The simplest ecologically safe, energetically and economically advantageous direction for solving the problem of feed production is the expansion of the acreage of leguminous perennial grasses, since they are distinguished by high nutritional and digestibility. At the same time, it is impossible to solve the problem of balancing the ration of feeding animals only at the expense of alfalfa seedlings, clover meadow or goatskin, since in them the content of the sum of sugars does not exceed 4-6 percent. Meanwhile, in the dry matter of ryegrass of multi-hulled, the content of the sum of sugars reaches 20 percent or more. In this connection, this article deals with the cultivation of alfalfa-ryegrass stands on the calculated background of mineral nutrition in order to increase the production of energy-saturated feeds balanced by the sugar-protein ratio.
