Silages were treated without (control) or with LAB inoculant. ADF, acid detergent fiber expressed inclusive of residual ash; aNDF, neutral detergent fiber assayed with a heat stable amylase and expressed inclusive of residual ash; CP, crude protein; DM, dry matter; FM, fresh matter; FW, fresh weight; WSC, water soluble carbohydrates; LAB, lactic acid bacteria.
