摘要：In the article the effect of different doses of the drug "Lactocormovit" on the milk productivity of cows during the milking period was studied. The animals of the experimental groups had the best milk production. Cows that received the drug "Lactocormovit" in their diet outperformed their peers from the control group in milk yield by 5.6% and 11.4%, respectively. The using of the drug "Lactocormovit" has a positive effect on the chemical composition of milk. According research we found that during the period of experience in cows of the experimental groups increased the amount of milk fat-by 11.45 and 17.71 kg and protein-by 4.84 and 10.18 kg. There is a tendency to improve the physical and chemical indicators of milk.
