In 300mg/kg JSS treatment, the yolk color was 6 degree too. While added 500mg/kg JMH into the basal diet, the egg yolk color was up to 9 degree. Supplement of oxytetracycline + JMH or chlortetracy dine + JMH in the basal diet, the egg yolk color was up to 8 and 6 degree respectively and decreased one and three color unit respectively than that of JMH treatment. Added oxytetracyclimne + JSS or chlortetracycline + JSS, the egg yolk color was up to 8 and 6degree respectively. When added arsanilic acid + JSS, the egg yolk color was up to 7 degree and improved one color unit than that of JSS treatment. When added arsanilic acid +JMH to basal diet, the egg yolk color was up to 8 degree and decreased one color unit than that of JMH treatment.

饲料中添加300mg/kg的金闪闪，蛋黄颜色也是6级，没有产生增色效果，添加500mg/kg的加美黄，可使蛋黄颜色达到9级，提高3个比色单位，土霉素与加美黄配合使用，蛋黄颜色为8级，比加美黄组降低1级，金霉素与加美黄配合使用蛋黄颜色为6级，比加美黄组降低3级，土霉素与金闪闪配合使用可使蛋黄颜色升到8级，比金闪闪组提高2级，金霉素与金闪闪配合使用蛋黄颜色仍为6级，阿散酸与金闪闪配合使用，蛋黄颜色为7级，比金闪闪组提高1级，阿散酸与加美黄配合使用蛋黄颜色为8级，比加美黄组降低1级。
