Abstract: One hundred and twenty broilers were randomly divided into 4 groups with 6 replicates in each group and 5 chicken in each replicate. We studied influence on performance and body quality of broiler chicken by using soybean phoshatide to take the place of 0.5%,1% and 1.5% corn of basal daily grain. Conclusion indicated boiler chicken forty-two days adding weight improved 2.1%, 4.4% and 8.7%,feed changing rates raised 3.5%,5.2% and 8.1%, raising costs fell 2.3%,3.5% and 5.8%, chest muscle rates improved 14.7%,0.9% and -0.49%, belly fat rates improved 11.06%,20.28% and 44.75 by using soybean phoshatide to take the place of corn in daily grain. At the same time, one hundred and eighty broilers were randomly divided into 6 groups with 6 replicates in each group and 5 chicken in each replicate. Group A was the control Group, B, C, D, E and F were supplemented with antibiotic, 0.2%, 0.4%, 0.6% and 0.8% bioactive soybean peptide (BSP) respectively. The results showed that the BSP could improve daily weight gain, daily feed intake and slaughter rate, and save feed cost. The study indicated that BSP could be used in broiler production effectively and led to better results than anbiotic. The optimum amount of the supplement was 0.6%.
