摘　　要：[目的]分析成年巴特肯羊的体尺指标与体重的相关性。[方法]以2~3岁成年巴特肯羊为研究对象,通过测量巴特肯羊的体重、体高、体长、胸围等体尺性状,并对各性状间的相关性进行了分析,探究了与成年巴特肯羊体重密切相关的体尺指标,根据体长、胸围和管围建立了成年巴特肯羊体重的最优回归模型。[结果]影响成年巴特肯公羊体重的主要体尺指标为胸围和体长,且体重与胸围和体长呈极显著正相关(P<0.01)。巴特肯母羊的主要体尺指标为胸围和管围,且体重与胸围和管围呈极显著正相关(P<0.01)。巴特肯公羊体重估算公式为Y(体重)=0.681X_(2)(体长)+0.282X_(3)(胸围)+0.652X_(4)(管围)-5.109。巴特肯羊母羊体重估算公式为Y(体重)=3.69X_(4)(管围)+0.253X_(3)(胸围)-5.81。[结论]该试验结果可用于相关领域实际生产过程中成年巴特肯公羊和母羊体重的估算。[Objective]To analyze the correlation between body size indices and body weight of adult Bartken Sheep.[Method]Taking 2-3 year-old adult sheep as the research object,the body weight and body height,body length,chest circumference,other body size indices of Bartken Sheep were measured.And the correlation between the traits was analyzed.The body size indices closely related to the body weight of adult Bartken Sheep were explored.According to body length,chest circumference and shank circumference,the optimal regression model of the body weight of adult Bartken Sheep was established.[Result]The main body size indices affecting the body weight of adult Bartken rams were chest circumference and body length,and there was an extremely significant positive correlation between body weight and chest circumference,body length(P<0.01).The main body size indices of Bartken ewes were chest circumference and shank circumference,and there was an extremely significant positive correlation between body weight and chest circumference and body length(P<0.01).The estimation formula for the body weight of Bartken ram was Y(body weight)=0.681 X_(2)(body length)+0.282 X_(3)(chest circumference)+0.652 X_(4)(tube circumference)-5.109.Estimation formula for the body weight of Bartken ewe was Y(body weight)=3.69 X_(4)(tube circumference)+0.253 X_(3)(chest circumference)-5.81.[Conclusion]The results of this experiment could be used to estimate the body weight of adult Bartken rams and ewes in the actual production process.
