Disinfection refers to the killing or removal techniques or measures environment pathogens by physical, chemical, or biological methods. It may be farms, transport and various pollutants are reducing the number of pathogenic microorganisms in the lowest degree or harmless. By disinfection can kill pathogens in the environment, cut off the transmission, to prevent the spread of disease or spread. Because the majority of farmers do not have a clear concept for the disinfection of understanding, so let's focus on common sense tell us about sterilization. First, the main method of disinfection and sterilization methods can be generalized mechanism physical disinfection, chemical disinfection and biological disinfection. (A) physical disinfection method is through mechanical cleaning, washing, ventilation, light, heat, drying and other physical methods, and articles on environmental cleanup or kill pathogens. 1, mechanical cleaning, washing is the most common pathogen clear method of disinfection by mechanical cleaning, washing and other means, is one of the health work everyday. 2, sunlight, ultraviolet rays and other radiation exposure to sunlight is the most economical and effective method of disinfection by ultraviolet spectrum and the role of factors such as heat and dry can directly kill a variety of pathogenic microorganisms. 3, high-temperature sterilization is lead by the thermodynamic effects of pathogenic microorganisms in the denaturation of proteins and nucleic acids, and ultimately lead to the loss of the process of the biological activity of the pathogen, which is usually divided into dry heat sterilization and heat sterilization. Animal farm disinfection sterilization method commonly used flame burning. Burning flame sterilization sterilization effect significantly, the use of the operation is relatively simple. When pathogens resistant to, you can flame sterilization method of feces, venues, walls, cages, other waste burning, etc. sterilization, the dead livestock carcasses and contaminated feed, garbage incineration. (B) chemical disinfection disease prevention and control in the process, often using a variety of chemical disinfectants on pathogenic microorganisms contaminated sites, articles and other cleaning, soaking, spraying, fumigation, in order to achieve the purpose of killing pathogens. Mechanism of action that is bactericidal disinfectant way, there are three basic A, is to destroy the cell wall of the bacteria's cell wall or membrane perforation damage, leading to bacterial death. B, bacterial protein denaturation of the protein with a disinfectant cell degeneration, and loss of energy due to inactivation. C, surrounds the cell surface so that bacteria can not hinder their breathing gas exchange or metabolic activity and death. (C) the type of the selection of clinical disinfectants many disinfectants, divided according to the chemical properties of phenols, aldehydes, alcohols, acids, bases, chlorine agents, oxidizing agents, iodine agents, heavy metal salts and surfactants for effective and economical disinfection must carefully select the appropriate disinfectant according to the situation. Quality disinfectants should meet the following requirements. A, strong disinfection efficacy rapidly in a short time can achieve the desired disinfection purposes, such as sterilization rate of 99%, and the long duration of efficacy. B, disinfection can kill a wide range of bacteria, viruses, fungi, algae and other harmful microorganisms. C, sterilized by various methods such as water, spraying, washing, rinsing and the like. D, infiltration can penetrate into cracks and manure, dust, litter and other organic body kill pathogens. E, soluble in water without water hardness and pH changes in the environment affect the efficacy. F, stable against light, heat and impact, long-term storage effect diminished. G, for human and animal safety odorless, non-irritating, non-corrosive, non-toxic, no adverse side effects. H, the economic efficacy of low concentration can be guaranteed. (D) ensure disinfection measures: The main thing is to ensure that the disinfection effect directly in contact with the pathogen effective concentration of disinfectant. General disinfectant due to the presence of organic matter will affect the efficacy. Therefore, before disinfection must remove organic matter, therefore, need to take the following measures: A, remove dirt and other environments in the presence of a large amount of feces, pus, blood and other secretions, excretions, the pathogen will be organics mechanical protection, a large number of disinfectants combine with organic matter in the environment can not be completely kill pathogens. So, first the timely removal of the debris environment, on the ground, cages and so thoroughly washed, cleaned, after completion of chemical disinfection. Concentration of B, disinfectant should be appropriate within a certain range, the greater the concentration of disinfectant disinfection effect is more obvious. But not all products are suitable for sterilization, during the operation can not be blind to all disinfectants are increasing the amount of 70% as a good anti-virus effect of alcohol. C, different options suitable disinfectant microorganism according to the shape and the type of microorganism metabolism way, the degree of sensitivity of the different disinfectants. Gram-positive bacteria such as easy and cationic basic dye, heavy metal salts and detergents were inactivated binding; bacterial spores difficult to penetrate disinfectants, various disinfectants of different chemical structures and action mechanisms of microbial the extent of killing pathogens are also different. D, the effect of temperature and time for a proper temperature can enhance disinfection disinfection, sterilization and shorten the time used. When the ambient temperature increases as 10 ℃, phenolic disinfectants disinfection rate increased by more than 8 times, heavy metal salts to increase 2-5 times. Other things being equal, reaction time and disinfectants object to be sterilized in the longer, the better disinfection. E, control humidity fumigation, disinfection and humidity on the largest such time peracetic acid and formaldehyde fumigation, the relative humidity of 60-80%, the best, the humidity is too low, can greatly reduce the disinfection effect, In most cases, the humidity will reduce the concentration of disinfectant, generally after the spraying disinfectant rinse and dry. F, iodine disinfectant formulation pH should be appropriate, acids, Lysol Disinfectant bactericidal effect of acid anions in the enhanced environmental pollution; and cationic disinfectant benzalkonium bromide, etc. are added in an alkaline environment bactericidal power enhancement. (Five), bio-heat sterilization, is through the accumulation of fermentation, sedimentation tank fermentation, biogas fermentation heat or acid to kill, sewage, garbage and other internal pathogens approach. Second, the disinfection of animal building disinfection procedures: eliminate fecal → high pressure washing (on the ground, cages) → drying → → formaldehyde fumigation spray disinfectant (per cubic meter of space with 18 ml formalin solution, potassium permanganate 9 grams, sealed 24 hours). Dai Nam musk rat breeding farming cooperatives have the qualification certificate, are special support industry model units, has been working on musk rat breeding techniques, varieties cultivation, promotion of large-scale breeding, farmers win-win cooperation. Dai Nam musk rat farming cooperatives have comprehensive standardized farming methods, technology applications covering musk rat nest build homes, feed formulation, disease prevention, foster pups, breeding and reproduction, musk extract a series of farming practices, has "kind of rat birth rate, the youngest son of a high survival rate; low incidence of the disease, the cost of occupancy is low, "the" two high and two low "technical advantages. Cooperatives adhering to the "letter to the Road to excellent for the win" business philosophy, always adhere to the "left farmers, factory hand," the whole industry chain cooperation.
