Second, the main insulation, supplemented by ventilation.
Only when the temperature required by the flock is guaranteed can ventilation and humidification be considered again.
Insulation method: 1, the chicken house should be closed: windows, walls, fan mouth, side air inlet, grid crossbar and wall junctions, doors, etc. must be completely rectified, do not leak a trace of wind, with yellow mud mixed with gray outside Smooth.
2. The furnace is normal: 1) The furnace is strictly inspected one week before entering the chicken to prevent the gas leakage from the furnace pipe, and the furnace temperature cannot be drawn to the rear end of the house. 2) The induced draft fan has no fault. 3) Coal burning should be easy to burn and lasting firepower.
3. Pre-heating for 4-5 days before chicken enters, so that the articles in contact with chickens such as walls, mesh, etc. in chicken coops are warmed. After the chickens enter the house, the temperature is normal and the chickens are distributed.
4, personnel skilled in the operation of the furnace. Ensure the normal operation of the furnace.
Third, the chicken house temperature: the principle of high before and after the low, that is, the temperature before and after the gradual increase of 1-2 °C key: the consistency of the former mid-afterwards gradually increased, should avoid the temperature difference between before and after the middle low or high.
Method: 1. The main air inlet is the front end, accounting for 60-70% of the entire air intake area. 2. As long as the temperature of the rear end is lower than the temperature of the front end, the inlet of the front end should be enlarged until the rear end temperature is raised. Myth: Increase the ventilation or ventilation time. It is wrong to pull the front end temperature to the back end. 3, side window inlet: easy and less easy: In the case of the front of the furnace at the entrance to the main case, the middle of the place where the temperature is high, that is to add a side air inlet. The air inlet is sized to adjust the temperature here to the low and high mode. 4, remember: Which point is low temperature, reduce the air inlet. Which point the temperature expands into the air inlet here. 5. The overall temperature of the house is regulated by the amount of ventilation (ventilation time and size of the fan), and the local temperature (temperature difference) is adjusted by the size of the air inlet.
Fourth, the air inlet protection:
Purpose: After the pre-warmed cold air enters the house, it comes into contact with the chickens. Keep the chicken house free from cold. Remember: The air inlet is not effectively protected rather than open.
1. Method: The outside allows the natural wind to not freely enter the shed. The inner circumstance is that the cold air enters the middle and upper part of the shed.
2. The distance from the air inlet on the side of the coop: 1) Open 60-70 meters in the middle of the 20 meters before and after the house. 2) Use a plastic cloth or bag to make a 2-2.5m long hollow pipe. One end is closely connected with the side air inlet, and the other end is suspended in the middle of the house. It is required that the middle of the pipeline does not leak outward and is in a natural hollow state.
V. The size and quantity of the air inlet opening: 1. The front end (the air inlet at the hearth furnace) can be 1-2 side windows, and the size is subject to the adjustment of the interior temperature mode. 2. Side air inlet: (15-30 days old) One every 10 meters in the middle of 60-70 meters. The size of the air inlet is based on the adjustment of the local temperature. After 30 days of age, add another 5-7 on both sides to protect the air intake.
6. Opening time of the air inlet: 1. Air inlet at the ground floor: Once the fan is exhausted, it begins to open. 2. Side air inlet: 1) Generally after 10-13 days of age; 2) When the local temperature is higher than the front and rear temperature of 2°C; 3) When the local temperature is high but the air is stifled.
Seven, ventilation and time:
1, the amount of ventilation
1) Based on the principle of minimum ventilation, the minimum ventilation volume = storage capacity * single weight average weight kg / only * 0.015m3/kg. 2) The principle of gradual increase in the ventilation volume as the flock grows older is prohibited.
3) Ventilation rate to ensure the temperature in the house is the principle.
2. Ventilation time: 1) The fan starts at 3-5 days old. 2) The principle of short open and short stop. 3, fan use and replacement: 1) 0-20 days: 300m3 exhaust fan can be. 2) Replace 550m3 at 20-25 days old
Half of the exhaust fan or 750m3 exhaust fan 1/3. 3) Replacement method: a: One building is overnormal and then the other is over. When it is excessive, it is observed on site for 12-24 hours. b: When the exhaust fan has a large amount of exhaust air, the exhaust port is closed with bricks, and the ventilation volume is increased by the corresponding method of opening bricks and exhaust air.
Eight, the establishment of high-temperature area: 1, the front of the rack 10-15m left empty chicken, to be expanded after 30 days of use. 2. Set a curtain of 2m high at the doorway and a second curtain in the empty grid and brooding area. Keep in mind that it is not air-permeable with a plastic cloth or bucket hanging under the grid. 3, in the high temperature zone above the furnace pipe crane use reverse fan to expand the cooling rate of the furnace. 4. When the chicken is 30 days old to expand the fence, the second curtain should be moved to the front of the grid.
Nine, the use of reverse fans. When the chickens were 0-10 days old, two counter-fans were used. The interval was 20 meters and the air was fed to the rear end of the house. Ensure the heat dissipation and internal temperature balance of the furnace tube. After 10 days of age: The counter-fan is 10-15 meters away from the air inlet of the ground furnace and starts to blow forward synchronously with the exhaust fan.
X. Waterline management is the mainstay, and excrement is supplemented. The house was cleared of feces until the birds were 25 days old. Which section of the waterline will be leaked and which part of the excrement will be cleaned up.
11. Humidity: Before the 20th day of age, hot water is sprayed on the empty area of ​​the high temperature zone. After 20 days of age, use a single spray gun to spray 40-50°C warm water on each house for 400kg.
Twelve and 20 days prior to the high temperature area, chickens were extended to the end of the house. After 30 days of age, the chickens spread out to expand the entire chicken house.
