According to the two experiments by the orthogonal design L9(34),the optimum levcl of methionlne-Cu,Fe, Zn and Mn complex was chosen in the formula feed of laying ducks. The composition was Cu 3mg/kg, Fu 20mg/kg,Zn 60mg/kg and Mn 55mg/kg. The effect on the laying and meat duck’s growth was tested in this same level,and adding inorganic salt as control. The results showed that: 1)In the trial of laying ducks, the egg production rate and feed conversion were increased by 10.82% and 10.67% respectively(P0.01),compared with the control group. 2)In the trial of meat ducksk, the feed conversion was increased by 5.35% and the weight gain of male and female meat ducks were increased by 2.02% and 12.90% respectively,compared with the control.It was suggested that methionine Cu, Fe, Zn and Mn complex compound could be used as an ideal feed additive to inprove laying performance,growth performance and feed conversion of ducks.
