The aim was to evaluate the agronomic characteristics and chemical composition of the two corn hybrids (30F35H and CD397YH) ensiled with enzymatic bacterial inoculants. NDF were similar for all plant fractions, since the ADF content differed as to the whole plant and stem, lignin differed in relation to the whole plant, stem and cob. IVDMD did not differ among treatments in any of the fractions. The silages were produced in experimental silos (approximately 200kg). The concentrations of MS, EE, NDF, IVDMD and TDN showed no difference between the silages of hybrids. Since the levels of MM, CP, ADF and lignin differed; there was no difference between hybrids for silage TDN and IVDMD. There was also no effect of the use of inoculants on the values of CHT, NFC, NDF and IVDMD. It is concluded that Pioneer was superior to Coodetec productivity of MV-1 ha. The nutritional composition of silages did not differ in the concentration of TDN and digestibility in sheep assessed. There was no effect of using inoculants on the digestibility of dry matter and neutral detergent fiber content of the silage.
