How to Control the Humidity of a Farm in the Rainy Season

Humidity causes pigs to be mainly affected by temperature. For example, pigs in summer are susceptible to diarrhoea, often because the pig house is damp. This dampness is not only damp in the air, but more serious is the dampness of the ground and the humidity in the incubator. When the ground is wet, in the drying process, the heat in the air needs to be absorbed to reduce the ambient temperature. The first thing to change is the 25 cm to 30 cm net bed from the ground. This is where the pigs lie and move. . If the incubator is wet, it directly affects the pigs that are in contact with it. In this way, it seems that the temperature in the air is not low, but the effective temperature felt by the piglet is insufficient, and due to the temperature discomfort, the sub-pig's digestive function is reduced, the digestive tract resistance is weakened, and the disease is caused.

If the pig enters the wet environment from a dry environment, it will also show obvious incompatibility. This phenomenon often occurs in the swine's transition process. Because most of them are now in the all-in, all-out feeding mode, every time the pigs go away, they must undergo thorough cleansing and disinfection. If the herd turnover is tight, pigs often have to be transferred before they are dry, despite the dry bed. However, the ground and the walls are still not dry; when the temperature is not high, the pigs will be cold, and when the temperature is high, the humidity will be too high. Together with other stress during the transfer, the possibility of herd development is very high. .

The production of moisture is water. The summer delivery room is humid. It is often related to sow playing with water when it is hot, and it is also related to the fact that the breeder is flushing the floor for excessive cooling. There has been no better way to solve the high temperature problem, so the delivery room has been in a humid environment. Humidity in winter maternity units is often due to tight closure, water vapor in the house cannot be discharged, and the cold walls and roofs once again form a water flow to the ground. This way, the house is kept in a wet state. This phenomenon is cold. Regions often appear.

Empty pig houses are wet due to rinsing and disinfection. Many people attach importance to disinfection, and sterilize them again and again after rinsing, so that the pig house cannot be dried and the pig can only enter the wet environment.

The solution to wetness can be considered from the following aspects.

Increase ventilation. Ventilation can vent water vapor inside the house, but how to ventilate, according to the conditions of different piggery to take corresponding measures. One is to raise the delivery bed so that the pigs stay away from the wet ground. The second is to increase the window area and increase the ventilation outside the house. The third is to open the ground window, because the wind through the window directly to the ground, it is easier to make the water evaporate. The fourth is the use of a fan. The fan can enhance the flow of air. The effect is very good when used in an empty space.

Control water use. In moisture-sensitive pig houses (such as the delivery room and pre-care stage), water should be controlled, and in particular, water should be reduced as much as possible.

Lay lime on the floor. Laying lime in the house floor can make use of moisture absorption characteristics of quicklime to make local air dry.

Bake dry planks. In situations where the home environment is not easy to control, simply giving local pigs a small microclimate also has a good effect. The method is to often dry the wood pallets laid for the pigs on a stove or give a pig shop a few days before the birth. Dry cloth or carpet, so that the pig to avoid lying on a wet plank, also has a certain effect on the prevention of diarrhea in piglets.

Low temperature water pipe. The low-temperature water pipe also has the function of absorbing moisture. If the water pipe below 20°C passes through a damp pig house, the water vapor inside the house will become water drops and flow down from the water pipe; if there are more water pipes in the house, drainage facilities will be set up at the same time. It will also reduce the humidity inside the house.

There are many methods of dehumidification. Shearing stoves can be used for dehumidification, air-conditioning can be used for dehumidification, and increased ventilation can also reduce humidity. Controlling the frequency of flushing the ground and preventing water leakage can also reduce the humidity. Farms can use their own The actual situation is used flexibly.
