中文摘要：为探究信宜怀乡鸡体质量与体尺性状的相关性,测定12周龄信宜怀乡鸡的体质量、体尺性状,进行相关性分析和聚类分析。相关性分析结果显示,公鸡体质量与体斜长、龙骨长、胫长呈显著或极显著正相关,相关程度最大的是体斜长(r=0.996);母鸡的体质量与胫长、体斜长、龙骨长、胸深呈显著或极显著正相关,相关程度最大的是胫长(r=0.990)。以上结果表明,怀乡公、母鸡在体型选育过程中,参考的体尺性状不同。聚类分析结果显示,公鸡可以聚成4类,母鸡则聚成3类,公鸡体型性状中重要的代表性状为体斜长、龙骨长、体质量和胸宽,母鸡为体质量、体斜长和龙骨长。

外文摘要：The aims of this study was to investigate the relationships among the body type traits,including body weight and body size of 12 weeks old Xinyi Huaixiang chicken by correlation and cluster analysis. The results indicated that the correlations between body weight and body length,body diagonal length,shank length were significantly positive for the male,and the largest correlation coefficient was body length（ r = 0. 996）. The correlations were also significantly positive between body weight and body diagonal length,body length,shank length,chest deep for the female. But the largest correlation coefficient was shank length（ r = 0. 990）. It demonstrated that Huaixiang chicken breeding processes in body type had different reference of body size traits between the sexes. With cluster analysis,body type traits of those chickens were divided into four types in male and three types in female. The representative body traits of the male included body weight,body length,body diagonal length and chest width. The representative body traits of the female included body weight,body length and body diagonal length.
