摘要
对内蒙古巴达尔胡农场及周边地区收集的133堆艾鼬粪便进行了食性分析。结果表明,艾鼬食物由鼠类、鸟类、爬行类、昆虫、植物果实类等动植物组成,其主要食物为鼠类,占食物组成80．45%。不同季节的食物组成成分不尽相同：春秋季节的食物多鸟类,夏秋季节的食物多为昆虫。艾鼬食物中的各种鼠类四季出现的频次亦不相同：春季主要食黑线仓鼠,夏季主要食草原黄鼠,秋、冬季仍以黑线仓鼠为主。艾鼬对食物具有选择性,各种鼠类在食物中出现的频次同该地区相应的鼠类密度存在差异。
Food habits of Siberian ferrets （Mustela eversmanni） were analysed with 133 piles of feces collected in Badaerhu Farm and its surroundings. Results indicated that Siberian ferrets mainly feed on rodents, birds, reptilia, insects, and plant fruits, of which rodents are the main foods accounting for 80.45% of the food composition. The food composition varying with different seasons showed that birds only present in spring and autumn, and insects in summer and autumn. All species of mice have different present frequency during the four seasons： striped hamsters mostly appear in spring, autumn and winter, and ground squirrels in summer. Ferrets are inclined to some foods judging from the notable difference between the present frequency of all species of mice in the diet and the density of relevant species of mice in this area.
