I run a veterinary medicine shop, and I want to enter the pig medicine industry. Which pig pharmaceutical factory is good?

There are 1600 veterinary drug factories in China. In order to adapt to the market, the products produced by various factories have both good and inferior drugs, as well as preventive and therapeutic drugs. If you want to take medicine, you'd better communicate with its technicians first to understand the real situation. If there are more than a few manufacturers, we must sell all the good drugs, the therapeutic drugs in case of epidemic, and the preventive drugs in case of no epidemic, otherwise there will be no competitive advantage.
