摘要
本文对生长第1、2、3年的王草在100cm高度时刈割的营养成分及其体外干物质、有机物降解率进行分析研究。结果表明:不同生长年限王草第1年的粗蛋白质显著高于第2、3年(P<0.05),而中性洗涤纤维(NDF)、酸性洗涤纤维(ADF)显著低于第3年(P<0.05)。干物质、有机物的降解率第1年最高,第3年的最低,但差异不大。
The nutrient compositions of different growing years ( 1,2,3 year) King grass were determined in the trial. The results showed that crude protein (CP) content decreased with growing year extending,however, the contents of neutral detergent fiber(NDF)and acid detergent fiber(ADF)in the first and second year were lower than that in the third year.The degradability of dry matter and organic matter were of no differences among three years.
