Modern livestock and poultry industry is facing the greatest threat to the livestock and poultry diseases, infectious diseases caused by the epidemic must be the source of infection, transmission and susceptible animals three links are indispensable. The source of infection is a disease in which the host pathogens, growth, reproduction, and can be excreted from the body or place animals, including animals suffering from infectious diseases, as well as carriers of the pathogen contamination of pathogenic microorganisms places. The source of infection in a variety of different ways to the surrounding environment from pathogens, often with feces, urine, nasal fluid, eye secretions, saliva, milk, skin ulcers secretions, blood, genital secretions, such as loss from the skin epithelium. Epidemics caused the most fundamental factor is the source of infection, it is necessary to the control of communicable diseases, the best way is to remove the source of infection, which is to eliminate the source of infection from pathogens.

So, how do we eliminate the source of infection in order to reduce the incidence of infectious diseases? Conduct scientific and effective disinfection is to reduce the occurrence of infectious diseases among the most important measures! Disinfection through science, culture reduce or kill pathogens in the environment, it reduced the number and concentration to the sound of the animal disease or prevent the spread of the disease. Here are some common sense disinfection:

First, the type of disinfection method
1, sanitation and disinfection method: clean, dry, scrubbing, painting, and other means to reduce pathogens direct approach.
2, physical disinfection method: Using sunlight, ultraviolet rays, and high-temperature flame means of the method of killing pathogens.
3, chemical disinfection method: use of chemical disinfection Pharmacy kill pathogens, the main method immersion, spraying, such as fumigation.
4, biological disinfection method: the use of microbial fermentation methods to kill pathogens, primarily for manure and dunnage.

Second, the main targets of disinfection
Disinfection is the main target of animal secretions, as well as waste contaminated sites, including Quan Shi, the surrounding environment, dunnage, utensils, clothing and keeping staff, Waxue, living environment, access to vehicles.

Third, the general disinfection procedures
To achieve satisfactory disinfection effect, we will certainly accordance with the scientific procedures. Animal Lanshi column of air disinfection in accordance with the following procedures: dry cleaning → cleansing →disinfection → cleansing → to further disinfection →dry cleaning, disinfection and in the process also stress the order, that is, from high in the end, from the side to the other side.

