Located in the subtropical zone, with mild climate, abundant rainfall and high crop yield, it is one of the famous agricultural high and stable yield areas in China. Local people have more land and less land, so pigs can only be raised in captivity, with earth or grass in the circle, commonly known as "warm circle", and pigs do not see the sun all the year round. The concentrate is mainly barley, rice bran and wheat bran, while the green feed is mainly radish, pumpkin, grass and aquatic feed. These feeds have more phosphorus and less calcium, which is not conducive to the development of bones, but is conducive to the development of reproductive organs. The domestic transportation is convenient, the pig breeding communication is frequent, the mobility is large, and various forms of hybridization take place among various local groups, so the genetic basis is extremely rich.

When a boar less than 10 days old is injected with a mixture of sodium chloride and formaldehyde solution, its testicles will begin to swell, and the swelling will decrease after 5 days.
