Modern farming management emphasizes adopting all-in and all-out feeding management methods. After a feeding cycle, there are different levels of pathogen contamination in the stables, which must be thoroughly disinfected to create a clean and hygienic environment for the next feeding cycle. The process is as follows:
Because different pathogens have different susceptibility to different disinfectants, it is recommended to use different disinfectants for 2 to 3 times of disinfection. The first disinfection can be done with alkaline disinfectants, 1%-2% hot sodium hydroxide can be spray-disinfected, l0% lime milk can be used to paint walls, coils and floors; the second disinfection can use phenols, surfactants or Oxidizers (such as peracetic acid) are spray sterilized. In order to improve the disinfection effect, spray pressure should be 3.4 ~ 67.5kgf/cm2, liquid medicine dosage is 1m2 with 0.25 ~ 0.4L of diluted liquid, when spray disinfection, according to the order of disinfection of the livestock quarters, then the front part, then the front, the top of the wall, Ground again; the third disinfection can be formalized and fumigated. In the oxidation method, high-temperature evaporation occurs when formalin (42 ml/m3) and potassium permanganate (21 g/m3) are mixed. For the heating method, 25 ml/m3 of formalin was used, and the same amount of water was heated and evaporated. There should be an interval between disinfections. After the last disinfection, it should be washed, dried, and then disinfected again.
Disinfectants for livestock and poultry disinfection should have the characteristics of broad spectrum, high efficiency, low toxicity, low corrosion, and strong adhesion. With poultry disinfection, in the high temperature brooding and cold winter season should pay attention to the dilution of the water temperature and insulation measures, disinfectants preferably rotation every month; chickens inoculated attenuated vaccine before and after 2d, a total of 5d stop spraying disinfection.
