Problems solved by technology

[0003] How to solve the porcine epidemic diarrhea that is prevalent in the current pig industry is an important problem. Chinese herbal medicine has become a new favorite of feed additives due to its advantages of non-toxicity, no side effects, and strong drug resistance. But now most of them use a single Chinese herbal medicine, which has a single effect. Drug resistance is single; in order to achieve the purpose of preventing diseases, Chinese herbal medicines are used directly, and their usage is relatively large, which affects the taste of feed, and the quality indicators are difficult to control
