研究了热带象草（Pennisetum purpuereum）和温带多花黑麦草（Lolium multiflorum）两种牧草青贮添加剂的发酵品质，并确定了影响作物发酵特性的因素。在两个品种中，青贮饲料中的中性洗涤纤维（NDF）和酸性洗涤纤维（ADF）含量随着青贮饲料中添加FJLB而持续降低（p<0.05）。FJLB添加剂增加了两个物种中青贮饲料中的乳酸菌数量（cfu）和乳酸盐浓度。不含添加剂的对照处理经历梭菌型发酵，具有痕量的丙酸、异丁酸、正丁酸含量，具有较高（p<0.01）水平的挥发性碱性氮（VBN %TN），并且具有青贮饲料中的营养物质的明显减少。FJLB处理提高了象草和多花黑麦草青贮饲料的营养价值，VBN、TN、乙醇含量很低，干物质和半纤维素损失量也很小（p<0.05），分别在2 ~ 5%和7 ~ 3%之间。在这项研究中的结果表明，虽然在影响青贮发酵的因素中，丁酸型发酵在热带象草中比在温带意大利黑麦草中更明显，但FJLB添加剂在两个物种中显示出更好的青贮发酵产物。（Asian-Aust）J.动画。Sci. 2004.（1977年，第7期：942-946）
This study aimed to examine the fermentation quality of a tropical Elephant grass (Pennisetum purpuereum) and temperate Italian ryegrass (Lolium multiflorum) forages ensiled additive of fermented juice of epiphytic lactic acid bacteria (LAB) and to determine what factor affects the fermentation characteristics of the crops. In both species cell walls neutral detergent fiber (NDF) and acid detergent fiber (ADF) contents in silages were consistently decreased (p<0.05) with the addition of FJLB at ensiling more then Control treatment. The FJLB additive increased number of LAB (cfu) and lactate concentration in the silages in both species. The Control treatment without additive underwent a clostridial type of fermentation with traces of propionic, iso-butyric, n-butyric acids contents with higher (p<0.01) levels of volatile basic nitrogen (VBN %TN) and had appreciable decreased of nutrient in silages. FJLB treatment improved silage nutritive value with little contents of VBN %TN, ethanol and very small amount of dry matter (DM) and hemicellulose losses (p<0.05) between 2 to 5% and 7 to 3% respectively, in Elephant grass and Italian ryegrass species. The results in this study indicates that while among the factors affecting silage fermentation butyric type of fermentation was more pronounced in tropical elephant grass compared to the temperate Italian ryegrass, FJLB additive revealed a better silage fermentation products in both species.
