What is the biggest difference between cows and buffaloes?

A few days ago, in an interview with Guangxi Buffalo Research Institute, it was learned that scientists in China are using the most advanced biotechnology in the world to start in-vitro propagation of buffaloes in batches. Using in vitro propagation technology, it used to take nearly 10 years to cultivate a fairly pure milk buffalo, and now it can produce the pure milk buffalo of that year. According to Yang Bingzhuang, chairman of the Asian Buffalo Association and director of Guangxi Buffalo Research Institute, for thousands of years, China's traditional buffalo has only been used for cultivated land, while Indian Mola Buffalo and Pakistani Niri-Lafite Buffalo are the best milk buffalo in the world. More than 40 years ago, China introduced 50 excellent breeds of buffalo from Indian and Pakistani countries. The introduction and breeding of milk buffalo is a worldwide problem, and its estrus season is not obvious, the conception rate is low and the breeding cycle is long. Scientists have bred local buffaloes by traditional artificial insemination and obtained a new generation of breeding cattle. However, it takes a long time to obtain high-pedigree breeding cattle by relying on this variety improvement method, so the population cannot be propagated and expanded rapidly. Since 2000, Guangxi Buffalo Research Institute has used the oocytes of milk buffalo to culture and mature in vitro, and then fertilized in vitro to become blastocysts, and then transplanted them into local female buffaloes to "get pregnant by abdomen". In the past three years, 39 female buffaloes were transferred to embryos, of which 26 were pregnant, and the pregnancy rate was 66.7%. At present, 24 test-tube buffaloes have been successfully born and grow normally. These test-tube buffaloes are the largest test-tube buffalo herds in the world at present. China plans to improve more than 20 million buffaloes in China into milk buffalo on a large scale. The application of buffalo in vitro propagation technology will greatly accelerate the pace of buffalo variety improvement in China.
