摘　　要：本试验旨在研究饲粮硒和维生素E添加水平对樱桃谷种鸭产蛋性能和蛋品质的影响。选取健康的50周龄樱桃谷种鸭6480只，随机分为6个组，每组4个重复，每个重复270只（其中母鸭220只，公鸭50只）。采用2×3两因子试验设计配制6种试验饲粮，饲粮中硒的添加水平分别为0．125、0．250mg／kg，维生素E的添加水平分别为50、100、200mg／kg。试验期为17周（50～66周龄）。结果表明：1）饲粮硒和维生素E添加水平对樱桃谷种鸭产蛋率和受精率均有显著影响（P〈0．05），而对合格蛋率、受精率、受精蛋孵化率、健雏率和蛋重均无显著影响（P〉0．05）。相比低硒（0．125mg／kg）组，高硒（0．250mg／kg）组的产蛋率和受精率显著提高（P〈0．05）；100mg／kg维生素E组的产蛋率和受精率显著高于50mg／kg维生素E组（P〈0．05），与200mg／kg维生素E组差异不显著（P〉0．05）。饲粮硒和维生素E添加水平的交互作用对樱桃谷种鸭产蛋性能的影响不显著（P〉0．05）。2）饲粮硒添加水平对樱桃谷种鸭蛋壳厚度有显著影响（P〈0．05），而对蛋比重、蛋壳重、蛋黄比率、蛋黄颜色、哈氏单位和蛋壳强度无显著影响（P〉0．05）。饲粮维生素E添加水平对樱桃谷种鸭蛋壳厚度、蛋黄比率和蛋黄颜色有显著影响（P〈0．05），而对蛋比重、蛋壳重、哈氏单位和蛋壳强度无显著影响（P〉0．05）。饲粮硒和维生素E添加水平的交互作用对樱桃谷种鸭蛋壳重和蛋壳强度的影响显著（P〈0．05）。其中，高硒（0．250mg／kg）和高维生素E（200mg／kg）组的蛋壳重和蛋壳强度最大。综上，本试验条件下，樱桃谷种鸭饲粮中添加0．250mg／kg硒和200mg／kg维生素E时可获得较佳的产蛋性能和蛋品质。This experiment was conducted to study the effects of dietary selenium and vitamin E supplemental levels on laying performance and egg quality of Cherry Valley breeding ducks. A total of 6 480 healthy Cherry Valley breeding ducks aged 50 weeks were randomly divided into 6 groups with 4 replicates per group and 270 ducks per replicate （including 220 female ducks and 50 male ducks）. Seven experimental diets were designed by using a 2 ×3 two-factor experimental design with 2 selenium supplemental levels （0. 125 and 0. 250 mg/kg） and 3 vitamin E supplemental levels （50, 100 and 200 mg/kg）. The experiment lasted for 17 weeks （50 to 66 weeks of age）. The results showed as follows： 1 ） both dietary selenium and vitamin E sup- plemental levels had significant effects on laying rate and fertilization rate （ P 〈 0.05）, while had no significant effects on qualified egg rate, fertilization rate, fertilization egg hatching rate, healthy chicken rate and egg weight （P 〉 0.05 ）. Compared with low selenium （0. 125 mg/kg） group, the laying rate and fertilization rate in high selenium （0. 250 mg/kg） group were significantly increased （P 〈0.05）. Ducks in 100 mg/kg vita- min E group had significantly higher laying rate and fertilization rate than those in 50 mg/kg vitamin E group （P 〈 0.05 ）, while which had no significant difference compared with ducks in 200 mg/kg vitamin E group （ P 〉 0.05 ）. The interaction effect of selenium and vitamin E supplemental levels had no significant effect on laying performance （ P 〉 0.05）. 2 ） Dietary selenium supplemental level had a significant effect on eggshell thickness （P 〈 0.05）, while had no significant effects on egg proportion, eggshell weight, yolk ratio, yolk color, Haugh unit and eggshell strength （P 〉 0.05 ）. Dietary vitamin E supplemental level had significant effects on eggshell thickness, yolk ratio and yolk color （P 〈 0.05 ）, while had no significant effects on egg proportion, eggshell weight, Haug
