In winter, when the temperature is low, the growth performance of pigs decreases, and the ratio of feed weight increases. If the pigs catch cold, they may cause colds, diarrhea, coughing, etc., and the poor warmth will seriously affect the economic efficiency of the farm. Therefore, the heating of the farm must be completed. Measures. The actual production of the best combination of local heating and thermal insulation and heating both to achieve the purpose of good economic and practical results. The use of golden crocodile dry-sweeping pigs can increase winter warmth.
The key issue in thermal insulation is the thermal performance of the structure of the pig house. The simplest method of insulation is to close the pig house, such as closing doors and windows, lowering the curtain, and blocking the air leakage. The use of materials can be selected according to the outdoor temperature. If the temperature is low, double curtains can be used, and a layer of wood or plastic film can be nailed outside the window to improve the warming effect.
There are multiple choices of heating facilities, which can be selected based on the actual conditions and economic conditions of the pig house:
1. Goldfish dry-type fermentation bed using the kingpin dry Fermentation Bed pig (see details), litter lower 40-50 °C fermentation, litter surface temperature above 20 °C, to ensure the warmth of winter pigs, The soft litter provides a comfortable environment for the pigs. There is no environmental pollution, and it is a way for the ecological environment-friendly culture supported by the country.
2. Coal-fired boilers Common coal-fired heating facilities are often used in areas where the weather is cold and the lump coal supply is adequate. The fuel used is lump coal. The advantage is that the heating speed is fast, and it is easy to move. It can be installed and used at any time and can be used for emergency in pig houses. The disadvantage is that the dust is relatively large and it is prone to produce carbon monoxide poisoning, which requires more management.
3. Honeycomb briqueties use briquette coal as fuel, and the heating rate and quantity are slower and less than that of coal stoves, but they are used in many areas of the country due to the convenience of smokeless use. The advantage is that it is easy to move and can be installed and used at any time. It is not necessary to install a chimney in emergency and is more convenient than a coal stove. The disadvantage is also prone to poisoning.
4. The fire wall made of bricks and other materials on the wall of the pig house is thicker and has better insulation properties. The fire wall is mostly used in colder areas. If the Timing port is located outside the pig house, it can also prevent coal. Smoke or dust and other adverse effects. The disadvantage is that the pollution is heavy.
5. The mantle designs the fire below the pig house. When the fire burns below, the ground maintains a certain temperature because the heat is radiated from the bottom upwards. The fire pot can maintain the proper temperature and can be kept at a low temperature in the pig house. When the temperature of the pig is guaranteed, the cost is greatly saved. In addition, the mantle can also be designed in the form of burning firewood. The fuel is cheap weeds or crop straws, which can reduce the cost to a lower level. In the straw-rich agricultural areas, the small pig farms have sufficient manpower. This form is Very affordable. The disadvantage is that the pollution is heavy.
6. Floor heating is similar to earthworms, but the difference lies in burying circulating water pipes in the concrete floor. When heating is needed, the boiler water is heated and hot water is pumped into the circulating water pipe in the concrete floor through a circulating pump to increase the temperature of the ground. This method is used on many pig farms and it works very well. It does not occupy floor space. Old-style pig houses are also very easy to remodel. If the insulation blanket is laid under the concrete floor to prevent the heat from being emitted downwards, part of the cost of burning coal can be saved.
7. The plumbing used by plumbing is similar to that used by residents. However, because the pigs are generally at a low level, the heat of water radiators is rising, the heating effect is general, and the investment is large. The area is also large, and the usage is decreasing.
8. Gas heating With water heating, the heating rate is faster, and it is easy to meet the requirements of various kinds of piggery on the temperature. The disadvantage is that the boiler workers have higher requirements and are not suitable for small-scale pig farms.
9. Plastic greenhouses Farmers use the most common facilities for pigs, with less investment and ease of use.
10. Electric air-conditioning investment, high cost, only emergency use.
11. Heaters, also known as livestock and poultry air conditioners, blow the heat from the boiler through a blower to the pig house. The temperature inside the house is uniform, clean and hygienic, and the price is much cheaper than electric air conditioning. Many large-scale pig farms are in use.
12. Infrared lamp is a good choice for local heating, suitable for emergency, especially in the new transfer to the pigs, easy to operate.
When using the above heating facilities, it is necessary to strengthen management to prevent the stove from affecting the health of the herd and avoid the fire, especially the wooden structure of the pig house, avoiding excessive humidity caused by the non-circulation of indoor air, as well as ensuring indoor fresh air, construction of water pipes and other facilities Smooth and uniform heating, strengthen the maintenance and management of air-conditioning and other facilities to avoid failure.
