摘要
研究在日粮中添加含天然色素的玉米和人工色素的加丽素红对AA肉仔鸡皮肤和脚胫颜色的影响。结果表明:AA肉仔鸡饲喂含天然色素的玉米和含人工色素的加丽素红的日粮都能改善AA肉仔鸡皮肤、脚胫颜色。人工色素组,随着加丽素红添加量的提高,各处理的RCF值提高,30mg/kg、60mg/kg组RCF值较对照组提高显著(P<0.05)。天然色素组,试验前期随着玉米添加量的提高,各处理的RCF值提高,50%、70%玉米组较对照组提高显著(P<0.05)。人工色素组加丽素红添加量为60mg/kg时,AA肉仔鸡皮肤和脚胫的RCF值与天然色素组日粮中玉米添加量为50%的着色程度一致。试验后期,人工色素组玉米添加量均为30%的处理1、处理2与天然色素组玉米添加量为30%的处理6AA肉仔鸡皮肤和脚胫的RCF值保持一致。
A trial was carried on to compare the effects of natural pigment （maize） and artificial pigment （carophyll red） in diets on the color of skin and shank skin in broilers. The results showed that： AA broilers fed maize containing natural pigment or artificial pigment （carophyll red） in diets could improve the color of skin and shank skin. In artificial pigment group, with the increasing earophyll red, the RCF value increased. When adding carophyll red of 30 mg/kg or 60 mg/kg, the RCF value had significant difference （P〈0.05） compared with the control group. In the first period of the experient in natural pigment group, with the increasing maize, the RCF value of every treatment had increased too. When adding 50% （w/w） or 70% （w/w）maize, the RCF value had significant difference （P〈0.05） compared with the control group. Adding carophyll red of 60 mg/kg, RCF value of skin and shank skin was consistent with that of adding 50% （w/w） maize in diets; In the late experi- ent period, RCF value of skin and shank skin of treatment one, two in artificial pigment group was consistent with that of treatment six that adding 30% （w/w） maize.
