Feeding lactating dairy cows of the Simmental breed using the collection of herbs with Тhyмus bituminosus Klok, Achillea millefolium L., Polygonum aviculare L., Galium verum L, Chamerion angustifolium L., Sanguisórba officinális, Stellaria media L. and Amaranthus retraflexus L. contributed to a better digestibility and nutrient utilization of diets. A high level of digestibility by cows experimental compared to the control group is set with respect to the dry and organic matter of 2.0% and a crude protein 1.4 %. When using the collection of herbs, there was an increase in the antioxidant status of erythrocyte cells in blood of dairy cows as expressed in the increasing content of low molecular weight antioxidants in blood cells by 1.4 times in reducing the intensity of lipid peroxidation of erythrocyte membranes in 1,2 times, in comparison with the control values. The use of the collection of herbal increases milk yield of cows of the experimental group by 7.4 %, increases by the 16.2 % yield of milk fat and the protein content of 10.7 % in milk of dairy cows compared to the control group
