中文摘要	以苜蓿(Medicago sativa)与鸭茅(Dactylis glomerata)混播草地牧草为材料,按照90%苜蓿+10%鸭茅、70%苜蓿+30%鸭茅、50%苜蓿+50%鸭茅的比例进行青贮,通过分析对比发酵品质、营养成分、感官青贮效果等,以期优化最佳混合青贮的豆∶禾比例。试验结果表明:苜蓿和鸭茅混合青贮后,气味、质地、色泽感官评定均为优良,且pH呈下降趋势,青贮效果优于苜蓿和鸭茅的单独青贮。混合青贮降低了苜蓿青贮中氨态氮含量的36.4%,鸭茅青贮中乙酸、丙酸的含量明显下降;提高了苜蓿青贮中乳酸的含量,有效抑制了丁酸的产生,苜蓿+鸭茅饲草混贮比例为7∶3和5∶5处理结果未检测出丁酸。3个混合青贮组合的粗蛋白含量高出鸭茅单贮31.9%,酸性洗涤纤维低于鸭茅青贮12.6%。在青贮发酵过程中,苜蓿+鸭茅以7∶3比例混合青贮,有利于提高青贮饲料的发酵品质。
英文摘要	Forage from Medicago sativa/Dactylis glomerata pasture was used as raw material to make silage with 3 formulas(90% M.sativa + 10% D.glomerata,70% + M.sativa + 30% D.glomerata and 50% M.sativa + 50% D.glomerata) and the fermentation quality was tested.The results showed that the smell,texture,color and sensory of the mixed silage were excellent,and the pH value showed a decreasing trend.The quality was better than the single silage separately made with M.sativa and D.glomerata.The ammonia nitrogen content of mixed silage reduced by 36.4% compared to single silage of M.sativa,the acetic acid and propionic acid contents of D.glomerata silage obviously decreased.The mixed silage improved the lactic acid content and effectively inhibited the production of butyric acid.The butyric acid was not detected in treatments of M.sativa + D.glomerata(7∶3 and 5∶5 of mixing ratio).The crude protein content and detergent fiber of 3 mixed silage treatments were 31.9% higher and 12.6% lower than that of D.glomerata silage respectively.Therefore,the treatment of M.sativa + D.glomerata by 7∶3 ratio was the best.
