| Abstract: | 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. |
