Abstract:

The first authorized medicine-ATryn produced by transgenic goat mammary gland bioreactor has been authorized into global market in Aug. 2006. This symbolizes that the transgenic technology has entered into a new golden-era in animal husbandry and biomedical industry. This paper summarizes the history of adopting transgenic technology in improving livestock abroad and at home and the current status of transgenic animal research and the progress of commercialization. The development of animal cloning technology has not only boosted the transgenic efficiency, but also provided a new way to knockout livestock gene and to fix targeted integration. The transgenic animal research is accelerating the progress of medicine production, disease model, stem cell therapy, and xenotranso plantation. In the area of livestock transgenic breeding, many breakthroughs have been achieved, especially in the improvementof certain important production traits such as meat quality and growth rate, etc. Additionally, the evaluation for the research on transgenic animal and on the biosafety assessment are perfecting daily. Apparently, the industrialization of transgenic animal just begins to display its brilliant future, which will definitely exert a profound impact on the mankind and social development.
