Embryonic Biotechnology Accelerates the Development of Dairy Cow Industry in China
With the increasing living standards of the people and the adjustment of the dietary structure, people's demand for fresh milk is getting higher and higher. Recently, the reporter learned from the Biotechnology Institute of the Henan Academy of Agricultural Sciences that the joint agricultural science and technology institute and the Henan Agricultural University jointly sponsored the application of embryonic biotechnology to rapidly expand the quality of dairy cows and conduct large-scale and healthy aquaculture demonstrations. Over the years, researchers have used embryonic biotechnology to achieve a series of advances in the rapid expansion of improved dairy cows and large-scale healthy breeding. According to the person in charge of the project, the application of embryonic biotechnology is the best way and means to rapidly expand the breeds of dairy cows. This new technology can better tap the reproductive potential of elite breeding stocks and carry out long-term preservation of genetic material. It mainly includes embryos. Transplantation technology, embryo sex identification, and in vitro factory production of embryos. Under natural conditions, cows can only produce 3 to 4 females, and the use of embryonic biotechnology can overcome the limitations of the reproductive cycle and reproductive efficiency of animals under natural conditions. The speed of their reproductive offspring is more than ten or even dozens of times under natural conditions. Times, thus rapidly increasing the number of thoroughbred dairy cows. In view of the problems in the process of industrialization of dairy cows in China, such as the low quality of dairy cows and the low yield per unit, the rapid propagation of embryos using the embryo transplant technology is about to pass the US's high-yielding dairy cow's genetics into China through embryonic forms and apply embryo transfer technology. On the basis of the high-yielding dairy cow core group, embryonic biotechnology such as embryo transfer, cryopreservation, and sex identification techniques that have been mastered is used to rapidly expand the number of high-yield dairy cows that exceed 10,000 kilograms. This will greatly reduce the gap between China and the livestock industry in the breeding of dairy cattle, through the application of high technology, resulting in high efficiency, so that China's dairy industry's industrialization process toward high efficiency, scale, intensive development.
