First boer goat with somatic cell cloning tech born

Chinanews, Beijing, Apr. 10 �C 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.
