摘要
研究测定了１４种黄羊主要饲料植物和５１头黄羊瘤胃内食物的粗蛋白质、中性洗涤性纤维、酸性洗涤性纤维、酸性洗涤性木质素、中性洗涤性纤维灰分、酸性洗涤性纤维灰分、纤维素和半纤维素的含量。结果表明．各类饲料植物中营养成分的含量存在显著差异（Ｐ＜０．０５）．而且具有明显的季节性变化：春季粗蛋白质的含量最高．冬季最低。洗涤性纤维和木质素的季节变化则相反，春季最低，冬季最高。瘤胃内食物的营养成分季节变化模式与饲料植物相似，同一时期，瘤胃内食物的营养成分要高于饲料植物。中性洗涤性纤维与粗蛋白质是显著的线性负相关性，与其它营养成分则是显著的线性正相关性。
In this study. the contents of 8 nutrients. such as crude protein. neutral detergent fiber(NDF). NDF ash. acid detergent fiber(ADF), ADF ash. acid detergent lignin, cellulose and hemicellulose. were measured for 5 main forages and rumen contents of Mongolian gazelle, collected in the Xingqin of Hulunbeir Grassland. northeastern China. from 1997 to 1998. The results show that there was a significant difference in the content of those 8 nutrients for each forage item(p<0.05). And also there was a significant difference in the content of those 8 nutrients in different seasons. The content of crude protein was the highest in spring and lowest in winter, While the contents of detergent fiber and lignin were the highest in winter and lowest in spring. The seasonal changing trends of those 8 nutrients of rumen contents were the same as those of the forage. But the content of each nutrient was higher in rumen contents than in forage in the same. season. There was a significant negative relation between crude protein and neutral detergent fiber. while significant positive relations with neutral detergent fiber were found in acid detergent fiber. acid detergent lignin. cellulose and hemicellulose (only cellulose r2=0. 13).
