At the turn of spring and summer, the weather is warm, and it is a season in which all kinds of poultry infectious diseases are susceptible to susceptibility. To do a good job in poultry house disinfection is an effective measure to prevent epidemics, reduce mortality, and improve the efficiency of poultry breeding. Among them, fumigation is the most commonly used method of disinfection in poultry houses. Fumigation is the use of formalin and potassium permanganate reaction, the generation of formaldehyde gas, formaldehyde gas diffuse throughout the poultry house, after a certain period of time to kill pathogenic microorganisms. The greatest advantage of fumigation is that the fumigating drugs can be evenly distributed to all corners of the poultry house. The disinfection is complete and thorough. It is especially suitable for the disinfection of contaminated air in poultry houses. When fowling and disinfection of poultry houses should pay attention to the following eight points: 1. The poultry house should be closed during disinfection. The higher the formaldehyde gas content, the better the disinfection effect. Before fumigation in a poultry house, check the airtightness of the poultry house. If there are gaps, seals such as plastic sheets, newspapers, or tapes should be used to prevent leakage and affect the disinfection effect. Second, Sheng containers must be resistant to corrosion. Both potassium permanganate and formalin are corrosive and react violently after mixing, releasing heat and generally lasting 10-30 minutes. Therefore, the container containing the drug should be large enough and resistant to corrosion. Third, with other disinfection methods. Because formaldehyde can only sterilize the performance of objects, therefore, the poultry house should be mechanically cleaned and spray-disinfected prior to fumigation. Fourth, temperature and humidity should be appropriate. The use of formalin 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 shenwen temperature is 26°C and the relative humidity is above 80%, the fumigation sterilization effect is best. Fifth, the concentration and proportion should be appropriate. The poultry house fumigation is generally suitable according to the amount of formalin 30 ml/m3, potassium permanganate 15 g/m3 and water 15 ml/m3. Six, disinfection method to ensure proper. Pour water into a ceramic vessel, add potassium permanganate, stir well, and add formalin. After entering formalin, the person left and closed the poultry house. Containers used for fumigation should be as close to the door as possible to allow the operator to evacuate quickly. The operator should avoid contact of formaldehyde with the skin. Seven, to ensure a certain disinfection time. The poultry house is fumigated and sterilized. Generally, it can be used after 24 hours. If it is not used urgently, it can be used after 2 weeks in order to ensure the disinfection effect. Eight, after ventilation, ventilation. After the poultry house is fumigated and sterilized, the formaldehyde smell in the poultry house is thick and irritating. Therefore, use more than 2 days of ventilation. If you need to use it, you can use ammonia to neutralize the formaldehyde, according to the space size with ammonium chloride 5g/m3, quicklime 10g/m3, 75°C hot water 10ml/m3, mixed into the container, Release ammonia gas. After 30 minutes, open the doors and windows of poultry houses and allow 30 to 60 minutes for ventilation.
