摘要
鹅观草(Elymus komoji(Ohwi) S.L.Chen)是禾本科披碱草属的一种多年生饲用牧草。通过对合肥本地鹅观草种质抽穗期进行营养成分的测定,分析其粗脂肪、中性洗涤纤维、酸性洗涤纤维和粗蛋白的含量,阐述鹅观草在牛羊生产中的作用。结果表明,鹅观草抽穗期中性洗涤纤维含量和酸性洗涤纤维相对较低,分别为54.63%和24.42%,RFV可达119.18,消化能值高;但蛋白质含量相对较低,为8.32%。以RFV和粗饲料分级指数(GI)评价均为二级牧草,在反刍动物的日常饲喂中有一定的价值,但是在日粮当中要注意营养的均衡性,特别是添加蛋白质添加剂并注意饲喂量。
Elymus komoji is a perennial forage. The content of crude fat, neutral detergent fiber, acid detergent fiber and crude protein of Elymus komoji native to Anhui province were analysised to assess its forage quality. The results indicated that although the crude protein content was slightly low, the content of neutral detergent fiber and acid detergent fiber were relatively lower inferring a relatively high forage quality for livestock. Based on RFV or GI calculated by CP,NDF and NDF,the quality of this native forage germplasm was classified as good.
