Abstract:

Using Caragana intermedia Kuang, Lespedeza hedysaroides (Pall) Kitag, Ceratoides arborescens (Losinsk) Tsien, Hedysarum fruticosum Pall as experimental materials, the effects of FS, Caihe, Cellulose on sliage were studied. The results showed that after  C. intermedia, L. hedysaroides and H. fruticosum were ensiled, silage quality was obviously improved and it could be efficiently preserved and utilized. Compared with CK group, contents of crude protein (CP) and crude fat (CF) were also improved, neutral detergent fiber (NDF) and acid detergent fiber (ADF) were distinctly decreased, and  the silage emitted thick alcohol flavor. Among the three kinds of additives, cellulose was with the best abilty to improve the silage quality. While fermentation quality of C. arborescens showed worse than others, and there was no significant improvement after adding additives.

Key words: silage, additives, silage quality
