牛发情周期内排卵卵泡的数量和质量与其繁殖性能直接相关。本文就牛发情周期内有关卵泡发育的概念提出、理论建立、研究技术进展进行综述,并对研究前景进行展望。可以确定,随着新技术、新方法的应用,对牛卵泡生长和闭锁机理的进一步研究将会极大改善牛的繁殖性能。
The number and the quality of follicles ovulated in estrous cycle is directly related to bovine reproductive performance. The definition, corresponding theories and technological progress, as welt as the research prospect of follicular development were reviewed in present paper. It's convincing that revealing of the mechanisms underlying bovine follicular development and atresia will greatly improve bovine reproductive performance.
