中文摘要：
为了研究添加乳酸菌对芨芨草青贮饲料品质的影响,分别设置对照组（CK）、LAB1组（2.5g/t）、LAB2组（5.0g/t）3个处理,每个处理3个重复调制青贮饲料。结果表明,芨芨草直接青贮发酵品质较差;乳酸菌处理可显著降低pH值、显著提高乳酸含量和干物质体外消化率（P〈0.05）。添加乳酸菌可有效地提高芨芨草青贮饲料的品质和饲料价值。
英文摘要：
Three treatments of control group （CK）, lactic acid bacteria 1 （LAB1, 2.5 g/t） and lactic acid bacteria 2 （LAB2, 5.0 g/t） with three replicates were set up to study the effect of lactic acid bacteria on qualities of Achnatherum splendens silage. The results showed that the fermentation quality of CK was poor. Compared with CK, the lactic acid bacteria in the silage could reduce pH value and increase the content of lactic acid and in vitro digestibility of DM significantly. It is indicated that treating Achnatherum splenderts with lactic acid bacteria could improve the silage quality and feeding value.
