【摘要】 近年来，奶牛胚胎移植在国内发展迅速，体外胚生产作为奶牛胚胎移植发展的方向和趋势，在品种改良和遗传育种中具有广泛的应用前景，已成为奶牛繁育的重要手段。但由于卵母细胞体外发育的环境与体内差异巨大，如何提高卵母细胞和胚胎的发育效率是当下亟待解决的问题。随着体外成熟体系和胚胎成像系统快速发展，对卵母细胞和胚胎的体外发育的机理有了更深入的认识，也为优化体外胚生产体系提供了新的思路。本文就国内外奶牛体外胚生产的最新进展以及对包括体外成熟技术、胚胎成像技术等相关技术进行阐述，以期为更好地推广和应用体外胚生产提供理论参考和依据。更多还原

【Abstract】 With the rapid development of in vitro embryo production technology, IVEP has become an important technological tool in the production of bovine breeding. Since the significant advantage in the fields of accelerating genetic progress and improving breeding efficiency, the understanding of development of oocytes and embryos in vitro is particularly important. To improve the efficiency of IVEP, a great deal of studies have been done on bovine embryo culture in vitro. Herein, this review focused on the advances in IVM and embryo imaging, such as in vitro acquisition and maturation of oocytes, and time-lapse imaging of oocytes and embryos.更多还原
