After each use of live vaccine empty vials should be concentrated into a plastic bucket with a lid sterilization treatment to prevent the spread of the virus, available disinfectants: iodic acid 1:100 diluted solution, chlorpyrifos 1:100 diluted solution.
Empty barn empty house terminal disinfection procedures
Generally in some kind of infectious disease subsided or after the pig house empty barn, the need for the environment and each of the pig house for the terminal disinfection, the measures are as follows:
1, cleaning
Swine manure and garbage of the high degree of contamination, but also the main source of infection, so it must be thoroughly cleaned up.
①Pig house if there are pigs, pigs should be driven out, and move out of the feed and drinking water equipment, pens partition, etc., and clean them; ② brush, knife or mechanical scraper to remove all the feces and contaminated bedding in the area disinfected and the remaining feed; ③ removal of feces and contaminated bedding can be buried, incineration or other harmless treatment.
2, cleaning
No cleaning process can not get rid of all the infectious pollutants, and therefore after cleaning to use the disinfectant with decontamination and sterilization effect of the walls and floors for cleaning and decontamination, for this purpose of 1:1500 iodic acid or 1:1500 glutaraldehyde solution, with pressure spray washing machine for spraying and washing, the amount of disinfection of about 1 liters of disinfectant per square meter of area. The dosage is approximately 1 liter of disinfectant per square meter of surface area. Rinse first from the roof of the house, and then along the walls all the way to the floor spray, while paying attention to cleaning the dead corners and dirty accumulation of places.
3, drinking water system and equipment cleaning and disinfection
All water supply systems generally have microbial contamination, especially storage tanks or pools, etc. is the dust and dirt easy to accumulate, the cleaning and disinfection of which can remove the presence of microorganisms.
①Drainage system
Drainage system in the main pipeline to unload the storage tank, and from the furthest end of the storage tank will be drained, to remove the accumulation of dirt in the storage tank, refill the water, and according to the end of the water concentration of 5-8 ppm requirements, according to the water per ton of water by adding 20-50 ml of Thytoxicidin / iodic acid to flush the drainage pipe, to maintain the drain for 30 minutes, and then re-fill with fresh water. For non-drainage systems and poor water quality, contaminated water supply
water system, can also refer to the "drainage system" treatment.
②movable equipment will be moved out of the equipment, such as feeding and drinking equipment, pig pen partitions, etc. may be contaminated with pathogenic microorganisms, the following measures can be taken to clean: soak the equipment in a pool and scrub, or 1:2000 iodic acid disinfectant spray disinfectant, will be placed in a place where the treated equipment is not contaminated.
4, disinfection
After cleaning, the degree of contamination of pathogenic microorganisms, especially viruses may still be high enough to pose a serious threat to sensitive young pigs or just introduced pigs, so it must be thoroughly disinfected to kill a variety of pathogenic microorganisms, depending on the disinfection of different objects can be used to disinfect the Wei, the whole of the security, bacteriophages, green power to eliminate, iodic acid, caustic soda, peroxide acetic acid disinfectant, etc. These disinfectants can not only kill the pathogenic microorganisms, but also can kill the bacteria.
These disinfectants can kill both bacteria and viruses, as well as bacterial germ cells,
belonging to the broad-spectrum, high-efficiency, low-toxicity (in addition to caustic soda), low-residue disinfectants.
Use 1:500 Chlorothalonil disinfectant solution or 1:300 iodic acid solution to carry out comprehensive spray disinfection and immersion disinfection of non-metallic products (utensils) (maintenance time 25-30 minutes), spray disinfection per square meter of surface (such as the ground, walls, etc.) with a prepared disinfectant solution of 300 ml.
When spraying, pay special attention to places where dirt is easily left behind, such as corners, cracks, seams and surfaces that are easy to penetrate, and the order of spraying is first the roof of the pigsty, and washed along the walls to the ground. When the cleaned surface is dry, then introduce the pigs.
5, space spray disinfection
Space (air) disinfection of the pig house is also very important for modern intensive farms, especially to reduce respiratory diseases is very effective. Use 1:1200 glutaraldehyde or 1:800 chlorothalonil for air spray disinfection, 500 ml of prepared disinfectant solution per square meter, once every 2 days at an interval, *** for 2 times.
Precautions:
①Carefully choose the disinfectant (it is best to choose under the guidance of experts to use).
②Disinfection procedures need to choose a responsible disinfector to implement.
③Disinfection measures should be combined with other measures to achieve good results
Summary:
The so-called disinfection is to kill the pathogenic microorganisms, which constitutes the core of the epidemic prevention in the current pig farming industry. Disinfection can control the occurrence of livestock infectious diseases, is to kill or kill the pathogen, cut off the best way to spread the disease. A large number of practical results show that strict disinfection can reduce the incidence of disease on the farm to 80%. That is to say, good disinfection work can bring greater economic benefits to the farm safety production
