Detailed Explanation of the Patterns of Change in Porcine Circovirus Type 2 Antibodies
Porcine circovirus antibodies show a certain stage-based pattern, with two peaks. One occurs at 1 to 2 weeks of age and consists of maternal antibodies acquired from the mother; the other occurs at 8 to 10 weeks of age and is caused by circovirus infection. Then, in the older pig stage, antibody levels drop to undetectable, which also indicates that infection with the virus at this stage is relatively mild. Porcine circovirus infection is very harmful to pigs. The period when the health level of the herd is relatively low coincides in time with porcine circovirus infection, which provides a theoretical basis for us regarding immune failure, severe secondary infections,

What are the pathological changes of aflatoxin poisoning in pigs?
In acute cases, anemia and hemorrhage occur, with massive bleeding in the thoracic and abdominal cavities, and petechial spots often on the serous membrane surfaces. Hemorrhage occurs in the subcutaneous muscles in front of the thigh and under the scapula. The liver is enlarged with bleeding points. In the part of the liver adjacent to the serous membrane there are pinpoint or ecchymotic hemorrhages, obvious hemorrhages are common on the epicardium and endocardium, and hemorrhages are often present throughout the body muscles. In chronic cases, there is proliferation and sclerosis of the liver bile ducts, yellow fatty degeneration of the liver, white spots or necrotic lesions on the liver surface, and effusion in the thoracic and abdominal cavities. The renal cavity is pale and swollen. The systemic lymph nodes are congested and edematous.
