The suitable temperature in autumn is a good time for broilers in plastic greenhouses. After a busy fall, nothing else is a good time for broilers to make money. The peasant friends who intend to raise broilers to make money after the fall are now ready to make preparations:
1. Shed sites The sheds that choose to keep chickens can be built directly in their own winter duty fields. Choose land plots that are open, well ventilated, close to water, free from pollution, and free from noise. Orchard vegetable fields and floodplains can be used. The abandoned vegetable greenhouses can also be raised after the reconstruction.
Second, the greenhouse structure is currently used more generally double inclined greenhouse, shed length 20 to 30 meters, width 7 to 8 meters, was east-west or north-south direction, construction area of ​​140 to 240 square meters, can be kept broilers 1000 to 1500 only.
The plastic film covering the greenhouse 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, leaving the gable at the other end only to leave ventilation holes or install windows, but also to leave 1 or 2 furnace holes for brooding or warming. 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 was used to fasten the knots. Each section was spaced 30 to 40 centimeters apart and was tied around the vertical columns to form a transverse bracket at the top of the greenhouse. In this way, a complete greenhouse scaffold was built.
The plastic film is adhered in advance according to the length and width specifications. When the film is covered with weather-free weather, the first layer of non-drip film is covered with 10-20 cm thick straw, other weeds or grass rakes, plus a layer of ordinary plastic. The film is moored and anchored by vertical and horizontal wires, and is finally covered with a layer of grasshopper or oiled paper. At the top of the shed, an adjustable vent hole with a diameter of 40 to 50 cm is installed every 3 to 4 meters. Drain the ditch around the shed. In this way, a plastic greenhouse capable of raising 1,000 to 1,500 broilers was built.
Third, equipment maintenance Into the young before, complete or overhaul the equipment used to install the drinker in advance, adjust the water level and flow, with a full tray.
Fourth, feed, medicine and whole material preparation According to the formula requirements, prepare a variety of feed ingredients, ready to feed with the ready-made feed. Commonly used vaccines and disinfectants should be fully prepared. The litter should be dry and kept soft, dry and clean.
V. Strictly sterilized brood chambers 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.
6. Pre-heating Pre-heating the greenhouse 1 week before pick-up, so that the temperature reaches 35°C. Three hours before the chicks were placed, the drinking water and the starter material were placed in the room and preheated.
YokeLink Automatic Splice Rated to hold a minimum 95% of RBS of the strand used, can ensure quick and reliable overhead tension splice with fast and easy installation. The conductor simply slips into color-coded, funnel-shaped end piece and enters the pilot cap automatically with a simple push.
