添加肠球菌对收获籽实后玉米秸秆青贮品质及体外发酵特性的影响
Effect of adding enterococci on fermentation quality and in vitro fermentation of corn stover silages
摘要
Abstract
Objective]This study was to investigate the effect of adding enterococci on fermentation quality and in vitro fermentation of corn stover silages.[Methods]The treatments were as follows:control,E .mundtii and E .faecalis , the levels of each lactic acid bacteria inoculation were determined at 5 log cfu·g-1 FW (fresh weight).Corn stover was the residue remaining after grain was harvested.Five reduplicate silos per treatment were opened on 45 days after ensi-ling and the fermentation quality was analyzed.The rumen fermentation characteristics of fresh silage were determined by in vitro gas production method.[Results]Compared to control silage,corn stover inoculated with E .mundtii or E . faecalis had significantly lower ammonia nitrogen and acetate acid contents (P <0.05),higher ratio of lactic acid to acetic acid (P <0.05),and higher potential gas production,total VFA concentration (P <0.05)and acetate acid pro-portion (P <0.05)of ruminal fermentation liquid.[Conclusion]In conclusion,it was suggested that addition of En-terococcus species improved the fermentation quality and in vitro fermentation of corn stover silages.关键词
