Results showed that thymus index and serum IgG levels of broilers were increased obviously by TP(P<0.05), furthermore lymphocyte transformation rate, macrophage activity, percentage of T cell numbers Serum SOD, GSH-Px and CAT activities in broilers were increased obviously by TP at same time(P<0.05)but not to index of fabricius bursa of broilers. Serum MDA levels of broilers were declined obviously by TP(P<0.05).
