| 摘 要： | 对金华母猪初生重、60日龄重、4月龄重、6月龄体长、6月龄胸围、6月龄体高、6月龄膘厚和6月龄重8个生长性状的通径分析和回归分析结果表明：4月龄重、6月龄体长和6月龄胸围对6月龄重有极显著影响。建立最优回归方程为：Y=-39．6286 0．4445x3 0．3753x4 0．3939x5。

| Abstract: | Path analysis and regression analysis were conducted on the eight growth traits that including average pig birth weight (PBW),average pig weaning weight(PWW),pig weight at 4 month (PW4mon),body length(BL),chest circumference(CC),body height(BH),backfats thickness(BF),pig weight at 6 month (PW6mon.)for Jinhua sows.The results showed that PW4mon,BL 6 mon,CC 6 mon have significant influence on PW6mon.The optimum regression equation of growth traits was established also for Jinhua sows.The equation of regression was: y=-39.6286+0.4445x 3+0.3753x 4+0.3939x 5 |
