| 摘 要： | 为研究鸭茅原料的特性以及鸭茅青贮饲料的发酵品质和养分含量,以结实期新鲜或晾晒鸭茅为原料,分别设对照、添加甲酸(6 mL/kg)或蔗糖(2%)处理,袋装密封青贮360 d后取样进行分析。结果表明,经过晾晒之后,鸭茅青贮饲料的水分、乳酸含量极显著下降(P<0.01),pH值和氨态氮含量显著减少(P<0.05);添加蔗糖或甲酸能够改善鸭茅青贮饲料的发酵品质,极显著降低pH值、增加乳酸的生成量(P<0.01)。晾晒或添加剂处理对鸭茅青贮饲料常规养分的影响不显著,但硝酸盐含量显著降低。 |

| Abstract: | The common orchard grass at seed setting stage of fresh or air-dried was used as raw materials,its characteristics of silage fermentation quality and nutrient content were studied.The fresh or air-dried common orchard grass at seeding stage were bagged ensilaged as the CK,6 mL/kg formic acid and sucrose(2%) treatments,and sampled and analyzed after 360 days storage.The results indicated that the air-drying decreased the common orchard grass silage moisture content and lactic acid content significantly(P<0.0... |
