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%.
