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. Pathogeny
The main results are as follows: (1) the prevention dose of dysentery commonly used in geese with excessive dosage or uneven mixing is 100Mel 200mg / kg feed, and the therapeutic dose is 300Mel 400mg / kg feed. According to clinical observation, 1 gram per kilogram of feed can cause goose dysentery poisoning. Similarly, the uneven use of medicine and mixture will also lead to excessive dosage of goose clothing and cause poisoning.
(2) if the continuous administration time is too long, the excretion of dysentery into the goose is slow, which takes about a week. Although the dosage of dysentery is small, it can also cause cumulative poisoning because it has been used for more than a week.
two。 The clinical symptoms of goose dysentery poisoning are mostly acute. The poisoned goose has unstable gait, dyskinesia, neck twisting, reverse angular arch, and sometimes chirps constantly. Severe cases often die within a few minutes after poisoning. Those who have the ability to grow and develop slowly.
3. There were no characteristic pathological changes in this disease. Autopsy showed yellowish mucus (the color of dysentery) in the mouth, esophagus, glandular stomach, myogastric and duodenum, congestion, bleeding, hepatomegaly and congestion in the intestinal mucosa. Sometimes there are bleeding spots in the epicardium and effusion in the abdominal cavity with a long course of disease.

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.
