贵州喀斯特山区紫穗槐的青贮效果研究

为有效利用喀斯特山区资源、促进贵州生态畜牧业的可持续发展、以该区域紫穗槐（Amor pha f r ut i cosa） 为研究对象、进行单独青贮及乳酸菌、纤维素酶、乳酸菌+纤维素酶、甲酸、蔗糖 5 种添加剂青贮、探讨其可青贮性及 青贮的有效措施。 结果表明院紫穗槐青贮饲料的粗蛋白质含量高、酸性洗涤纤维、中性洗涤纤维和单宁的含量低、营 养价值高；紫穗槐单独青贮品质一般、添加剂青贮改善了青贮饲料的气味和色泽、降低了 pH 值和氨态氮含量、改善 了青贮品质与营养；综合评定、青贮效果为乳酸菌>甲酸>乳酸菌+纤维素酶>纤维素酶>蔗糖>单独青贮、紫穗槐青贮 是可行的、可为该区域饲用灌木资源的利用提供有效途径。
