Implement the joint operation mode of "company+base+specialized households+direct stores". The base has cultivated 1 local pig seedlings, which are stocked by farmers in the production areas of pollution-free agricultural products of the company. The origin is orchards and hillsides, with beautiful environment, fresh air and no industrial pollution. Farmers adopt traditional feeding methods, feeding in stages, and feeding with soil materials such as sweet potato seedlings, corn, rice bran and wheat bran. The 1 local pig has large activity space, high exercise energy consumption, slow growth speed, and the slaughter time is about 1 year, so it is really raised with "three soils". The place of origin has strict sanitation, disinfection and epidemic prevention systems, and seedlings, feed and veterinary drugs are provided by the company. At each growth stage of the feeding process, the company arranges professional veterinarians, nutritionists and nurses to supervise and guide on the spot to ensure that there is no pesticide residue, no drug residue and no hormone residue in the raised soil pig No.1, and to ensure reliable raw materials for the hot fresh meat of the soil pig No.1.. In addition, all the sewage and dirt produced in the process of 1 pig breeding are treated harmlessly by the company, turning waste into fertilizer and returning it to the field to maintain and maintain the balance of the ecological environment. In a word, the purpose of 1 local pig breeding is to create social benefits, while pursuing economic benefits, it also takes into account ecological benefits.
