In the spring, poultry are most susceptible to various diseases, especially broilers. Therefore, the disinfection of broiler houses is an effective measure to prevent the occurrence of various diseases. Spring broiler house disinfection, fumigation is a commonly used method. Fumigation is the use of formalin and potassium permanganate reaction to produce formaldehyde gas, after a certain period of time to kill pathogenic microorganisms. Its greatest advantage is that the fumigating drugs can be evenly distributed to all corners of the poultry house, and the disinfection is thorough and complete, which is particularly suitable for the disinfection of contaminated air in poultry houses. When the poultry house is sterilized, the poultry house must be inspected for airtightness before fumigation. If there are gaps, seals such as plastic sheets, newspapers, or tapes should be used. Sheng drug containers to be corrosion-resistant potassium permanganate and formalin are corrosive, violent reaction after mixing, release heat, generally sustainable for 10 minutes to 30 minutes. Therefore, the container containing the drug should be large enough and resistant to corrosion. In combination with other sterilization methods, the formaldehyde produced by the reaction of formalin and potassium permanganate can only sterilize the surface of the object. Therefore, the poultry house should be mechanically decontaminated and spray-disinfected prior to fumigation. Temperature and humidity should be suitable for formalin fumigation and potassium permanganate reaction for poultry fumigation, the general temperature should not be less than 18 °C, relative humidity of 60% to 80% is good, not less than 60%. When the temperature is 26°C and the relative humidity is more than 80%, the fumigation sterilization effect is best. Concentration and proportion should be appropriate The poultry house fumigation and disinfection is generally based on formalin 30 ml per cubic meter, potassium permanganate 15 g per cubic meter and 15 ml of water per cubic meter calculated amount is appropriate.
