摘要：

摘要：本文应用相关分析和聚类分析对福建德化黑鸡的体重、体尺性状进行了研究。结果表明，公鸡的体重与体斜长、胸深、胸宽、胸角、龙骨长、胫长和胫围呈显著或极显著正相关，相关程度最大的是体斜长( r =0.796)；而母鸡的体重与胸宽、胸角和胫围呈显著正相关，相关程度最大的是胸宽（r =0.454）。体尺性状对体重的影响及体尺性状间的相关关系随性别的不同而异。体型性状的聚类分析结果表明，公鸡可以聚成4类，母鸡则聚成3类。研究结果为保存、改良和开发利用这一地方鸡种资源提供参考信息。

Abstract:

Abstract: The purpose of this study was to investigate the body type traits, including body weight and body size of Dehua Black Chicken ,a native breed of Fujian, by correlation and cluster analysis. The results indicated that the correlations between body weight and body length, chest depth, chest width, chest angle ,sternum length，shank length ,shank girth ,were significantly positive for the male, and the largest correlation coefficient is body length ( r =0.796). The correlations were also positive significantly between body weight and chest width, chest angle , shank girth for the female. But the largest correlation coefficient is chest width ( r =0.454). With cluster analysis ,body type traits of those chickens were divided into four types in male and three types in female. The results of this study will provide the scientific basis for breeding and improving of the native breed.
