| 摘 要： | 我国东北地区地域辽阔,饲草资源丰富,是发展奶牛、肉牛的主要产业带,但是东北地区冬天较冷,对奶牛养殖有一定影响,在繁殖方面会影响奶牛的发情率和受胎率,雌性激素对奶牛的发情和配种妊娠有一定效果。为了提高奶牛的发情率和怀孕率,本试验于10～12月份在阜新地区,随机选择了一些青年牛分为对照组、促排卵素组和促黄体素组,探讨提高受胎率的方法,结果显示受胎率并没有显著提高(P>0.05),下一步应该从其他方法再做努力。

However, the Northeast area main industrial zone, which is a cast territory and is cold and has a certain influence on dairy farming, especially estrus rate and pregnant rate of cows.
