Qitai Uses Embryo Transfer Technology to Breed New Red Deer Varieties
Applying embryo transfer technology to the breeding of Tianshan red deer will cause a sensation in China's wildlife conservation community. On December 18, 2003, **Ma Mingkui, director of the Qitai Forest Farm, pointed to the red deer at the red deer breeding farm and told reporters: "No. 366, No. 66, and No. 399, these 3 red deer are all pregnant." This work began in September 2003, and a total of 13 red deer underwent embryo transfer. They are all red deer from the Qitai Forest Farm red deer breeding farm. This farm is also China's only Tianshan red deer germplasm protection and breeding base. Tarim

Methods of Queen Rearing by Larva Transfer and Key Management Points
(1) Tools for queen rearing by larva transfer The tools used for queen rearing by larva transfer include a larva transfer needle, a queen rearing frame, a wax bowl stick and wax bowls, a towel, a washbasin, royal jelly, etc. The larva transfer needle is a tool used to transfer young larvae into queen cell cups. It can be made from thick copper wire or a goose feather quill, with one end shaped into a flat, thin tongue and the other into a curved spoon shape. A larva transfer needle with a spring is convenient to use. The queen rearing frame is a frame for holding queen cells. It can be modified from a standard frame, with the top and bottom bars and side panels of equal width, about 13 mm. Inside the frame, 3 slats 10 mm wide are installed horizontally at equal distances. The wax bowl stick is dipped

Chinese-American biologist successfully breeds double-gene transfer cloned pig
The University of Connecticut in the United States announced recently that renowned Chinese-American biologist Yang Xiangzhong, in cooperation with the scientific research department of Taiwan, China, has bred the world's first double-gene transfer cloned pig carrying human coagulation factor IX and porcine lactoferrin. This research achievement is expected to be used to treat hemophilia. According to Yang Xiangzhong, a professor at the University of Connecticut, this research was conducted under extreme secrecy by his research team in cooperation with the Taiwan Animal Technology Research Institute. The first cloned pig was born on February 15 this year at the Taiwan Animal Research Institute
