Problems solved by technology

Only a few of the introduced new varieties are bred and purified in enterprises and scientific research units, while most of them flow directly into the market, and the quality and hybridization effect of the varieties cannot be monitored

Due to my country's vast territory, great climate differences, different ecological conditions, and different natural resources, at present, there is no hybridization utilization system suitable for different regional characteristics, and the lack of a unified planning breeding system has led to the fact that most of the mutton in my country is some local breeds and hybrids.
