① Disinfectants can be treated with antitoxin or 111 fungicide at a ratio of 1:300-1:400; Disinfection King 1:300; It can also be disinfected with 1:300 100 poison killing spray.

② Generally, at least 1 liter is used per square meterdisinfectantAfter spraying disinfectant, close the doors and windows for 2-3 hours, then open the doors and windows for ventilation and wash the feeding trough with clean water. If the enclosure is made of soil, it should be sealed with new soil after disinfection and compacted with quicklime.

③ Formaldehyde fumigation disinfection: The specific method is to first place potassium permanganate in a container and place it in the disinfection area, and then add formalin. Due to the boiling and large amount of bubbles generated when the two drugs react, the container used should be deep and have a volume more than 10 times larger than the formaldehyde solution used. But do not add potassium permanganate to formalin during use. The drug concentration is 28 milliliters of formaldehyde solution, 14 grams of potassium permanganate, and 14 milliliters of water per cubic meter of space. Generally, it is required to seal and disinfect for 12-24 hours, and then open all doors and windows to release any remaining air.

④ It can also be sterilized with 0.2%~0.5% peracetic acid (2000ml per cubic meter) spray.

⑤ The disinfection of surrounding areas and roads can be carried out by spraying 10% bleach powder or 0.5% peracetic acid (200 milliliters per square meter). If the site is muddy, the surface soil should be excavated and sprinkled with bleach powder, mixed and deeply buried; Cement, asphalt fields, and roads can be disinfected by spraying with 2% to 3% caustic soda solution. Before use, they must be repeatedly rinsed (with a certain interval between them, rinsing every other day).

2. The disinfection of water used to be more complicated and expensive in the past when drinking water was boiled and disinfected with ultraviolet radiation. Currently available:

① Add disinfectants such as Kangdu Wei and Baidu Sha in proportion; Alternatively, 0.5-1 gram of chloramine can be added to every 1000 milliliters of drinking water, or 2-4 grams of bleaching powder containing 25% effective chlorine can be added.

② Wastewater can be treated with 6-10 grams of bleach powder per cubic meter of water (depending on the degree of water pollution), which can kill pathogens in the water after 6 hours; It can also be filtered and precipitated with alum before disinfection.

3. Disinfection of vehicle transportation tools.

① Transport vehicles carrying generally healthy livestock, poultry, and products, perform mechanical cleaning, and rinse with hot water at 60 ° C to 70 ° C.

② Vehicles and tools that have been used to transport infectious livestock and poultry (including viral and bacterial livestock) should be cleaned and disinfected with 1% to 2% hot caustic soda solution, and then mechanically disinfected and cleaned the next day. If the pollution is severe and the condition is severe, effective disinfection and cleaning should be repeated.

4. Wear work clothes and hats that are regularly disinfected; When there is an epidemic, it is even more important to pay attention to the cleaning and disinfection of work clothes and hats (changing them daily if necessary). They can be disinfected by sunlight, boiled or fumigated with formalin for 20 minutes. Work clothes are not allowed to be worn out of the production area, whether during normal times or during epidemics. Unconditionally, the above disinfection requirements should also be followed for frequent changing, laundry, and pants, and disinfection should be carried out.

5. Disinfect the staff by repeatedly wiping their hands with disinfectant soap; During the epidemic, after washing with medication soap, immerse in a 1:1000 solution of chlorhexidine for 3-5 minutes, rinse with water, and then dry.

It is worth noting that some breeders, especially novice breeders, are not yet fully aware of the importance of disinfection; Some people may verbally emphasize the need to strengthen disinfection, but in reality, they only do disinfection of the enclosure or environment, neglecting the disinfection of hands, feet, clothes, tools, and other aspects. This often leads to the dilemma of raising a batch, causing a continuous outbreak of diseases. Therefore, its harmfulness cannot be underestimated, and it must be highly concerned by breeders and implemented in production, strictly controlling the disinfection and hygiene work in each link.
