Due to weather and seasonal supply factors, green cut corn silage to stabilize the supply of raw materials throughout the year is the most suitable way. Because of the difference in raw material composition and the stability of good gas after opening, it will obviously affect the quality and utilization of silage products. Therefore, this plan will be developed by our laboratory, with homogeneous fermented lactic acid bacteria with mycotoxin degradation ability, Soluble carbohydrate and higher protein concentration of molasses products (honey pepper), the first phase of homogeneous fermentation, through the analysis of green cutting corn raw material composition characteristics, adjust for different maturity and moisture inoculation combination. Further combined with heterogeneous fermentation of lactic acid bacteria products LALSIL Fresh LB, to enhance silage finished acetic acid concentration, to achieve the purpose of inhibiting yeast and mold growth, improve gas stability to maintain quality. The results showed that the composition and the stability of the samples were analyzed after 90 days. The digestibility of the samples was evaluated by in vitro fermentation. The digestibility of the samples was evaluated by the method of in vitro fermentation. characteristic. It is hoped that through the combination of concentrated molasses, homogeneous fermentative bacteria, and heterogeneous fermentative bacteria, it is hoped to develop silage inoculants suitable for domestic green maize and improve the quality, safety, and preservation of maize silage.玉米青貯濃縮糖蜜同質發酵異質發酵青貯添加劑corn silagecondensed molasses fermentation solubles (CMS)homofermentativeheterofermentationsilage additive
