What are the site selection methods for building a pig farm?
The pig farming industry is an important industry in our country's agriculture and plays an important role in ensuring a safe supply of meat. To develop pig farming, the first thing to do is build a pig farm, and the primary issue in building a pig farm is choosing the site. Scientific selection of the pig farm location is not only beneficial to management and operations, but also helps with warmth retention, lighting and disease control. Let's take a look below at the site selection methods for building a pig farm!
Terrain conditions
The pig farm site must not be too narrow and long or have too many corners. Otherwise, it will not be conducive to the rational layout of the pig farm buildings and will also cause inconvenience in transportation and management. The terrain of the pig farm should be neat and open, with sufficient area. The author once saw a pig farm that, because its own field was narrow and long, built a very long single-row pig house according to its own field. This not only required more investment in building the enclosure walls, but also made feeding, disinfection and other feeding management very inconvenient.
Topography conditions
The topography of the pig farm should be a place with high, dry and flat terrain, which is conducive to ventilation and air exchange and saves investment in ground treatment. Generally, it should also be above the local historical flood line, with the groundwater level below 2 m, and far away from swamps and places where mosquitoes and flies breed. In addition, there should be a certain gentle slope (generally a slope of 1%-3%) to facilitate drainage. In addition, attention should be paid to facing the sun to facilitate lighting and warmth retention.
Water source requirements
Water source has a vital impact on the pig farm. In the production process of the pig farm, the drinking water of livestock and poultry, the washing and preparation of feed, the washing of tools, disinfection, washing of animal bodies and so on all require large amounts of water. Therefore, the pig farm must have a reliable water source of sufficient quality that is easy to access.
Soil requirements
The soil for building a pig farm should have good permeability and air permeability, small water-holding capacity and hygroscopicity, weak capillary action, low thermal conductivity, good heat preservation, and no contamination or biogeochemical endemic diseases. Therefore, sandy loam soil should be the ideal choice. However, sometimes due to the limitations of objective conditions, the defects of the soil can also be made up for through building design and production management.
