Jinhua "two-headed black" pig, also known as Jinhua pig, is one of the four famous pigs in China. The formation of Jinhua pigs has a long history. According to the cultural relics of the Western Jin Dynasty (265-316 AD) unearthed in Jinhua County, there are pottery pigs and pottery pig pens: as early as more than 1,600 years ago, the pig raising industry in Jinhua and Quzhou (originally Jinhua area) was already quite large. Due to the rolling hills and inconvenient transportation in the production area, it is very difficult to sell it far away, forcing farmers to find new ways to process cured pork and pork legs for storage and export to other places. According to research, pickling pork legs in Jinhua rural areas began in the Kaiyuan period of the Tang Dynasty (713-742 AD) and has a history of more than 1,200 years. It is said that during the Song Dynasty, Zong Zegong, a native of Yiwu, brought a lot of cured meat from his hometown to entertain his friends when he was marching. It was delicious and high-quality, so he named it "Hometown Meat". It has a history of about 900 years. In addition, Jinhua ham, which is made from Jinhua two black pigs, is one of the three famous ham brands in the world. In 2008, "Jinhua Ham Curing Technique" was listed as a national intangible cultural heritage. In 2014, the "Jinhua City Jinhua Ham" certification trademark was recognized as a well-known trademark in China.

Because the hair on the head, neck, buttocks and tail is black, and the rest is white, it is also called "two-headed black" and is one of the best local breed pigs in the country. It is native to Huashui and Huxi in Dongyang, Yiting in Yiwu, Xiaoshun, Lipu, Caozhai and other places in Jinhua. Since the 1960s, the breeding scope has gradually expanded to include both inside and outside the province. Jinhua pig has thin skin and fine bones, delicious meat and high fat content between the meat. Its hind legs are the best raw material for cured ham. Jinhua pigs have many litters, good mothering performance, large milk production, high feeding rate and good reproductive performance. Relevant departments began to adopt Jinhua pig breeding measures in the late 1970s. The Jinhua Pig Farm, the Municipal Agricultural Science Institute and the Agricultural Experiment Station, and the Dongyang Breed Farm carried out planned breeding work according to three types: large, medium and small.
