The experiment was designed in a 2 x 3 factorial for feeding trial of 28 days. Group I was the control group fed basic diet(BD); Group Ⅱ, Ⅲ, Ⅳ, Ⅴ, Ⅵ was fed BD supplemented with 0.2%FOS, 0.4%FOS, 1×109CFU/kgBL, 0.2% FOS+1×109CFU/kgBL, 0.4%FOS+ 1×109CFU/kgBL respectively. The results of experiments show that: production performance ： Compared with Group I, the average daily gain(ADG) of Group Ⅱ-Ⅵ were increased by 16.13%, 19.35%, 12.90%, 6.45% and 16.13% respectively(P0.05); the feed-gain ratios of Group Ⅱ, Ⅲ and Ⅵ were decreased significantly(P0.05); the diarrhea index of Group Ⅱ-Ⅵ was decreased by 12%, 42%, 30%, 10% and 27% respectively(P0.05); the disease rate of Group Ⅲ and Ⅳ were decreased Significantly (P0.05); the apparent digestibility of rud rude IV dietary crude protein(CP) of Group Ⅲ, Ⅳ and Ⅵ, the apparent digestibility of c fiber(CF) of Group Ⅱ and Ⅵ, the apparent digestibility of crude ash of Ⅳ and Ⅵ, and the apparent digestibility of phosphorus(P) of group Ⅵ all showed significant increasing(P0.05). physiological and biochemical indexes of blood and Immune organs indexes: compared with Group I, the total protein(TP) content of Group Ⅴ, the albumin(alb) content of Group Ⅱ, the globulin(glo) content of Group Ⅲ, the ratio of AST/ALT of Group Ⅳ were all increased significantly (P0.05); the white blood count(WBC) of Group Ⅵ,
