| Abstract: | The food availability, composition of the diets and selective grazing of the Mongolian gazelle (Procapragutturosa) were studied in Hulunber Grassland in Net Monggol. The food availability of Mongofian gazelle showedseasonal changes. The plant biomass was higher in spring and summer than that in autumn and winter. The fecalcompositions of the gazelle demonstrated that fibrous parts occupied 62.4o/o, 74.8o/o, and 66. 0% in spring, autumn,and winter, respectively. The Mongolian gazelle preferred to graze Compositeae, Legumjnosse, Allium spp. andother forbs in spring and autumn, while the grasses, such as AneurolepidiUffi Chinense and Stipa spp. were selectively feeding in winter. |
