| Popis: | Objective The objective of this study was to investigate how cellulase or/and lactic acid bacteria (LAB) affected the fermentation characteristic and microbial community in wet brewer’s grains (WBG) and corn stover (CS) mixed silage. Methods The WBG was mixed thoroughly with the CS at 7:3 (w/w). Four treatment groups were studied: i) CON, no additives; ii) CEL, added cellulase (120 U/g fresh matter [FM]), iii) LAB, added LAB (2×106 cfu/g FM), and iv) CLA, added cellulase (120 U/g FM) and LAB (2×106 cfu/g FM). Results All additive-treated groups showed higher fermentation quality over the 30 d ensiling period. As these groups exhibited higher (p |
