Farm site selection. The address of the farm should be sunny, flat, drained, away from traffic routes and densely populated areas.

Pig house construction. The design of pig houses should be scientific. Farmers can use double-row or single-row pig houses according to their actual conditions. The overall requirements for the pig house construction are that the pig house is cool in winter and cool in summer, and the area and shuttle are spacious, airy and transparent, the height of the pig house is more than 2.6 meters, and bright tiles are installed on the roof to increase the brightness.

Pig sty construction. Pork floor and wall construction materials should be sturdy and durable. Sanhe land surface and brick walls are generally used. Pig stumps should be spacious and bright, with an area of ​​more than 8 square meters (except for breeding pigs and commercial pigs with limited feed bar). The shed is flat without slipping and has a certain slope. The inside of the shed is leaky and the floor is easy to wash and remove the excrement to ensure the cleanliness of the shed. Automatic drinkers are installed in the circle to ensure that the pens are dry and provide clean drinking water for the pigs and reduce the labor intensity of the management personnel. Sow litter sets up piglet incubators to improve the survival rate of piglets, in addition to constructing piglet nursery rings.

Do a good job of water supply system construction. Drinking water, domestic water, clean water, etc. have a large amount of water. Pig farmers need to build water towers and do water supply system construction.

Faecal harmless treatment. Large-scale pig production, manure removal and disposal are very important. We must vigorously promote the storage of manure and sterilize biogas, implement harmless production, and promote the use of biogas to save energy and protect the environment.

Fully consider the layout of the building. The distance between the residential area of ​​human life and the pig house is generally more than 50 meters. In order to ensure the safety of people and animals, according to the characteristics of the wind direction, the living and residential areas are built on the top, and the middle is the pig house. The excrement disposal area and the sick pig isolation area are built in the downwind position.

Do a good job in file management. For large-scale swine production, archives records should be well documented, such as pedigree archives of breeding pigs, litter records of sow mating, disease and epidemic records, prevention and treatment programs and treatment outcomes, and pigs' entry and exit conditions, which will facilitate the guidance of future production and management.

Advantages of pasture planting. The feed is mainly composed of compound feed, supplemented by green feed. Therefore, it is necessary to fully consider the cultivation of high-quality forage grasses, such as ryegrass, comfrey, chicory, and red vine, in order to supplement the needs of pigs with vitamins and water.

Preventive measures. Due to the large number of pigs, the high concentration of pigs, and the frequent entry and exit of pigs, the work of hygiene and epidemic prevention is very important. It is necessary to formulate strict disinfection measures, do a good job in environmental sanitation and disinfection, and intensify the disinfection of epidemic-prone seasons. Lime, ash, and caustic soda can be selected as disinfectants. Strictly follow the scientific immunization procedures to do regular immunizations for epidemics. Every year in the spring and autumn, the piglet must be epidemic prevention. The sow should also take care of epidemic diseases such as parvovirus, pseudorabies, and colibacillosis. The piglets should be able to prevent epidemic diseases such as piglet paratyphoid and piglets yellow and white piglets. To strengthen immunity.
