生殖激素调控卵泡发育影响母牛繁殖性能的研究

doi:10.12377/1671-4393.24.09.05

摘要/Abstract

摘要： 卵泡发育是保证母牛繁殖性能的基本前提。控制卵泡发育包括新卵泡波定时出现、优势卵泡选择和生长、高质量卵母细胞定时排卵。卵泡发育所有生理过程发生在动态激素环境下,主要由腺体分泌促性腺激素驱动。从该意义上说,控制卵泡发育本质是需精确操纵激素环境来调控促性腺激素分泌。本文讨论定时人工输精（TAI）方案背后的生理基础,为母牛繁殖效率提升提供参考。

Abstract: The development of follicles is the basic premise to ensure the reproductive performance of cows. Follicular development Controlling comprises the synchronized emergence of a new follicular wave,selection and growth of the dominant follicle,and synchronized ovulation of a high-quality oocyte .All these follicular events,primarily driven by gonadotropin secretion,occur under a very dynamic hormonal environment. In this sense, follicular development controlling demands essentially a precise manipulation of the hormonal environment to modulate gonadotropin secretion. This paper discussed the physiological basis behind the timed-artificial insemination（TAI）scheme,hoping to provide reference and help to improve the reproductive efficiency of cows.

Key words: follicle development, timed-artificial insemination（TAI）, dominant follicle, hormone, cow
