Prevention and treatment of pig dysentery poisoning
Dysentery is often used to treat gastrointestinal infectious diseases, such as porcine paratyphoid and so on.
The dosage of pigs is 0.007 grams per kilogram of body weight, which is taken orally for 2 to 3 times. Son pigs are more sensitive to dysentery, which can cause acute or chronic poisoning when fed too much or used for a long time. After poisoning, the pig lost appetite, weak limbs, unstable standing, walking swaying, front and back limbs extended outward, skin temperature decreased, slow response, coma, muscle trembling all over the body. After autopsy, it was found that there was severe inflammation in the gastric fundus mucosa of the dead pigs. there was a strip of inflamed area from the pylorus through the gastric fundus to the cardia, and there were a small number of bleeding spots of different sizes, and the intestinal contents were golden.
The disease should pay attention to prevention, can not be long-term or excessive feeding of such drugs, a course of treatment is about 1 week. When pigs are poisoned, they should immediately stop feeding medicated feed and give laxative drugs to speed up the excretion of poisons; feeding 2% sugar water (brown sugar and white sugar) has a good effect on relieving symptoms. For severe pigs, 5% sugar saline can be injected intraperitoneally or intravenously, and other drugs can be added according to the actual situation.

Changes of Antibody to Porcine Circovirus Type 2
There were two peaks of antibodies against porcine circovirus, one was maternal antibody at 1~2 weeks of age, the other was maternal antibody at 8~10 weeks of age, which was caused by circovirus infection, and then the antibody level decreased to undetectable at the stage of big pig, which also indicated that the virus infection was slight at this stage. Porcine circovirus infection is very harmful to pigs. The period of low health level of pigs coincides with circovirus infection in time. This is our strict prevention against immune failure and secondary infection.
