徐海长距鸡体尺性状与屠宰性状间的典型相关分析

为探明徐海长距鸡体尺性状和屠宰性状间的相关关系，在体重接近的情况下随机选取13周龄徐海长距鸡24只（12只公鸡，12只母鸡）进行体尺性能和屠宰性能测定，对各性状进行简单相关分析，并运用典型相关分析对各体尺性状和屠宰性状进行分析。结果表明：徐海长距鸡胫围、胫长、体斜长与大部分性状均呈显著或极显著相关；除肌胃重外其余屠宰性状间均显著或极显著相关。典型相关分析结果表明：徐海长距鸡第一对典型相关系数为0.967，达到了极显著水平，占总相关信息72.6%。在两组性状中起主要作用的为胫长、胸宽、半净膛重、屠体重。本研究结果对徐海长距鸡的早期选育具有一定的参考意义。

Canonical correlation Analysis between Body Measurements and Slaughter Performance of Xuhai Henn Spur Chicken

In order to study the relationship between body measurement traits and slaughter performances of Xuhai Henn Spur Chicken, 24 Xuhai Henn Spur Chicken (12 male, 12 female) of 13 weeks were chosen randomly. Body measurement traits and slaughter performances were measured and analyzed using bivarite correlation analyze and canonical correlation analyze. The results showed that shank girth, shank length and body slanting length had highly significant or significant correlation with most traits. There were highly significant or significant correlation between slaughter performances except muscular stomach weight. The results of canonical correlation analysis showed that the first canonical correlation coefficient between body measurement traits and slaughter performances was 0.967 which explained 72.6 percent of total correlation and was highly significant. The analysis incicated that main traits for the canonical correlation coefficients were shank length, chest width, half-eviscerated weight, carcass weight. The results of the study offered some references for early breeding of Xuhai Henn Spur Chicken.
