摘要
对德昌水牛95头生长发育母牛的体重与体尺指标进行相关分析,得出其体重与胸围、体长的相关系数达到0.9209和0.5788;经逐步回归分析法建立了最优回归方程:体重(y)=-737.381+432.772×胸围+262.598×体斜长,为早期考察德昌水牛生长发育情况提供了依据。
95 Dechang buffalos＇ body weight and body size indexes were collected to analyse its correlation,the results showed that the related coefficient of body weight and chest measurement or body length reached 0.920 9 and 0.578 8 respectively.By regression analysis,we established the optimal regression equation,y=-737.381＋432.772×chest measurement＋262.598×body length,it had provided the basis for early researching Dechang Buffalo.
