摘　　要：[目的]研究利用活体检测来预测成年蛋鹌鹑屠宰性能的可行性。[方法]以成年栗羽蛋鹌鹑为试验材料,测量其体重、体尺和屠宰性状,应用相关分析方法对3组性状间的相关性进行分析,并建立了回归方程。[结果]栗羽蛋鹌鹑的肉用性能和产肉性能良好,其龙骨长明显高于黄羽鹌鹑,胸肌更发达,屠体重与体斜长、龙骨长、胸宽、胫围和体重的相关系数分别为0.628、0.579、0.497、0.637和0.986,相关性均达到极显著水平(P<0.01)。胸宽和胫围是影响体重的主要指标,分别建立了鹌鹑活重与胫围和胸宽,屠体重与胫围和胸宽,全净膛重与体斜长、胸宽,半净膛重与龙骨长、体斜长和胸宽,腿肌重与胸宽、体斜长、胫围和胫长的回归模型。[结论]通过各性状的相关分析与回归分析,蛋鹌鹑的活体表型性状可用于预测屠宰性能。[Objective]To predict the performance prediction slaughter by detecting the adult quail in vivo.[Method]Adult laying quails were used as test materials to measure body weight,body size and slaughter traits.Relevant analysis principles were used to analyze the correlation between the traits among three groups,and regression equations were established.[Result]The results showed that the meat performance of chestnut quails for egg were good.The keel length of the chestnut quails is obviously higher than that of the yellow quails,and the pectoral muscle was more developed.The correlation coefficients between body weight and body length,keel length,chest width,circumference and body weight were 0.628,0.579,0.497,0.637 and 0.986,respectively,and all the correlation reached extremely significant levels(P<0.01).Regression model were established including the live weight and the circumference and chest width,the weight and the circumference and chest width,the total net weight and body length,chest width,semi-net weight and keel length,body length and chest width,leg muscles,chest width,body length,circumference and length.[Conclusion]Throgh the correlation and regression analysis of various traits,the live phenotypic traits of egg tarts can be used to predict slaughter performance.
