atypical swine fever does not have the typical symptoms and pathological changes described in the textbook and atlas, so it is difficult to diagnose.
the course will slightly longer secondary bacterial infections (such as secondary lung disease, paratyphoid, actinobacillus pleuropneumoniae and haemophilus parasuis) showed changes in bacterial diseases cover primary swine fever diagnosis and medication difficulty caused by the truth. swine fever diagnosis requires fluorescence antibody test and enzyme-linked immunosorbent assay, but can not be achieved in pig farms and pig farmers. through a few years of clinical practice, summed up the following experience for reference:
at the same time, the following four conditions may be suspected of swine fever infection
(1) long term high fever (ji liure) reached 41 - 42 degrees;
, and purulent secretion in the eyes.
(2) continuous use of three days of antibacterial drugs ineffective.
(3) the course of disease occurred slightly in the abdomen, ears, tail and nose
at the end of cyanosis, and posterior paralysis phenomenon.
(4) dose of swine fever vaccine, vaccination time or vaccine itself;
find out the problem.
3 preventive measures
1 improve feeding management
according to the current serious viral diseases, recommended to choose the better use of virus strains such as iodine disinfectant.
2, strengthen nutrition, prevention of feed poisoning
mycotoxins can cause poisoning in pigs, so be sure not to buy cheap feed or raw materials. can be added in the feed to remove mildew static.
3 treatment measures
(1) hog cholera serum injection;
the swine fever was re administered 3 to 5 days after the disappearance of symptoms
vaccination.
(2) emergency vaccination of classical swine fever vaccine;
the treatment of atypical swine fever mainly lies in early diagnosis and early treatment,
the effect is better when there is no secondary infection. the dosage of vaccine is 15--25 head, which can be chosen according to the weight, size and duration of the diseased pig. at the same time, cooperate with the injection of immune enhancer (immune fluid, astragalus antitoxin, white blood cell interferon, etc.). 24 hours after vaccination, according to clinical symptoms, the right remedy, do not rigidly adhere to.
whether it is a high fever syndrome or other infectious diseases, the treatment is very difficult, so prevention is more important than treatment. rapid response is also an important measure to reduce the loss, rapid and accurate diagnosis, rapid treatment or eliminated decision. first of all, in time to isolate the incidence of pigs, to determine whether there is no therapeutic value, there is the risk of transmission, the treatment of pigs of little value to resolutely eliminated. remember, elimination is also an important way to reduce losses.
4 treatment measures:
symptomatic treatment
can not blindly use antipyretic, because the effect is not ideal, even if the fire down, and soon will rebound. the cause of death may be related to heart failure, lung and kidney failure, and injection of low temperature anorexia needle can be used to improve the intelligence.
some herbal detoxification has a unique role, most of the current antibiotic therapy under the premise of chinese medicine can try some heat, cooling blood, detoxification, such as muscle gland peptide, mixed tratch fever, high fever mixed serum, may have unexpected effects.
2) due therapy
1. caused by prrs, circovirus, swine flu and so on
muscle gland peptide no di (mixed), the other side of intravenous injection of blood mixed clear,
prevention and treatment: round blue bacteria poison resistance, high free discharge toxins, amoxicillin fed spices
2. unexplained fever and indigestion caused by various difficult miscellaneous diseases can be selected
high fever mixed serum and intramuscular injection were respectively done
prevention and treatment: avoid high row poison, mycoplasma static, potent mix of feeding high
3. multiple pathogenic infections or secondary infections leading to low resistance and induced anorexia or fasting can be selected
mixed tratch fever, high fever mixed serum were intramuscular injection can be serious with low temperature anorexia needle
prevention and treatment: blue circle radical, immune interferon, amoxicillin mixed feeding
4., by the red blood cells, toxoplasma secondary, chronic swine fever caused by non food or less food can be selected
muscle gland peptide, three red bow chains were injected separately
the prevention and treatment of disease, three: amoxicillin, polysaccharide interferon fed spices
chuang xin liu feeds
through more than three years of practice, the clinical treatment of thousands of cases, the effect is as follows:
the morbidity is 0 - 3 days, and the cure rate is 85%.
the morbidity is 4 - 7 days, and the cure rate is 70%.
more than 8 days after the disease, the cure rate is 50%. |
