What should I pay attention to when raising chickens in plastic greenhouses?

Native chickens raised in plastic greenhouses have obvious advantages, low cost and less investment, and are easily accepted by farmers. Convenient demolition and site selection greatly reduce the spread of infectious diseases. Convenient management and simple feeding. Labor productivity is high, flexibility is great, turnover is fast, and time is short. Farmers can organize production freely according to the mayor/market situation. 1 s barrier shed is far from the village, so it is advisable to choose a hillside with convenient transportation, shelter from the wind, high terrain, sufficient water, easy management and a slope below 25 degrees. The warehouse should face south, with doors in the east, doors in the west, windows in the north and windows in the south. The construction of the second plastic shed follows the principles of economy, convenience, flexibility and local materials. The main building materials are bamboo, plastic film and sunshade, generally 132 square meters. The henhouse is 22 meters long, 6 meters wide and 2.0~2.5 meters high. The inside of the henhouse is supported by bamboo, surrounded by plastic film and sunshade net, and each bundle can raise 2000 kilograms.

To meet the humidity and ventilation conditions of the warehouse, chickens in plastic greenhouses usually have high humidity and wet ground, so the ground should be covered with fine sand, the surface should be covered with chaff, and the cushions should be replaced frequently. The temperature in the barn is high at noon, so it should be ventilated at lunch time. On the one hand, this method can promote ventilation in the warehouse, on the other hand, it can maintain normal humidity and temperature. According to the intensity of air stimulation and the temperature in the warehouse, the bottom of plastic film is rolled up in early summer, middle summer and late summer, and air holes are opened for ventilation. Ventilation time in winter is 7-8 am and 2-3 pm. Before ventilation, the furnace burned brightly 1 hour. The ventilation time shall be controlled at 10~20 minutes. There is less moisture and harmful gas in the feeding stage, so it is enough to keep the ventilation time at about 10 minute, and gradually increase the ventilation time according to the growth of chickens. The local chickens are growing gradually, and the feeding density in the henhouse is very high, so it needs ventilation at any time.

Choose healthy chicks that are agile, loud, shiny and not dense every day. After the shell comes out, it is inoculated with Marek's disease vaccine and transported to the chicken farm within 24 hours. After the chicks are hatched, they should do a good job of heat preservation, give enough light, and raise 40~50 chicks per square meter. Chickens should drink water before feeding, feed them with whole grain feed, and add antibiotics to the drinking water for 3 days to enhance their physique and improve the disease resistance rate. The indoor temperature of coffee bean membrane is kept at 32 ~ 35, and then it drops by 2 per week. After 25~30 days, the animals will be gradually defrosted and grazed, and they will be fed in plastic greenhouses at night. In fact, raising chickens in plastic greenhouses is a way of grazing and grazing, mainly depending on the temperature, the size of chickens and sunny and rainy weather. If local chickens are 1 month old, they should be given priority, supplemented with grazing and strengthened with heat preservation. Grazing mainly depends on supplementary feeding.

Full-price feed can be raised in the early stage, and coarse feed such as staple food and corn can be replaced after grazing in the later stage. Grazing and feeding roughage can give full play to the advantages of good adaptability, strong disease resistance and strong predation of local chickens, reduce feeding costs and improve meat quality. In the southern region with heavy rainfall and high humidity, even if the temperature of chickens drops, it is necessary to strengthen feeding. At this time, ventilation and density are the key to feeding. Dealing with these problems can effectively avoid various complications caused by respiratory tract. Although there are few diseases in raising chickens in plastic greenhouses, they should be vaccinated together with the occurrence of local infectious diseases in accordance with the principle of comprehensive prevention and prevention of critical diseases and the immunization procedures of chickens. In addition, according to the actual situation of raising chickens in mountainous areas, at the age of 15~60 days, insect-repellent drugs or traditional Chinese medicine should be used alternately to repel insects. After stocking 15~20 days, take the insect repellent once a month.

Prevent the occurrence of local chicken nematodiasis. The chickens raised in plastic greenhouses have high humidity and large circulation, so disinfection measures should be strictly implemented. First sell chickens, then clean and disinfect the mats and excreta in the plastic shed, then disinfect them with formalin and potassium permanganate, and carry out necessary fumigation. After disinfection, 2% ~ 3% volcanic ash is sprayed inside and outside the greenhouse. Before the chickens enter the henhouse, sprinkle a proper amount of quicklime powder on the floor, and then spread sterilized dry materials on the floor. Regularly clean, strictly disinfect the sink and sink, and do a good job of rat prevention. Conclusion In recent years, the technology of raising chickens in plastic greenhouse has been applied by more and more farmers. When farmers build plastic greenhouses, they should set up suitable warehouses in the local area to ensure the practicality and firmness of the greenhouses. Pay attention to strengthen the insulation effect, ventilate in time, ensure sufficient lighting, prevent disinfection and common infectious diseases in the process of breeding, and achieve good economic benefits.
