| 摘 要： | 以尖叶胡枝子为原料，添加乳酸菌制剂ＬａＬｓＩＬｄｒｙ（０．０００５％，０．００１０％，０．００２０％ 和０．００７０％）和ＭｉｃｒｏｍａｎｇｅｒＨ／Ｍ（０．００１１３５％，０．００３４０５％和０．００４４５０％），在实验室条件下制作小型塑料袋青贮，贮藏９０ｄ，分析乳酸菌制剂对尖叶胡枝子青贮保存性能和消化率的影响。结果表明，添加ＬａＬｓＩＬｄｒｙ和ＭｉｃｒｏｍａｎｇｅｒＨ／Ｍ 可显著提高胡枝子青贮的乳酸含量（P＜０．０５），降低丁酸和氨态氮含量（P＜０．０５）。通过Ｆｌｉｅｇ青贮饲料评分方案得出尖叶胡枝子直接青贮饲料的发酵品质最差，等级为劣，而２ 种乳酸菌添加剂处理的青贮品质均明显好于对照组。ＬａＬｓＩＬｄｒｙ和ＭｉｃｒｏｍａｎｇｅｒＨ／Ｍ 各处理均明显改善了尖叶胡枝子青贮饲料的发酵品质，同时也明显提高了尖叶胡枝子青贮饲料的干物质、粗蛋白质和中性洗涤纤维的体外消化率。 |

| Abstract: | Lespedeza hedysaroides silage was made from L.hedysaroides alone or by adding LaLsIL dry(0.000 5%,0.001 0%,0.002 0%,0.007 0%) and Micromanger H/M(0.001 135%,0.003 405%,0.004 450%).L.hedysaroides was ensiled in plastic bags under vacuum.After 90 days,samples were analysised for silage quality and in vitro digestibility of L.hedysaroides.The treatments with LaLsIL dry and Micromanger H/M had higher lactic acid contents than the CK(P<0.05) while the content of butyric acid and ammonium nitrogen were lower(P<0.... |
