Abstract: Effects of Periplaneta americana on breast meat qualities of broilers were studied.396 male broilers at one-day old were randomly allotted to control group fed with basal diet and three treatment groups fed with Periplaneta americana of 2.0%,1.0% and 0.5%,replacing fish meal in basal diet.There were three replicates with 33 broilers in each group,The experiment was lasted for 70 days.The results showed that significant differences are not observed in pH,drip loss,cooking loss and shear force of breast meat among all groups(P>0.05),there is a tendency of decrease in these indexes as Periplaneta americana is increased in diet(P>0.05).
