The map below shows the 5 major swine breeding regions in China. The red area, Northeast China, occupies about 10 percent of pig production in China; the yellow area, North China, occupies about 26 percent of pig production; the blue area, the Yangtze River Region, occupies about 25 percent of pig production; the green area, South China, occupies 13 percent of production; and the purple area, Southwest China, occupies the remaining 21 percent. Swine from these five major regions constitute 95 percent of total pig production in China.
Current trends indicate that swine production is shifting north and west. Despite its mountainous terrain, the Southwest Region has seen high growth due to the large amount of pork consumption in the region. While South China also consumes a high volume of pork, this area has seen a decrease in swine production as a result of strict environmental regulations which have increased production costs. Production costs are lowest in the Northeast Region as result of its co-location with feed production centers.
