First, the impact of high temperature and high humidity In the case of high temperature and high humidity, the difference between the water vapor pressure on the surface of the pig body and the water vapor pressure in the air is reduced, so that the heat dissipation of the pig body is reduced, and the heat dissipation of the pig body is more difficult, thereby aggravating the heat stress of the pig. At 42 ° C high temperature and dry climate, the sow will not die hot; while the temperature is 37 ° C but the humidity is high, the sow will die hot.
High gas humidity is conducive to the reproduction of various pathogenic microorganisms and parasites, which increases the incidence of pigs and exacerbates the disease; pigs are prone to skin diseases such as phlegm and eczema, and are also prone to piglet paratyphoid, piglet diarrhea, swine fever, pig erysipelas The prevalence of infectious diseases.
Second, moisture protection measures
Do not flush the floor with water
Even if the floor must be flushed, it must be done in a well-ventilated, sunny weather to dry the air and the floor as quickly as possible.
Maintain ventilation inside the house
Increase the window area: increase the ventilation inside and outside the house;
Open the floor window: the ventilation effect is more obvious than the ventilation of the upper window, because the wind passing through the ground window is directly blown to the ground, and it is easier to evaporate the water;
Using a fan: The fan can enhance the air flow. This method works very well when used in an empty house. When we were unable to dry in the nursery, we used a large fan to keep up the air and quickly dry the nursery.
Take moisture-absorbing materials such as quicklime
Some people will say that quicklime will heat up, can improve the temperature inside the house, and should not be used in summer pig houses; the use of quicklime has more advantages than disadvantages. First, the calorie produced by calorie is very small, and the temperature inside the house is not significantly improved. Second, after the air is dried, The sow sucks on the dry air, which is more conducive to the loss of heat in the body. That is, the high temperature and low humidity we have said before will not heat the sow, but the temperature is not so high, but the humidity will be high, but the sow will die.
