| 根据蒙城本地黄牛、秦本F1代、西本F1代（秦：秦川牛；西：西门塔尔牛；本：蒙城本地黄牛）及豫北黄牛、本夏利F2代和本夏西F2代（本：豫北黄牛；夏：夏洛来牛；西：西门塔尔牛）的体尸体重资料，运用生物统计方法对黄牛活重进行了四元回归分析，并建立了黄牛活重估测的四元回归方程。 |

| Estimating yellow cattle's liveweight by using four factors regression |
|
|
| Abstract: |
| The four factors regression method was used to anylize the data of body measurments (height at withers,body length,heart girth and circamference of cannon bone) and liveweight of yellow cattle,which includes Mengchen yellow cattle (M)；F1 of Qincauan cattle×M；F1 of Simmental×M；Yubei yellow cattle(Y)；F2 of Y×Charoleis ×Limousin；F2 of Y×Charoleis×Simmental.Then,the four factors regression equation for estimating yellow cattle's liveweight was established. |
| Key words: regression yellow cattle liveweight liveweight estimating |
