China's cloned cattle will be born soon

Introduction: will cloning affect species diversity? Professor Ma Shiyuan of Shandong University of animal embryo engineering center is about to give birth to the cloned cattle The reporter interviewed Professor Ma on this issue Professor Ma said that as long as we establish a complete gene pool of species, it will not affect the diversity of species One of the prototypes of the cloned cattle in Caoxian is No 663 Chinese Holstein high-yield cow from Beijing Xiaowangzhuang dairy farm, and the other is a 1.25-ton No 018 gepwei bull from Shandong large and medium animal embryo engineering center Cloning only one cow is not conducive to the protection of animal diversity In the future, different high-yield cattle should be cloned as much as possible In fact, every individual in the animal population has some genes that are conducive to the survival and development of the animal For example, although the yield of high-yield cattle is higher than that of local cattle, the disease resistance of local cattle is stronger than that of high-yield cattle Therefore, it is necessary to establish gene bank to preserve these genes as completely as possible There must be different species to establish gene pool, different varieties for the same species and different conservation forms for the same variety The different preservation forms of the same breed include semen, egg, embryo, somatic cell, etc A complete gene bank of domestic animals should keep at least 100 kinds of "preservation materials" According to Professor Ma, now the Ministry of agriculture has established a gene bank in China In addition to the government, there is a broad prospect for enterprises to establish gene pool For example, the gene bank established by the enterprise can commercialize livestock genes, make and sell embryos according to the market demand, and the profits obtained can continue to build a gene bank with richer germplasm resources, and can guarantee the qualification rate of materials stored in the gene bank through market inspection, thus forming a virtuous cycle (author:) share to feed Weibo share to:
