Abstract:

The article summarized the transgenic animal technology used in transgenic cattle research, such as microinjection, somatic cell nuclear transfer, virus and the more prospects technology such as ZFN, TALEN and iPS. Reviewed the progress of transgenic cattle research in Domestic and foreign, and the application of transgenic cattle research in mammary bioreactor, breeding for disease resistance and breeding improvement. Finally, transgenic cattle breeding problems and future development trends were discussed to improve the research of transgenic cattle.
