Chinanews, Beijing, Apr. 10 – China's first boer goat born with somatic cell cloning technology, the second boer goat born with such technology in the world, was produced at the Tianjin Pasturage and Veterinarian Research Institute at 12:40 on Monday, the Beijing News reported.On Monday afternoon, this reporter saw the little goat at the lab base in the Tianjin Pasturage and Veterinarian Research Institute. The new-born goat was white in color and had a brown head, a typical feature of the boer goat. The parent goat had white hair all over its body. The baby cloned goat is named “Jin Ying,” which means the "hero in Tianjin".The somatic cell cloning boer goat project was led by Liu Ling, a Chinese American cloning expert. The project was kicked off in 2000. In 2003, scientists injected the ear skin cells taken from an Australian boer goat ( the goat died in 2003) into the egg cell of an ordinary goat after scientists took out its cell nucleus. Scientists then transplanted the cloned embryo into the body of a receptor goat. Through hundreds of experiments, scientists finally managed to transplant the cloned embryo into the body of an ordinary female goat. After 155 days of pregnancy, the female goat produced a 5.5-kilogram female baby goat, which carried the same genetic information as the original boer goat.Since Jin Ying was large physically, scientists had worried that it might die before it was born, or might have some sequelae after it was born. So scientists had intended to give a Caesarean operation to the mother goat. In the end, the baby cloned goat was delivered smoothly in one hour on Monday morning.
