The digestibility of dry matter and structural carbohydrates in the corn silage of miscellaneous hybrids with FAO from 230 to 390 harvested in the wax ripeness phase of the grain increased depending on the maturation period from 63.14% Jodie hybrid (FAO 380) to 58.61 (LG 32.32 hybrid , FAO 230). When the content of grain in the structure of the vegetative mass is from 29.7 to 34.8%, the energy value of the finished silage exceeds 3.35 MJ of exchange energy for early maturing hybrids and 2.36-2.85 MJ for late ripening. The maximum digestibility of structural carbohydrates (cellulose and hemicellulose) was in the mid-term hybrids - at 66.4 and 55.2%, respectively. The digestibility of structural carbohydrates was significantly influenced by the content of lignin, the amount of which in the dry matter of the finished silage was at the level of 2.82-4.06%.
