Popis:	The purpose of the work was the correction rumen fermentation in the transition cows to prevent metabolic disorders. For the experiment, two groups of Ukrainian dairy black-and-white breed cows were formed, 10 animals per group. The experiment lasted 3 weeks prepartum and 3 weeks postpartum. Animals received a balanced diet, which consisted of haylage, silage, barley, wheat, corn, soybean meal, salt, mineral and vitamin premix. The first group was the control. To the diet of second group 300 mg of α-tocopherol acetate (0.6 g of Rovimix E-50) and 1 g/kg of dry hop cones per kg of dry matter was added. Before calving, the tested feed additive reduced the concentration of peroxide oxidation products in the cows blood (P
