The effect of the feed additive based on humic acids "Reasil® Humic Vet" on the body of lactating cows has been studied. It has been shown that in the process of lactation, the intensity of metabolic processes increases, as evidenced by the blood counts of cows in the experimental group that were fed with "Reasil® Humic Vet". The content of hemoglobin was higher by 5.5%, erythrocytes - by 6.6%, alkaline reserve - by 5.2% (P <0.05). Animals make better use of dietary nutrients, which are efficiently converted into products. The coefficient of constancy of lactation in cows of the experimental group was 85.4, which is 3.6 points higher than in the control. The feed additive had a positive effect on the prevention of inflammatory processes in the udder of dairy cows. In the experimental group of four cows with mastitis, three of them were recovered. It has been established that the optimal dosage of humic acids in the diets of lactating cows is 1.5 ml of 10% Reasil® Humic Vet solution per 10 kg of live weight.
