摘　　要：本试验旨在研究小麦-豆粕型饲粮中添加不同水平金菊黄和一品红对黄羽肉鸡生长性能,背部皮肤、腹部皮肤、胫脚和腹脂颜色以及色素沉积基因表达的影响,为天然类胡萝卜素在肉鸡上的应用提供参考。选取540只健康状况良好且体重相近的1日龄麻黄肉公鸡,随机分为3组,每组6个重复,每个重复30只鸡。对照组饲喂基础饲粮,色素1组在基础饲粮中添加1000 mg/kg金菊黄和1000 mg/kg一品红,色素2组在基础饲粮中添加2000 mg/kg金菊黄和2000 mg/kg一品红。试验期48 d。结果表明:1)色素1组48日龄体重以及22~48日龄和1~48日龄平均日增重均显著高于对照组(P<0.05),色素1、2组22~48日龄和1~48日龄料重比显著低于对照组(P<0.05)。2)对于背部皮肤,与对照组相比,色素2组21日龄亮度(L^(∗))值显著降低(P<0.05),色素1、2组屠宰后45 min L^(∗)值显著降低(P<0.05);色素2组35日龄红度(a^(∗))值显著升高(P<0.05),色素1、2组屠宰后45 min和48 h a^(∗)值均显著升高(P<0.05);色素1、2组21、35、48日龄以及屠宰后45 min和48 h黄度(b^(∗))值均显著升高(P<0.05),且色素2组21、35和48日龄b^(∗)值显著高于色素1组(P<0.05)。3)对于腹部皮肤,与对照组相比,色素2组屠宰后45 min和48 h L^(∗)值显著降低(P<0.05);色素1、2组21日龄、48日龄以及屠宰后45 min和48 h a^(∗)值显著升高(P<0.05),且色素2组21日龄a^(∗)值显著高于色素1组(P<0.05);色素1、2组21、35、48日龄以及屠宰后45 min和48 h b^(∗)值均显著升高(P<0.05),且色素2组21日龄和屠宰后48 h b^(∗)值显著高于色素1组(P<0.05)。4)对于胫脚,与对照组相比,色素1、2组35日龄L^(∗)值显著降低(P<0.05);色素1、2组21、35和48日龄a^(∗)值显著升高(P<0.05);色素1、2组21、35和48日龄b^(∗)值显著升高(P<0.05),且色素2组35和48日龄b^(∗)值显著高于色素1组(P<0.05)。5)对于腹脂,与对照组相比,色素1、2组48日龄a^(∗)和b^(∗)值均显�This study was conducted to investigate the effects of different levels of goldenrod and poinsettia added to the wheat-soybean meal diet on growth performance,color of back skin,abdominal skin,tibial and abdominal fat and pigment deposition gene expression of yellow-feathered chickens,to provide reference for the application of natural carotenoids in chickens.A total of 540 healthy one-day-old ephedra male chickens with similar body weight were randomly divided into 3 groups with 6 replicates per group and 30 chickens per replicate.Chickens in the control group were fed a basal diet,chickens in pigment 1 group were fed the basal diet supplemented with 1000 mg/kg goldenrod and 1000 mg/kg poinsettia,and chickens in pigment 2 group were fed the basal diet supplemented with 2000 mg/kg goldenrod and 2000 mg/kg poinsettia.The experiment lasted for 48 days.The results showed as follows:1)the body weight at 48 days of age and average daily gain during 22 to 48 days of age and 1 to 48 days of age of pigment 1 group were significantly higher than those of the control group(P<0.05),and the feed to gain ratio during 22 to 48 days of age and 1 to 48 days of age of pigment 1 and 2 groups was significantly lower than that of the control group(P<0.05).2)For back skin,compared with the control group,the brightness(L^(∗))value at 21 days of age of pigment 2 group was signifi-cantly decreased(P<0.05),and the L^(∗)value of pigment 1 and 2 groups at 45 min after slaughter was signifi-cantly decreased(P<0.05);the redness(a^(∗))value at 35 days of age of pigment 2 group was significantly in-creased(P<0.05),and the a^(∗)value at 45 min and 48 h after slaughter of pigment 1 and 2 groups was signifi-cantly increased(P<0.05);the yellowness(b^(∗))value at 21,35,48 days of age and 45 min and 48 h after slaughter of pigment 1 and 2 groups was significantly increased(P<0.05),and the b^(∗)value at 21,35 and 48 days of age of pigment 2 group was significantly higher than that of pigment 1 group(P<0.05).3)For ab-dominal skin,compared
