The cost of abortion is less than 100 yuan, and the mortality rate is very high. Can cloned cattle get up

Introduction: with the birth of domestic cloned cattle in China, there are many doubts about cloned cattle For this reason, our reporter interviewed researcher Ma Shiyuan, technical director of the project, and asked him to give a more authoritative explanation Advantage: the cost of embryo is less than 100 yuan Professor Ma Shiyuan strongly opposes that some experts and media think there is no market for cloned cattle at present "The market prospect of cloned cattle is very considerable Only in terms of the situation we are facing, at present, the cost of an embryo of a general improved cattle is 800-1000 yuan, and the market price is as high as 2000 yuan Many agricultural units want to buy it but can't afford it In order to introduce improved varieties, we have purchased 800 pieces and paid 1.6 million yuan And the cost of cloning cattle embryo is less than 100 yuan! All of them are of excellent absolute performance How can we say that there is no market prospect for such a huge gap? " Lower costs and better varieties will eventually lead to better beef and milk for less Difficult problem: the abortion rate and mortality rate are high, Professor Ma said, there are still "two high and one low" problems in the project, namely, low pregnancy rate, high abortion rate and high post birth mortality rate In addition, if cloned cattle are really going on the road of industrialization in the future, there are still two problems: first, if we want to reduce the cost, we must expand the scale and take the road of systematic engineering; second, in the period of solving the problem, we should always pay attention to the market demand and develop cloned embryos that adapt to the market After the death of Weiwei, Professor Ma dissected himself and found that the heart, lung, liver and kidney were deformed "It's not only valuable to live, but also valuable to die Previous studies have shown that the respiratory and digestive systems of cloned cattle are prone to malfunction If this problem can be solved in the future, the contribution of dead cloned cattle will be the greatest." In fact, the research project of cloned cattle has been determined since 1998, but several experiments have not been successful What is lacking is a large-scale cattle raising enterprise that is willing to support After cooperating with Caoxian Guiyi group, the enterprise has provided a large number of acceptor cows Scientific research institutions are responsible for technology, and enterprises provide material support Only by combining efforts can we achieve this step " "The technological research and industrial production of the laboratory are actually mutually promoting and virtuous New technology research provides a new direction for production, but also produces huge economic benefits; industrial production provides more samples for technology research If there are no more cloned cattle to do experiments, how can we understand many potential problems of cloning technology?
