1. The shed pigsty is mainly made of greenhouses and plastics. The temperature inside the pigsty is increased by the sunshine outside. In cold places, pigs are generally raised in this way, such as the most common in the north. Usually this kind of investment is not much, and the effect is ideal. First, put the approximate frame of the pigsty on it with plastic.
2. Open pigsty is easier to build. Just put some wooden fences around it, which is very cost-saving and material-saving. Usually, this kind of lighting is better, and it is easy to eliminate harmful gases, but it also has some shortcomings. Because the pigsty is not closed, the temperature in the pigsty changes with the weather, which is not easy to control. This kind of pigsty is very cold, especially in the north, which is not suitable for breeding. Usually this kind of pigsty will be in a warmer place.
3. Closed pigsty is usually built in the form of single row, double row and multiple rows. Usually, its construction method is to set a corridor in front of each row of railings in one or several rows, and the pigsty is in the middle of the corridor. Usually, this kind of lighting is better, and the ventilation and moisture-proof effect is also very good, which is suitable for places with small temperature difference and not very cold in winter.
How to build a pigsty in rural areas should be decided according to the local climate. For example, the local winter is cold. Usually, this kind of pigsty is suitable for closed and greenhouse construction. If the local winter is not very cold, all three methods can be used.
Extended data:
1. pig farm location:
The site selection should be based on the nature, scale and task of the pig farm, taking into account the natural conditions such as topography, landform, water source, soil and local climate, as well as social conditions such as feed and energy supply, transportation, product sales, distance from surrounding factories, residential areas and other livestock and poultry farms, local agricultural production and pig manure treatment capacity.
2. Terrain:
The terrain of the pig farm requires openness and cleanliness, and the area is large enough. The production area of general pig farms can be considered as 45 ~ 50m2 for each breeding pig or 3 ~ 4m2 for commercial fattening pigs. Pig farms require high terrain, dryness, flatness, leeward and sunny, and gentle slope. Low-lying land is prone to water and humidity, poor ventilation in summer, hot air, easy to breed mosquitoes, flies and microorganisms, and cold in winter. The site with gentle slope is convenient for drainage, but the slope is not more than 25, so as not to cause poor traffic in the site.
3. Water quality:
The water source of pig farms requires sufficient water, good water quality, easy access and sanitary protection, and easy purification and disinfection.
4. Architectural layout:
The layout of pig farm buildings lies in the correct arrangement of the location, orientation and spacing of various buildings. The layout needs to consider the functional relationship between buildings, health and epidemic prevention, ventilation and lighting, fire prevention, land saving and so on. The location of the pig house in the production area needs to consider the convenience of breeding and herd transfer, and the breeding pigs and piglets should be placed in the upwind and high terrain.
The pregnant pig house and the delivery pig house should be placed in a better position, and the delivery pig house should be close to the pregnant pig house and the piglet feeding house. The breeding pigsty is close to the fattening pigsty, and the fattening pigsty is located downwind. Commercial pigs are placed near the boarding gate or fence, and pig platforms are installed in the fence.
5. Pig house construction:
The span of pigsty with natural ventilation should not exceed 12m, and the eaves height should not be less than 3m. The length of pigsty ventilated by water curtain fan should not exceed 60m, but the width can be unlimited. The height inside the pigsty should not be too high, and the ceiling height should be 2.5m Pay attention to the heat insulation and cold protection of the walls and roofs.
