The concentrations of functional compounds and micronutrients of chicken breast from native chickens were compared with those from broiler. Totally 200 male chicks from a commercial native chicken (HH) and three newly bred native chicken strains (2A, 2C, and 2D) were reared for about 2 kg of final live weight up to 12 wk. After slaughtered, antioxidant dipeptides, reducing sugar, free amino acids, vitamins, and minerals of the breast muscles were analyzed with those from broilers with similar live weight. Mostly native chicken strains had higher contents of carnosine, anserine, and reducing sugar than the broiler. Especially HH implied the highest values of carnosine and anserine, and 2C did the highest of reducing sugar (p<0.05). Vitamin A contents between native chickens and broiler were not significantly different (p>0.05). The contents of α-tocopherol were significantly higher in 2C than those of HH or broiler (p<0.05). Native chicken strains contained lower cholesterol levels than the broiler. Broiler had higher contents of P, Mg, and Na than native chickens (p<0.05), but it had lower content of Cu than HH or 2A. The savory free amino acids including glutamic acid was highest in 2A than the other native chickens and broiler (p<0.05). This study confirms that certain new strains of native chickens be a good source in terms of functional compounds and micronutrients which can be attractive health promoting nutritional quality factors.
将本地鸡鸡胸肉中的功能化合物和微量营养素浓度与肉鸡的进行了比较。总共200只来自商业本地鸡（HH）和三个新培育的本地鸡品系（2A、2C和2D）的雄性雏鸡饲养至12周龄，最终体重约2千克。屠宰后，分析了鸡胸肉中的抗氧化二肽、还原糖、游离氨基酸、维生素和矿物质，并与体重相似的肉鸡进行比较。大多数本地鸡品系的肌肽、鹅肌肽和还原糖含量高于肉鸡。特别是HH的肌肽和鹅肌肽含量最高，2C的还原糖含量最高（p<0.05）。本地鸡和肉鸡之间的维生素A含量没有显著差异（p>0.05）。2C中的α-生育酚含量显著高于HH或肉鸡（p<0.05）。本地鸡品系的胆固醇水平低于肉鸡。肉鸡的磷、镁和钠含量高于本地鸡（p<0.05），但其铜含量低于HH或2A。包括谷氨酸在内的美味游离氨基酸在2A中含量最高，高于其他本地鸡和肉鸡（p<0.05）。本研究证实，某些新的本地鸡品系在功能化合物和微量营养素方面是良好的来源，这些可成为有吸引力的促进健康的营养品质因素。
