Sows, or adult females bred to produce piglets for slaughter, account for roughly one in 10 pigs in China. Up to 50% of China's breeding pigs may have been killed as a result of the country's African swine fever epidemic. The disease has spread from South Africa and is now affecting more than 30 million pigs.
