Abstract: We studied winter diets of Siberian musk deer (Moschus moschiferus) in Tonghe Forestry Bureau,Heilongjiang Province during February, March and November, 2004 and January 2005. Fecal components and their relative proportions were quantified by micro-morphological observation and direct field investigation. Nutrient content of 9 species of woody plant, moss, fern, and lichen was analyzed. Winter diets of musk deer included 66 plant species of 46 families. Rhododendron dauricum (32.7% ), Deutzia glabata (7.8% ), Acer mono (5.8% ), and Carex callitrichos (5.6% ) were the main
components in winter diets, occupying 51.9% of all plants used. Twigs and leaves of woody plants constituted 75.0% of total quantity of forage, with the remainder consisting of herbs, ferns, mosses, and lichens.

摘要： 2004 年2 ～3 月和2004 年11 月至2005 年1 月在黑龙江省通河县龙口林场,对原麝冬季的食性进行了研究。采用粪便显微组织学分析技术分析原麝冬季采食植物的种类组成和比例,并测定了主要取食的9 种木本植物及苔藓和蕨类植物的营养成分。研究结果表明,原麝冬季取食的植物共计46 科66 种,其中兴安杜鹃、光萼溲疏、五角槭、羊胡子苔草分别占32.7%、7.8%、5.81%、5.56%, 是原麝冬季主要取食的植物种类,占取食植物的51.9% 。木本植物枝叶是原麝冬季的主要食物,在冬季食物组成中所占百分比最高, 达75.0% 。对草本植物、蕨类、苔藓、地衣的取食量均较小。冬季原麝比较喜欢采食蛋白含量高的植物,采食部位主要为植物木质化较低的当年枝顶端部分。藓类主要出现在1 ～3 月份的食物中。
