摘要： 在进行牛胚胎移植时，为了使移植工作能够集中进行，需要对大批受体牛进行同期发情处理。试验比较了不同处理方法、不同繁殖状况、不同营养水平、不同带犊情况等因素对受体牛同期发情效果的影响。结果显示：两种处理方法之间差异不显著(p>0.05)；不同繁育情况之间差异各异；典型放牧条件下不同营养水平产犊超过 3 个月同期发情率都显著高于产犊不足 3 个月的牛。

Abstract: It is necessary to treat a large numbers of synchronization of oestrus to recipients before the cow embryo transplantation. This study investigated the effects of synchronization of oestrus from two different ways, parity (heifers, weaned cows and lactating cows), different nutrition levels. The result showed that two methods did not significantly affect the results of synchronization of oestrus (P> 0.05).There were kinds of results about parity effect to synchronization of oestrus. The trial investigated the optimal time of recipient cattle with calves is least 3 months under different nutrition levels of nature grazing conditions.
