Beijing cattle successfully cloned by China Agricultural University

Introduction: China Agricultural University successfully cloned Beijing cattle The cost of cloning is only 100 yuan On December 11, the State Key Laboratory of agricultural biotechnology of China Agricultural University announced that it successfully cloned two Beijing local cattle Surprisingly, it costs only 100 yuan to clone every local cattle in Beijing! According to Li Ning, Professor of the State Key Laboratory of agricultural biotechnology, China Agricultural University, who is in charge of the project, the difference between the successful cloning of local cattle in Beijing lies in its low cost It only costs 100 yuan to clone each cow, so large-scale cloning of cattle can become a reality "Because we use cloning technology, we save the cost of sexual reproduction Specifically, we do not need the semen of the donor cattle, only the somatic cells of the donor cattle Each donor can save us 30 yuan in cost The egg cells of cattle in the slaughterhouse are of no value to the slaughterhouse, so the slaughterhouse can provide us with the egg cells free of charge In this way, we can clone cattle for only 100 yuan each! "The biggest difference of the cloned cattle is that the oocytes, donor cells and fusion oocytes are all frozen, which is the first time in all the reported cloning cases at home and abroad According to Professor Li, the main contribution to the success of such technology is that it is convenient for transportation and preservation "For example, the cattle farm in Shanghai wants to clone a large number of cattle here We have the technology of freezing all cells, as long as the donor cells are frozen and transported to Beijing! "Professor Li explained Cryopreservation technology has made it possible to clone in different places, and the cost has indeed been reduced to the lowest level because it requires somatic cells rather than semen One of the two cloned cows was named "Shunhua" and the other was not named Three clones were planned and two were successfully produced, with a success rate of about 67% - prospect because cloning technology can control gender, the most direct benefit of cloning cattle is that it can clone large numbers of high-yield female cows or male beef cattle to meet the needs of people to drink milk or eat beef Of course, a large number of other distinctive animals can be cloned to serve daily life For example, at present, Japanese pet pigs are popular with many fashionable women Scientists can clone a large number of pet pigs to meet the market demand This is the biggest benefit of cloning technology marketization -- however, according to Professor Li, there is still a problem to be solved at present, that is, most cloned cattle are born with a broken stomach, which is also one of the problems facing the international cloning community Almost all cloned cattle in the United States were born on a broken stomach Because of the involvement of veterinarians, it increases the cost of producing cloned cattle At present, scientists from the State Key Laboratory of agricultural biotechnology, China Agricultural University are stepping up their research on the relationship between cloning and breaking abdomen (author:) share to feed Weibo share to:
