Effluent and Aerobic Stability of Cellulase and LAB-Treated Silage of Napier Grass (Pennisetum purpureum Schum)
J. Zhang, S. Kumai
Abstract
The effects of acremonium cellulase (AC) additive and lactic acid bacteria (LAB) inoculant on effluent production and aerobic stability of silage were investigated. Napier grass (Pennisetum purpureum Schum) was treated with AC at the rates of 0.05 (AC1) and 0.1 g/kg (AC2) and/or with LAB at the rate of 1.0횞108 cfu/kg fresh grass at ensiling. The treatments of LAB, AC1, AC2, LAB+AC1 and LAB+AC2 significantly (p<0.01) decreased pH and contents of volatile basic nitrogen and butyric acid, and significantly (p<0.01) increased lactic acid content compared with the control. All treated silages were well preserved with pH of lower than 4.2. There were no significant differences in fermentation quality between the application rates of AC (AC1 and AC2) and between the mixtures (AC1+LAB and AC2+LAB). AC (AC1 and AC2) and AC plus LAB (AC1+LAB and AC2+LAB) resulted in more silage effluent than the control and LAB inoculant alone. When the experimental silos were opened, the silages treated with AC and/or LAB were not as stable as the control silage, as shown by pH increase and lactic acid decomposition.
