Scheme For Dairy Cow's Embryo Transfer And Its Related Techniques Application And Expanding

In order to make available plan for expanding embryo transfer and its related techniques to application in dairy cow reproduction, it has been done to collect and analyze researching and applying work for embryo transfer in cow published in china and aboard, and summarized in person-experience regarding with participating projects on researching and expanding the techniques of cow's embryo transfer. It further confirm that the actual value of embryo transfer techniques for dairy cow breeding and improvement in our country, especially significances and roles in aspects of shorting generation, enhancing the stock improvement, enlarging the perform-well stock, raising reproduction rate. Considering the actual situations and existed problems about dairy cow reproduction and embryo transfer techniques expanding in our country, it is proposed that may apply basic and advanced breeding and improvement techniques which include synchronized estrus, superovulation, artificial insemination, recovery of embryo, assessment the quality and sexing the embryo, preservation of embryo, splitting embryo etc. According to different given aims, the plan include more practicable schemes of high speed enlarging existed cow breeding, importing high performance embryos, setting up the given high producible stock, preservation of value resources, raising the production and lowing the cost. This paper figure out a key points and crucial steps while expanding embryo transfer and its related techniques plan be actually practiced in cow reproduction at different conditions.
