Understanding of disinfectants and rational use of disinfectants are issues that should be taken seriously by every pig farm and its associated managers. Here are some commonly used disinfection drugs to do a brief introduction.
1. iodine 5% iodine tincture for disinfection of surgical site, trauma and the injection site. Cotton with iodine (and then smear local alcohol deiodinase). This product has strong bactericidal ability, not easy to be inflamed after use, and has little tissue toxicity and strong penetrating power. It is the necessary skin disinfectant for every pig farm.
2. alcohol market alcohol is often 96%, with water for 70% alcohol, disinfection effect is good. 70%, alcohol soaked cotton block, then made of commonly used alcohol cotton. This product has the characteristics of dissolving sebum, cleaning skin, quick sterilization and little irritation. For needles, thermometers, skin, fingers and surgical instruments, disinfection is an essential disinfectant.
3. gentian violet (Jia Zi) 1% solution of tissue toxicity, no irritation, dry pull convergence effect. Commonly used in the inflammation of the skin and mucous membrane infection, ulcer and abscess pus discharged after disinfection.
4. Lysol water (Cresol Saponatus Liquid 2% solution used for instruments, wound disinfection, arm. 3%~ 5% solution for disinfection, trough, piggery floor sink, utensils, etc. the site. It can be sterilized with pigs because of its small side effects.
5. hydrogen peroxide (hydrogen peroxide) 3% solution, this product through organic matter released nascent oxygen, has bactericidal effect. Mainly used for purulent wound, deep tissue trauma and necrosis and other disinfection.
6. benzalkonium bromide (benzalkonium bromide) this product is a surface active disinfectant, can not be used simultaneously with soap because it counteracts the disinfection effect. Commonly used 0.1% solution, used for hand, skin, surgical instruments, irrigation, mucous membranes and work clothes disinfection.
7. Potassium Permanganate (potassium permanganate) this product is a kind of strong oxidant, has bactericidal effects on bacteria and viruses. Commonly used 0.1% solution, used for pig breast disinfection, purulent wound, ulceration, flushing and so on.
8. caustic soda (sodium hydroxide, caustic soda, caustic soda) this product has a strong role in the killing of bacteria and viruses, 2-3% solution for piggery floor, crib, water disinfection, disinfection can be put into the pool as a disinfectant, disinfection and can be used for infectious diseases and environmental pollution site. This product can not be disinfected with pigs, so as not to burn the skin.
9., 16-23%, this product is a strong oxidant, virus, bacteria and other bactericidal action, at 0 degrees below the low temperature is equally effective. This product can be used for spraying 1:200-400 diluted piggery, ground, crib, sink, environmental disinfection. 1:500 times dilution can be used for clothing, arms or disinfection with pigs. Especially for the prevention and control of sudden foot and mouth disease.
10. bacterial toxin (phenol, acetic acid, twelve alkyl benzene sulfonic acid). This product can kill influenza, swine fever, foot and mouth disease, epidemic diarrhea, blue ear disease, circovirus and so on. It can also be used for emergency disinfection of avian influenza and Newcastle disease. The utility model can be widely used for livestock and poultry houses, aisles, fields, utensils, instruments, excrement, pollutants and vehicle disinfection. Use concentration 1:300-500
1 thousand and 100 toxicity elimination (povidone iodine) used for pig house, pig body surface and environmental disinfection. Also used for surgical instruments and surgical sites for disinfection. It can kill all kinds of viruses and bacteria. Drinking water disinfection 1:: 2000; environmental pens, disinfection equipment, vehicle 1:1500; livestock or poultry (spray) disinfection 1:1500.
12. bleaching powder (chlorinated lime), this product is a white powder, with a sharp chlorine odor, strong bactericidal and deodorizing capabilities. 10% ~ 20% bleaching powder, used for pig house, transport of pigs, vehicles, the environment, manure, soil, sewage and other disinfection. From 1% to 3%, for clear liquid tank, disinfection equipment.
13. formaldehyde (40% Formaldehyde Solution is Faure Marin), this product has a strong reduction, can make protein denaturation, with a strong bactericidal effect. 2% formalin is used for disinfection of instruments. When the pig house is fumigated, the room temperature is 20 DEG C, the relative humidity is 60%~ 80%, the doors and windows are airtight and the air is not leaking. Per cubic meter of space Faure Marin 25 ml, 12.5 ml water, 25 grams of Potassium Permanganate. The formalin and water into a container, add Potassium Permanganate; formaldehyde vapor evaporates quickly, people should leave quickly. Disinfection time is best for more than 24 hours. Attention should be put in formalin and water, after the release of Potassium Permanganate.
14. lime 10% ~ 20% lime milk, brush pig house, walls, railings, ground and so on. Can also be scattered on the ground, wet lime pig, septic tank and sewage around the ground ditch etc..
15., grass ash, water ash 2 kg, 10 kg water mixture, boil 2 hours, with sacks and other materials filter standby. When using hot water for disinfection and two times of dilution, sprayed pig ground, railings, utensils, and other contaminated sites. This product is an alkaline solution, bactericidal force is very strong.
Matters needing attention in the use of disinfectants
1, the dilution concentration in the scheme is the minimum concentration needed to kill the most resistant pathogenic microorganisms.
2, the dosage of any effective disinfection, must thoroughly wet the sterilized surface.
3, disinfectant action time should be as long as possible, keep disinfectant and pathogenic microorganisms full contact, generally 1 hours or more, the effect is better.
4. Clean the sanitation before disinfection and eliminate the harmful factors (feces, urine, garbage) as much as possible.
5, with the current match, mixing evenly, avoid side with water disinfection.
