Changes of Antibody to Porcine Circovirus Type 2
The porcine circovirus antibody has a certain stage, and the antibody has two peaks, one is the maternal antibody obtained from the mother at the age of 1-2 weeks, and the other is caused by circovirus infection at the age of 8-10 weeks, and then to the pig stage, the antibody level decreases to undetectable, which also indicates that the infection of the virus is mild at this stage. Porcine circovirus infection does great harm to pigs, and the period of low health level of pigs coincides with circovirus infection in time, which provides a theoretical basis for immune failure, serious secondary infection and the increase of respiratory problems in pigs, and also provides a new way for us to prevent and control the epidemic.

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. When the dead pigs were examined, it was found that the gastric fundus mucosa had severe inflammation.

Goose dysentery poisoning
Furazolidone is also called furazolidone. It is a common intestinal antimicrobial agent in veterinary clinic. The safety index of the drug is low, especially sensitive to poultry, and its therapeutic dose is closer to that of poisoning. Geese are often poisoned by overdose. Clinically, it is mainly seen in young geese and often causes death after poisoning. 1. Etiology (1) the prevention dose of dysentery commonly used in geese with excessive dosage or uneven mixing is 100m / kg 200 mg / kg feed, and the therapeutic dose is 300m / kg / kg feed.
