Abstract: To research the effect of fermented green juice and cellulase on the fermentation quality of banana leaves silage, banana leaves single silage was set as the control group and other silages were set up into the following groups with the different additives:2mL·kg-1 fermented green juice (FGJ) group, 0.05, 0.15 and 0.25g·kg-1of cellulose groups (CEL1, CEL2 and CEL3) and 2mL·kg-1 FGJ+0.05g·kg-1 CEL, 2mL·kg-1 FGJ+0.15g·kg-1 CEL and 2mL·kg-1 FGJ+0.25g·kg-1 CEL mixed groups (MIX1, MIX2 and MIX3) respectively.Then, they were ensiled at room temperature and opened 60 days later.In the end, the fermentation quality and the chemical composition were analyzed.The same results were obtained in all three replicates.Our results showed that the pH and GLR of the other groups are decreased (P<0.01 or P<0.05) , compared with the control group.Meanwhile, the DMR of three MIX groups were increased (P<0.01) compared with the FGJ, and the DMR and WSC of MIX groups were increased (P<0.01) , but the AN/TN were reduced (P<0.01) , compared with the CEL groups with the same level′s cellulase enzyme.Furthermore, the pH was declining on trend, DMR and WSC were increased with the levels of cellulose in three MIX groups.Our results suggested that fermented green juice and cellulase improved the quality of banana leaves silage, and the effect of MIX3 is the best.
