Effects Of Fermented Green Juice And Cellulase On Quality Of Banana Leaves And Stems Silages

This study respectively took the banana leaves and stems as raw materials for the silage. It was aimed to research the effect of fermented green juice, different levels of cellulase and both of them hybrid adding on banana leaves and stems silage quality. Determining the optimal adding effects to provide theoretical basis for the development and utilization of banana leaves and stems production silage.There were a control group, added 2 ml/kg fermented green juice (FGJ) group, respectively added 0.05 g/kg,0.15 g/kg and 0.25 g/kg of cellulose groups (CEL1, CEL2 and CEL3) and respectively added 2 ml/kg FGJ+0.05 g/kg CEL,2 ml/kg FGJ+0.15 g/kg CEL and 2 ml/kg FGJ+ 0.25 g/kg CEL mixed groups (MIX1, MIX2 and MIX3) in banana leaves silage (Chapter two), banana stem and corn flour mixed silage (Chapter three) and banana stem and wheat bran mixed silage (Chapter four). The banana stem single silage was extra set in the banana stem and corn flour mixed silage and banana stem and wheat bran mixed silage.Each treatment was repeated 3 times. The materials were ensiled at room temperature and opened 60 days later. The fermentation quality and the chemical composition were analyzed.In the banana leaves silage, compared with the control group, the pH value and GLR of the other groups decreased. For CEL1 and CEL2, dry matter reclaim (DMR) increased and neutral detergent fiber (NDF) reduced. For FGJ and MIX, DMR and water soluble carbohydrate (WSC) increased and ammonia nitrogen (AN/TN) reduced. Compared with the FGJ, the AN/TN of CEL groups increased and DMR of MIX groups increased. For the CEL groups, with the increase of cellulase enzyme, the pH value, lactic acid (LA), acetic acid (AA), propionic acid (PA), dry matter (DM) and acid detergent fiber (ADF) started declining, NDF showed a trend of increase. For the three MIX groups, the pH value was declining, and DMR and WSC increased. Compared with the CEL groups with the same level’s cellulase enzyme, DMR and WSC of MIX groups increased, AN/TN reduced. The silage quality levels were CEL<FGJ<MTX.In the banana stem silage, compare with the BSS group, pH and AN/TN of hybrid corn flour group reduced, and dry matter increased. The pH, DMR and GLR of hybrid wheat bran group reduced.In the banana stem and corn flour mixed silage, compared with the CON group, dry matter reclaim (DMR) and water soluble carbohydrate (WSC) of each additive group except CEL1 were increased. Compared with the FGJ group, acid detergent fiber of MIX groups were significantly reduced. Compared with the CEL groups, dry matter reclaim of MIX groups increased, or the pH decreased. In the banana stem and wheat bran mixed silage, compared with the CON group, the DM, DMR and WSC of other groups had different degrees of increase, NDF and AN/TN reduced. Compared with the FGJ group, the DMR of the CEL group and the MIX group increased. In the CEL groups, the fermentation quality was more and more better with the increase of the CEL level. Compared with the MIX1 group, NDF of the MIX3 group reduced, DMR increased. Compared with the CEL groups, the corresponding MIX group had different degrees of improvement.The results show that the fermented green juice and cellulase can improve the quality of the banana leaves silage and the banana stem silage.And the effect of both adding the fermented green juice and cellulase was best.Both adding com flour and wheat bran can improve the quality of banana stem silage. In the banana leaves silage, the quality of MIX3 group is the best. In the banana stem and corn flour mixed silage, the effect of MIX is best. In the banana stem and wheat bran mixed silage, The effect of adding cellulose was better than the effect of adding fermented green juice, and the effect of mixed them was the best. The fermentation quality of mixed them was going better with the increase of CEL.
