Doing a good job in summer broiler production, in addition to taking adjustments to the structure of the diet, changing feeding methods, improving the health of chicken coops, and strengthening comprehensive management measures such as prevention and control of epidemics in order to achieve maximum economic benefits from broiler production, reducing broiler house temperatures is a summer for broilers. The foundation and key to breeding. The temperature of broiler houses is based on the principles of application, convenience, and economy. Resources such as wind, light, electricity and water are fully utilized. Different technical measures are adopted to achieve the desired cooling target. 1. Ventilation and temperature reduction Before the temperature rises in the morning, close the doors and windows of the chicken house. Open the doors and windows after the temperature drops in the evening, exchange the air inside and outside the house, and improve the air quality in the house. The ceiling of the house should be equipped with a fan to cool the air. 2. Shading and cooling When constructing a chicken house, two rows of poplar trees are planted on both sides of each chicken house. Poplar trees cover the sunlight that illuminates the house and can lower the house temperature by 3°C~8°C. , can also improve the environment around the chicken house. It is also possible to plant plants such as creepers and loofahs, so that these plants can be covered with roofs, and generally the temperature of the house can be reduced by 2°C~3°C. Shade nets can also be used to cool the sunshade. The sunshade nets must be more than 50cm above the roof of the chicken house. The bamboo nets and wooden poles should be used to support and fix the sunshade nets to prevent the windshield and rain from damaging the shade nets and generate noise and affect the growth of broilers. 3. Cooling the water curtain Set the water curtain at the air inlet to allow the hot air to cool before entering the house. The lower end of the water curtain must not be lower than the height of the chicken bed, and the width can be narrower than the width of the house. The other end of the house is equipped with an exhaust fan. When the curtain is used, it can be opened before the temperature rises and closed after cooling in the afternoon. In this way, the temperature can be reduced by 3°C~6°C. 4. The temperature drop of the water hose is flattened on the broiler bed with the drought-resistant plastic water hose, and is sigmified according to the direction of the chicken house. The distance between the water hoses is determined according to the width of the chicken bed and the density of the broiler. Generally, the distance between two water belts should be more than 70 cm. When the temperature of the chicken house exceeds the growth temperature of broilers, it begins to fill the water zone with groundwater. The higher the temperature, the more water in the water zone will be maintained, and the faster the groundwater will flow. When the temperature in the house is high, the broilers are close to the hose and can save money. Generally can reduce the temperature around 10 °C, but also keep the house dry. Broiler farmers can use one or several cooling measures to achieve the cooling effect while minimizing investment and reducing costs based on broiler age, breeding density, housing environment, and existing conditions.
