China is a big producer of pork, but pork exports are extremely limited. It exports only a small amount of pork to countries such as Russia every year, but exports to the EU and Japan are very difficult. The main reason is that the quality of pork products in China does not meet the requirements of importing countries. The reasons for this problem are environmental pollution, poor feed safety, and excessive drug residues. Therefore, it is of great significance to develop a pollution-free pig industry and comprehensively improve the quality of pork products in China in order to ensure consumer safety, participate in international competition, and promote the sustainable development of the pig industry. The so-called “pollution-free pork†refers to pork products that have been certified to be eligible for certification because of the environment, production process, and product quality that meet the relevant national standards and specifications. Only under the conditions of standards and regulations, scientific production methods can effectively produce pollution-free pork products. Creating a good environment 1. The pig house should be built in a place with high dryness, good drainage, and easy organization of epidemic prevention. The site site should meet the requirements of the local land use planning. There are no large-scale chemical plants, mines, leather, meat processing, slaughterhouses or other livestock farm pollution sources around 3 km. 2. The pig farm is more than 1km away from the main roads, railways, towns, residential areas and public places. There are fences or epidemic prevention ditch around the pig farms, and a green belt is established. 3. The pig farm production area is located in the upwind or sidewind direction of the management area. Waste manure treatment facilities and dead pigs should be disposed in the downwind or sidewind direction of the production area. 4. The cleanliness of the site area and the sewage are separated and do not cross each other. 5. The pig house should be able to heat insulation, the floor and the wall should be easy to clean, and can be disinfected with disinfectant such as acid and alkali. 6. The temperature and humidity in the pig house should meet the needs of pigs at different physiological stages. Such as piglets 27 ~ 32 °C, pigs 11 ~ 17 °C, relative humidity 80%. 7. The pig house is well-ventilated with toxic and harmful gases in the air: ammonia 25 mg/m3, hydrogen sulfide 10 mg/m3, carbon dioxide 1500 mg/m3, respirable particulates 1 mg/m3, total suspension Particulate matter 3 mg/m3, 70 dilutions of suffocation. 8. The quality of pig drinking water should meet the requirements of NY5027 "Poultry Drinking Water Quality". 9. The pig farm shall establish waste storage facilities to prevent leakage, overflow, and suffocation from causing environmental pollution. Waste disposal shall be reduced, harmless, and recycled. The manure should be used as an agricultural fertilizer after being deposited and released. The sewage should be used as a liquid fertilizer after fermentation and precipitation. Choose a good variety 1. Good breeding pigs should be introduced from breeding pig farms that have business licenses for breeding pigs, and quarantine inspections should be conducted in accordance with GB16567 "Specifications for the Regulation of Breeding of Domestic Animals and Poultry." The introduced breeding pigs are isolated and observed for 15 to 30 days. After veterinary inspection has determined that they are qualified for health, they can be used for breeding. 2. Finishing pig production should be produced in the following hybridization mode. One is to use three-way hybrids such as Duroc, Landrace, Yorkshire and other fine lean pigs to produce fattening pigs. The second is the use of Duroc, Landrace, Yorkshire and other fine lean boars and local thoroughbred sows to carry out three-way hybridization to produce cross-fertilizer fattening. Third, the use of supporting systems (Dika pigs, PIC pigs, etc.) to produce fattening pigs. Ensure feed safety The feed ingredients, additives, batch materials, concentrates, premixes, and the allowable amount of microorganisms shall meet the requirements of GB13078 "Hygiene Standards for Feed". 2. The nutritive feed additives and general feed additives used in the feed shall be the varieties specified in the Catalog of Approved Use of Feed Additives and the new breed of feed additives with the standard designation of the pre-production product as published by the Ministry of Agriculture of the People's Republic of China. 3. The use of pharmaceutical feed additives shall be implemented in accordance with the "Standard for the Use of Pharmaceutical Feed Additives" promulgated by the Ministry of Agriculture of the People's Republic of China. The use of pharmaceutical feed additives should strictly implement the withdrawal period system. 4. It is forbidden to add β-agonists, sedatives, hormones, and arsenic in feed. 5. High-copper diets should not be used for fattening pigs. The content of copper in compound feeds of pigs under 30 kg body weight should not exceed 250 mg/kg; the content of copper in compound feeds of 30-60 kg body weight should not exceed 150 mg/kg. Kg; copper content in compound feeds for pigs weighing more than 60 kilograms should not exceed 25 mg/kg.
