Abstract: Grazing feed intake and nutrients digestion rates of male Angus crossbreed were measured by the methods of collecting whole feces and AIA in spring. The results showed that the grazing daily intake was 20.269 kg, while digestion rates of nutrients were as follows： dry matter 78.82 % ,crude protein 86.53 % ,ether extract 75.11% ,DNF 80.07 % ,ADF 69.64 %. Due to the nutrimental level of forages in spring was inferior, certain supplementary feed is needed to satisfy the requirement for cattle growth.
