Improve the environment inside and outside the house
Strengthen the roof insulation and ventilation inside the house. Increase the insulation effect, reduce the introduction of radiant heat, and lower the temperature inside the house. Common measures are as follows: 1 layer of 10 cm to 20 cm thick straw or bark is placed on the roof. Spraying with groundwater at about 9 o'clock and 12 o'clock every day can significantly reduce the temperature inside the house. This method is suitable for tile roof, asbestos tile surface and other roof structure with a stable type of chicken house. Cooling groundwater is sprayed on the roof through the water pipe, reducing the tile surface temperature and interior temperature. However, care must be taken to spray water through the asbestos tiles and walls before the sun is hot. According to the length of the house, a number of “horn fans” are installed to ensure that wind energy is blown through all corners, and the ventilation area is not enough and there are no dead spots where the wind is not blowing.
Do a good job of greening and shading. Planting climbing vines in the chicken farm, planting morning glory and ivy around the asbestos sheds, allowing them to climb onto the roof to form a green heat insulation layer, which can effectively reduce the temperature inside the chicken house. Planting fast-growing forests on the playground around the hen house, such as fast-growing deciduous trees such as Italian poplar, can also play a role in providing shade and summer heat. In the case where the trees on the playground are relatively small or small, it is necessary to artificially construct a pergola. For a large number of trees in the playground, a pergola must also be constructed. In summer, farmers should shave the storage tanks and exposed water pipes to prevent sunlight from escaping the birds to high-temperature water. The farmers are required to diligently pump cool groundwater to the water storage tanks to prevent the water temperature in the pools from being too high. The water pipes are buried deep underground or used. Other methods shade the sun to reduce the water temperature.
Strengthen feeding management
Change feeding and water supply methods. Promote the combination of homes and sports field feeding; more feeding wet materials, less feeding Tim; feeding more at low temperatures or at night, feeding less at high temperatures; feed added garlic and other ways to increase feed intake. The management of good litter, the general chicken litter thickness control in 2 cm ~ 3 cm, compaction to be replaced in time, especially fast chicken. In the rearing process, the litter gradually becomes thinner as the chicken grows. In the summer, big chickens do not want to move around, and they can use plastic basins to provide drinking water. In addition, as little as possible to add odor, bitter drugs (such as gentamicin, etc.) or noon medication, so as not to affect the amount of water the chickens. Starting from the chicken, first spray with peracetic acid sprayer, spray 2 times a day, spray once every 0.5 hours to 1 hour, and often go around in the house, drive chicken standing, easy to body heat distribution.
Control the density of chickens and increase ventilation. In the summer, the breeding density should be adjusted according to the condition of the breeder house and the greening of the sports ground. Do not blindly ask for more. In addition, the time for the summer expansion should be based on the temperature, should be faster than other seasons, a larger range. The house can be led out of the house to reduce the density of the house. Good ventilation will directly take away a lot of heat from the chicken body, which will bring about a cooling effect. Therefore, ventilation and ventilation work must be done. To increase the ventilation of plastic film, etc., and open all windows, doors, windows and skylights to enhance ventilation. Hot fan devices are turned on at noon and noon to increase air flow.
