Jiangkou radish pig is a specialty of Jiangkou County, Tongren City, Guizhou Province. The development of "Jiangkou radish pig" has been going on for hundreds of years. The radish pig skin produced is thin, tender and delicious, and is famous for its shape like radish. It is not long and is called radish pig. Jiangkou radish pig is also called "drill head." This variety is a unique variety formed by the people of Jiangkou County through artificial selection and natural selection during the long-term grazing and feeding process. It has the characteristics of short stature, rough feeding and strong resistance. The radish pork is thin and thin, the meat is tender and the meat is delicious. It is named after the body shape, meat quality or taste. The radish pig is mainly produced in the townships of Taoying Township and Dampan Township in Jiangkou County under the Fanjing Mountain, so it is also called Fanjingshan radish pig.

Jiangkou Luobopig, mainly produced in Jiangkou County in the northeast of Guizhou Province, is rich in body shape and looks like radish after fattening. Therefore, the local people call it “radish pig”. Jiangkou radish pig is a small and medium-sized pig breed formed by the local people for long-term breeding. It has the characteristics of resistance to rough feeding, strong adaptability, early maturity and easy fat, and thin skin and tenderness. However, it has a small body size, a slow growth rate, a low production performance, and a low carcass lean rate. The main producing area of ​​Jiangkou radish pig is located at the easternmost part of the Yunnan-Guizhou Plateau. It is the southern foot of the Fanjing Mountain bordering the eastern part of Guizhou Province and the west of Xiangxi and southern Sichuan. The hills are undulating and are mountainous or semi-mountainous. The altitude is 300-600m and the highest is 1000m. The annual average temperature is 16.4 °C, the highest temperature is 40 °C, the lowest temperature is -4 °C; the frost-free period is about 280 days. The annual precipitation is 1300mm and the relative humidity is 82%. It is one of the areas with low altitude, abundant rainfall, high temperature and high humidity in Guizhou Province. The soil layer is deep and the soil is yellow soil and brown soil. The crops are cooked twice a year, mainly rice, sweet potatoes, corn, potatoes, and rapeseed, as well as wheat, beans, and peanuts. Forage grass is mainly ryegrass, and forage grass is rich in resources. The county has fertile land, lush vegetation, high forest coverage and superior ecological conditions. The local people have a tradition of processing bacon and sausage products. Jiangkou Fanjingshan radish pig is a local fine pig breed formed in the special ecological environment under Fanjing Mountain after thousands of years of natural breeding. Jiangkou Fanjingshan radish pig was named and unique in 1986. Guizhou Livestock and Poultry Variety and "Guizhou Province Livestock and Poultry Breeding Resources Protection List" were included in the "National Livestock and Poultry Resources Management Committee" in 2003. In 2008, the Guizhou Provincial Institute of Animal Husbandry and Veterinary Science and the College of Bioengineering of Guizhou University jointly organized a scientific research team to systematically study the physiological characteristics and physical and chemical indicators of Jiangkou radish pigs, and clarified the “Jiangkou Radish Pig Standard”. The county and provincial and local agriculture and animal husbandry departments began to protect the radish pigs in 2006. At present, the county party committee and the county government have made the development of the radish pig industry an important starting point for the county's “reduction of poverty and hat removal”. The radish pig industry development plan has issued a series of support policies to promote the development of radish pigs. The population of radish pigs in the county has been restored. At the end of 2010, the number of radish pigs in the county was only 15,000 heads. In 2011, it rose to 35,000 heads. In 2012, it will reach 100,000 heads. By 2015, it will reach more than 200,000 heads, reaching the county's per capita acre of walnut trees. Everyone has a radish pig." Jiangkou radish pigs are mainly grazing, roughage is mainly sorghum, and the concentrates are broken rice, corn, sweet potato, potato, etc., Jiangkou radish pig is resistant to rough feeding, and more coarse green material is fed in the early stage of fattening. . Most of the pens are floor slabs or ground circles. The sows are raised in the earth's circle and are mainly fed green feed. They are fed twice a day and grazing every day to allow them to freely move and feed. After the sow is pregnant, add a small amount of corn flour or rice syrup. After a few days after delivery, feed the concentrate such as soy milk or porridge. After the piglets start to feed, the sow concentrate is gradually reduced. Feeding piglets usually start feeding at 20 to 30 days of age, feeding porridge and polenta. Piglets are fed after a single month, mainly corn, fine glutinous rice and porridge. The fattening pigs are fattened by the “hanging shelf” method. After the pumpkin, sweet potato and potato are harvested, the concentrate is fed to the fertilizer until it is released. Jiangkou radish pig is a small and medium-sized pig breed formed by the local people for long-term breeding. It has the characteristics of resistance to rough feeding, strong adaptability, early maturity and easy fat, and thin skin and tenderness. However, it has a small body size, a slow growth rate, a low production performance, and a low carcass lean rate. In the future, we should strengthen the breeding of this variety on the basis of seed conservation, improve the management level of feeding, and gradually improve its production performance. The use of Jiangkou radish pig as the female parent to carry out binary and ternary cross-breeding with imported pig breeds to improve the efficiency of local pig production.
