Abstract： Feed accounts for 60% to 70% of costs in pig and poultry production. The technology of diversified diets with low protein and low soybean meal is critical to reduce feed costs and relieve the pressure on the supply of feed grains such as corn and soybean meal. Accurate nutritional values are the keystone to determine the substitutability of various feed ingredients and to formulate diversified diets with low protein and low soybean meal. To obtain accurate nutritional values for feedstuffs in practice，it is critical to establish dynamic nutritional value database for feed ingredients by developing precise and rapid evaluation technologies.Thereby，this article systemically discusses the importance and broad application of simulated digestion technique in nutritional evaluation for feedstufs from three aspects： the principles of establishing nutritional values database for feed ingredients，the progress in simulated digestion technique for feedstuff evaluation，and the application of simulated digestion technique in fedstuf database establishment and substitutability determination.
