Abstract: Two thousand and four hundred Cherry valley super-M3 parent stocks at the age of forty weeks were selected and randomly allocated to five treatment groups with three replicates，four diets containing four different compound additives (0.5%，0.2%，0.2% and 0.2%) and basic diet were given to feed these ducks for 42 days in order to study the effects of 4 kinds of compound additives on performance and egg quality in Cherry-valley super-M3 parent stock. The results showed that laying rates were increased with diets of compound additives. When compared to control group，the laying rates of group 1 and group 2 were significantly increased by 1.04% (P<0.05) and 1.97% (P<0.05).The average egg weight of four trail groups were significantly lower than that of control group (P<0.05). The egg-shape index and the percentage of yolk of group 2 was higher than that of control group by 0.05 (P<0.05) and 13.33% (P<0.05). There were significant difference on egg thickness between control group and the first，second and fourth group (P<0.05) except group three. There was significant difference on haugh unit between control group and group 1，2 and 3，and no difference between group 4 and control group. The results indicated that different kinds of compound additives in the duck feed could increase the laying rate and improve egg quality of parent stock.
