摘要: 试验旨在揭示威宁鸡体尺和屠宰性状的性别差异情况及体尺与屠宰指标间的相关性,参照中国家禽体尺和屠宰性状测定标准对65只(♀:33;♂:32)180日龄公、母威宁鸡的体尺和屠宰性状进行测定和分析。结果发现,威宁鸡体斜长在公、母鸡之间呈现显著差异,公鸡显著高于母鸡(P< 0.05);冠高和胫长公鸡极显著高于母鸡(P< 0.01),体尺和屠宰性状均呈性别差异,较国内其他地方鸡种,威宁鸡表现出了优异的体形外貌特征,体质健壮,肉用性能好,抗逆性强,其中,公鸡较母鸡表现为体形结构大,肉用性能更佳;另外,威宁鸡各体尺性状、多数屠宰性状及多数体尺与屠宰性状间均呈正相关关系,且多数指标间达到了显著或极显著水平(P< 0.05;P< 0.01),这对今后威宁鸡的选育尤其是早期选育具有重要参考意义。

Abstract: It aimed to investigate the sex differences and correlation of body size and slaughter traits in Wei-ning chicken,the research measured the body size and slaughter traits of 65 Wei-ning chicken(♀:33;♂:32 ) at the age of 180 days according to the nation livestock body size and slaughter measurement standards,and analysis on the correlative between body size and slaughter traits.The results showed that the lean body length was significant difference in the different sex chicken groups (P< 0.05 ),and the cocks were higher than hens,the comb hight and keel bone length of cocks were extremely significant higher than hens (P< 0.01 ).All of the body size and slaughter trait showed difference between cocks and hens,moreover,the Wei-ning chicken also showed excellent appearance,hold the strong body constitution character,good meat performance and adaptability for other native chickens,the body constitution and meat performance of cocks were better than hens.Besides,the different body size,most of slaughter traits and between body size and slaughter traits were positively correlaton,and most of indexes showed the significant or extremely significant correlation levels (P< 0.05;P< 0.01),these data would be crucial insight for the breeding,especial early breeding of Wei-ning chicken.

Key words: Wei-ning chicken; body size; slaughter traits; correlation
