Regarding the method of disinfection of pig farms, it is enough for pig farmers to read this article.
When it comes to disinfection of pig farms, many farmers do not pay much attention to it. In fact, disinfecting pig farms is one of the most important tasks for pig farmers. If disinfection is done well, many pig diseases can be killed in the cradle. Save a lot of drug costs and improve the breeding efficiency of the farm.
Disinfection is an important technical measure to kill or reduce pathogens in the production environment using physical, chemical or biological means. Disinfection, as an important way to cut off the route of transmission, is considered by pig farmers to be the simplest and most effective way to prevent diseases on the farm. In actual clinical practice, although everyone knows that disinfection is important, there are very few pig farms where disinfection can be implemented. Recently, the swine fever epidemic in Africa is serious. In the absence of an effective vaccine, disinfection has become the most effective way to prevent and control. Today, pig farmers are introduced from the various aspects of disinfection to the precautions of disinfection.
Disinfection classification
1, daily disinfection. Various disinfection work in production areas and pigs according to the needs of production. Including regular disinfection of pens, roads and pigs, disinfection of pre-clinical delivery rooms, laboratories, piglet tailing, disinfection of wounds after castration, disinfection of personnel and vehicles entering the production area.
2. Disinfect at any time. It means that when some pigs in the herd have half of the blood blight or sudden death, they need to immediately strengthen the disinfection of the house.

Disinfection method
1. Physical law. These include flushing with high pressure water, ventilation in the pig house, high temperature, drying and lighting.
2. Chemical law. The most common method of disinfection refers to the use of chemical disinfectants to kill pathogens in the environment.
3. Biology. It refers specifically to the production of feces, sewage, garbage and other methods of fermentation to generate heat to kill the pathogens.
Disinfection facilities and equipment
The disinfection facilities of the pig farm include a disinfection tank at the gate of the pig farm and the production area, a small disinfection tank at the entrance of the pig house, a disinfection passage for personnel entering and leaving the production area, and a stacking fermentation field for the sewage treatment. a, large disinfection tank. The specifications are generally the width and the width of the gate, the length is 1.5 times the maximum wheel circumference, and the depth is deeper than 10 cm. b. Small disinfection tank. Built at the entrance of the pig house, the width is the same as the width of the pig house, and the depth is about 10 cm.
The disinfection equipment includes a high pressure cleaner, a flame sterilizer, a solid-liquid separator, various sprayers, and the like. a, sprayer. Used to spray a variety of disinfectants. b, flame sterilizer. Used for disinfecting the ground and equipment of pig houses. c, UV lamp. For the sterilization of any item, it is generally set up at the gate.
Chemical disinfectant. Commonly used disinfectants are alkalis (such as caustic soda, quicklime), phenols (bacteria poisoning, Warwick II), quaternary ammonium salts (Xinjieer, Baidu), halogens (disinfection, povidone iodine), etc. .
Disinfection procedure
When the pigs in the pig house are transferred away, the disinfection process should be started, cleaning - high pressure water washing - spraying disinfectant - cleaning - fumigation - drying - spraying disinfectant - into the pig. The above procedures are not static, and pig farmers can make decisions based on the occurrence of the disease on their own farms and the disinfection equipment in the farm.
1. Disinfection of the disinfector. Change clothes or work shoes, and replace the clothes and shoes that can be disinfected by ultraviolet rays or the like in the locker room.
2, the door disinfection vehicle disinfection. The surface of the object and the surface of the object to be carried shall be disinfected by spraying a disinfectant outside the gate, and enter the inside of the pig farm through the disinfection tank.
3. Disinfection of substances. Under normal circumstances, the disinfectant can be used after spraying. In case of epidemic situation, it is recommended to use it after fumigation.
4. Disinfection in the production area of ​​the city. The main roads in the production area are required to be cleaned daily, and disinfected with disinfectant 1-2 times a week. When there is an epidemic, the disinfection frequency is increased.
5, the pig station disinfection. The pig station and the pig-feeding channel are required to be cleaned and sprayed with disinfectant immediately after each use.
Conventional disinfection
1. Sterilization of sick and dead pigs after necropsy. After the necropsy of the dead pig, the corpse of the pig should be cleaned and disinfected with a disinfectant. The disinfectant is used to disinfect the hands and shoes.
2. Disinfection of work clothes. Work clothes should be cleaned regularly and placed in the sun for disinfection. If it is exposed to sick pigs, it is recommended that the work clothes and work shoes should be disinfected in the disinfectant for better disinfection.
3. Pig body disinfection. The pig body surface is spray disinfected regularly with a disinfectant. The piglets are sterilized when they are broken and castrated.
4. Disinfection of medical devices. Syringes and needles should be boiled and disinfected. The thermometer should be wiped with alcohol cotton and then placed in a disinfectant.
