The control group of ducks were received a basal diet (BD) without herbal additives, the experimental group I, groupie were fed BD added 1%, 1.5% of Herb I, the experimental group III, group IV were fed BD added 1%, 1.5% of Herb II. The results showed that the contents of serum GsH-Px and the serum SOD levels for all groups were inordinately higher than control group (P < 0.05). The IgA, IgG, IgM, ALB values and TP contents of four  experimental groups had inordinately increased (P < 0.05). Suggesting that Chinese medicinal herbs can improve the immunological indexes and serum level of antioxidant enzymes in Sansui laying duck.
