牛品种改良胚胎移植技术

Improved embryo transfer technique of cattle breeds

牛品种改良过程中,胚胎移植手术是近年应用较为先进的一类繁殖技术,它是继人工授精技术后的另一次技术革新。胚胎移植是指将宫体早期胚胎从其体内取出后,或体外培养生产胚胎移植到另1头同种且与胚胎发育阶段相符合的受体子宫中,使这个受体能完成整个生长发育过程,相对于人工授精技术,胚胎移植技术具有操作技术要求高、精确度高的特点。该文主要论述牛品种改良过程中胚胎移植技术要点。

In the process of cattle breed improvement,embryo transfer is an advanced reproductive technique,which is another technical innovation after artificial insemination.Embryo Transfer is the transfer of an early embryo from the uterine body into another recipient uterus of the same species,so that the recipient can complete the whole process of growth and development,compared with artificial insemination,embryo transfer has the characteristics of high operation and precision.This paper mainly discusses the main points of embryo transfer technology in the process of cattle breed improvement.
