Hainan Academy of Agricultural Sciences took Hainan local wild boar, Wuzhishan pig and other pig breeds as resources, and after years of painstaking breeding, it cultivated a new type of wild game pig. "Wild Wujin" is the registered trademark of this pig breed. "Wild Wujin" is a new type of fine pig with stable game quality, which is different from the so-called "special wild boar" or the wild boar domesticated by randomly improving pork quality. It can be said that "wild Wujin"-the game miniature pig has long been ahead of the so-called "special wild boar". This breed of pig has strong resistance, strong adaptability and low feeding cost.
