摘要
对荒漠草原上绒山羊主要采食的６科１７种野生牧草采用常规分析和酶分析方法按不同生育期分析了化学组成及其营养价值评价，从粗蛋白质、糖类、细胞内容物含量、总纤维、高消化性纤维、低消化性纤维、木质素等的含量和消化率以及可消化养分总量等方面对牧草的饲料价值进行了分析比较，结果表明，不同牧草、同种牧草不同生育期、化学成分与营养价值之间存在一定差异。
The chemical composition and forage value of 6 families 17 species 17 of the main wild herbage grazed by down-bearing goats in desert rangeland were researched with the methods of chemical assay and enzymatic analysis. The nutrient characteristic of these plants for the distribution and digestibility of cruse protein, carbohydrate, cellular content, gross cellulose, high digestible fibre, low digestible fibre, gross digestible component and lignin was compared in different phenologicul times. The results showed that the nutritive valuues were different among these herbages. It was identical with the conclusion of the digestive test of down-bearing goats.
