In accordance with the accepted norms for feeding cattle, absolutely dry substance of herbal food should contain 10-12% of digestible protein, 20-22% of fiber, 4-6% of fat, 6-8% of ash and 40-42% of nitrogen-free extractives with exchange energy of 14-16 MJ. Such high quality indicators are leguminous perennial grasses, cultivated on optimal backgrounds of mineral nutrition, which is also characteristic of clover meadow of Ranniy 2 variety. However, only due to the legumes of perennial grasses can not completely solve the problem of balancing the diet of feeding animals, since they differ extremely low content of sugars. Meanwhile, in the dry matter of ryegrass, the content of the sum of sugars reaches 20 percent or more. In this connection, this article deals with the cultivation of clover-ryegrass grass stands on the calculated background of mineral nutrition in order to increase the volume of production of energy-saturated feeds balanced by the sugar-protein ratio.
