摘　　要：【目的】研究旨在探讨新疆和田地区成年湖羊体尺指标与体重之间的相关性。【方法】随机选取955只成年湖羊,其中公羊464只、母羊491只,测定了体重(Y)以及体高(X1)、体长(X2)、胸围(X3)、管围(X4)等体尺指标。通过SPSS27.0软件,对数据进行了描述性统计、相关性分析和回归分析,并分别建立了公羊和母羊的回归方程。【结果】研究结果表明,新疆和田地区成年湖羊的体高、体长、胸围与体重之间存在极显著正相关关系(P<0.01)。其中,胸围与体重的相关性最为显著,公羊的相关系数为0.770,母羊为0.798;公羊的体高与体重及母羊的管围与体重的相关性不显著。【结论】基于分析结果,公羊的回归方程为Y=0.223X_(1)+0.346X_(2)+0.383X_(3)+0.194X_(4)-13.878,(P<0.01,R^(2)=0.766);母羊的回归方程为Y=0.326X_(1)+0.228X_(2)+0.424X_(3)+0.033X_(4)-7.525,(P<0.01,R^(2)=0.739)。研究所得的回归方程可为新疆和田地区成年湖羊的选育和选种提供科学参考,助力提升湖羊的养殖效益。【Objective】The study aims to explore the correlation between body size indices and body weight of adult Hu sheep in Hotan area,Xinjiang.【Methods】A total of 955 adult Hu sheep were randomly selected,including 464 rams and 491 ewes.Body weight(Y)and body size indices such as body height(X1),body length(X2),chest circumference(X3),and cannon circumference(X4)were measured.Through SPSS 27.0 software,descriptive statistics,correlation analysis,and regression analysis were conducted on the data,and regression equations for rams and ewes were established respectively.【Results】The research results show that there is a highly significant positive correlation between body height,body length,chest circumference and body weight of adult Hu sheep in Hotan area(P<0.01).Among them,the correlation between chest circumference and body weight is the most significant,with the correlation coefficient of 0.770 for rams and 0.798 for ewes;the correlation between body height and body weight of rams and the correlation between cannon circumference and body weight of ewes is weak.【Conclusion】Based on the analysis results,the regression equation for rams is Y=0.223X_(1)+0.346X_(2)+0.383X_(3)+0.194X_(4)-13.878,(P<0.01,R^(2)=0.766);the regression equation for ewes is Y=0.326X_(1)+0.228X_(2)+0.424X_(3)+0.033X_(4)-7.525,(P<0.01,R^(2)=0.739).The regression equations obtained in this study can provide a scientific reference for the breeding and selection of adult Hu sheep in Hotan area,and help improve the breeding efficiency of Hu sheep.
