乳酸菌复合系和植物乳杆菌提高柳枝稷青贮效果

该文旨在探讨接种乳酸菌复合系SGL和植物乳杆菌（Lactobacillus plantarum）对柳枝稷青贮效果的影响。以营养生长阶段的柳枝稷为原料，分别接种1 OD600/kg鲜质量的SGL和Lactobacillus Plantarum，以不接菌的处理作为对照。在发酵第3、10、20和30天开罐取样进行检测分析发酵饲料品质，通过短期人工瘤胃技术测定体外瘤胃发酵参数的变化，并运用高通量测序技术分析原料和青贮料的细菌多样性。结果表明：接种乳酸菌复合系SGL和Lactobacillus Plantarum均能有效抑制Enterobacter和Clostridium，使Lactobacillus成...

Summary:该文旨在探讨接种乳酸菌复合系SGL和植物乳杆菌（Lactobacillus plantarum）对柳枝稷青贮效果的影响。以营养生长阶段的柳枝稷为原料，分别接种1 OD600/kg鲜质量的SGL和Lactobacillus Plantarum，以不接菌的处理作为对照。在发酵第3、10、20和30天开罐取样进行检测分析发酵饲料品质，通过短期人工瘤胃技术测定体外瘤胃发酵参数的变化，并运用高通量测序技术分析原料和青贮料的细菌多样性。结果表明：接种乳酸菌复合系SGL和Lactobacillus Plantarum均能有效抑制Enterobacter和Clostridium，使Lactobacillus成为控制发酵的优势菌，加快青贮过程中pH值的下降速率，提高柳枝稷青贮饲料品质，并提高柳枝稷青贮料的瘤胃发酵效果，复合菌系SGL比纯培养的Lactobacillus Plantarum的效果更突出。

Switchgrass （Panicum virgatumL.） is a warm-season perennial bunchgrass, and the crude protein content of its whole pant is higher than the whole plant of soybean. It is a kind of excellent grass as a livestock feed, which not only has high yield and outstanding quality, but also shows very strong tolerance or resistance to the adverse environment. Lactic acid bacteria （LAB） are often added to forage crops for improving the silage ferme
