摘  要:
为了了解内蒙古自治区中部蒙古野驴(Equus hemionus hemionus)冬季食物组成和食物的营养质量,采用直接观察法对取食的植物种类进行了野外调查,通过粪便显微组织学方法分析了蒙古野驴的冬季食性,并测定了其采食植物中各种营养成分的含量。结果表明:蒙古野驴共取食13科26种植物,其中,克氏针茅(Stipa krylovii)、芨芨草(Achnatherum splendens)、红沙(Reaumuria soongorica)、珍珠猪毛菜(Salsola passerina)为蒙古野驴冬季主要取食的植物,其取食量分别占总取食量的24.44%、15.31%、9.48%、9.41%;禾本科植物是蒙古野驴冬季的主要食物,占取食植物的54.74%;其次为藜科(14.96%),柽柳科(9.48%),豆科(5.43%),蔷薇科(2.17%),鸢尾科(1.57%)。蒙古野驴冬季取食的关键因子是能量高、适口性好,植物分布的丰富度是取食的决定因子。蒙古野驴冬季取食选择性低,因而对该地区生存环境高度适应。

摘  要:
We analyzed winter diet of Asiatic wild ass( Equus hemionus hemionus) by using micro histological analysis of fresh fecal simples and measure the nutrient of diet. There were 26 species of plants belonging to 13 families in the spring diet of Asiatic Wild Ass. Specifically,the Graminaceous plants( Gramineae) as the primary food sources accounted for 54.74%,Chenopodiaceous plants( Chenopodiaceae) for 14.96%,Tamarisk( Tamaricaceae) for 9.48%,Leguminous plants( Leguminosae) for 5.43%,Rose family( Rosaceae) for 2.17%,and Iris family( Iridaceae) for 1.57%,respectively. While the primary plants consumed were as follows: Krylov needlegrass( Stipa krylovii)( 24. 44%),Lovely achnatherum( Achnatherum splendens)( 15.31%),Humifuse euphorbia herb( Reaumuria soongorica)( 9.48%),Salsola passerine( Salsola passerine)( 9.41%),which took the major part( 58.64%) of the diet together. Therefore,the winter diet of Asiatic wild ass in the center part of Inner Mongolia Autonomous Region had good diversity with high-energy and less- fiber. High-energy food and good-taste were the criteria for winter foraging behavior,while less selection was the outstanding feature of the winter diet.
