To make full use of the favorable conditions for the sale of livestock and poultry before the Spring Festival, it is necessary to strictly disinfect and kill pathogenic microorganisms and ensure the safe production of livestock and poultry prior to restocking. Disinfection objects include: livestock and poultry manure, roads, grounds, houses, utensils, feed grains, water basins, and transportation vehicles.
1. Disinfection of housing: excrement, litter (grass) and other cleaning materials, compaction and fermentation (preferably in a dry place far away from the site, excavation special fermentation pit seal disinfection); floors, walls, doors, windows, appliances, etc. According to the type of infectious disease, choose a suitable disinfectant for thorough spraying and cleaning.
1 Disinfectant can be used for antiviral drug or 111 sterilizing agent 1: 300 to 1: 400; disinfecting the king 1: 300; also can be used 1: 300 germ poisoning spray disinfection.
2 Generally, at least about 1 liter of disinfectant is used per square meter. After disinfectant is sprayed, close the doors and windows for 2 to 3 hours. Then open the windows and ventilate and then wash the feeder trough with clean water. If it is a soil shed, it should be used after disinfection. Washers and lime compaction.
3 formalin fumigation: The specific approach is to put potassium permanganate in the container, placed in a sterile place, and then join the formalin. Since the two drugs react to boil and generate a large amount of bubbles, the containers used are deeper and the volumes are 10 times greater than the formaldehyde solution used. However, do not add potassium permanganate to formalin. The drug concentration was 28 ml of formaldehyde solution per square meter of space, 14 grams of potassium permanganate, and 14 ml of water. It is generally required to seal and sterilize for 12 to 24 hours, and then open the door and window to drain the remaining gas.
4 It can also be spray sterilized with 0.2% to 0.5% peracetic acid (2,000 ml/m3).
5 Disinfection of surrounding sites and roads can be sprayed with 10% bleach or 0.5% peracetic acid (200 ml/m2). If the soil site should be excavated surface bleaching powder, mixed, buried deep; cement, asphalt sites, roads can use 2% to 3% caustic soda liquid disinfection, must be washed repeatedly before use (there should be a certain interval between the time, the best Rinse every other day).
2, water disinfection, drinking water in the past using boiling, ultraviolet radiation disinfection method is more troublesome, and the cost is also large. Available today:
1 anti-drug Wei, 100 poisoning, etc. can be added according to the proportion of disinfection; can also be used per 1,000 ml of water plus chloramine 0.5 to 1 gram, or add 25% of available chlorine bleach 2 to 4 grams.
2 Sewage can add 6-10 grams of bleaching powder per cubic meter of water (depending on the level of water pollution increase or decrease), after 6 hours can kill pathogens in the water; can also be filtered after the addition of gelatin precipitation and disinfection.
3, disinfection of vehicle tools.
1 Carriage tools for general healthy livestock and poultry and products are mechanically removed and rinsed with hot water at 60°C to 70°C.
(2) Vehicles, tools, and 1% to 2% hot caustic soda solution are to be used for cleaning and disinfection of infected livestock and poultry (including viruses and bacterial livestock), and then mechanically disinfected and cleaned on the next day. If the pollution is serious and the disease is severe, effective disinfection and cleaning should be repeated.
4, wear uniforms and caps, regular disinfection; when there is an epidemic should pay attention to the work clothes and caps cleaning and disinfection work (if necessary, every day replacement) can usually be used to sterilize sunlight, can also be sterilized by boiling or formalin fumigation 20 minute. Whether it is usual or epidemic, uniforms are not allowed to pass out of the production area. Unconditional should also refer to the above disinfection requirements, frequently changing, washing, pants, and disinfection.
5, the staff disinfect the application of disinfectant soap rub hands several times to disinfect; epidemic should be washed after the use of soap, immersed in a 1:1000 solution of benzalkonium bromide 3 to 5 minutes, dry water rinse.
It is worth noting that some breeders, especially the young ones, are not very aware of the importance of disinfection; some verbally have to strengthen the disinfection, but in fact have only done the disinfection of the housing or the environment, and ignored the hand. Disinfection links such as feet, clothing, tools, etc., often lead to the maintenance of a batch of epidemics and a series of continuous epidemics. Therefore, we must not underestimate its harmfulness. We must heighten the attention of breeders and put them into practice in production. We must strictly adhere to all aspects of disinfection and sanitation work.
