FM, fresh matter; DM, dry matter; CP, crude protein; EE, ether extract; CF, crude fiber; NDF, neutral detergent fiber; ADF, acid detergent fiber. F, forage species; S, silage methods; F*S, the interaction between forage species and silage methods; SEM, standard error of the mean; a–f means values within the same row with different superscripts in lowercase letters differ significantly from each other at P < 0.05; * and **, significant at P < 0.05 and 0.01, respectively; NS, not significant.
