Abstract: 300 meat-miscellaneous chicken of 1 day are divided into 3 groups randomly. They are comparison, test 1, test 2. It is 5 repetitions of 20 chickens each. The meat-miscellaneous chickens are immunised by routine. The feed with compound Chinese traditional medicine powder has effects on the weight and immunity of meat-miscellaneous chicken. The results indicate that the difference of antibody of NDV in test 1 and test 2 is obvious in 14, 21 d (P<0.05), not obvious in 3 groups in 28, 35 d (P>0.05). The powder has good effects on meat-miscellaneous chicken in NDV; test 1 and test 2 is obvious in IBDV antibody in 21 d (P<0.05), not obvious in 28, 35 d. The immune indexes indicate that the test group is higher than the contrast (P<0.05). It shows that it strengthens body fluid immunity with compound Chinese traditional medicine powder.
