Effects of bioactive soybean peptide as feed additive on performance of broiler chicken

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%.
