The excellent local pig breeds in Yunnan Province include Southern Yunnan Small Ear Pig and Wujin Pig (i.e. Dahe Pig and Saba Pig). ), Baoshan pig and Diqing Tibetan pig, and imported improved pigs include Sichuan Neijiang pig and Rongchang pig. Fattening with these purebred piglets has strong adaptability, rough feeding resistance and good meat taste, but it grows slowly, is small in size, has low slaughter rate and poor economic benefits. Fattening with new domestic breeds of pigs such as Xinhuai Pig, Xinjin Pig, Shanghai White Pig and Beijing Black Pig, or with purebred pigs imported from abroad such as Landrace Pig, Baxia Pig, Milov Pig, Subai Pig, Duroc Pig and Hampson Pig, has the advantages of large size, fast growth and high meat yield. However, it is necessary to feed more concentrated feed, and the feeding management conditions are high. At present, in rural areas, pigs should be fattened.
