Soybean meal is the product of extracting soybean oil by chemical method, and oil residue makes soybean cake low. The products produced by oil plants are generally puffed, and the protein content of first-class soybean meal is 46%, and that of second-class soybean meal is 43%.

Soybean cake is the product of mechanical pressing to extract soybean oil. Residual oil makes soybean meal higher and has higher relative energy. With the different pressing processes, the protein content is unstable, the highest is 43%, and the maturity is not complete, so it needs to be ripened according to the situation.
