| 摘 要： | 利用多元回归原理，对甘肃省家畜繁育中心种牛场22头西门塔尔种子母牛最高日产量（x1）、90d泌乳量（x2）与初产３０５d泌乳量（y）的关系进行研究，得出回归方程：y=303.23 32.73x1 2.167x2，显著性检验结果，Ｐ＜０.01，差异极显著。

| Abstract: | Based on multiple regression principle, the highest daily milk yield, 90-day milk yield and 305-day milkyield of 22 Simmental cows in Gansu Domestic Animal Animal Reproduction and Breeding Center were analyzed,the results indicated that 305-day milk yield has a significant regressive relationship with the highest daily milk yield and 90-day milk yield(P<0.01). |
