The astragalus, orange peel, garlic and white atractylodes rhizome were used to be made into compound preparation which was added into the daily diet of broilers by 1%. The results showed that at each raising stage the difference of BWG of experimental group was significant than that of the control (P<0.05), the Differences of decrease of F/G were all significant (P<0.05). In the whole experimental period the mortality of experimental group decreased by 71.43% than the control. The profit benefit of the experimental group increased by 46.67% than the control, and the European benefit index by 45.45%. It showed that the Chinese herb preparation can improve the productive performance of broilers, enhance the disease resistance effect and shows obvious economic benefit.
