摘　　要：试验选取400日龄海兰灰蛋鸡224只，随机分为4组，每组4个重复，每个重复14只，I组为对照组，其余3组在基础日粮的基础上分别添加1、2、4g／kg金盏菊提取物分别设为试验Ⅱ、Ⅲ、Ⅳ组，试验期14天，研究金盏菊提取物对蛋黄着色效果的影响。试验结果显示：蛋黄颜色自第2天起，各试验组与对照组相比逐渐加深，在试验第5天，试验组Ⅲ、Ⅳ的蛋黄颜色达到显著水平（P〈0．05），到第8天达到极显著水平（P〈0．01）；其中添加金盏菊提取物剂量达到2g／kg时，蛋黄颜色极显著加深（P〈0．01）。224 400 -day -old Hyline layers were randomly allocated to four treatments, with four replicates in each treatment and four hens in each replicate, and fed with basal diets mixed 0g/kg, lg/kg, 2g/kg, 4g/kg Calendula officinalis L. respectively. Experimental period was 14 days. The different additions were studied on the effect of egg yolk color. The result showed as follows： from the second day, yolk color of test groups increased gradually. On day 5 and 8, the difference between 2g/kg or 4g/kg addition and the control group reached to signinficant （ P 〈 0.05 ） and extremely significant （ P 〈 0.01 ） respectively, especially when addition was 2g/kg , yolk color increased significantly （ P 〈 0.01 ）.
