Pig Farm Design Considerations

The long-term development of pig farms depends on the initial planning and design. A reasonable and scientific plan is crucial to ensure the biosecurity of the pig farm and achieve sustainable development.

I. Site Selection for Pig Farms
Selecting an appropriate site for a pig farm is of utmost importance, as it significantly impacts the later stages of disease prevention, the health and growth of the pig population, and the efficiency of the staff. Comprehensive considerations should be made, including terrain, orientation, water and electricity supply, transportation, natural environment, and disease prevention.
1.Terrain: The site should have open terrain, making it easier to construct pigsties and minimizing the amount of work required to clear the land before construction.
2.Ecological Circulation: Pig manure can be used to form an ecological cycle with surrounding farmland, fish ponds, and gardens, as pig manure is an excellent organic fertilizer. This approach can help reduce random disposal of manure and save on fertilizer expenses.
3.Convenient Transportation: Easy access to transportation is crucial for a pig farm, as large-scale operations require daily input of feed and efficient transportation of livestock.
4.Safety Distance: The pig farm should be located at least 1 kilometer away from urban areas, residential areas, major roads, slaughterhouses, and other livestock farms.
5.Water and Electricity: The daily demand for water and electricity at a pig farm is substantial. The pig population requires a large amount of water for drinking, and large-scale pig farms are equipped with complete pig farming facilities that require power supply. Many large pig farms also need backup power generators to supplement the unstable grid supply.
II. Farm Planning
1.Zoning: The farm should be divided into production areas, management areas, isolation areas, etc. Depending on the local monsoon climate, the management area can be placed upwind or crosswind from the production area, while the isolation area should be located downwind or in a lower position relative to the entire farm. The arrangement of pigsties in the production area should follow this order: boar sties, sow breeding sties, pregnant sow sties, farrowing sow sties, nursery sties, and growing-finishing sties. The growing-finishing sties should be located near the entrance of the farm for easy exit of the pig population.
2.Waste Management: Pig manure can be processed into organic fertilizer through biogas production or composting after harmful microorganisms are eliminated, contributing to significant environmental benefits.
3.Building of Pigsties: The roofs of pigsties should be relatively thick, generally not less than 10cm, to provide good insulation. In China, pigsties should face north and south to facilitate ventilation and lighting. Disinfection pools should be constructed at the entrance of the factory, production area, and pigsty entrances, with a length not less than 1.5 times the circumference of a wheel and a depth of 15-20cm. The production area should also be equipped with changing rooms, UV disinfection, and disinfection pools.
4.Production Process: The production process should be streamlined, with planned arrangements for the entire year's pig farming, including breeding, pregnancy, farrowing, nursing, rearing, growing-finishing, and sales.
In addition, attention should be paid to disease prevention and disinfection, enhanced farm management, and improved breeding and weaning rates for piglets. Strict management systems should be implemented, and precise feeding management should be carried out. Controlling the flow of personnel and ensuring proper disinfection of people and vehicles entering and exiting the farm is essential.
