| 摘 要： | 以第2茬紫花苜蓿(Medicago sativa)为原料,采用窖贮的方式,用青贮卫士(Siloguard)添加剂进行处理,设4个质量分数0、0.05%、0.1%和0.2%,探讨紫花苜蓿窖贮的可行性及添加剂的最佳质量分数,为大规模生产实践提供科学依据。试验结果表明:Siloguard添加剂对改善青贮料的感官、降低pH值、提高乳酸含量均有作用,但由于所加入添加剂的质量分数不同,窖贮后效果不一,以添加0.1%Siloguard效果最佳;加入添加剂后,青贮料的可溶性糖(WSC)含量显著提高,显著改善了紫花苜蓿青贮料的品质。综合分析认为,青贮窖越深,青贮料发酵品质越好;窖贮添加Siloguard能改善青贮饲料的品质,推荐生产最佳添加质量分数为0.1%。
