Pig farm hygiene management and disinfection
The cleanliness of pig houses and pig farms has a lot to do with pig health. Pig farms and pig houses must not only be clean, but also should be regularly disinfected to completely eliminate the pathogens stored in the culture environment, reduce the occurrence of diseases and ensure the health of the pigs.
Hygiene management and disinfection measures:
1. Sanitary management and disinfection of farms: In order to prevent the threat of pigs and pathogens brought by feeding and management personnel and vehicles, a wide and deep disinfecting pool and hand-washing disinfection basin should be set at the gate of the pig farm. Vehicles that go out and go out must be sterilized before entering the market. For demanding breeding farms, whether it is outsiders or staff, if necessary, shower baths, sterilized clothes and shoes should be replaced to enter the production area. Each building is equipped with a small disinfection tank (pool), which can be accessed after trampling. Foreign vehicles that have to enter the farm must not only pass through the disinfection pool, but must fully spray the vehicle before entering the site. There should be a dressing room outside the pig house. In order to enter the piggery, the coat must be replaced with work clothes and work shoes, and the fingers and shoes must be disinfected. There is a UV lamp in the locker room to disinfect the work clothes and shoes. The work clothes should be washed regularly and sun-disinfected.
2. Hygiene Management and Disinfection of Personnel: Veterinarians are often exposed to the disease. Many pathogens are transmitted by veterinarians. Therefore, veterinarians should sterilize their hands and shoes when they enter the pig house or treat the disease when they leave the pig house. Contaminated clothing should also be disinfected. Clothes and shoes should be washed and disinfected regularly and kept clean. The syringe is boiled and autoclaved, and a pig is given an injection needle. If it is used to treat infectious diseases, the used syringe must not be used again without being sterilized. When the liquid is drawn, the clean application of the liquid is not used. Sterilize the needle. Workers are required to undergo regular medical examinations every year and find that diseases involving communicable diseases such as tuberculosis and brucellosis should be removed from the production area for treatment. Personal items must not be brought into the premises, and personal and household clothing must not be washed in the cleaning room. In the case of artificial insemination, confinement, etc., in full contact with the pig body, it is necessary to wear sterile gloves and masks. When suffering from acute upper respiratory infections such as colds, tonsillitis, etc., patients should be transferred from the production area to arrange work. Staff returning from the field and returning to work should work in the administrative area for 2 days. After purification, they will enter the production area. If they come into contact with animals, they should be purified in the administrative area for 6 days and then enter the farm after showering and changing clothes.
3, pig health management and disinfection: During the production of pigs to ensure regular water showers, brush clean, especially breeding pigs, should pay attention to the armpits, stocks, forks and toes and other parts of the cleaning, and then spray with disinfectant Transferred to the matching sow, the need to use the body surface of the net twice in intervals of 10 consecutive spray to kill adults, eggs and larvae; before mating, should cut off the long hair near the boar foreskin, wash swab The hindquarters of the sows, especially around the perineum, to prevent reproductive diseases and other diseases caused by pathogenic tract infection during mating; to sterilize the breast area before delivery, wash the genitals and hindquarters with disinfectant after delivery, clean the placenta and disinfect delivery room. If the weather is cold, scrub the body and apply warm water, and pay attention to the cold. In addition, in the process of cutting the teeth, cutting tails, and injecting iron, the piglets must be disinfected in the apparatus and the surgical department.
4. Hygienic management and disinfection of pig houses: Pighouses should be frequently excreted, once a day, and kept dry. In summer, the number of excrement can be increased. After cleaning, rinse with water. However, it is not advisable to wash the water in the winter or the branch house and the nursery, and it should be kept dry. The manure can be removed by the lime powder and washed with a high-pressure water gun. The manger and the sink should also be kept clean. Before each feeding, the material left in the tank should be removed. Because the remaining material is easily corrupted, it should be washed clean. The sink should also be cleaned once a day. If it is a nipple drinker, it will be convenient and hygienic. After thorough cleaning, it should be disinfected on a regular basis. The summer barn should be fully disinfected at least twice a month and once in winter. Feeding tanks, walls, etc. should be regularly sterilized, but the feed tanks and sinks should be flushed with water once to remove the disinfectant. The vacated pig houses should be cleaned and sterilized before entering the pigs. Generally, they can be processed in the following order.
Pighouse emptying → remove manure → high pressure water gun washing → 2% → 3% alkaline water disinfection → 3-6 hours with hard brush scrub the ground, walls and dead ends → thoroughly washed → dry for a few days → formalin fumigation or flame disinfection → Let it dry for a few days → Disinfectant Disinfectant No. 5 Disinfectant → Let it dry for a few days before entering the pig.
The dead carcasses and contaminated feces should be detoxified at the designated locations.
