamins (В1, В2, В5, В6, В10, В12) in appropriate doses generally positive effect on erythrocytes, leukocytes, hemoglobin, hematocrit, dose-dependent additionally introduced into the diet of B vitamins (В1, В2, В5, В6, В10, В12). The basis for our dosage of various B vitamins for Bovine experimental groups on fattening is the corresponding percentage of the recommended doses of certain B vitamins for fattening pigs (10 % – D1, 20 % – D2, 40 % – D3, 60 % – D4 group). The biggest change in terms on morphological composition in animals 3rd ((В1 – 0,040; В2 – 0,06; В5 – 1.2; В6 – 0.25; В10 – 0.0030; В12 – 0.0006 mg/kg body weight) and 4th (В1 – 0.070; В2 – 0.10; В5 – 2.0; В6 – 0.40; В10 – 0.0050; В12 – 0.0010 mg/kg body weight) research groups, and smallest – in bull 1st (В1 – 0.015; В2 – 0.03; В5 – 0.5; В6 – 0.10; В10 – 0.0012; В12 – 0.0002 mg/kg body weight) and 2 th (В1 – 0.025; В2 – 0.04; В5 – 0.8; В6 – 0.15; В10 – 0.0020; В12 – 0.0004 mg/kg body weight) research group, which is associated with dose introduced to the diet of calves during the final fattening phase of B vitamins (В1, В2, В5, В6, В10, В12).
