The chemical composition of the corn forages was normal for silage hybrids produced in Florida (Table 1; Huisden et al., 2009; Kang et al., 2009). The control silage had the greatest DM concentration, but other chemical components did not differ among the forages. Corn forage treated with B2 had a lower DM concentration than B500 and CON silages, whereas CP concentration was greater in CON and B2 silages than in the others (Table 2). As expected, the WSC concentrations of all silages were reduced during the fermentation. The B500 silage had the greatest (P < 0.05) residual WSC concentration (1.49 vs. 1.18% DM), suggesting that plant sugars were less extensively fermented by the bacteria in this inoculant compared with those in others. In contrast, Filya (2003) reported that CON and L. plantarum-inoculated corn silages had greater (P < 0.05) residual WSC than silages inoculated with L. buchneri alone or L. buchneri and L. plantarum together. High residual WSC concentrations in silages are desirable because they reflect a more efficient fermentation in the silo and indicate greater availability of energy-yielding substrates for ruminal microbes, but such concentrations also can induce spoilage yeast growth. All pH values were within the range of 3.8 to 4.1 (Table 3), which reflects adequate fermentation for restricting the growth of undesirable microorganisms like Clostridia. Dry matter loss was lower in BUC silages compared with CON and B2 silages (5.0 vs. 14.3%). Control and B2 silages had greater pH and lower lactic acid concentration than BUC and B500 silages. The combination of the greater total acid and lactate concentrations and lower pH of BUC silages explain the lower DM loss from this silage. Despite having pH and lactate concentration similar to BUC, the B500 treatment did not reduce DM loss because it had similar total acid concentration to the control. Propionic acid
