摘　　要：选取40周龄的樱桃谷SM3父母代种鸭2400只,随机分成5组,在1～4组的基础日粮中分别加入0.5%、0.2%、0.2%和0.2%的4种复合添加剂,第5组饲喂基础日粮。试验期为42 d。研究4种复合添加剂对樱桃谷种鸭的生产性能和蛋品质的影响。结果表明,添加复合添加剂可以提高樱桃谷种鸭产蛋率,第1组和第4组产蛋率分别高出对照组1.04%(P<0.05)和1.97%(P<0.05);4个试验组的平均蛋重均低于对照组(P<0.05)。第2组的蛋形指数和蛋黄比率分别比对照组高0.05(P<0.05)和13.33%(P<0.05)。对照组与第1、2和4组的蛋壳厚度之间差异显著(P<0.05),与第3组之间差异不显著(P>0.05)。对照组的哈氏单位与第4组差异不显著(P>0.05),与第1、2、3组之间差异显著(P<0.05)。在种鸭日粮中添加复合添加剂可以提高种鸭的产蛋率和改善种鸭的蛋品质。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.
