Effectiveness of feed additives based on humic substances in the ration of highly productive cows

The article studies the problem of using a feed additive with humic acid, being a highly effective biologically active substance of natural origin, by the farmer. The level of the cow’s milk yield has been studied after feeding Reasil Humic Health additive based on humic acids on the farm in the Gryazovetskiy District, Vologda Region. The authors have proved that the additive feeding has a positive effect on the production performance of animals (the gross milk yield in the control group has been lower than in the experimental one by 9.62% during 3 months of the experiment).
