摘　　要：为探索来凤酉水鸡种质资源特性,研究了生态养殖模式下来凤酉水鸡资源肌肉氨基酸含量与风味,并比较分析了其与江汉鸡等3个地方鸡品种肌肉营养及风味差异。结果表明,来凤酉水鸡公鸡、母鸡肌肉中均检测到17种氨基酸,含量最高的氨基酸是谷氨酸,分别为3.88 g/100 g、3.84 g/100 g,EAA/TAA分别为43.07%、44.86%,EAA/NEAA分别为75.60%、81.36%,达到FAO/WHO规定的理想氨基酸标准。来凤酉水鸡公鸡、母鸡肌肉中谷氨酸的TAV最大,分别为12.93、12.80,呈味最强。湖北省4个地方鸡品种资源公鸡肌肉中EAA含量差异不显著,母鸡肌肉中EAA含量存在不同程度的差异;公鸡肌肉中,洪山鸡TAA最高,为(23.70±1.91)g/100 g,然后依次是来凤酉水鸡[(22.8±2.25)g/100 g]、江汉鸡[(19.01±0.75)g/100 g]、双莲鸡[(18.87±1.56)g/100 g],品种间差异不显著;母鸡肌肉中,来凤酉水鸡的TAA最高,为22.67 g/100 g,显著高于江汉鸡等3个品种,随后依次为洪山鸡(20.05 g/100 g)、江汉鸡(18.78 g/100 g)、双莲鸡(17.49 g/100 g),洪山鸡显著高于双莲鸡。以公鸡、母鸡肌肉氨基酸为指标进行聚类,洪山鸡均独立形成一大类。In order to explore the characteristics of Laifeng Youshui chicken germplasm resources,the content and flavor of amino ac⁃ids in the muscle of Laifeng Youshui chicken resources under the ecological breeding mode were studied,and the differences in mus⁃cle nutrition and flavor between it and three local chicken breeds such as Jianghan chicken were compared and analyzed.The results showed that:17 kinds of amino acids were detected in the muscle of Laifeng Youshui cock and hen.Among them,glutamic acid had the highest content,3.88 g/100 g and 3.84 g/100 g respectively.The EAA/TAA values were 43.07%and 44.86%respectively,and the EAA/NEAA values were 75.60%and 81.36%respectively,which reached the ideal amino acid standard specified by FAO/WHO.It was calculated that the muscle TAV of Laifeng Youshui chicken was the largest,and the TAV of glutamic acid was 12.93 and 12.80,respectively,which had the strongest flavor.There was no significant difference in EAA content in male chicken muscle among the four local chicken breeds in Hubei Province,but there was a difference in EAA content in female chicken muscle to different degrees;Among the cock muscles,Hongshan chicken had the highest TAA of(23.70±1.91)g/100 g,followed by Laifeng Youshui chicken[(22.8±2.25)g/100 g],Jianghan chicken[(19.01±0.75)g/100 g],and Shuanglian chicken[(18.87±1.56)g/100 g],but there was no significant difference among varieties;among the hen muscles,Laifeng Youshui chicken had the highest TAA,22.67 g/100 g,which was significantly higher than the other three breeds,followed by Hongshan chicken(20.05 g/100 g),Jianghan chicken(18.78 g/100 g),Shuanglian chicken(17.49 g/100 g),and Hongshan chicken was significantly higher than Shuanglian chicken.The muscle amino acids of cocks and hens were used as indicators for clustering,and Hongshan chicken formed a group independently.
