The disinfectants commonly used in pig farms include sodium hydroxide, lime, Saicoxin, Nongfu, acetic acid, and bleaching powder. Different disinfectants use different environments and methods.
1, sodium hydroxide (also known as caustic soda, caustic soda or fire alkali): alkaline disinfectants, crude products are white opaque solid, there are pieces, tablets, tablets, rods and other shapes; known as the solution state of liquid caustic soda, mainly used Disinfection on site, barracks, etc. A 2-4% solution kills viruses and reproductive bacteria. A 30% solution kills the spores in 10 minutes. A 4% solution kills the spores in 45 minutes. If 10% salt is added, it will increase sporulation capacity. In practice, a 2% solution is often used for disinfection. After sterilizing for 1-2 hours, rinse with clean water.
2, lime (lime): Alkaline disinfectant, the main component is CaO, water is served as calcium hydroxide, commonly known as slaked lime or slaked lime, with strong alkaline, but water-soluble, dissociated out of hydroxide ions is not much, Disinfection is not strong. 1% lime water kills normal propagation bacteria for hours, and 3% lime water kills Salmonella for 1 hour, which is not effective for spores and TB bacteria. Its greatest feature is its low cost and easy availability. In practice, 20 parts of lime are added to 100 parts of milk made of lime to be used for painting walls, sheds, floors, etc., or directly added to the liquid to be sterilized, or sprinkled on wet ground and septic tanks and Sewers and other disinfection.
3, Selko-pH (Selko-pH): acid disinfectant, the main component is a complex organic acid, used for drinking water disinfection, dosage 1.0-3.0 ml per litre of drinking water.
4, Agricultural Blessing: Acid disinfectants, made of organic acids, surfactants and high-molecular-weight microbicide mixed. It kills viruses, bacteria, fungi, and mycoplasma. Conventional spray disinfection for 1:200 dilution, use 300 ml per square meter dilution; Porous surface or when there is an epidemic, diluted 1:100, use 300 ml per square meter dilution; disinfection pool for 1:100 dilution, at least each Change once a week.
5, acetic acid: acid disinfectant for air fumigation, according to 3-10 ml per cubic meter of space, plus 1-2 times dilution of water, heating evaporation. Animals and poultry can be sterilized, and doors and windows must be closed. Commercial vinegar can be directly heated and fumigated.
6, bleaching powder: Halogen disinfectant, gray powder, chlorine odor, insoluble in water, easy to absorb moisture decomposition, should be sealed, dry place storage. Fast and strong bactericidal effect, cheap and effective, widely used in barracks, the ground, septic tanks, excrement, vehicles, drinking water and other disinfection. Disinfection of drinking water can add 6-10 grams of bleaching powder to 1,000 kilograms of river water or well water, and it can be drunk after 10-30 minutes; ground and pavement can be sprinkled with water and sprinkled with water; faeces and sewage can be mixed in a 1:5 ratio while stirring. Add bleach.
