Wujin pig is a herbivorous pig in Yunnan-Guizhou Plateau. Up to now, the feeding mode of "grazing+supplementary feeding+captivity" is still adopted, that is, piglets are grazing in the wild and supplemented in the morning and evening. The unique breeding method makes Wujin pig known as "Chinese herbal medicine to eat, mineral water to drink, and long bodybuilding meat". Therefore, the quality of fresh meat, ham, bacon and other products is very good, and the world-famous Yunnan Xuanwei ham is made of Wujin pig, so it is called "Xuanwei Ham Wujin Pig". The breeding of Wujin pigs in mountainous and semi-mountainous areas can be combined with stocking and captivity, and it will be completely converted to house feeding when the mountains are closed in winter. In Wujin pigsty, pigs can be fed with green feed. According to the characteristics of large feed intake, low cellulose content, rich in carbohydrates and protein, the best feed crop for pigs in agricultural areas is hn-mc grain amaranth, followed by hn-mc Viburnum, hn-mc Russian feed vegetables and hn-mc chicory. In order to solve the problem of insufficient green feed in winter and spring, hn-mc Mexican corn and hn-mc sweet sorghum should be planted for feeding. It is necessary to raise sows and boars, and to plant hn-mc and hn-mc chicory. Mixed feed of Wujin pig essence, green, coarse and auxiliary: Sows can use bran, dregs and auxiliary materials, especially green feed. It is necessary to ensure continuous rotation throughout the year and feed more green feed, which can not only save food, but also improve the conception rate and litter size. During pregnancy, auxiliary feed and green feed are the main ingredients, and the ingredients should be properly matched. During lactation, ingredients are the main ingredients, and green feed and green feed are mostly matched. Pigpen is a prerequisite for raising pigs in Wujin. Farmers should build a sanitary fence according to local conditions, and farmers with conditions should build a "trinity" sanitary fence, which is dry, ventilated, heat-insulating and light-transmitting, and is equipped with a sink, a pool and a pig bed, which is convenient for management and epidemic prevention, so as to accumulate fertilizer outside the fence. According to male, female and growing-finishing pigs, male and sow should be raised separately, and there should be a circle of pigs. The sow pen is equipped with a fence, an automatic water dispenser and an infrared lamp. In terms of disease prevention and control, Wujin pigs raised by farmers were immunized with classical swine fever, and at the same time, diseases such as pig lung disease, erysipelas and streptococcus were immunized in a planned way to repel insects in time. Once an epidemic occurs, it is necessary to immediately report to the township veterinary department, ask the veterinarian for diagnosis and treatment, and take comprehensive prevention and control measures to reduce the number of pig deaths.
