600 fattening pigs were raised in a pig farm in Zhangshu City, Jiangxi Province. These pigs were immunized with classical swine fever, swine erysipelas, porcine lung disease, Streptococcus suis and so on. Recently some pigs are depressed, anaemia, dyspnea, most pigs constipation, fecal ball with lard-like mucus, in the middle and later stage sick pigs ear wing, belly, extremities color red first and then purple, resident veterinarian with gentamicin, penicillin, sulfonamides and other drugs at the same time with analgin treatment, the effect is not good, fever after a drug withdrawal and return to high fever, 12 died successively. Autopsy of dead pigs showed mucous membrane, pale skin, systemic jaundice, incomplete blood coagulation, body cavity effusion, liver, gallbladder, lymphoid enlargement, splenomegaly and softness. According to the immune procedure, medication and pathological characteristics, porcine eperythrozoonosis was diagnosed.
According to the diagnostic results, Benil 5Mel 8 mg / kg, once a day for deep intramuscular injection, even 1 Mel twice, or long-acting antimicrobial agents produced by Jiangxi Minxing can be used. If anemia is serious, dextran and other drugs can be injected at the same time. At the same time, do a good job in environmental hygiene and eliminate all kinds of blood-sucking insects, such as lice, mosquitoes and flies.
Analysis: this disease is most easily confused with influenza, toxoplasmosis, classical swine fever and other diseases, so in clinical practice, we should not only look at the symptoms and easily draw conclusions, but also make more comparisons and more autopsies, and send them to the veterinary department for chemical examination if necessary. The disease occurs all the year round, but it occurs frequently in summer and autumn. According to the experience of diagnosis and treatment, we especially remind veterinarians that the use of sulfonamides is strictly prohibited when the disease is not confirmed, otherwise it will aggravate the disease and cause death.
