Disinfection is one of the important measures for the comprehensive prevention of animal diseases. Standardized farms must establish a strict disinfection system. Since 2008, we have found many problems in the disinfection work in the review of animal epidemic prevention conditions on scale farms: Disinfection layout is unreasonable In the on-site review of the 260 large-scale pig farms and chicken farms, only 9 large-scale farms have disinfecting pools and 16 fields have disinfecting and disinfecting rooms. However, their settings are not standardized, and the gates on the field are not Disinfecting the pool, but only at the entrance of the production area, changing the disinfection room is located in the entrance area, and there is no disinfection pool or disinfecting pad at the door of each barn. Only two pig farms have special pig sales stations. Insufficient disinfection equipment Only 14 farms set up UV lamps in the disinfection room. The rest was only small sprayers. Only 36 fields had washing equipment and only 5 autoclaves. The use of unreasonable disinfection of the pool does not meet the standards, some shallow or too short, some can not hold water, and some do not put disinfectant. People enter the UV disinfection room without stopping, and they will not achieve disinfection. Disinfection equipment is in name only. Unreasonable process Most pig farms have no empty period and can not completely sterilize the pig house. This is also the main reason that the old farms are difficult to keep disease. The disinfection method is inaccurate and neglects the mechanical cleaning work before chemical disinfection. Disinfected sites have faeces, feed residues, sewage, etc. that hinder the use of disinfectant drugs. Disinfectants are consumed by a large amount of organic matter, which severely reduces the effect on pathogenic microorganisms. Some piled up in the disinfection pool or around the barn thick lime, lime actually no disinfection. Quicklime is calcium oxide, and it only produces hydrated lime with hydroxide ions when it encounters water. Some use slaked lime that has been left for a long time, but it has absorbed carbon dioxide from the air and becomes calcium carbonate without hydroxide ions, which has completely lost its sterilizing effect. Improper use of disinfecting drugs Some long-term use of one or two kinds of disinfecting drugs for disinfection, occasional replacement, resulting in pathogenic bacteria resistance, affecting the disinfection effect; some are still using traditional quaternary ammonium salts, phenols, ethanol, etc. The disinfectant that does not have a significant effect on certain viruses can be arbitrarily increased or decreased when disinfecting liquids are prepared. The stronger the disinfectant is, the better the irritant effect is, and the concentration of the disinfectant is arbitrarily increased, and the strong irritating odor is aggravated. The condition of livestock and poultry. Some disinfectants have been stored for a long time, and even if the two drugs are mixed or used in the same place at the same time, such unscientific and irregular methods of preparation and use greatly reduce the effect of disinfecting the drugs. Management is lax Many farms have not established disinfection procedures, or some have established disinfection procedures, but they have not been implemented in every relevant person. Disinfection is arbitrarily large and does not achieve the desired results. Some only attach importance to the disinfection of the barn and ignore the disinfection of the environment and sports grounds, neglecting the disinfection of personnel and disinfecting work clothes and caps. Most of the farms do not treat the excrement harmlessly, and randomly deposit excrement, dirt, residues, etc. on the site or around the site to cause environmental pollution. Visits to the government and business departments are hindered by sentiment, and they are allowed to enter the production area without disinfection. In particular, the purchasers and the acquisition of transport vehicles are not strictly disinfected into the production area, and even the purchasers can go to catch pigs and catch chickens. For the disinfection problems existing in the above farms, the following countermeasures must be taken to strengthen disinfection. According to the provisions of the “Measures for the Examination of Animal Epidemic Prevention Measures†of the Ministry of Agriculture, the disinfecting layout and equipment configuration should be well done. A disinfection tank with a width of 4 meters and a depth of 0.3 meters is set at the entrance and exit of the site; dressing and disinfection rooms are set at the entrance of the production area; disinfection cistern or disinfecting pad is set at the entrance of each breeding shed; and clean roads and pollution are produced in the production area. Roads are divided; disinfection equipment is installed at the entrance of the field area; suitable materials are used for the ground and walls of the housing for cleaning and disinfection. Sterilization should be standardized and institutionalized to establish a strict disinfection system and disinfection procedures. Adhere to all aspects of disinfection work, including the transport of foreign vehicles, personnel disinfection and disinfection of the surrounding venues. According to the different phases of production and feeding, different parts, different links, different objects and different purposes, different disinfection methods are adopted to achieve the best disinfection effect. Putting an end to purchasers and acquiring vehicles. Establish emptying period and thoroughly disinfect. The selection of suitable disinfectant generally has good bactericidal performance, rapid action, exact effect, wide bactericidal spectrum, stable nature, less corrosiveness, easy dissolution in water, and convenient disinfectant with suitable price. The choice of disinfectant should not only consider the killing effect of pathogenic microorganisms, but also consider the safety of humans and animals, such as sodium hydroxide solution, which has a very good killing effect on viruses, bacteria, spores, and fungi. Drugs that have a strong corrosive effect on humans and animals can be used only when they are empty. Spray disinfection of drugs should use strong bactericidal, pungent drugs. Lime is formulated to disinfect 20% lime milk and is mainly used for disinfection of walls and the environment. Change the type of disinfectant frequently. Specification disinfection operation method First of all, before the disinfection, the environment and the barracks should be cleaned thoroughly. For the tall barn houses, a large amount of disinfectant can be sprayed from the top to the bottom. After cleaning the debris and dirt, fully flush it with a high pressure water gun and wait for the drying. Afterwards, spray another disinfection agent once and clean it with water afterwards. If necessary, sterilize it again. Working clothes and hats should be sterilized or autoclaved. SICHUAN UNIWELL BIOTECHNOLOGY CO.,LTD. , https://www.uniwellbio.com
