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 -2.5%, belly fat rates improved 11.06%,20.28% and 44.75 by using soybean phoshatide to take the place of corn in daily grain.
