| 摘 要： | 通过黑龙江省香坊实验农场奶牛场50头初产牛90天、120天估测305天产奶量的回归方程：y＝851．93－1．485X1＋3．115X2，经检验准确度（R）可达88．57％．在生产实践中，利用此方程可以90天和120天的产奶记录，提前选择对奶牛育种工作起重点作用的初产母牛． |
| 关 键 词： | 黑白花奶牛 产奶量 回归方程 预测 选择 |

| Abstract: | Milk crop regression equaton of milch cow fed 305 days was estimated:y = 851.93 - 1.485X1 3.115X2 with 50 primiparal cows fed 90,120 days in Xiangfang experi mental form Heilongiiang province. Accuracy attained 88.57%. In producing practice, it was very important for milch cow breeding to select primiparal cow in advanceusing the eqwtion. |
| Keywords: | spotted milch cow milk crop Regression equation Predetermination selection |
