| 摘 要： | 将360只48周龄“尼克红”蛋鸡随机分为5组，每组设3个重复，每个重复24只。试验1组为玉米基础日粮组，试验2组为小麦型基础日粮组（0．10％酶制剂组），试验3组为0．10％酶制剂组＋0．5％叶黄素添加剂，试验4组为0．10％酶制剂组＋1．0％叶黄素添加剂，试验5组为0．10％酶制剂组＋1．5％叶黄素添加剂。预试期7天，试验期21天。结果表明，添加1．5％的叶黄素添加剂可以显著改善鸡蛋的蛋黄颜色。与小麦对照组相比，蛋黄颜色提高了188．33%（P〈0．05）。与玉米基础日粮组相比，日粮添加1．5%叶黄素添加剂组鸡蛋蛋黄颜色提高了0．82％，但差异不显著（P〉0．05），添加叶黄素添加剂对鸡蛋的蛋重、蛋比重、蛋形指数影响不大。

| Abstract: | Three hundred and sixty laying hens were divided into five treatment groups randomly, each of which included three replicates of 24 hens. Treatment Ⅰ was corn--based diet treatment, Treatment Ⅱ was wheat--based diet treatment（0. 10% enzymes treatment） , treatment Ⅲ was 0. 10% enzyme treatment ＋0. 5% vitelline colorant and treatment Ⅳ was 0. 10% enzyme treatment ＋1.0% vitelline colorant , treatment Ⅴ was 0. 10% enzyme treatment ＋1.5% vitelline colorant. The results of feeding trail showed that adding 0. 10% enzymes to wheat--based diets greatly improved laying hens production performance, but there was little lutein in wheat. When laying hens were fed wheat--based diets , the color of egg yolk decreased and turned pale. The result showed that adding 1.5% vitelline colorant to 0. 10% enzyme treatment could improve the color of egg yolk greatly. Compared with wheat--based diet treatment, 1.5 % vitelline colorant treatment increased the color of egg yolk by 188. 33% （ P 〈0. 05 ）. Compared with cornbased diet treatment, 1.50% vitelline colorant treatment increased the color of egg yolk： by 0. 82%（ P〉0. 05 ）, and had little effect on egg weight and egg--shape index. |
