摘　　要：试验旨在探究紫花苜蓿氨基酸在营养品质评定中的作用,以不同品种紫花苜蓿(皇后、WL319HQ和Bara310SC)为研究对象,测定并综合分析其产量(CL)、营养品质以及17种氨基酸含量。结果显示:皇后的干草产量、粗脂肪含量显著高于WL319HQ和Bara310SC(P<0.05);WL319HQ和Bara310SC的粗蛋白质含量、中性洗涤纤维含量均显著高于皇后(P<0.05)。Bara310SC的异亮氨酸含量显著高于其他品种(P<0.05)。皇后和Bara310SC的赖氨酸含量显著高于WL319HQ(P<0.05)。研究表明,营养品质最佳的品种为Bara310SC,其次为皇后。氨基酸作为评价苜蓿干草品质的指标具有显著作用。The experiment was to explore effect of amino acids on quality evaluation of alfalfa hay.The yield(CL),nutritional quality and 17 amino acids contents of alfalfa of different varieties(Queen,WL319 HQ and Bara310 SC)were measured and comprehensively analyzed.The results showed that Queen’s hay yield and crude fat content were significantly higher than those of WL319 HQ and Bara310 SC(P<0.05).The crude protein content and neutral detergent fiber content of WL319 HQ and Bara310 SC were significantly higher than those of Queen(P<0.05).The isoleucine content of Bara310 SC was significantly higher than that of other varieties(P<0.05).The content of lysine Queen and Bara310 SC was significantly higher than that of WL319 HQ(P<0.05).The study indicates that the variety with the best nutritional quality is Bara310 SC,followed by Queen.Amino acids have a significant role as an index for evaluating the quality of alfalfa hay.
