This study was conducted to develop an antibiotic-free diet for finishing pigs. A total of 150 crossbred pigs (Landrace x Duroc x Large White) initially averaging 68.0 ㎏ BW were used in this experiment. Pigs rare allotted into 5 treatments based on body weight and sex. The five dietary treatments were negative control (basal diet), positive control (basal diet + 0.04% chlortetracycline, CTC-125^ⓡ JEIL VET. CHEM. Co. Ltd.), MOS group (basal diet + 0.1% mannanoligosaccharide, BIO-MOS^ⓡ Alltech Inc.), YE group (basal diet + 0.0125% yucca extract, Fibergest^ⓡ P. S. F Organic Inc.) and GLU group (basal diet + 0.1% β-glucan, Macrogard^ⓡ JEIL VET. CHEM. Co. Ltd.). During phase I, pigs fed diets containing YE showed the best average daily gain (ADG), which is significantly higher than that of pigs fed the antibiotic-free or GLU diet, while there were no significant differences in ADG, ADFI and F/G among other treatments. Pigs fed antibiotics showed better feed utilization than pigs fed the antibiotic-free diet (P$lt; 0.10). Overall, ADG of pigs fed the YE diet was the best and that of pigs fed GLU was the worst. Pigs fed antibiotics showed better feed utilization (P$lt; 0.10) than pigs fed the antibiotic-free diet and pigs fed additive supplemented diets (YE, MOS, GLU) tended to show better feed utilization (p = 0.11). There were no significant differences in nutrient digestibilities and carcass traits among treatments.
