The swine fever is the source of all diseases. The factors that generally affect the effectiveness of vaccines are as follows. Please pay attention to:
1, its own quality problems, not vacuum packaging, it is recommended to buy from the big factory.
2. There are too many transportation links, and they are not well-preserved (chain goods, down seedlings, it is best to purchase them from regular channels).
3, sun exposure lead to failure, to avoid light.
4, the temperature is too high during transportation, be sure to freeze preservation.
5, needle, needle is not clean, please choose a one-time needle.
6, cross-infection of sick pigs (a needle hit the end).
7, when the pig is not healthy (diarrhea, cough blue ear, ring, etc.) to do the epidemic.
8. Dilutions use boiled water and mineral water. It is recommended to dilute with fresh water.
9. The dilution temperature exceeds 30 degrees, especially in the summer.
10. After the dilution, it was not used up within 3 hours. The number of swine fever virus strains decreased.
11. There was antiviral western medicine in the feed within 3 days before and after epidemic prevention.
12. Preemptive immunity does not generally have good results.
13. It is not possible to prevent blue-ear disease or immunosuppressive vaccines within a week or so.
14. Insufficient dose during epidemic prevention.
15, pregnant sows can do swine fever vaccine.
We recommend that you purchase swine fever vaccine from large manufacturers and scientifically formulate epidemic prevention procedures. Before the epidemic prevention, it is best to use mixed-sensing brakes (pure Chinese medicine preparations) for 7-10 days to regulate the overall immunity of the herd. New bifurcation (transfer factor) dilutes the vaccine, relieves immunosuppression, rapidly produces antibodies, and avoids immunization gaps. Reduce the risk of vaccines.
