it is clear to you that "high fever" is not the name of a disease. "high fever" is a symptom that can cause an increase in body temperature. some diseases are known as "high fever". high fever is one or more virus infection or secondary bacterial infection, the disease symptoms become complex or atypical. there are mainly related to the pig blue ear disease, circovirus disease, haemophilus parasuis, pseudorabies, eperythrozoon etc..
current characteristics of swine high fever:
1, occurring in the high temperature season, the disease process is long, generally in 5~20 days or so, the mortality rate is high, reaching more than 90%.
2, pig farms do not pay attention to the epidemic prevention work, and the technical staff have poor concept of health care. there is no strict closed pig farm, and the pig farm with systematic health care is not serious.
3, the incidence of pig weight generally in 20 ~ 80kg, the highest incidence, but also after weaning piglets and sows incidence.
4, the effect of drug treatment is not ideal, indiscriminate use of pig farms higher mortality.
clinical symptom
the onset of the pig body temperature increased to 40 ~ 42.5 deg c, depression, decreased feed intake or appetite waste away, suffering from pig skin redness, ear ear edge cyanosis, abdomen and legs endings multiple skin patches, with purple red; dyspnea, like recumbent pigs, part of abdominal breathing, severe the shortness of breath or asthma, some showed irregular breathing; some have swine runny nose, sneezing, coughing, eye secretions, most pigs have tear stains, causing conjunctivitis symptoms; some swine feces constipation, constipation, spherical, yellow urine, and less turbid, color. slightly longer course of disease, pigs pale, anemia, hair rough disorder, part of the disease, the hind legs of the pig weakness, the individual diseases of the pig can not stand before dying, and finally died of convulsions. the mortality rate is high in some pigs, and even 90% in some pig farms. some sows have miscarriages in the late pregnancy (100~110 days), stillbirths, mummies, and mummies. in combination with the above, experts have identified it as "swine fever."." this is a disease of many diseases, and take "prevention first, prevention and control combination" comprehensive prevention and control measures. here's some of my preventive measures and treatment experience introduced to you:
(a) strengthen management, improve the capacity of resistance to the scale of farming field closed management, establish and improve and strictly enforce the animal epidemic prevention system; backyard farmers and small farms, according to the practical, efforts to improve the feeding and management conditions, good ventilation disinfection, insecticide, sunstroke prevention cooling barns and sanitation work. to ensure adequate clean drinking water, and in the drinking water to add high immunity toxins, and at the same time in the diet to add more polysaccharides, interferon and gold growth peptide, trace elements, improve the body resistance of pigs.
(two) to strengthen immunization and ensure the immune effect, "pig high fever" is a syndrome caused by a variety of pathogens such as swine fever, pseudorabies, streptococcus suis and so on. farms (households) should strengthen the immunization of vaccines such as classical swine fever and streptococcus suis, improve the immune level of the whole group, and timely replenish the newly purchased live pigs to ensure the immune effect.
(three) disinfection of pathogens, purifying environment and clean house site, and then rinse clean, disinfection and other toxic bacteria disinfection medicine of iodine pens, aisle, ceiling and playground and spray. eliminate mosquitoes, flies, and reduce the spread of diseases. the waste must be treated harmlessly, such as stacking, fermentation, disinfection, etc..
(four) rational use of drugs to reduce losses
1. viral diseases are treated with antibiotics to prevent bacterial secondary infection. the application of chinese medicine prescription or proprietary chinese medicine such as jin qi, poison, epidemic resistance and so on to maintain the nutrition drugs and maintain the body resistance to diseases.
2, clinically confirmed as parasitic protozoa diseases, as soon as possible to use effective drugs to adequate dose, and must comply with the provisions of the course of treatment. of eperythrozoonosis in application of high blood chain fast treatment for treatment of swine toxoplasmosis, application of morninglight honggong chain treatment. the pig disease do harm to the pig production, pig disease prevention should take comprehensive measures to implement the "prevention first" approach, by strengthening feeding management, strengthen disinfection work, symptomatic treatment and other measures to reduce the incidence and mortality of this pig to get the big profits. 1 pig high fever, also called highly pathogenic blue ear disease, variant blue ear disease. the 2 main symptoms of swine high fever: pig body temperature generally about 39.5 to 41.5, often do have a cough, asthma, loss of appetite, secretion, dry and hard, with the development condition of the pig's ear, neck, buttocks hair purple, and other symptoms. if you use the fever after the drug, there will be repeated rebound, severe can be directly fatal.
3, swine fever caused by: a variety of diseases caused by diseases, the reasons are not clear.
4, treatment method: improve the environment, provide full price of feed, improve immunity, can use gold qi poison resistance high detoxification toxin polysaccharide interferon, mixing feeding
intramuscular injection of morninglight no. 2 fast ice (mixed), mixed tratch fever
in severe cases, the tip of the pig's tail and ears are cut off to promote blood flow (to promote circulation of the blood).
