With the increase of breeding farms, the development of the breeding industry has entered a stage of development, but due to the development, intensification, and growth of breeding farms, the high level of breeding farms has been increasing, and these pathogens have grown under appropriate conditions. Epidemics caused by epidemics, such as swine fever, sick feet, blue ears, swine circovirus, avian influenza, high fever, etc., the faster the original spread, and the outbreak, the way to go again is often too late , Will cause serious economic losses.
Disinfection is an important meaning in a comprehensive disease. Through scientific, reasonable and effective disinfection and transmission of infection, reducing the number of pathogens in farms and poultry houses can reduce or reduce the avoidance of daughters to a certain extent. happened.
The application range of saline-alkali water/chloric acid water has gradually expanded over time. Today we will briefly introduce the detoxification effect of sub-water/hypochlorine water caused by acid once.
Part.1
Foot and mouth disease virus (FMDV)
Foot-and-mouth disease virus is an RNA virus that can cause foot-and-mouth disease. Foot-and-mouth disease is an acute, febrile, and highly contagious infectious disease that is common to major domestic animals such as pigs, cattle, and sheep and other domestic and wild cloven-hoofed animals. There are more than 70 susceptible animals. It can cause acute fever symptoms, blistering rash on the oral mucosa, hoof and breast skin, and high mortality in young animals. The disease spreads in many ways and fast, and it has repeatedly spread worldwide, causing huge political and economic losses.
Vuong N. BUI of Hokkaido Agricultural University in Japan and others studied the killing effect of acidic electrolyzed water on foot-and-mouth disease virus. The results showed that acidic electrolyzed water (pH 2.6, ORP between 1109~1112mV) and foot-and-mouth disease virus suspension were mixed for 2 minutes at a ratio of 9:1. This treatment can effectively kill viruses, reducing the number of viruses with RNA activity from 106 to less than 102, and the virus inactivation rate is >99.99%.
Part.2
Avian influenza virus (AIV)
Bird Flu (Bird Flu or Avian Influenza) is the abbreviation of avian influenza, which is an acute infectious disease caused by a subtype of influenza A virus (also known as avian influenza virus). The morbidity and mortality of avian influenza vary greatly. When a highly pathogenic avian virus is infected, the morbidity and mortality can reach 100%.
Shio Tamaki of Hokkaido Agricultural University, Japan, and others studied the killing effect of neutral electrolyzed water on avian influenza viruses, using neutral electrolyzed water (effective chlorine concentration ≥43ppm, pH between 6.4 and 7.4) and high pathogenicity respectively. Avian influenza (H5N1) virus and low pathogenic avian influenza (H9N2) virus were mixed at a ratio of 9:1 and treated for 1 min. Treated under this condition, the neutral electrolyzed water can have a good killing effect on the virus, the number of active viruses is reduced by more than 5 logarithms, and the inactivation rate is >99.999%.
Part.3
African Swine fever (ASF)
African Swine fever (ASF) is an acute, virulent, and highly contagious infectious disease caused by the African swine fever virus (ASFV) infecting domestic pigs and wild boars. It is listed as a statutory report by the World Organization for Animal Health (OIE) Animal diseases are also listed as a type of animal epidemics that my country has to focus on.
Chae Hong RHEE of the Korea Animal and Plant Inspection and Quarantine Bureau and others published their latest research in the world-renowned veterinary journal "The Journal of Veterinary Medical Science": The killing effect of acidic electrolyzed water on African swine fever virus and avian influenza virus!
The researchers used acidic electrolyzed water with different effective chlorine concentrations (FCC) to test the effect of acidic electrolyzed water on reducing the titer of African swine fever virus (ASFV) under different organic concentration conditions. The results are as follows:
Under low-level organic pollution conditions, AEW with FCC≥40ppm is effective against African swine fever virus; under high-level organic pollution conditions, AEW with FCC≥80ppm is effective against African swine fever virus.
Part.4
Porcine reproductive and respiratory syndrome virus (PRRSV)
Porcine blue ear disease is a highly contagious disease caused by porcine reproductive and respiratory syndrome virus (PRRSV) that infects pigs, causing pigs to develop an acute and highly contagious disease characterized by reproductive disorders and respiratory symptoms Viral infectious diseases can cause piglet reproductive disorders, breathing difficulties, blue-purple ears, and other infectious diseases, which seriously affect the pig industry.
The disease spreads quickly, especially in technologically advanced and economically developed countries. Due to the dense and frequent movement of pigs, it is more likely to cause epidemics. After a severe epidemic period, the disease is often local epidemic, long-term harm to pig production, causing huge economic losses to the pig industry.
Hao Xiaoxia and others studied the killing effect of neutral electrolyzed water on pig blue ear virus, and the results showed that neutral electrolyzed water has a better killing effect on pig blue ear virus, and with the increase of effective chlorine concentration and treatment time The killing effect is enhanced. The effective chlorine concentration of neutral electrolyzed water is greater than or equal to 50mg/l, and the treatment time is 10 minutes, which can completely kill the pig blue ear virus with a half cell infection (TCID50) of 106.0/0.1 ml, and the killing rate is 100% .
