Heat prevention and cooling measures of pig farms in summer

With the gradual rise of the temperature, the high temperature and humidity environment pig farm in summer is a strict test, which can easily cause stress reaction and heatstroke of pigs, lead to disease and disease in summer, threaten healthy pig farms and bring huge economic losses to pig farms. So how to cool down the pig farm to prevent heat in summer? Let's take a look.

1. Heat insulation of pig house

Generally, pig houses are trimmed with asbestos tiles or earth bricks, and the thermal insulation is poor, while most of the pigs raised in rural areas are open pig houses, and the temperature is even more difficult to control. Therefore, before the high temperature comes, there is no thermal insulation such as straw and straw at the top of the pigsty, while the open-air pigsty can build an Arbor and plant some vines next to the walls of the barn to improve thermal insulation. You can also plant trees around the enclosure to improve the microclimate, or smear lime milk on the outer walls of the pigsty to reduce sunlight by reflecting the original light.

2. Ventilation and cooling

One of the important measures for cooling the ventilated pig house is to open the doors and windows in the morning and evening when the weather is cool and let the air form convection, but when the temperature in the house is lower than the external environment, it is not suitable to carry out ventilation and cooling. To form a suitable air flow to promote the heat dissipation of pigs. In addition to natural ventilation and cooling, mechanical cooling can also be carried out in the piggery according to the exhaust fan, or water curtain can be installed to avoid installing the exhaust fan. The exhaust air is discharged from the water curtain for air intake, so that the cold air enters the room and lowers the temperature.

3. Spray water

Spray water in the form of fog, the fog will continue to evaporate in the process of falling, absorb heat in the air, reduce air humidity, such a cooling method is also good. You can also pour water directly on the pig, which will accelerate the heat dissipation of the pig and play an important role in cooling, without lowering the air.

4. Strengthen feeding

Pigs dissipate heat slowly in hot summer, so the breeding density should be reduced appropriately so that pigs can dissipate heat. At the same time, anti-stress and electrolyte are added to feed, and electrolytes are added to drinking water to reduce heat stress reaction. In the feed can add an appropriate amount of heat-clearing and detoxification, Sheng Jin to quench thirst drugs, such as plantain water fried mixture to take, or mung bean porridge after cold feeding, feeding fresh watermelon peel are good heat prevention effect.
