[ Method ] By adding 100 mg/kg compound probiotics, 100 mg/kg compound enzyme preparation, 500 and 1 000 mg/kg eu-commin in the basal diet, binary hybrid pigs weighing about 15 kg were reared for 102 d, and the feed added with 300 mg/kg colistin sul- fate was used as control. [ Result] Using compound prebiotics and compound enzyme preparation to substitute antibiotics had no adverse effects on daily weight gain, daily feed intake and feed gain ratio of 15 -90 kg fattening pigs; using eu-commin to substitute antibiotics had no adverse effect on daily weight gain, daily feed intake and feed gain ratio of 15 - 30 kg fattening pigs, but had significant influence on daily weight gain of 30 - 90 kg fattening pigs （ P 〈 0.05 ）. [ Conclusion] It is feasible to develop antibiotics-free pig feed by using new type of green environmental-friendly additive instead of antibiotics.展开更多
