2. What should I pay attention to when using pig spleen drenching vaccine and "unknown high fever inactivated vaccine" to prevent pig diseases? Some pig farms are effective and some are ineffective.

In fact, it is better to cross-use spleen drench vaccine and cell vaccine in pig farms, which can make up for the defects of these two kinds of vaccines. The effect of this immunization is related to the quality of the vaccine you use and the vaccination procedure. Quality is sometimes inevitable, but the program can be adjusted.

And "nameless high fever" is actually a mixed infection, which can't be a disease. It is caused by a variety of pathogens. It can be said that it is not effective to make your own vaccine to prevent "nameless high fever". In fact, the main factor of high fever is that the immunity of pigs is too poor, and there is no formal prevention and treatment of blood diseases. When the immunity is low, almost all vaccines fail, so the main problem is that you must improve the immunity level of pigs. This depends on the usual health care, and the health care effect of choosing Chinese medicine depends on antibiotics. But at present, there are many Chinese medicines and veterinary drugs on the market, which are really rare but expensive, so it is very important to choose this Chinese medicine manufacturer, and their post-service is better.

I hope my answer can give you some advice,