Fourth, a common disinfectant farm
Disinfection variety of drugs, by their very nature, can be divided into: alcohol, iodine category, acids, bases, halogen type, phenols, oxidants category, volatile Wanhuaji category, the following main commonly used on livestock farms Several disinfection Medicine:
1. Sodium hydroxide (also known as caustic soda, caustic soda or Huoxian): Bases disinfectant products for the rough white opaque solids, there are blocks, tablets, tablets, such as rod shape, commonly known as the state into liquid caustic soda solution. Mainly used venues, such as disinfection Lanshi. 2-4% solution can kill viruses and bacteria breed type, 30% solution for 10 minutes can kill spores, 4% solution 45 minutes to kill spores, such as the addition of 10% salt can kill Bacillus enhance capacity. Practice often with a 2% solution for disinfection, disinfection 1-2 hours later, the water clean.
2. Lime (lime): Bases disinfectant main ingredient is CaO, water top of calcium hydroxide, Common name lime or slaked lime, a strong alkaline, but water-soluble small dissociation from the small hydroxide ions, Disinfection role is not strong. Liquid Egg with Limewater killed one percent of the propagation of bacteria in general to a few hours, 3% Liquid Egg with Limewater one hour to kill salmonella, tuberculosis and Bacillus invalid. Its greatest feature is easy to get cheap. Practice, lime water 20 to 100 copies made of lime, for brushing the wall, Lanshe, ground, and so on, or directly by the increase in lime disinfection liquid, or scattered over the wet ground, and around Fenchi Washuigou etc. disinfection.
3. Be subject to the new (Selko-pH): acid disinfectant main component is a compound of organic acids for the disinfection of drinking water, the amount of water added 1.0-3.0 ml per litre.
4. Farmers blessing: acid disinfectant from organic acids, surfactant and polymer volume mixture of microbicides. The viruses, bacteria, fungi, mycoplasma, have killed role. Conventional spray disinfectant for 1:200 dilution, the use of diluted per square metre of 300 ml; porous surface or the disease, a 1:100 dilution, the use of diluted per square metre of 300 ml; disinfection pool for 1:100 dilution , at least once a week to replace.
5. Acetate: acid disinfectant for air fumigation disinfection, 3-10 ml per cubic metre of space, plus 1-2 times dilution water, heating evaporation. Be allowed to bring livestock, poultry disinfection, at the doors and windows should be closed. Commercial Suancu direct heating fumigation.
6. Bleaching powder: halogen type of disinfectants, gray powder, chlorine smell, difficult to dissolve in water, easy to moisture absorption decomposition, confined to dry the store. Bactericidal action fast and strong, inexpensive and effective, widely used Lanshe, floors, Fenchi, excretion, vehicles, such as drinking water disinfection. Disinfection of drinking water in the river or well water 1,000 kg increase in the 6-10 grams of bleaching powder 10-30 minutes after drinking can be; ground and the road can be spread to dry sprinkler; feces and sewage can be 1:5 dosage, side Stirring, joined the side of bleaching powder.
7. Chlorine dioxide disinfectant: halogen type of disinfectants, is a universally recognized powerful new generation of broad-spectrum disinfectant, and by the World Health Organization as A1-efficient security disinfectant, chlorine disinfection is 3-5 times can be Animal used in vivo, water, fresh feed disinfection preservation, Lanshi air, the ground, facilities, environmental disinfection, deodorant; on the use of this safe, convenient and powerful Xiaosha deodorant, use low prices per unit area.         
8. Disinfection Granville (sodium dichloroisocyanurate): halogen Disinfectants and easy to use, mainly for breeding sites and spraying disinfectant soaking disinfection, can also be used for drinking water disinfection, disinfection of the environment, which can carry livestock, poultry disinfection . Manual, marked by the use of disinfection and dilution ratio target preparation.
9. Sodium dichloroisocyanurate smoked agent: halogen type of disinfectants, disinfection of the materials used in sericulture and animal Lanshe, keeping appliances disinfected use, 2-3 grams per cubic metre of space, Animal placed Lanshe, Jamsil, closing doors and windows, ignited after the leave, confined 24 hours, ventilation can be; can be used for the mushrooms, vegetable greenhouses disinfected.
10. Poisoned 100: double-stranded quaternary ammonium broad-spectrum disinfectant, colorless, tasteless, non-corrosive and non-stimulation, which can carry livestock, poultry disinfection. 3/10000 or consequential preparation for the concentration of livestock Quan Shi, the environment, appliances, eggs, hatching room disinfection of drinking water for the ten thousandth the concentration of disinfectant.
11. Eradication of drugs: double-stranded quaternary ammonium compound disinfectant sterilization, with broad-spectrum, highly efficient, non-toxic, and other characteristics of the viruses, bacteria, mold and have to kill pathogens such as Mycoplasma role as a drinking water: 1500-2000 dilution; daily on the environment, Lanshe, disinfection equipment (spray, washing, soaking) for 1:500-1000 dilution; incidence when diluted 300 times.
12. Formalin: aldehydes disinfectant, containing 37-40% aqueous solution of formaldehyde, a broad-spectrum bactericidal action of the bacteria, fungi, viruses, and spores so effective in the presence of organic matter is also a case kind of a good disinfectant deficiency is a pungent odor. Solution to 2-5% for spraying walls, floors, appliances and discharging disinfect premises fumigated with formalin per cubic metre of space 30 ml, placed in a larger container (at least 10 times the volume of drugs ), and 15 grams of potassium permanganate, prior clearance for all doors and windows closed fumigation 12-24 hours, then open the doors and windows to taste. Fumigation is not the best at room temperature below 15 ° C, relative humidity of about 70%.
13. Peracetic acid: antioxidant Disinfectants, pure clarity is a colorless liquid soluble in water, a strong oxidant, a broad-spectrum bactericidal effect, the role of fast and strong, and can kill bacteria, mold spores and viruses , instability, is to use the existing service. 0.04-0.2% solution for corrosion-resistant small items immersion disinfection time 2-120 minutes; 0.05-0.5% or more spray, spray disinfectant, anti-personnel should wear goggles, gloves and masks, spray after closed doors Window 1-2 hours by 3-5% solution heating fumigation, 2-5 ml per cubic metre of space, windows and doors closed after fumigation 1-2 hours.

Fifth, the factors affecting disinfection
1, the choice of sterilization drugs: General virus on the base, more sensitive to formaldehyde, phenols and the strong resistance, the majority of drug disinfection of bacteria have a good kill, but on the formation of spores of Bacillus and the virus is very small , and the disinfection of different pathogens the sensitivity of different drugs, therefore, the choice of disinfection against drugs should be disinfected object, targeted, the right choice.
2, disinfectant concentration: the use of disinfection should be read carefully before drug brochures, according to different targets and objectives, according to the concentration of disinfectant best prepared, under normal circumstances, the greater the concentration, the better the effect of disinfection.
3, disinfection time: different pathogens on the drug sensitivity of the different disinfection not the same, the time required to kill pathogens are also different, and the longer the general disinfection, disinfection better. Drugs such as spraying, the general requirement to maintain at least more than 20 minutes before washing.
4, temperature and humidity: disinfection and temperature are related, the higher the temperature, the better the effect. Fumigation and other disinfection, the humidity is required, the general requirement to maintain relative humidity in the 65-75 percent.

Sixth, the use of drugs for attention disinfection
1, asked for the preservation of disinfection medicine in a cool, dry, dark environment, otherwise it will create
Disinfection drug moisture absorption, and analyzing failure.
2, the purchase and use of drugs to the attention of disinfection overpack on the production date and durability must be valid for use.
3, the actual use, so as not to the different types of drugs mixed use of disinfection to prevent antagonism with the reaction of the two components, weakened or even lost disinfection role.
4, disinfection pool disinfection drug should be regularly swap in order to ensure effective disinfection.
5, immunization days before and after a day (a total of three days) does not spraying disinfectant drugs, the day after 2-3 days (of 5-7) not allowed to drink water containing disinfectant drugs, otherwise, it will affect immune effects.
