  • Particle size | Hans H. Stein

    Particle size is an important consideration for some feed ingredients in pig diets. Reducing the particle size of cereal grains and soybean meal in diets fed to pigs improves digestibility of energy, amino acids, and other nutrients, because feed ground to smaller particle sizes has more surface area on which digestive enzymes can work.
