Disease of pig high fever shows in some places the pig causes disease of ill sex blue ear high only, but tell from the concept, this disease is to point to all diseases that can cause pig high fever to exceed 41 ℃ . The cause that causes this disease is cause of disease normally microbial infection, it is virus commonly kind, fine fungus, establish a gram body of second family name kind with helminth kind cause of disease. Besides high fever, infection of different cause of disease has different hair disease account and pathology feature, need is accurate make examine break, so that make,prevent effectively accuse countermeasure.
1, common cause of disease
The cause of disease that can cause pig high fever is more, the virus that virus of common acute communicable diseases having a pig, blue ear virus, cirque virus, flu virus and second head virus are a delegate kind cause of disease, pig infectivity pleura is pneumonic the bacili that put a line, erysipelas bacili, streptococcic, deputy pig is bloodsucking bacillus disease, cling to the fine fungus cause of disease that family name bacili and coliform organisms are a delegate, the haemal helminth that arched bug is a delegate kind cause of disease, add what body of red blood cell is a delegate to establish a gram body of second family name kind cause of disease. Once affect, can form virus blood disease or bacterium mostly, or release in field planting place send heat source, cause temperature to lift, cause airframe metabolization to strengthen, produce heat to increase, temperature rises.
2, prevent accuse a principle
Disease of pig high fever defends the basiccest principle that accuse is to prevent what after cause of disease is affected, generate to send heat source to enter blood, upset head issueing grave then the temperature setting dot of temperature adjustment centre, bring about airframe metabolization to strengthen, produce heat to be more than medicinal powder heat causes airframe to give out heat. Accordingly, this disease needs to undertake preventing accusing from two respects, the first make prevent infection of cause of disease, include 2 kinds to send infection and afterwards hair infection formerly. Former hair infection basically shows high pyretic cause of disease is affected directly, and after afterwards sends sexual infection to inbreak for the first cause of disease, bring about airframe to avoid drop, nerve is humoral adjust happen disorder, affect the 2nd kind thereby even cause of disease of the 3rd kind of above, clinical prevent when accusing, wu is sure both consider inside at the same time; The 2nd if had been affected,be, prevent to come on, basically prevent generation send heat source to develop physiology action to start the yield below thereby thermal conditioning function.
3, precautionary measures
Precautionary countermeasure need infects a source from control, cut off transmission way and easy feeling swinery 3 respects begin.
1) control infects a source. Control infects a source is those who prevent a disease the first close, at causing this ill cause of disease differ, each district but the epidemic situation specific aim according to our region accuse, basically be to be in process of pig farm introduce a fine variety, microscope immunity reports, the epidemic disease that avoids to avoid the cause of disease of epidemic disease or leaking strengthens quarantine, ensure the pig that introduce comes from the area that be not epidemic disease, after introducing, in segregation the area observes 1 week of above, after having unusual situation again admit produces a division, fill the vaccine that avoids leakage. Carriage car can be apart from berth in above of 50m leaving a pig, after the car leaves, to the wheel orbit undertakes alexipharmic. Management is strengthened in routine, prohibit producing personnel to contact a pig to peddle, the tall danger crowd such as personnel of slaughter of vet, hog, live pig also does not come in and go out to trade in the meantime the place such as the market, avoid to carry cause of disease pig farm, to the pig that has affected, need to be kept apart in time, prevent to enter easy feeling area.
2) cut off transmission way. When doubtful pig discovers in swinery, keep apart its instantly, according to contagion type the choice is treated, fall into disuse and burn bury processing greatly, diffuse in order to avoid, strengthen disinfection at the same time, cut off transmission. Disinfection must have specific aim on methodological choice, if can be diagnosed quickly, choose disinfectant and alexipharmic method according to disease popularity characteristic, if diagnose,be cause of disease of respiratory system sex, undertake alexipharmic to air mainly, strengthen at the same time ventilated, accelerate adherent and sick former dust particle eduction, the oldest rate avoids to enrage source sex transmission; If diagnose,be enteron systematization cause of disease, be opposite mainly common and waterline of crib, drink, implemental undertake alexipharmic, avoid get ill by the mouth; If be systemic sex appeal to catch kind of cause of disease to strengthen an environment to disinfect mainly, increase alexipharmic frequency, prevent epidemic disease to spread. Besides affecting place fractionize, still need to be changed according to the manage of cause of disease property, right outside resistance, whether the specific feature sieve such as generation gemma singles out optimal disinfectant and alexipharmic method.
3) protect easy feeling swinery. Easy feeling swinery did not contract cause of disease namely but did not obtain immune antibody again at the same time, the swinery that overpowering ab extra cause of disease invades. Protective plan has 2 kinds, one kind is through strengthening management, reduce raise density, avoid to should be stimulated, make swinery retains normal immune power; The 2nd kind is vaccinal have an inoculation, make the pig obtains factor of many immune antibody, cell and effect cell, when be affected by wild poison, can the resistance of specific aim. Of the value what carry is, in clinical production process, best 2 kinds of plan are used at the same time, make the protection of swinery is achieved optimal. Additional, cause of disease of a lot of sexes is easy produce mutation, or inferior model more, or vaccine still is in development phase, or preparation cost crosses advanced element, cannot carry protection of vaccinal immunity way, swinery must be protected below this kind of circumstance through strengthening put in order.
4, remedy
Plan of traditional tall pyretic treatment is to want a pig to give out heat only use antipyretic instantly, this is a serious error that use drug. Airframe gives out heat is a kind of expression that immune function is started and ill original work struggles, the purpose with calorific airframe is to restrain the breed of cause of disease, because the need in process of breed of cause of disease is enzymatic,participate in metabolization, if airframe is calorific, these enzymatic active can be affected, breed then also can be restrained, although calorific and normal cell metabolizes to also can be affected certainly, but integral benefit is more than fraud. Antipyretic is in long-term high fever the ability when be not being retreated is used, long-term high fever can make normal cell metabolization suffers airframe restrain time to grow too, contradiction can be changed now, fraud is more than benefit. Accordingly, clinical must grading uses antipyretic correctly.
The need when treating this disease cooperates to use antibiotic, somebody thinks virus kind infection need not antibiotic, this idea is incorrect, although antibiotic does not fight virus, but after virus is affected bring about airframe immunity easily to reduce, constituent cell is damaged, for the bacterium ill infection offers an opportunity that can be exploited to sbs advantage, antibiotic uses the objective that can have to prevent afterwards to send infection.
