| 摘 要： | 本试验利用DRS超声动物妊娠检查仪对286头奶牛进行了早期妊娠探测。总的探测准确率为93.1%。其中最早检出时间在配后15～16天。探测准确率为91.3%。配后17～21天的探测准确率为92.3％,配后31～60天的探测准确率为95.0%,未孕空怀牛的探测准确率为100％。我们认为这一方法操作简便,且能更早地作出诊断,探测准确率较高,可满足生产上的需要。

| Abstract: | In this experiment we used the D R S ultrasonic gestation detector
to esamine the gestation rate for 286 cows in the earlier gestation period,
the average exact rate is 93.1 percent. The earliest time of the exact
examination among them is 15 days to 16 days after breeding, the exact
rate is 91.3 percent. The rates of 17 days to 21 days, and 31 days to 60
days after breeding are 92 percent and 95 percent respectively. By this
method the exact rate of the reaches 100 percent.
We consider this method is easy to operate indicates earlier diagnosis
and will satisfy the needs of production. |
