1. Porcine reproductive and respiratory syndrome: for the Nidovirus order arteritis virus family; Pregnant sows and piglets are the most common and are a class of diseases in China; Features: persistent infection of the virus, diffuse interstitial pneumonia, marble-like appearance of hilar lymph nodes. Diagnosis: Porcine alveolar macrophages are inoculated with the disease material, stained with immunoperoxidase, and the RT-PRC method is more effective in examining the diseased RNA-PRC method in alveolar macrophages.

2. Porcine parvovirus disease: mainly occurs in sows, stillbirths, miscarriages, mummies, weak litters, etc. But sows do not show symptoms; Symptoms: the fetus is absorbed when infected within 30 days; The appearance of mummified fetuses at 30-50 days of infection; Stillbirth at 50-60 days of infection; Miscarriage occurs at the time of infection at 70 days; 70 days later, the infection is accompanied by poisoned piglets; Diagnosis: detection of pathogens by immunofluorescence techniques; Hemagglutination inhibition test for antibodies.

Prevention: Immunization is the most effective measure by species.

4. Pig esophageal oral nematode disease: (1) that is, "nodular worm disease", which often occurs in intensive pig farms. (2) 2 Pathology: mainly parasitic in the colon, the larvae make the intestinal wall form nodular lesions, and the adults affect weight gain and feed transformation. (3) Prevention: For soil-derived parasites, environmental sanitation is the most important. (4) 4 Treatment: Left mi.

5. Pig nephrocosis: (1) it is a "toothed coronyx", which is caused by parasitizing the renal pelvis, perrenal fat and ureter of pigs. (2) 2 form: the insect body is thick, shaped like a matchstick, and the fresh insect body is gray-brown. (3) Route of infection: through the mouth and skin, pigs in southern China mostly occur in March to May and September to November. (4) Symptoms: skin inflammation, anemia, claudication, flocculent and pus in the urine. (5) Diagnosis: post-microscopic examination of insect eggs in morning urine, or discovery of insect bodies during autopsy. (6) Chemotherapy: levamisole, albendazole
