摘　　要：为评价九顶山鸡肉质,以便为品种培育和肉品加工利用提供依据,采用国标法测定该鸡种5、6、7月龄组(每组12只,公母各半)以及出栏月龄青脚麻肉鸡(12只,公母各半)腿肌和胸肌蛋白、脂肪、氨基酸及矿物质等肉质成分。结果显示:九顶山鸡腿肌除水分、脂肪、Cu和P外,其他成分各月龄间均有明显变化。其中,粗蛋白、灰分、锌和铁含量5月龄组最高(P<0.01或P<0.05);胸肌中,除水分、铜、铁、锰、和锌外,其他成分各月龄间均有明显变化。其中,粗蛋白和灰分含量5月龄组最高(P<0.01或P<0.05)。不同性别组除锌、锰、Cys、Phe和His外,其他成分在各月龄间含量差异不显著(P>0.05)。九顶山鸡和青脚麻肉鸡腿肌,除水分、磷和铜外,其他成分含量均有明显差异。其中,各月龄组粗蛋白含量前者均高于后者(P<0.01),而粗脂肪含量前者均低于后者(P<0.01)。两品种胸肌间,除水分、磷、铜、铁、锰和锌外,其他成分含量均有明显差异。其中,九顶山鸡粗蛋白含量在5月龄最高(P<0.01)。结论:九顶山鸡肉粗蛋白、粗脂肪、锌和铁优于青脚麻肉鸡;不同性别间大部分肉质成分含量差异不显著;5月龄为九顶山鸡的最适出栏月龄。The purpose of this study was to evaluate the meat quality of Jiudingshan chicken（Gus gallus） in order to provide a basis for breeding and meat processing. The meat compositions including protein, fat, water, ash and mineral substances as well as amino acids in leg muscles and breast muscles of 5, 6, and 7-month-age groups （12 chickens each group, haft male and half female ）of Jiudingshan chicken and fattening green feet chicken group （12 chickens, half male and half female ） were analyzed by GB （Chinese national standards） methods. Except water, fat, Cu and P, the contents of the other compositions in leg muscles of Jiudingshan chicken all were significantly changed with different month ages （P 〈 0.05）. The contents of crude protein, ash, Zn and Fe were highest in the five-month-old group （P 〈 0.01 or 〈 0.05）. Except water, Cu, Fe, Mn and Zn, the contents of the other compositions in breast muscles all were different significantly （P 〈 0.05） among Jiudingshan chickens of different month ages. The contents of crude protein and ash were highest in the five-month-old chicken group （P 〈 0.01 or 〈 0.05）. Except Zn, Mn, Cys, Phe and His, there were no significant differences in the other compositions between different sex groups （P 〉 0.05）. There were significant differences between leg muscles of Jiudingshan chicken and fattening green feet chicken in all the other compo- sitions except water, P and Cu （P 〈 0.01）, in which, the content of crude protein in the former of all the month ages was higher than that in the latter （P 〈 0.01）, but the content of crude fat was reverse. Except water, P, Fe, Mn and Zn, the contents of the other compositions in breast muscle of both the two chicken breeds were different （P 〈 0.01） and the content of crude protein was the highest in the five-month-old group of Jiudingshan chicken. In conclusion, the contents of crude protein, crude fat, Zn and Fe in Jiudingshan chicken are higher than those in green feet chicken an
