	Applications of Embryo Transfer Technology 1. This technology achieves a surprisingly rapid rate of multiplication of animals of the selected superior genotype. In natural course, a single female will produce a single progeny in about one year. But using superovulation and embryo transfer technology, it is feasible to collect around 36 embryos from one female in one year. Assuming an average success rate of 50% in the embryo transfer, an average of 18 progeny can be derived from one superior female in one year.
2. Each young embryo can be split into 2-4 parts, each of which would develop into a separate progeny; this is called embryo splitting. By combining embryo splitting with superovulation, the rate of multiplication can be further increased. 3. The young embryos can be frozen and stored in liquid nitrogen (at -196°C; cryopreservation) for up to 10 years or more and used at a subsequent date. The frozen embryos are far more easier to transport, and present negligible quarantine problems as compared to the animals themselves. 4. Superior cows that are unfit to carry the foetus for full term, can serve as donors of the young embryos.
