Prevention and treatment of Pig High Fever

With the change of the weather and the arrival of winter, a cold wind sounded the alarm of the cold winter. People are called on to keep warm and resist the cold wind, but who can resist the infection of bacteria to our poultry? Now that bacteria are increasingly rampant and bothering us, I think it should have something to do with our law of life. the following is a brief introduction to the symptoms, prevention and treatment of pig high fever: clinical symptoms, pig spirit, loss of appetite or stop eating, have a small amount of appetite. The diseased pigs had persistent high fever with a body temperature of 41 ℃ ~ 42 ℃ and 43 ℃ in some cases. There are varying degrees of skin flushing, finger pressure fading, mental fatigue. There are tear spots in the eyes, increased secretions, conjunctivitis symptoms, severe abdominal breathing, shortness of breath, cyanosis in the ears, purplish red patches or bleeding spots in many parts of the body, such as limbs and abdomen, and hand pressure does not fade. In the later stage of the disease, yellow watery feces, less and turbid urine, dark yellow color, dying pigs appear watery neurological symptoms, and arthritis, it is difficult to stand up with few and red-yellow urine, constipation, fecal constipation ball-shaped stool, lethargy. There were varying degrees of swelling of body surface lymph nodes, shortness of breath and flushing of visible mucosa in some cases. With the extension of the course of the disease, the skin of the ear, lower neck, abdomen, limbs and tail became purple and did not fade. In some cases, the skin on the surface of the body gradually changed from pallor to yellow staining, and the desire for diet was abolished. Most of the course of the disease was about 20 days, and finally died of failure. Pathological changes dissected the three dead pigs: lung swelling, bleeding, hardening, marble-like brown mottled lesions, uncontractile rubber lungs, obvious symptoms of interstitial pneumonia, suppurative foci, pulmonary interstitial enlargement; enlargement and bleeding of inguinal and hilar lymph nodes; kidney swelling, brittleness, needle-like bleeding spots; liver swelling, degeneration and necrosis; splenic infarction The intestinal mucosa is damaged and ulcerated; the pulmonary serosa adheres to the pleura or pericardium. Take measures because the pigs are mainly fed on leftovers from nearby factories and some green vegetables from potato rattan seedlings, farmers feed the leftovers directly to the pigs without re-boiling and cooling, resulting in poor gastrointestinal tract and resistance, and are easy to be infected with a variety of diseases. Therefore, first of all, it is suggested that the farmer should boil the leftovers of the soup before feeding them to the pigs. In view of the fact that the pig farm has been infected with bacteria and viruses that cause unknown high fever, the key to the prevention and treatment of this disease is to adhere to the policy of prevention and prevention. therefore, it is suggested that farmers should consolidate their awareness of epidemic prevention and strengthen environmental isolation and disinfection to prevent the spread of the disease. Keep the pigsty clean and dry, spray and disinfect it with 0.5% peracetic acid once a week, and sprinkle lime powder around the pigsty. After the discovery of diseased pigs, first, pigs with high fever and positive tests for blue-ear disease must be injected with attenuated blue-ear disease vaccine in time; for those farmers who have not developed blue-ear disease but are under greater threat from blue-ear disease, pigs should be injected with inactivated vaccine; the fluctuation of the disease in some areas is related to the discontinuation of blue-ear disease vaccine. Second, the prevention of atypical swine fever must be strengthened, as classical swine fever is an important cause of high mortality in "high fever" cases, it is necessary to ensure that the immune effect of classical swine fever is in place, and the third is to select effective antibiotics to control secondary infection. antibiotics can be selected by drug sensitivity test Fourth, according to the different pathogens of the disease (such as mycoplasma, Toxoplasma gondii, etc.), choose symptomatic drugs for prophylactic administration or treatment to reduce the loss caused by the disease; fifth, some drugs that can increase pig immunity are used for prophylactic administration or treatment, which has a certain effect. Sixth, timely elimination of rehabilitation breeding pigs, generally after treatment and rehabilitation of breeding boars and sows, often lead to low litter size, high abortion rate, and the utilization value is affected. -- give me a head.-- Thank you!
