摘　　要：京星黄鸡103肉鸡配套系是目前唯一含有北京油鸡血缘的黄羽肉鸡培育品种(配套系)。本研究选取京星黄鸡103肉鸡商品代和纯种北京油鸡各120只(公母各半),比较培育品种和纯种在屠体性能、肉品质和肌肉主要营养成分上的差异。试验鸡同批次孵化出雏,饲养管理条件和饲料营养水平均一致。分别于90和120日龄选取接近各组平均体重的鸡各20只屠宰,检测相关指标。结果表明,京星黄鸡103的生长速度显著快于北京油鸡纯种(P<0.05),其中90日龄平均体重达1.48 kg,120日龄达1.88 kg,分别比纯种的高24.4%和24.5%;90日龄胸肌重和腿肌重比北京油鸡纯种分别提高24.5%和19.2%,120日龄的分别提高了30.7%和28.9%,但两品种间无显著差异(P>0.05);90日龄京星黄鸡103胸肌肌内脂肪和粗蛋白质含量显著高于北京油鸡(P<0.05);胸肌脂肪酸中以硬脂酸和棕榈酸等饱和脂肪酸和花生四烯酸、亚油酸和油酸等不饱和脂肪酸为主,品种之间无显著差异(P>0.05)。综上,京星黄鸡103商品代肉鸡与北京油鸡纯种相比生长速度较快,90日龄达中速型黄羽肉鸡标准,胴体载肉量提升,且基本保持了北京油鸡纯种的肌内脂肪含量高等优良肉品质特性。Jingxing-Yellow 103 is the unique commercial breed(synthetic line)that contains Beijing-You consanguinity by far.In this study,carcass performance,meat qualities and main nutrient content of breast muscle were compared between the synthetic line and pure line.A total of 120 Jingxing-Yellow 103 and 120 Beijing-You pure lines(half male and half female)were incubated and hatched contemporarily,and housed under the same management with the same feed.Each 20 birds with average body weight of the synthetic line and pure line were selected and slaughtered at 90 and 120 days of age,respectively,for the measurement of related traits.As the results showed,Jingxing-Yellow 103 grew faster than Beijing-You pure line.The average body weight of Jingxing-Yellow 103 was 1.48 and 1.88 kg at 90 and 120 days of age,respectively,which was 24.4%and 24.5%higher than those of pure line(P<0.05).The breast muscle and thigh muscle mass was 24.5%and 19.2%increased than the pure line at 90 days of age,and 30.7%and 28.9%at 120 days of age.The breast muscle and thigh muscle yield did not shown significant difference between breeds(P>0.05).The intramuscular fat content and crude protein content of breast muscle in Jingxing-Yellow 103 were higher than those of Beijing-You pure line(P<0.05).The main fatty acid in the breast muscle included saturated fatty acid like stearic acid and palmitic acid,and unsaturated fatty acid like arachidonic acid,linoleic acid and oleic acid.The fatty acid composition was not different between breeds(P>0.05).In all,Jingxing-Yellow 103 showed faster growth and reached the market weight of typical medium type of Yellow-feathered broilers by 90 days,and they had higher muscle mass and basically retained favourable meat quality like high intramuscular fat content as compared to Beijing-You pure line.
