The African swine fever epidemic in China caused a significant decrease in the pig population and revealed weaknesses in breeding and processing. Chinese pig scientists have been working on developing their own resistant and efficient breed, with the Rongchang pig breed being recognized and included in breeding standards and conservation lists. The Rongchang Index, known as the "weathervane of Rongchang," has been established as a key market index for monitoring and analyzing the domestic pig wholesale market, and efforts are underway to create a digital pork market platform based on this index.
