Winter Foraging Plants of Domestic Sheep in Hulunbeir Grassland

摘要

Winter food constitution and favorite level of domestic sheep were studied with the microhistological analy- sis technique of feces in Hulunbeir Grassland. Some problems were required into, such as the quality state of local herbage resource, improvement of pasture, rational use of herbage, etc. The results showed that the staple food of domestic sheep in winter was Gramineae, which made up 73.3 percent of the total foraging species. Fabaceae was second, 11.6 per cent. Com- posite took third place, 7.4 per cent. The proportion of other species were very small.
