The production and availability of dairy and meat products of animal husbandry is the most important condition for a healthy diet of the country's population. The solution to the problem lies in the concentration of the industry in the forest zone, which is most favorable for the intensive use of mesophytic herbaceous vegetation, the main food resource for ruminants. The most important advantages of perennial herbaceous vegetation compared to annual vegetation are: productivity, feed quality and high return on anthropogenic costs, resistance to adverse environmental factors, adaptability, longevity, the possibility of permanent cultivation, anti-erosion resistance, reproduction of soil fertility, decarbonization 1–5. When using perennial grasses in the hay-pasture regime, the cost of feed production is 1.5–2.7 times lower compared to annual crops 6; 7, which significantly increases the profitability of production. In general, forage resources, including extensive natural lands, make it possible to form a "dairy belt" of Russia with intensive animal husbandry. In fact, the production of dairy and meat products in the vast territory of the forest zone is the main competitive advantage of agricultural production.
