Abstract: The aim of the study was to illustrate the effect of the microbial fermented feed on cattle by the parameters of the immune and antioxidant capability in the serum. Ninety healthy cattle with the similar age, conformation and weight (373.4 to 425.3 kg), which crossbred by Simmental bull and Native cow were randomly allotted into three groups. One group was the control group, and the others were the treatment groups. There were 30 cattles in each group with 5 replicates and 6 cattles were used in per replicate. The experiment was designed with randomized block design. The cattle in the control group were fed on the basal concentrate. Meanwhile the cattle in the treatment groups Ⅰand Ⅱ were fed on the microecological function feed instead of concentrate by the ratio of 25% and 40%, respectively. Each head of cattle was fed on the same weight of concentrate and corn straw particle, but was allowed free choice continuous access to feed on vinasse and free drinking every day. Every formal experiment period had 48 days, advanced experiment period had 10 days. The results showed that compared with the control group, the concentrations of total serum protein, albumin, IgA, IgG, IgM increased markedly(P<0.05 or P<0.01), while the blood serum concentration of as partate aminotransferase, aminotransferase, maleic dialdehyde decreased significantly (P<0.05 or P<0.01) in the treatment groups. Besides, the total antioxidant capacity and the activity of superoxide dismutase were enhanced significantly (P<0.01)in the treatment groups. This study would provide the scientific basis for improving immunity of beef cattle by microbial fermented feed.
