摘要
试验1取10日龄三黄肉鸡175只,随机均分成7组,6个试验组分别在基础日粮中添加0.5%辣椒、1.0%栀子、5.0%青皮、5.0%青蒿、0.5%中药A和0.5%中药B粉,空白对照组饲喂基础日粮。适应期4 d后连续饲喂4周,比较鸡脚部皮肤的颜色和类胡萝卜素含量的变化。结果表明,中药B的增色效果最好,皮肤中类胡萝卜素的含量最高。试验2取10日龄三黄肉鸡75只,随机均分成3组,中药B组在日粮中添加0.5%中药B;化学色素组添加30 mg/kg加丽素黄和10 mg/kg加丽素红;空白对照组饲喂基础日粮。适应期4 d后连续饲喂4周,比较脚、胸和颈部的皮肤颜色和脚、胸部皮肤及血清中类胡萝卜素含量的动态变化。结果表明,中药B组皮肤颜色和组织中类胡萝卜素含量均显著高于化学色素组和空白对照组(P<0.05)。
In experiment one, 175 10-day-old Sanhuang broilers were randomly divided into 7 groups. The chickens in 6 test groups were fed with the feedstuff respectively contained the powder of 0. 5% capsicum, 1% gardenia fruit, 5% green tangerine peel, 5% sweet wormwood, 0. 5% Chinese herbal medicine A （CHM A） and 0. 5% Chinese herbal medicine B （ CHM B） and those in the group of blank control were fed with basic diet for 4 successive weeks after adaptive phase of 4 days. Their color and carotenoids content of foot skin were compared. The results showed that CHM B presented the best color increasing effect and highest carotenoids content in foot skins. In experiment two, 75 10-day-old Sanhuang broilers were divided randomly into 3 groups. The chickens in Chinese herbal medicine group and in chemical pigment group were fed with the diet contained 0. 5% CHM B powder and 30 mg/kg darophyll yellow and 10 mg/kg carphyll red, and the group of blank control were fed with basic diet for 4 successive weeks after adaptive phase of 4 days. The dynamic change on skin color of foot, chest and neck part and carotenoids contents in foot, chest skin and serum were determined. The results indicated that the skin colors and tissue carotenoids contents in CHMB group were markedly higher than those in chemical pigment and blank control group（ P 〈 0. 05 ）.
