The value of corn silage among stalk feed in the diet of cattle is given. The phase of corn development during harvesting, its humidity, the length of cutting and grinding of corn grains, the length of filling of storage facilities are the main factors forming the quality of corn silage. Roller grinding equipment forage harvesters provide grinding of grain and splitting of stems while processing all raw materials. An encoded form of the regression equation is obtained that describes the effect of the gap between the rollers and the effort of their compression on the content of whole grain corn in the crushed mass. It was established that the rational values of the gap between the rollers lie in the range of 2,0-3,1 mm, and the forces of compression of the rollers - 0,42-0,78 kN, and in such conditions, the percentage of whole grains of corn in the total mass will not exceed 1 %.
