Chinanews, Nanning, Oct 16 – After it successfully produced the body cell cloning ox in 2005, Guangxi has made another achievement in its cloning technology. Recently, a body cell cloning pig was born in Guangxi. This is the first cloning pig produced through the body cell technology, said Lu Shengsheng, a professor at the Guangxi Zoological Technology Insitute under Guangxi University, on Monday.

At present, the cloning pig is very healthy. It is also the fifth body cell cloning pig ever produced in China.

In 2004, Guangxi University and Guangxi Animal Husbandry Research Institute jointly¹ conducted a research program on the nuclear transplantation² in Bama mini pigs. Lu Shengsheng, who was responsible for the research program, used the body cell of a Bama mini pig as the donor³ cell and the oocyte of the pig as the recipient⁴ cytoplasm. Through the enucleation, re-injection and activation⁵ process, scientists obtained a cloned embryo⁶ cell. With three years research, scientists injected the embryo into the womb of a local pig type called Luchuan pig. The embryo had been stayed in the pig's womb for about 110 days and at nine o'clock on October 13, a cloned pig was born at the Luchuan Pig Farm at Guangxi Animal Husbandry Research Institute.

Arriving at the scene, this reporter saw that the pig weighed 0.7 kilogram and its body length was about 20 centimeters. The cloned pig was safe and sound and it walked around its mother from time to time wanting to have some milk.

The birth of the first cloning pig in Guangxi has laid a solid foundation for the research of transgenetic pigs, which has a scientific significance in that it can provide a way for scientists to do organ transplatation through animal organs. The first cloning pig might also provide some scientific clues for the protection of the Bama mini pig, a pig that has high economic value in Guangxi. It shows that the body cell cloning technology is quite mature in Guangxi now, said researchers at Guangxi Animal Husbandry Research Institute.
