Shanghai Succeeds in Pig Embryo Storage in Ultra-low Temperature

This April, technicians at the Livestock Institution of the Shanghai Academy of Agricultural Sciences conducted the transplantation of the embryo of small-sized Bama pigs of Guangxi Zhuang Autonomous Region by using a proper formula of refrigerants. One of the sows became pregnant and gave birth to ten piggies, 8 of which are alive and growing well. Presently, technicians are keeping a close watch of the upgrowth of these piggies.

The success of this experiment marks the first case of pig embryo storage in ultra-low temperature (-196℃) in China, laying a technical foundation for an effective storage of fine local pig varieties and the establishment of a special pig embryo bank. In the future, effort will be made to improve each of the links of the experiment and raise the conception rate so that this technology can be used in production
