Abstract. Complete and balanced feeding, in terms of both nutrients and macro-microelement composition is the main task in increasing animal productivity. The purpose of the study was to determine the effect of feed additives Plexomin Zn 29 and Plexomin Se 2000, containing organic zinc and selenium, on the stressful state of the body of bulls, studying them according to productive and hematological indicators. The scientific experiment was carried out on Black Spotted bulls; for this purpose, two groups (control and experimental) were formed with 20 heads in each, with an average live weight of 328.8-329.3 kg. The bulls of the experimental group received a daily diet supplement in the amount of 460 mg, which contained Zn (zinc) and Se (selenium) in organic form. For a comparative assessment of the metabolic processes occurring in the body of bull calves that consumed a feed additive with and without the diet, morphological and biochemical blood tests were carried out. The research results indicate a positive effect of the studied feed additives on productive and hematological parameters. It was found that live weight of bulls in the experimental group at the end of the experiment was 2.5% greater than in the control. Intergroup morphological and biochemical blood parameters of experimental bulls had some differences, but were within the physiological standard.

Keywords: bulls, feeding, feed additive, zinc, selenium, hematological parameters
