Sperm classification technology promotes dairy cows in China

The XY Breeding (Tianjin) Co., Ltd., a joint venture between China Seed Import & Export Co., Ltd., Xinjiang Jinniu Bio Inc. and the United States Yada Exports Co., Ltd., is a sperm cell sorter and technology introduced from the United States XY Corporation, utilizing high-yielding dairy cattle bulls. Sexual control of semen, the cow's birth rate reached more than 90%. The establishment of this company and the introduction of this technology will play an active role in accelerating the development of China's dairy industry and increasing farmers' income. XY sperm sorting technology is currently the world's most advanced breeder breeding technology in the field of biology. The insemination survival rate of XY sperm has reached 65%, and the separation success rate of XY sperm has reached 93%, which means that with the segregated X semen, the birth rate of cows will also reach more than 90%. Using a traditional cryogenic technique to obtain a good breed of cow calf requires 5 doses of semen for two years, while the use of XY sperm separation technology requires only 2.5 doses of semen for a year. Therefore, regardless of the cost of breeding or the efficiency considerations, XY sperm separation technology will be a revolution in animal husbandry. The implementation of the project will have a tremendous effect on the rapid increase in the number of cows in China and meet the needs of the vast number of farmers, and will have great social and economic benefits. Relevant experts believe that the technology has the following two advantages: First, it is in line with the national industrial development strategy. With the continuous improvement of the people’s living standards, the consumption of dairy products by urban and rural residents, especially large and medium-sized urban residents, has been increasing year by year. The rapid growth of the dairy product market has led to the rapid development of dairy cattle breeding. However, due to the low natural reproduction rate of cows and the slow propagation rate, the current domestic cow population expansion has been greatly restricted. The introduction of large numbers of cows from foreign countries not only requires a large amount of foreign exchange, but is also limited by the insufficient number of isolation sites and restrictions on the source of imported cattle. . Therefore, the lack of high-yielding purebred dairy cows has become the bottleneck restricting the development of China's dairy industry. The second is to promote the industrialization of dairy cattle breeding. The dairy industry in China is developing rapidly, but the production level is low. The annual milk production capacity of domestic dairy cows is about 3,000 kg, which is much lower than the world advanced level. One of the important reasons is that the breeding technology of elite dairy cows is backward, the breeding cycle is long, and the rate of improved seeds is low. Severely hindered the development of the dairy industry. The XY project not only has advanced breeding technology, but also greatly shortens the breeding cycle, and is expected to meet the demand of the domestic market for good-quality dairy cows.
