摘要： [目的]解析白羽王鸽屠宰性能与体尺性状的关联性,为今后在贵州地区科学系统地培养白羽王鸽积累参考数据。[方法]对30日龄白羽王鸽的体尺和屠宰性能指标进行了测定,并对测定指标进行显著性检验和相关性分析。[结果]白羽王鸽在30日龄时具有较高的屠宰率（87.200%）,平均活重（429.960±51.781）g,全净膛重（319.253±40.342）g,全净膛率74.610%,具有较好的肉用性能。白羽王鸽屠宰性能和体尺性状的相关分析结果显示,白羽王鸽胫长、活重和屠宰重与体斜长具有显著（P<0.05）相关性,翅重与体斜长极显著（P<0.01）相关;龙骨长与胸深、胸宽、全净膛重、胸肌重呈现极显著（P<0.01）正相关;胸深与胸宽极显著（P<0.01）正相关,与胫围极显著（P<0.01）负相关,与活重、屠宰重、胸肌重和腿肌重呈现显著（P<0.05）正相关;屠宰重、全净膛重、胸肌重、腿肌重、头重和翅重与活重呈现极显著（P<0.01）正相关;全净膛重、胸肌重、腿肌重、头重、翅重与屠宰重呈现极显著（P<0.01）正相关。该研究设立了白羽王鸽屠宰性能与体尺性状之间的多元回归方程,同时对白羽王鸽活重、屠宰重、全净膛重、胸肌重和腿肌重与体斜长、龙骨长、胫长和胫围分别建立了回归模型,模型拟合度F检验均达显著或极显著水平。[结论]以上研究结果可为白羽王鸽的相关研究提供参考。

Abstract: [Objective]To assess the correlation between slaughter performance and body size traits of white feather king pigeon, and to provide referential data for scientific and systemic rearing of white feather king pigeon in Guizhou area. [Method]The indicators of body size and slaughter performance of 30-day-old white feather king pigeons were determined, and significance test and correlation analysis of the tested indicators were carried out. [Result] At the age of 30 days, the white feather king pigeons had a relatively higher dressing rate （87.200%）, and their average live weight, eviscerated weight and eviscerated rate were （429.960±51.781） g, (319.253±40.342) g and 74.610%, respectively, indicating a good meat performance. The correlation analysis demonstrated that shank length, live weight and slaughter weight had significant （P<0.05） correlation with body oblique length, and wing weight had extremely significant （P<0.01） correlation with body oblique length; keel length was extremely significantly （P<0.01） positively correlated with chest depth, chest width, eviscerated weight and chest muscle weight; chest depth was extremely significantly （P<0.01） positively correlated with chest width, extremely significantly （P<0.01） negatively correlated with shank girth, and significantly （P<0.05） positively correlated with live weight, slaughter weight, chest muscle weight and leg muscle weight; slaughter weight, eviscerated weight, chest muscle weight, leg muscle weight, head weight and wing weight were extremely significantly （P<0.01） positively correlated with live weight; eviscerated weight, chest muscle weight, leg muscle weight, head weight and wing weight were extremely significantly （P<0.01） positively correlated with slaughter weight. A multivariate regression equation between slaughter performance and body size traits of white feather king pigeon was established. In addition, the regression models for live weight, slaughter weight, eviscerated weight ,chest muscle weight and leg muscle weight with body oblique length, keel length, shank length and shank girth were established, respectively, and the model fitting degree reached significant or extremely significant levels by F test. [Conclusion] The results obtained in this study provides scientific data for the future researches of white feather king pigeon.
