"Keke", the second cloned cow in China, is in normal condition

Introduction: new page 1, China News Agency, Jinan, January 24 (Han Xianyi) after the death of China's first cloned cattle completely bred with local technology in Shandong Province, the second cloned cattle "Keke" welcomed by the center at 15:30 on the 19th is in normal condition While waiting patiently for the delivery of the other ten cows, Professor Ma Shiyuan of Shandong Academy of Agricultural Sciences, who is in charge of the technology of this project, accepted an interview He believed that the cloning of cattle from the laboratory to the realization of industrial development, at least in five to seven years to achieve three consecutive steps Ma Shiyuan, who undertook the work of cloned embryo transfer in this experiment, thinks that the first step to realize the industrialization of cloned cattle is to solve the problem of further maturity and perfection of cloning research There is a defect in this experiment: the conception rate is lower than the practical level, and the abortion rate is higher than the normal level Although the conception rate of 20% is higher than that of some foreign research institutions, it can not meet the practical requirements of industrialization The abortion rate of 52% is much higher than that of 10-15% of normal breeding methods This means that we can neither mass produce embryos nor minimize the cost The second step is "engineering transformation of cloned embryo technology" There is a big gap between the laboratory and the actual large-scale chemical plant production An embryo factory needs to have a fixed process flow, and there is a connection between the front and the back There is a strict proportion between raw materials, intermediate products and final products in terms of quantity The most important thing is that the large-scale production pursues the lowest cost and the maximum output value This requirement is far beyond the current level of embryo cloning technology Professor Ma estimates that it will take at least one year to reach this level The third step is that cloned embryos must be recognized by consumers to win the market Professor Ma believes that this is an economic issue rather than a technical one As long as the first and second steps are up, it will be easy for the third step to be up Because the cloned calves are all high-yield cows, and their prices and costs are not very high, why not consumers? Professor Ma, who is optimistic about the industrialization of cloning technology, estimates that it will take five to seven years from the current level of cloning technology to the final realization of industrialization At that time, there will be immeasurable changes in China's dairy industry
