Abstract :The article deals with the results of the study of efficiency of feed additives in the form of a bolus ("Megabolus"). We established decrease in pathology of the reproductive system in comparison with the control by 9.8%, artificial insemination index in cows of the experimental group (EG) decreased by 11.1%. Components of the "Megabolus" increased of amount of albumin in the EG of cows up to 32.2±0.9 g/l; in the control up to - 30.2 g/l. Indicators of blood in the EG confirm the efficiency of boluses: increase the absorption of manganese is up to 25.6%, carotene - 16.2%.Keywords : dairy cows, feed additive, bolus, reproductive function, blood
