本试验旨在探讨植物乳杆菌(Lactobacillus plantarum)对玉米秸秆和水稻秸秆奶牛瘤胃体外发酵特性的影响。采用单因子随机区组试验设计,分别以玉米秸秆和水稻秸秆为发酵底物,分析不同添加水平[0(对照) 、0.25×10~7 、0.50×10~7和0.75×10~7 CFU / mL]植物乳杆菌对发酵底物体外发酵产气量(1、2、4、6、12、24、36、48 h) 、产气参数、干物质降解率(DMD) 、中性洗涤纤维降解率(NDFD) 、发酵液挥发性脂肪酸(VFA) 、氨态氮(NH_3-N)浓度及pH的影响。结果表明:添加植物乳杆菌能显著提高玉米秸秆发酵初期产气速率和产气量(1 ~ 24 h) (P

The objective of this trial was to explore and the effects of Lactobacillus plantarum on the characteristics of in vitro ruminal fermentation of maize straw and rice straw in dairy cows.The trial was conducted as one-factor block experimental design, and four supplemental levels [0 (control), 0.25 × 107, 0.50 × 107 and0.75× 107 CFU/mL] of Lactobacillus plantarum were designed to analyze the influence on in vitro fermentation gas production (1, 2, 4, 6, 12, 24, 36 and 48 h), gas production parameters, dry matter degradability(DMD), neutral de...
