What knowledge is needed for quality control of finished feed?

It is not easy to do anything well, especially quality control. The quality control of finished products should at least know the normal state and abnormality of finished products, the key points and common problems in the production process, the storage situation of finished products and the outbound situation. The storage and delivery here are different. You should pay attention to the inventory time of finished products and what your responsibilities are. Sometimes different units are responsible for the same work in time, and the scope and content of the work are different. I don't know exactly what you are responsible for, and some of them are hard to say.
