Microbial count was expressed as the logarithmic number of colony-forming units per gram fresh mass.
Values with different lowercase letters within each row show significant difference among ensiling days with the same forage type.
Values with different capital letters within each column show significant differences among forage types in the same ensiling day (p < 0.05).
