The high temperature weather in summer frequently hits, and the heat has more and more adverse effects on the normal production of chicken farms. The feed intake of broilers decreases, the growth is slow, the weight gain decreases, and the laying rate of laying hens decreases, causing the price of eggs to rise. Therefore, in summer, special attention should be paid to the heatstroke prevention and cooling of the chicken farm. This will not only reduce the economic loss of the chicken farm, but also create opportunities for oneself and win the future when the supply is tight.
Heatstroke prevention and cooling measures is like "eighteen martial arts". Chicken farms need to choose the appropriate "kung fu" based on the actual situation, make full use of equipment, greening, buildings, water and other resources, and take different measures to achieve the cooling effect of the chicken coop. Maximize economic benefits.
Cooling Tips
1). Fan (exhaust fan, wall fan, the floor fan): installing a fan can keep the chicken house ventilated and blow away the heat and harmful gases of the chicken.
2). cooling pads fan: In a windowed or closed chicken house, the wet curtain longitudinal ventilation cooling system is the most effective cooling effect. The most common way to install the cooling pads in the chicken house is to install the wet curtain at one end of the chicken house. Exhaust fans are installed at the other end of the house.
Advantages: The effect of ventilation and heat dissipation is obvious, and the operation is simple. The staff only need to switch to start.
Disadvantages: Inadequate maintenance is easy to damage, power failure or failure to stop working. Uneven temperature the air inlet is cool, the end is hot, and the air humidity is high, which is not conducive to the epidemic prevention of the chicken house
2 Greening and cooling
1）. Tree planting: Plant tall trees around both sides of the chicken coop to avoid direct sunlight and play a shading role, allowing chickens to inhabit under the shade of the trees and reduce the breeding density.
2）. Plant grass: plant lawns around the chicken coop, uses the lawn to absorb heat and avoid sunlight reflection.
3）. Plant climbing vines: plant creepers, loofahs and other plants near the chicken house, so that the plants can climb the roof of the house to play a role of heat insulation and shade.
Advantages: low cost, no need for management, improvement of the enviroment of the chicken farm , trees and melons and fruits can become another economic source.
Disadvantages: The cooling effect can only be realized when the plants grow vigorously. When the typhoon storm comes, the branches will be cut off and the roots of the vines will damage the buildings of the chicken farm. The woods are easy to attract wild birds and bring risks to the disease prevention and control of the chicken shed.
3 building cooling
1）. Sunshade net: Put a sunshade net on the window of the chicken house to block direct sunlight from entering the house. You can also set up a sunshade net on the roof of the chicken house. The sunshade net must be higher than the roof of the chicken house by more than 50cm, and the chicken house will be shaded together to play a role in shading; or cover the roof of the chicken house with a layer of 10-15 cm thick straw or Straw, sprinkled with cold water and kept moist for a long time, can prevent a lot of heat from being drawn into the house.
2）. Lime-sprayed roof: Use white lime or white cement to paint the outer wall and roof of the chicken house in white to improve the reflection ability and heat loss rate of the outer surface, and reduce the transmission of solar heat to the chicken house.
3）. Insulation layer: The height of the chicken house 2 meters away from the chicken body is made of a white bubble film plastic of about 2 cm to make a ceiling, which can separate a large amount of hot air on the ceiling and reduce the temperature in the house.
4）. Pergola: Set up a pergola on the activity site closer to the chicken coop for shade, so that the chickens can inhabit and reduce the breeding density.
Advantages: Significantly reduce the temperature, ground temperature and light intensity, without affecting the environment inside the chicken house (lime spraying the roof is low cost and easy to operate).
Disadvantages: Manual installation of sunshade nets, pergolas and heat insulation layers requires investment costs, and sunshade nets and straws are easily damaged when it is windy and rainy, causing noise that affects the growth of broilers.
4 cool down with water
1）. Spray humidification: Use a high-pressure sprayer to spray the cold water just from the well with very fine water particles to increase the air humidity of the surrounding environment and achieve the purpose of cooling and humidifying.
2）. Sprinkle cold water on the ground: Sprinkle some cold water on
the ground of the chicken house to increase evaporation and heat dissipation, but it is required to open the doors and windows at the same time to increase the convection ventilation, otherwise the high humidity in the house will also aggravate the adverse effects of high temperature.
3）. Spray water on the roof of the chicken houses: use the pump to pump cold underground water to the roof of the chicken house, and the water will be sprinkled on the roof or the front and rear windows of the chicken house through the pipe through the holes or nozzles, without affecting the humidity in the chicken house. Be applicable.
4）. Chicken coop backflow water: uses a relatively thin plastic hose, hover and place it under or on the roof, and connect it with circulating water. The water flows continuously and slowly, and it is a good method not to waste water in water-deficient areas.
Advantages:cooling effect obviously, no mechanical drive, no noise interference, reducing stress on chickens.
Disadvantages: Water spray needs to be used in conjunction with fans, which wastes water resources, and the air humidity is high, which is not conducive to epidemic prevention in chicken houses.
5. Feeding and cooling
1）. Watermelon rind: chops the watermelon rind, feed each chicken about 50 grams a day, feed 3 times a day, feed alone at noon, mix feed in the morning and evening. You can also soak soybeans and gypsum powder at a ratio of 100 grams each and add 10 kilograms of water for 24 hours, and take the infusion as drinking water to feed chickens to improve the heat resistance of chickens.
2）. Feed pumpkins: You can feed them raw, cut the pumpkins into small pieces that chickens can eat, and let them eat. Feeding pumpkin can not only make laying hens survive the hot summer smoothly, but also promote laying hens to moult and increase egg production.
3）. Feed additives: Add appropriate an amount of vitamin C, E, K, B2 and biotin, bacitracin zinc and other additives to the chicken diet in hot summer; add appropriate baking soda, the bromide buffer, Huoxiang Zhengqi water, etc., Can effectively prevent or reduce the harm of high temperature to chickens.
Advantages: Increase feed intake to promote growth, improve the chicken performance, reduce heat stress.
Disadvantages: increase the cost of feeding, the effect is not easy to reflect
