The article presents the data obtained in the scientific-economic experience on lactating cows of black-motley breed fed as a basic diet with green mass of gramineous and herbal meadows, meadow fescue, the fodder contaning oat bran (50%), wheat bran (50%), and sodium salt. The sample group of animals received the same feed and additionally vetch-oat mixture of 1.72 MJ of metabolizable energy per kg, 18 g of digestible protein, and a high level of fiber of abount 60 g after flowering. For the period of research the analysis of the average daily diet composition has been carried out, as well as the milk productivity and qualitative milk characteristics of dairy cows in summer have been studied.
