雷州黑鸭体尺性状与屠宰性状间的典型相关分析

为研究雷州黑鸭体尺性状和屠宰性状之间的关系。随机选取60只（公、母各半）300日龄雷州黑鸭进行体尺测量和屠宰试验，进行典型相关分析。结果表明：雷州黑鸭体尺性状和屠宰性状间大部分指标间都达到极显著或显著性水平的正相关（P＜0.01或P＜0.05），少部分的指标间的相关性为负相关。典型相关分析结果为：雷州黑鸭体尺性状与屠宰性状间的第1~2对典型相关系数为0.767、0.729，分别达到了极显著性水平(P＜0.01)和显著性水平(P＜0.05)，分别占两组性状总相关信息的42.5%、33.7%。在两组性状中起主要作用的为体斜长、胫围、半净膛重和全净膛重。

Canonical Correlation Analysis between Body Measurements and Slaughter Performance in Leizhou Black Ducks

In order to study the relationship between body measurements and slaughter performance of Leizhou Black Ducks. Sixty （half was male, half was female） Leizhou Black Ducks which were 300-days-old were selected randomly for body measurements and slaughter test and canonical correlation analysis. The results showed that： most of these quotas in body measurements traits and slaughter performance had a extremely significant or significant positive correlation of Leizhou Black Ducks （P〈0.01 or P〈0.05）, only a small part of these quotas had a negative correlation, the results of canonical correlation analysis showed that the first and second canonical correlation coefficients between body measurement traits and slaughter traits were 0.767 （P〈0.01） and 0.729 （P〈0.05）, they expressed 42.5% and 33.7% of total correlation, respectively. The analysis indicated that main traits for the canonical correlation coefficients were body slanting length, shank girth, the weight of eviscerated yield with giblet and the weight of whole net carcass.
