In order to research of Chinese herbal medicine additive Jin Ling white duck egg production performance and the influence of the serum biochemical indicators,240 200 day old Jinling white ducks were randomLy divided into 4 groups:control group D and experimental groups S1,S2,and S3.The experimental groups were supplemented with 1%,1.5%and 2%Chinese herbal additives in the basic diet,and started the 60-day experiment after one week of pre-feeding.At the end,the changes of serum immune protein,blood antioxidant index,blood lipid index,egg production and egg quality of Jinling white ducks were measured.Results show that compared with the control group,experimental group of immunity and oxidation resistance index increased significantly,lipid decreased significantly;In terms of egg production performance,the daily egg production rate and egg weight of Jinling White Duck in the experimental group were significantly higher than those in the control group,while the rate of broken eggs was significantly lower.Chinese herbal additives can enhance the immunity and antioxidant capacity of Jinling white ducks,improve egg production performance,and adding 2%Chinese herbal additiveshas the better effect.
