Disinfection is one of the three major technical measures for animal epidemic prevention, and it pays equal attention to immunization and epidemic prevention. It is an important technical measure for large-scale chicken production. Let’s take a look at the broiler cage equipment manufacturers below!
In rural areas, due to the traditional thinking of emphasizing immunotherapy but not disinfection, effective disease prevention and control often fail. Disinfecting chicken farms is a good way to prevent and control the occurrence, spread and spread of infectious diseases. Only by formulating and adopting a complete set of strict disinfection measures can the pathogens spreading on the environment, the surface of the chicken body and the tools be effectively eliminated, and the path of infection can be cut off, thereby promoting the healthy growth of the chicken. The disinfection method is now introduced as follows.
1. Disinfection of the chicken house
Sweeping and cleaning
After the chicken is sold or transferred out, the chicken manure, litter, etc. should be cleaned up, the chicken house should be thoroughly cleaned and washed, and the sink and other utensils should be cleaned. The walls should be washed with lime water, and the cleaning and washing should be carefully and carefully. It is carried out in a certain order, usually sweeping first, then washing, the ceiling first, the wall then the ground, from the far end of the barn to the door, indoors and then the environment, leaving no dead corners, after careful and thorough cleaning and cleaning, not only can 80% be removed~ 90% of pathogens, and can greatly reduce the amount of feces and other organic matter, which is conducive to the role of chemical disinfectants.
The disinfection of empty houses generally requires the use of 2 to 3 different types of disinfectants for 2 to 3 times. Only one disinfection or only one disinfectant can not achieve the purpose of thorough disinfection, because different pathogens have different sensitivities to different disinfectants. Alkaline disinfectant can be used for the first disinfection, such as 1% to 4% caustic soda or 10% lime milk to paint the ground and walls, and the appropriate concentration of caustic soda solution can also be used for spray disinfection; for the second time, phenols or oxidants (peroxyacetic acid) can be used. ) Perform spray disinfection; use formaldehyde fumigation for the third time. It can be fumigated by heating method or oxidation method. When using oxidation method, calculate the disinfection volume first. Use 42 mL formalin and 21 g potassium permanganate for 1 m3. For oxidation disinfection, close doors and windows, heat to 20 ℃, and relative humidity 70% Above, the effect is 7-24 hours.
