Study on Compound Astragalus Prescription Preparation Improving Productive Performance and Disease-resistance of Meat Chicken

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.
