白羽王鸽体尺与屠宰性能的相关及回归分析

以21日龄的白羽王鸽为材料,测量体重、体尺和屠宰性状,应用典型相关分析原理对3组性状间的相关关系进行分析研究,并建立了回归方程。结果表明:屠体重与体斜长、龙骨长、胸深、胸宽、胫长和活重相关系数分别为0.646、0.457、0.560、0.478、0.577、0.947,所有相关系数均达到极显著水平(P<0.01)。分别建立白羽王鸽活重与体斜长、胸宽和胫长,屠体重与体斜长、胸深,全净膛重与体斜长、龙骨长、胸宽,半净膛重与体斜长、胸宽、胫长的回归模型。通过各性状的相关与回归分析,可以间接估计其生产性能,从而简化对肉鸽生产性能的测定过程,加速育种进程。为利用白羽王鸽的体尺性状预测屠宰性能提供理论依据。

Correlation and Regression Analysis on Slaughter Performance and Body Size of White Wing Pigeon

Fifty 21-day-old white wing pigeons were used to measure their body weight,body size and slaughter performance indexes and then study these data with correlation and regression analysis.The correlation coefficients among body weight,body size and slaughter performance indexes were analyzed.The correlation coefficients between slaughter body weight and body slanting length,keel length,chest depth,chest width,shank length,body weight were 0.646,0.457,0.560,0.478,0.577,0.947 respectively(P<0.01).Some regression equations were also constructed.
