The positive effect of extruded lupine grain in the composition of compound feed on the increase in milk productivity of cows was established, which made it possible to receive an additional 112 kg of milk and profit from the sale of milk — 1635 rubles on average per 1 head for the entire study period (75 days). An improvement in the qualitative composition of milk was revealed: the mass fraction of fat in cows in the experimental group was increased to 4.13%, compared to 3.87% in the control group; the mass fraction of protein in cows in the experimental group was 3.38%, while in cows in the control it was 3.27%.
