摘要
马属动物属季节性单胎动物,从母马或母驴出现发情表现到排卵,持续3~13 d不等,该生理特征极大地影响其繁殖效率。hCG作为LH类似物不会受性激素反馈调节机制的制约,广泛应用于马属动物卵泡发育和排卵。从性激素在哺乳动物卵泡发育过程中的作用、马属动物主卵泡波与LH诱导的优势卵泡排卵、外源性激素对马属动物卵泡发育的影响、hCG的结构与功能、hCG在延长母马黄体期的应用和hCG在马属动物超数排卵中的应用6个方面内容阐述hCG促进马属动物排卵的研究进展。
Equus are seasonal single-born animals.The duration from the estrous appearance to ovulation lasts for 3 to 13 days in mares or jennets.This physiological characteristic greatly affects their reproductive rate.hCG,as a LH analogue,is widely used in the study of follicular development and ovulation in Equus animals,which is not regulated by sex hormones feedback mechanism.This paper reviews the research progress on ovulation promoted by hCG in Equus animals from the following five aspects:the role of sex hormones in mammalian follicular development,main follicular wave and the ovulation of the dominant follicle induced by LH in Equus animals,the impacts of exogenous hormone on follicular development in Equus animals,structure and function of hCG,the application of hCG in prolonging the luteal phase in mares and in superovulation in Equus animals.
