Approaching cloned cattle

Introduction: Jinan cattle is a unique local yellow cattle breed in China, with cold resistance, disease resistance and good meat quality At the end of 1970s, there were more than 10000 cattle in China At present, the pure breed of Southern Hebei cattle is on the verge of extinction On April 27 this year, China successfully cloned the first local high-quality South Hebei yellow cattle, which is of great practical value for the protection of endangered excellent livestock breeds The scientist in charge of the cloning experiment gave the newborn calf a rather romantic name - pova After more than 40 days of careful care, Beauvoir's growth and development are in good condition Earlier this year, the Institute of zoology of the Chinese Academy of Sciences also successfully cloned high-yield Holstein cows According to scientists, if these calves are bred naturally or by using cloning technology to give birth to calves, it is possible to give birth to cloned milk The important progress made by Chinese scientists in the research of somatic cell cloning will lay a solid foundation for the future cloning of livestock, the transformation of China's dairy cattle and the industrialization of beef cattle culture So, how long will it take for these cloned cattle to go out of the laboratory and finally realize industrial production? According to scientists' expectation, in ten years, people will be able to eat the beef of high-quality cloned cattle and drink the milk produced by cloned cows This is what the traditional hybrid technology can't do In China, animal somatic cell cloning has been studied since 1997 Only two years later, transgenic somatic cell cloned goat has been successfully cloned In 2001 and 2002, many times through the somatic cell cloning technology, successfully cloned the introduced good breed cattle and the local breed cattle in China China has made great progress in the field of cloned cattle technology, which marks that China has been in the forefront of the world in the field of cloned cattle technology BTS
