Simple plastic greenhouses have low investment and can be built in wastelands, forests, etc., and do not occupy farmland. Currently, it is the main way for broilers to be raised in rural areas. Broiler chickens in the winter and spring season are prone to respiratory diseases. In order to raise broilers, the following points may be noted: Greenhouse construction technical requirements Shelter site selection and specifications Shelter sheds should be selected so that the terrain is dry and close to water sources, and where there is no pollution, arable land is generally not used. It is better to use east-west to facilitate ventilation and lighting in winter and spring. It is generally 20 to 30 meters long, 2.2 to 2.5 meters high, and 8 to 10 meters wide, arched. Greenhouse materials and build up to build a 30 m long, 10 m wide, 300 m2 greenhouse generally requires 800 cm diameter bamboo sticks and 2 cm bamboo poles; 50 kg plastic film; 8 cm above diameter, 1.5 m long and 2.5 m stakes or There are 30 cement prefabricated bars, and iron wire, wheat straw, and linoleum are required. Semi-permanent greenhouses and leeward surfaces need to be made of concrete hollow bricks. The site is leveled and raised 15-20 centimeters above the surrounding ground before the formation. When setting up, firstly, the wooden stakes or cement strips should be 1.5 meters along the left and right sides of the center axis of the site, and should be erected every 2 meters, symmetrically and symmetrically. Secondly, use thick bamboo poles in vertical and horizontal position and use iron wire to secure it and fix it on the stake. It is advisable to use bamboo poles 30 cm apart. Then, the plastic film is affixed, and the film is covered with 15-20 cm thick wheat straw. After being flattened and compacted, the upper layer is covered with linoleum. The use of grasshoppers on the sunny plastic film facilitates lighting. There is a vent hole every 3 meters above the arch roof. Around the plastic film to be properly extended to facilitate folding and sealing the greenhouse. For the convenience of brooding, an underground back dragonfly can be established at one end of the shed, and a double-layer plastic film is used to separate it from the production shed area for a brooding room. Feeding management Cold and heat stress is the main cause of respiratory disease in broilers. In recent years, respiratory infections of broilers are extremely common, with heavy urgency, high incidence in winter and spring, and widespread onset around 20 days of age. Cold and heat stress are the main reasons, so it is important to control them well. Greenhouse temperature. During the day, fully utilize the temperature of solar energy and poultry to increase the temperature of the shed. In the evening, artificial warming is performed using temperature-raising equipment. When the brooding hen house needs to be pre-heated, the temperature in the house should reach 33~35°C, the brooding temperature should reach 35~37°C, and keep 25~30°C in the middle and late period. The furnace can be less coal-fired, but it must not be turned off. There is hot air ventilation for hot blast stoves. Strengthen ventilation and keep air fresh. Because broilers grow fast and have a large amount of breathing, fresh air should be sufficient to ensure oxygen supply. Otherwise, the occurrence of respiratory diseases and the occurrence of ascites and sudden death syndrome will cause losses to chicken farmers. To this end, we must strengthen ventilation. Especially when the winter and spring seasons are cold, we must handle the contradiction between ventilation and ventilation. The ventilation and ventilation time should be around noon, and the temperature inside and outside the house is relatively high. At this time, ventilation and ventilation will not reduce the temperature inside the house. Ventilation ventilation can be properly opened to reduce the concentration of harmful gases such as ammonia gas, hydrogen sulfide and carbon dioxide in the shed, keep the shed clean and sanitary, and ensure the normal growth and development of chickens. When ventilating and ventilating, pay attention to the angle of the air inlet. The wind cannot be blown directly onto the chicken. An exhaust pipe can be installed every 3 meters in the middle of the roof, which is about 2 meters long and 30 to 40 centimeters in diameter. An unpowered fan can also be installed every 3 meters above the roof. At the same time pay attention to anti-thief wind, chicken coops import and export hanging thick cotton curtain, the greenhouse should be sealed around. In the later period, the chickens eat more and excrete more. The air in the house is polluted and the odor is large. The amount of ventilation and ventilation should be increased. Warm up when ventilating and guard against flocking. Pay attention to moisture removal Due to the tightness of the plastic greenhouse, it is easy to cause excessive humidity in the greenhouse and affect the growth of broilers. Therefore, pay attention to humidity and moisture. The first is to prevent the waterline from leaking; the second is to remove the excrement and replace the litter in time; the other is to put the appropriate amount of quicklime and dry soil as moisture absorbers so that the humidity in the house can be maintained at 55% to 65%. Feeding chickens on the Internet online as much as possible can reduce faecal contact and reduce the chances of epidemic infections. It is particularly conducive to the control of coccidiosis and intestinal diseases. Chicken manure is leaked under the net to facilitate timely removal and reduce harmful gases at the same time; chickens are raised on the Internet to facilitate air circulation and prevent moisture. In terms of ventilation and ventilation, online feeding is also better than the ground level raising. In the sanitation and disinfection sheds, outsiders should be prevented from visiting, especially other farmers, feed, veterinary drug salesmen and chicken dealers. Pay attention to the timely removal of feces, keep chicken utensils clean and the breeders themselves clean and hygienic, in order to reduce the number of chicken disinfection. Greenhouse can import and export sterilized blankets or disinfection basins, and should be disinfected when working. Attention to Fire and Gas Poisoning Every year in the winter and spring seasons, there are accidents involving chicken sheds and gas poisoning. Therefore, we must pay attention to safe production, and pay attention to fire prevention and gas prevention.
