1. Selection of thermal insulation equipment
At present, there are several types of heat preservation equipment for pig farms, including hand tents, “houses in housingâ€, incubators, heat lamps, stoves or stoves:
Handing the tabernacle. The tent must be fixed from the bottom to the top. The height of the taber should be determined according to the weather conditions, indoor temperature, air quality, etc. The maximum clearance is 10cm to 20cm. Ventilation shall be provided to the tent. In a low way, put the leeward surface first and then put it on the wind surface.
"House in the house." Pull the wire rope at the height of 2 meters in the bar and pull the dense plastic film paper.
cooler box. With a length of 2 meters, a width of 1 meter, and a thickness of 0.1 meters, the whole board is bound to form a box on three sides, leaving an entrance and exit. The top layer is sealed with film paper.
Heat lamp. Each power is 250W, mainly in the incubator, the height is about 1 meter.
Hot stove. The start-up temperature, temperature stability, ease of operation, coal loss, and farmers acceptance of the hot blast furnace are all superior to traditional coal stoves (10 minutes to 20 minutes from the start, and the daily coal consumption per 300 hogs is 50 kg ~ 75 kg, the temperature difference between pigs 2 °C ~ 3 °C).
2. Usage of thermal insulation equipment
Insulation order. First outside and inside (Tentative - "House in the house" - box thermostat - heat lamp - stove).
Ventilation order. First inside and outside (insulation box - "house in the house" - tent). As far as possible to meet the appropriate temperature of pigs, flexible handling of the relationship between ventilation and insulation. Prevent low temperature and high humidity and try to ensure good air quality. Pay attention to keeping warm in the morning and evening, pay attention to ventilation at noon, and prevent the temperature difference between day and night being too large.
3. The specific method of operation
1. At night (especially during the second half of the night): The tabernacle, the "house in the house," and the incubator are basically closed. 2. In the morning: Open the film paper on the incubator to open the mouth to ventilate the incubator, and then open the air from the film on the walkway and the side of the excrement in the “house in the houseâ€. The tent, the heat lamp and the stove Temporarily unchanged.
3. Near noon: If the temperature gradually rises, first turn off the heat lamp in the column; at noon, after the temperature rises to the standard temperature, extinguish the fire extinguisher; after the stove is extinguished and some “houses in the house†are opened, the house is hot or smelly. When it is rich, you can lower the curtain on the wind-free or sunny side (the height of the taberth is higher than the "house in the house"). When the temperature rises, lower the wind surface and the "house in the house". The high position properly lowered the sunlit side of the tent to the height where the wind did not reach the height of the pig, or it was rather boring and lowered the curtain on the windward side to a height where the wind did not reach the height of the pig. The tent is placed in the end.
4. Feeding pigs: Every time you feed a pig, open the lid of the incubator and walk in the "house in the house" to change the air. You can also temporarily turn off the heat lamp. After the pig eats the food, it will be closed again. The age of the pigs is getting larger and larger. As the case may be, the "house in the house" at the end of the excreta is slowly opened to the middle, maintaining a certain fixed ventilation and ventilation openings.
5. Observe: When the tent, the house, the incubator, and the heat-retaining lamp are all under temperature control, the pigs also perform a pile-up phenomenon. If the temperature inside the house is low, it is necessary to use the stove in time to increase the temperature inside the house. .
6. When the house smells thick, it is necessary to properly open the "house in the house" ventilation, reduce the concentration of odor, and then properly lower the ventilation of the curtain on the lee side.
It is the key to selecting the heavy insulation equipment for pigs in winter
Temperature is the driving force for the growth of pigs. The appropriate temperature can not only promote the growth of pigs, but also prevent pigs from getting sick. Appropriate ambient temperature for pigs at each stage is: piglet 23°C 2°C, medium pig 20°C 2°C, large pig 18°C ​​2°C; piglet high temperature demand, freshly kept seedlings at room temperature at 20°C or above for the first week it is good. After 1 week, the room temperature was kept above 18°C ​​(including 18°C); the big pigs could be kept at 15°C or above at room temperature. (Note: Piglets under 15 kg are piglets; 15 kg to 30 kg are piglets; 30 kg to 60 kg are middle pigs; 60 kg or more are big pigs)
