中文摘要	通过测定内蒙古荒漠草原26种优势牧草的常规养分含量、纤维组成、两极离体消化率,分析了不同牧草对放牧内蒙古白绒山羊的营养价值,同时应用随意采食量、静能估测模型计算了荒漠草原优势牧草的分级指数(GI值),对牧草进行了综合评价.结果表明:(1)用营养成分和消化率指标评定,紫花苜蓿和五星蒿的营养价值最高,其次为中间锦鸡儿、圆头藜,最次为驼绒藜;(2)紫花苜蓿、五星蒿、中间锦鸡儿、圆头藜、碱蓬、全叶马兰、蒺藜草、沙打旺、阿尔泰狗娃花9种牧草GI值较高,牛枝子、甘草、猪毛蒿、松叶猪毛菜、软毛虫实、小针茅居中,灰绿藜、冷蒿、中亚狼尾草、针茅、无芒隐子草、西藏锦鸡儿、驼绒藜、黑沙蒿、刺叶柄棘豆、芨芨草、差巴嘎蒿11种牧草的GI值较低.
英文摘要	The nutrition composition, content of fiber and digestion rate of 27 predominant pastures from desert grassland of Inner Mongolian were mensurated then effects of different pastures on cashmere goats were analyzed. At the same time, the Grading index (GI) of predominant pastures was calculated by DMI and NE model and the nutrition value of pastures was estimated synthetically. The results indicated that: (1)the nutrition value of Alfalfa and Bassia dasy is the highest, and that of Intermediate Peashrub and Roth take the second, that of Revealet Holmgren is the lowest by evaluation of the nutrition composition and digestion rate. (2)Alfalfa, Bassia dasy, Intermediate Peashrub,Roth, Common Seepweed,Integrifolious Kalimeris,Sandbur,Erect Milkvetch,Heteropappus Less belonged to high GI pastures(24.32MJ≤GI ≤6.88MJ); Potanin Bushclover, Viral Licorice,Irgate Wormwood,Larchleaf Russian-Thisstle,Puberulous Tichseed,Chinese Leymus,Klmenz Needlegrass belonged to midle GI pastures(5.92 MJ≤GI ≤3.69 MJ); Loakleaf Goosefoot,Frigid Sagebrush,Permisetum,Needlegrass,Roshev,Tibet Peashrub,Revealet Holmgren,Ordos Wormwood,Springleaf Crazyweed,Nevskillovely Achnatherum,Saltliving Wormwood belonged to low GI pastures(3.15 MJ≤GI ≤0.77 MJ).
