提高牛人工授精覆盖面的试验研究

Experimental Study to Improve the Coverage of Artificial Insemination in Cattle

为了使远离牛冻配点区域的能繁母牛及时配种,发挥良种牛生产性能,提高养牛经济效益,增加农户收入。通过离冻配点不同路程、不同发情时间及冻精解冻温度进行统计分析。结果,结果表明,对远离冻配点区域的能繁母牛,在发情结束后4~6 h,解冻温度为35~37℃,子宫角深部输精是完全可行的。

In order to make the cattle far away from the area of frozen distribution point of the fertile cows in a timely manner,play the production performance of good breed cattle,improve the economic benefits of cattle,and increase the income of farmers,statistical analysis is carried out by different distance from the frozen matching point,different time of affection and thawing temperature of frost-cream.The results showed that it was feasible for fertile cows far from the frozen distribution point,with a thawing temperature of 35 to 37 degrees for 4 to 6 hours after the end of case.
