What should be used for disinfection of chicken coops in farms?

Which disinfectant should be used for disinfection of farms? As time goes on, there will be more and more pathogens in chicken farms. Many farmers feel that chickens are becoming more and more difficult to raise, and the more they raise, the more sick they get. This is the reason. As the main means to reduce pathogenic bacteria, disinfection is not well understood by many people. Many people also use various disinfectants in the disinfection of chicken houses, thinking that using disinfectants is enough, but they don't know much about each disinfectant, just stay in the use of disinfectants, and don't know how effective it is and whether it is useful. Farmers often ask such a question: which disinfectant should I use? Today I will briefly share the advantages and disadvantages of disinfectants commonly used in aquaculture. Understand that disinfectants can be divided into the following four types according to their ability to kill pathogenic bacteria. Sterilizer: Kill all microorganisms. Advanced disinfection: kill all kinds of microorganisms including bacterial spores. Intermediate disinfection: kill all kinds of microorganisms except bacterial spores. Low-level disinfection: kill microorganisms with weak resistance. Commonly used disinfectants 1, alkaline disinfectants: the most common are quicklime and sodium hydroxide (caustic soda). Advantages: General disinfection effect is high, it is suitable for environmental disinfection, and its price is low. Disadvantages: it is irritating and corrosive, and has a great impact on the environment. 2. Aldehyde disinfectants: The most common are glutaraldehyde and formaldehyde solution. Advantages: Aldehydes have broad-spectrum, high-efficiency and quick-acting disinfection function, and its mechanism of action is that an active alkylating agent acts on amino groups, carboxyl groups, hydroxyl groups and sulfhydryl groups in microbial protein, thus destroying protein molecules and killing microorganisms. Disadvantages: Glutaraldehyde is stable under acidic conditions, which is convenient for long-term transportation and storage, but if it is heated during use, the effect will be better. Under the alkaline condition of pH 7. 5 ~ 8.5, its biological activity naturally reaches the highest. There are limitations and contradictions in transportation, preservation and clinical application, and the products need good research and development and production technology to support them. 3. Halogen disinfectants: the most common ones are mainly chlorine preparations (such as sodium dichloroisocyanurate and potassium persulfate composite powder (available chlorine >: 10%) and bleaching agents. ) and iodine preparations (such as povidone iodine). ). sodium dichloroisocyanurate: Advantages: Chlorine preparation plays a bactericidal role mainly by generating hypochlorous acid in water. Hypochloric acid can be adsorbed on the cell wall surface of bacteria, and penetrate into bacteria through oxidation to destroy its enzyme system, leading to microbial death. Disadvantages: Chlorine compounds have a particularly strong disinfection effect, but their properties are unstable and their forces are not lasting, so they are called "instant disinfectants". Povidone iodine: Advantages: The iodine preparation disinfectant can directly denature and precipitate protein in bacteria, leading to the death of pathogenic microorganisms, thus effectively sterilizing and killing viruses, bacteria, spores, fungi and protozoa. And has low toxicity. Disadvantages: similar to chlorine-containing compound disinfectant, it has instantaneous disinfection effect and strong bactericidal effect in acidic environment, but its bactericidal effect is weakened in alkaline environment and organic matter. 4. Oxidant disinfectants: common ones are: peracetic acid, hydrogen peroxide, potassium permanganate, etc. Advantages: peracetic acid has a strong oxidizing effect, which can oxidize the protein of bacteria and kill microorganisms. It has an efficient and rapid disinfection effect on a variety of microorganisms including spores and viruses, especially its own volatility can be used for fumigation and disinfection of animals or empty houses (neutralizing ammonia gas in pens). But be sure to dilute the dose according to the instructions. Generally, it is not recommended to use the stock solution directly. Peroxyacetic acid and hydrogen peroxide have no residue after disinfection and have no pollution to the environment. Disadvantages: The stock solution tastes of acetic acid, unstable and volatile. The stock solution is corrosive and irritating to metals (non-stainless steel) or animal tissues. 5. Phenolic disinfectants: 84 disinfectant, Lysol, coal phenol soap solution and compound phenol disinfectant are common. Advantages: Phenolic disinfectant has stable performance, low corrosiveness to articles, strong killing ability to various bacteria and enveloped viruses, and relatively affordable price. Disadvantages: Compound phenol contains 4 1%-49% phenol and 22%-26% acetic acid, which has good disinfection effect among many phenol disinfectants. This kind of disinfectant has special smell, protoplasm toxicity and carcinogenicity after long-term inhalation through the skin, and is mostly used for excreta disinfection. It is not recommended to use it indoors. It has an uncertain effect on mycobacterium tuberculosis and spores, and has a poor effect on non-encapsulated viruses. 6. Quaternary ammonium disinfectant: dicyandiamide and bromogeramine are common. Advantages: stable performance, low price, killing virus with capsules and fat solubility, and it is an inefficient disinfectant. Disadvantages: it is not effective for non-encapsulated viruses, and it is easily absorbed by various organic substances on the surface of objects, reducing the effective concentration. In the process of using disinfectants, we should not only understand the different characteristics of each disinfectant, but also pay attention to its alternate use in the process of use in order to achieve better results. 7. Potassium persulfate compound disinfectant: Advantages: 1. Multi-effect fusion NoProvian aqueous solution can produce a large number of hypochlorous acid, hydrogen ions and stimulated oxygen free radicals, taking into account the triple effects of chlorine preparation, acid preparation and oxidant. Wide bactericidal spectrum and strong bactericidal power. 2. Efficient and lasting. It has a strong bactericidal effect on various bacteria, viruses, fungi, parasites and eggs, and the effect lasts for 7- 14 days. 3. Safety and environmental protection. Non-toxic to animals, can be disinfected together with livestock and poultry, and has no influence on operators and no stimulation. It is the best choice for disinfection of livestock and poultry, which is non-corrosive and can prolong the service life of metal equipment. Routine disinfection: 1. Air disinfection (disinfection of livestock and poultry for spraying) II. Disinfection of surfaces and equipment: used for disinfection of surfaces of appliances and facilities such as floors, walls and cages. 3. Immersion disinfection: used for disinfection of hands, water boots, automobile tires, etc. The disinfection pool at the entrance of the farm, the washbasin in the disinfection room and the disinfection basin in front of the shed. 4. Waterline disinfection: disinfection of drinking water, waterline and aquaculture. 5. Disinfection of means of transport: used for disinfection of foreign vehicles and vehicles inside farms. To prevent the entry of external pathogens and the spread of internal pathogens.
