Several summer cooling measures for pig farms
2019-05-31
In the hot summer sun, there is inevitably a high temperature and sultry situation in the pig house of the pig farm. In order to create a good growth environment for the pig, it is necessary to cool the pig house. Here are some common cooling conditions for the summer pig farm. Measures for your reference. First, planting trees, shading and cooling: planting high-speed fast-growing broad-leaved trees, melon vines or shade nets near the pig house in the pig farm to cool the fast-growing poplar, loofah, pumpkin, etc. around the pig farm and pig house, which can reduce solar radiation. To cool down and improve the air quality, shade nets can also be used to shade pig farms. Second, use the spray cooling system: install a spray cooling system in the pig house. This system consists of a negative pressure fan, a high pressure water pipe, an atomizing nozzle, a small water pump, a timer, a water storage tank or a small reservoir, suitable for pregnancy. The sows are cooled. Third, the use of drip cooling system: the installation of a drip cooling system consisting of a negative pressure fan, a normal pressure water pipe, a drip device and a control valve, suitable for the cooling of the sow and fattening pigs in the delivery room. For sows in the delivery room, water droplets will be placed on the neck and shoulders of the sow, and the pigs will dissipate heat by evaporation. In the fattening house, when dripping water, the pigs will play around the dripping water, the local temperature in the pig pens will gradually drop, and the heat stress state of the pigs will gradually ease and rest quietly. The fattening house generally does not require a negative pressure fan. Fourth, the use of cooling curtain cooling fan cooling system: the installation of negative pressure fan, small water pump, cold water closed circuit and wet curtain composed of negative pressure fan plus cooling curtain system, generally the negative pressure fan, wet curtain respectively installed in The gables on the two ends of the pig house or the front and rear walls, the hot air outside the wet curtain is converted into cool air into the pig house through the wet curtain with cold water circulation. After a period of time, the wet curtain is closed, and after the temperature in the pig house rises, the other is opened. The fan at one end draws hot air to lower the temperature inside the house. Suitable for cooling in boar houses, pregnancy rooms and delivery rooms. Fifth, the use of cooling fan cooling system: cooling system consisting of air cooler, air duct, small water pump, reservoir or small water well, inlet pipe, negative pressure fan, suitable for breeding boar house, empty house, pregnancy The temperature of the sow house and the delivery room is basically the same as that of the wet curtain. Today's Xiafutian is a long standby for 40 days, so it is very important for us farmers to do a good job of cooling down. The above five articles are for your reference and do a good job of protection.
