Values were expressed as g/kg DM, unless otherwise stated.
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).
ADF, acid detergent fiber; NDF, neutral detergent fiber.
