Treatment of unknown hyperpyrexia syndrome in pigs

Although there are no specific drugs and mature treatment schemes available at present, after the outbreak of pig nameless high fever syndrome in production, positive measures should be taken according to the situation in this field to reduce morbidity and mortality and reduce economic losses. it's still a lot of good.

The main results are as follows: (1) disinfection is to cut off the way of transmission of epidemic disease and kill pathogens. After the outbreak of the epidemic in the pig farm, the disinfection work should be strengthened, and the concentration of the disinfectant solution should be increased. The epidemic area and its surrounding environment should be strictly disinfected 2 or 3 times a day, and the pig farm life management area should be disinfected once a day. Disinfection measures can play a good effect in preventing the spread of the disease.

(2) pigs that have been infected and diseased should not be vaccinated, otherwise the mortality rate will be even higher. Pig farms should be combined with the diagnostic situation, emergency vaccination of uninfected healthy pigs, it is best to be able to isolate influenza serotype strains to make influenza vaccine for emergency vaccination, and after an interval of 2 to 3 days, the dose of classical swine fever attenuated vaccine should be increased by 1 to 2 times, and one injection per pig should be strictly done during vaccination to prevent cross infection.

(3) after the outbreak of the epidemic, drugs should be added to drinking water and feed at the same time as soon as possible, combined with injection of antibiotics or biological products to treat diseased pigs in order to reduce the death caused by bacterial secondary infection.

For the prevention and control of whole-group administration, Jiakang 500g + doxycycline 300g / ton feed can be used for 14 days; as the feed intake of affected pigs is reduced, drugs should be added in drinking water at the same time, the compound preparation of antibiotics and traditional Chinese medicine extract which is effective to bacteria and viruses can be used, and good quality soluble multi-dimensional additives can be added to let pigs drink freely for 5 days.

The therapeutic effect of antibiotics in severe pigs is not ideal and should be carefully nursed. One of the injections of cephalosporins, compound doxycycline, penicillin and long-acting sulfonamides can be injected with astragalus polysaccharides or compound Bupleurum injection and compound Scutellaria baicalensis injection. The dosage should not be too high, otherwise it will accelerate the death of sick pigs.

Some pig farms try to control with injections such as transfer factor, anti-epidemic peptide and interferon, which has a certain effect. Multivitamins and antibiotics should be added to drinking water to reduce stress so as not to lead to higher morbidity and mortality.

Sick sows can use 50 ml of Houttuynia cordata, 30 ml of aminopyrine, 320-4.8 million units of amoxicillin, dissolved in 5% glucose saline, ear vein drip, 1500-2000 ml per day.

The drug treatment effect of diseased pigs with secondary infection and mixed infection of classical swine fever is not good, so we can consider using cured or tolerant pig serum, as well as non-infected sow serum or anti-classical swine fever virus serum for control. The typical disease materials of diseased pigs can also be collected under the guidance of relevant experts to do their own tissue vaccine for prevention.

(4) strengthening feeding management, taking good care of sick pigs, preventing heat and cooling, good ventilation and low density feeding. Do not drive away sick pigs violently, let alone wash pigs with cold water, otherwise it will aggravate the morbidity and mortality.

(5) the sick pigs with particularly serious condition and poor treatment effect should be dealt with promptly and decisively in order to prevent the spread of the disease. Sites and appliances contaminated by sick pigs must be thoroughly disinfected, dead pigs shall be dissected at designated places, bodies and wastes shall be burned, buried and other harmless treatment, and consumption or arbitrary abandonment shall be strictly prohibited.

(6) the sick pig farm should promptly report the epidemic situation to the relevant competent authorities, at the same time, close the pig farm, standardize the handling of dead pigs, and stop all behavior, so as to prevent the further spread of the epidemic.
