摘要
运用SAS软件分析了河南大尾寒羊体尺与体重间的表型相关,体尺对体重的直接和间接影响,并建立了最优回归模型。研究结果表明,体高和胸围是影响大尾寒羊体重的最主要体尺因素,应在选择河南大尾寒羊体重的同时,加强对体高和胸围的选择力度。
The phenotype correlation between body size and body weight,the direct and indirect effect of body size on body weight of Henan's large-tail sheep were analyzed with SAS software,and the optimum regression equation was established subsequently.The results indicated that body weight and chest girth were the major body size factors affecting the body weight of Henan's large-tail sheep.Therefore,besides body weight selection,the body height and chest girth selection should be strengtheaed at the same time.
