    The suitable ambient temperature for each stage of the hog is 23 ± 2 ℃ for piglets, 20 ± 2 ℃ for middle pigs, and 18 ± 2 ℃ for big pigs. The temperature requirements of piglets are high, and it is best to keep the room temperature at 20 ℃ or above for one week after entering the seedlings. After one week, the room temperature should be kept above 18 ℃ (including 18 ℃); the room temperature of big pigs should be 15 ℃ or above. (Note: piglets below 30 kg are piglets; 30-60 kg are small pigs; 60-120 kg are medium pigs; those over 120 kg are big pigs.)

    First, the choice of insulation equipment

    At present, the pig farm's thermal insulation equipment mainly includes hand-cranked tents, "houses in the house", thermal insulation boxes, thermal insulation lamps, hot air stoves or stoves.

    Hand-cranked tent: The tent must be fixed at the lower end and pulled up from the bottom. The height of the tent should be determined according to the weather conditions, indoor temperature, air quality, etc. There is a gap of 10-20cm at the highest place for ventilation. The level is lowered, first the leeward side and then the windward side.

    "House in the house": Pull the iron wire rope at a height of 2 meters in the pen and pull the dense plastic film.

    Insulation box: A box of 2 meters long, 1 meter wide and 0.1 meter thick is bound to one box on three sides, leaving an entrance and exit. The top layer is sealed with film paper.

    Heat-preserving lamp: Power 250W / pcs. The size of the viewing room is correspondingly configured. It is mainly placed in the heat-preserving box with a height of about 1 meter.

    Hot blast stove: The hot blast stove's heating speed, temperature stability, ease of operation, coal consumption and household acceptance have greater advantages than traditional coal stoves (10-20 minutes starting temperature, 100-150 energy consumption per 300 heads) Kg coal / day, pig house temperature difference 2-3 degrees).

    Second, the use of insulation equipment

    1. Insulation sequence: first outside then inside (tents → houses in the house → ovens → thermal insulation lamps → stoves).

    2. Balance the relationship between insulation and ventilation. Ventilation sequence: inside and outside (insulation box → house in house → tent). Try to meet the appropriate temperature of the pig, and flexibly handle the relationship between ventilation and thermal insulation. Prevent low temperature and high humidity, and try to ensure good air quality. Stay warm in the morning and evening, and ventilate at noon to prevent the temperature difference between day and night from becoming too large.

    3. Specific operation method:

    (1) At night (especially in the middle of the night). The tent, the "house in the house", and the incubator are basically hermetically sealed.

    (2) Morning. First open the opening of the film paper covering the insulation box to ventilate the insulation box, and then open the film in the aisle and the side of the faeces for ventilation, the tent, insulation lamp and stove are temporarily unchanged. .

    (3) Near noon. If the temperature gradually rises, first turn off the heat-prevention lamp in the column; at noon, turn off the fire extinguisher when the temperature rises to the standard temperature; after the furnace is extinguished and some "houses in the house" are turned on, if the house is hot or the smell is strong, you can Lower the tent on the side that is not exposed to the wind or the direct sunlight (but the tent height is still higher than the "house in the house"). When the temperature rises, lower the wind surface and the "house in the house" in order. Position or lower the tent on the side with direct sunlight to the height where the wind can't blow the pig's body, or when it's sultry, lower the tent on the wind surface to the height where the wind can't blow the pig's body. Put the tabernacle to the end.

    (4) Feeding pigs. Open the incubator cover and the aisle "house in the house" for ventilation at each meal. You can also temporarily turn off the heat preservation lamp. After the pigs are finished eating, they will be turned off as cold. As the pigs age The larger, the house in the house at the end of the defecation opening is slowly opened to the middle, and a certain fixed ventilation vent is maintained.

    (5) Pay attention to observations. When the tent, house, heat preservation box, and heat preservation lamp are all under temperature control, the pigs also show a pile-up phenomenon. When the temperature in the house is low, it is necessary to use the stove in time to improve the house. temperature.

    (6) When the odor in the house is strong, it is necessary to properly open the "house in the house" for ventilation to reduce the odor concentration and then appropriately lower the tent ventilation on the leeward side.
