The appropriate temperature in the autumn is a good time for broilers in plastic greenhouses. After the fall, farmers who plan to raise broilers to make money are now ready to make preparations:
Shelter selection
The shed for broiler chickens can be built directly in their own winter duty field. Choose land plots that are open, well ventilated, close to water, free from pollution, and free from noise. Orchard vegetable fields and floodplains can all be used. The abandoned vegetable greenhouses can also be reared after the reconstruction.
Greenhouse structure
At present, more commonly used double inclined sheds, shed 20 to 30 meters long, 7 to 8 meters wide, was east-west or north-south direction, construction area of ​​140 to 240 square meters, can be kept broilers 1000 to 1500.
The plastic film is 1 meter longer than the shed and 2 meters wider than the shed. According to the shed length of 30 meters and raising 1,500 chickens, it takes 200 bamboo rafts that are 4.5 meters long, 20 bamboo rafts that are about 8 meters long, and about 2,500 bricks. In addition, prepare a proper amount of string, wire, wheat straw or grass rake.
Both sides of the greenhouse have brick walls, one end of the gable leaving the door, leaving ventilation holes on both sides, and the other side of the gable only to leave vents or install windows, but also to leave 1 or 2 furnace holes for brooding or warming use. A row of columns is planted every 2 meters between the two brick walls. The middle one is the same height as the roof, and two on the left and right sides (including two outside and the outside of the shed), a total of five, so that the vertical column There are 5 rows. Attached to the top of each row of longitudinal columns with 8 meters long bamboo poles constitute the longitudinal bracket of the greenhouse. Then a group of bamboo poles with a length of 4.5 meters is used to fasten the knots, and each section is spaced 30 to 40 centimeters apart and is tied around the longitudinal columns to form a transverse bracket at the top of the greenhouse. In this way, a complete greenhouse scaffold was built.
Strict disinfection
Brooding rooms and all appliances must be thoroughly cleaned and strictly disinfected. If it is a sealed brooding room, it is finally fumigated with formalin. 25 ml of formalin and the same amount of water per cubic metre of space are placed in an enamel pot and then 12.5 g of potassium permanganate is added. Fumigation, opening the doors and windows for ventilation after 24 hours of closed sterilization. Once sterilized, personnel do not need to go in and out.
Preheating
The greenhouse was preheated for 1 week before picking to allow the temperature to reach 35°C. Three hours before the chicks were placed, the drinking water and the starter material were placed in the room and preheated.
