The use of greenhouses to raise broilers is generally adopted by rural farmers because of their less effective investment. Broiler rearing in a greenhouse is generally conducted in two ways: raising and grounding. Raising, is to put up a shelf about 1 meter high in the shed, and then spread on the shelf with a plastic net for chickens, chicken, water, materials, etc. on the Internet. This method is suitable for use in winter. It can make full use of the principles of air thermodynamics. The air with high temperature is in the upper layer, so as to maintain the temperature of the chicken house. However, in the hot summer season, it is more suitable to adopt the ground-level raising method. Although the floor is covered with a certain amount of padding, the temperature of the ground is relatively lower than the temperature of the upper air. In spite of this, certain measures must be taken during the hot summer months so that broiler chickens can be kept safely in the hot season. 1, ventilation and cooling: through the air flow to achieve the purpose of cooling. Natural ventilation can be used. That is, vents are provided at the bottom and top of the shed to allow natural air flow. This method has a poor effect on the shed and the environment with higher temperature, so it is necessary to use mechanical ventilation when necessary to achieve the purpose of ventilation and cooling. Mechanical ventilation is based on the breeding density of the appropriate number of fans installed on the wall, through the fan to give ventilation, ventilation and ventilation purposes. 2. Shade and cooling: Cover the shade net on the top of the shed to avoid direct sunlight, so as to achieve the purpose of cooling. If one layer does not work well, you can cover two layers to achieve good results. 3, adequate drinking water: summer temperatures are high, the chicken body in order to reduce the temperature and metabolism will need a lot of water, so to ensure adequate clean well water for chicken drinking. 4, pay attention to health: due to high ambient temperature, a variety of viruses, bacteria are easy to breed, so to do a good job inside and outside the greenhouse disinfection health work. First of all, drinking and feeding utensils should be cleaned and disinfected every day. Second, the use of sprayer to prepare the appropriate disinfectant solution for chicken disinfection, on the one hand, can play a role in sterilization, disinfection, to avoid the bacteria, the role of virus breeding, on the other hand, even after spraying the water will also achieve the purpose of cooling. Then there is the disinfection of the shed environment. Because of the air circulation, viruses and bacteria in the shed environment can easily invade the shed. Therefore, shed disinfection should also be taken seriously, especially where there are sources of pollution, such as chicken manure that has been cleaned up, and disposal. Diseased chickens, dead chickens, etc., must be thoroughly cleaned and disinfected. 5. Strengthen nutrition: As the temperature is high, the feed at this time should appropriately reduce the content of energy feed (such as corn), increase the protein content appropriately, and because the high temperature during the day, the feed intake of the chicken is low, so it can be late at night and Feeding in the early morning.
