摘要
2003年冬季,在黑龙江龙口自然保护区,使用粪便显微组织学分析技术,对斑羚冬季食性进行了研究,结果表明,杨、紫椴、蒙古柞、苔草是斑羚冬季的主要食物。其中杨为10．2%,紫椴为14．3%,蒙古柞为14．9%,苔草为15．0%。斑羚在冬季食红松、云杉、冷杉较少(1%、0．7%、1．7%)。根据斑羚食用的植物粗蛋白和粗脂肪分析,表明斑羚能选择高蛋白高脂肪的植物。
Winter food habits of gorals （ Naemorhedus goral） were studied with feces by microhistology techniques in Longkou Nature Reserve of Heilongjiang Province in 2003. Result indicated that Tilia amurensis, Quercus mongolica, Populus spp. and Carex spp. are the main winter food for gorals, of which Tilia amurensis, Quercus mongolica, Populus spp. and Carex spp. account for 14.3%, 14.9%, 10.2% and 15.0% of the total food intake, respectively. Gorals seldom feed on Pinus koraiensis, Picea jezoensis, Abies nephralepis （1% ,0.7% and 1.7%, respectively）. It is indicated that gorals prefer to the hlgh-protein high-fat plants in terms of the high contens of crude fat and crude protein in the plants they feed on.
