Particle Size in Swine Diets | The Pig Site

Reducing particle size of the grower-finisher from an average of 1000 microns to an average of 700 microns could save about $1.78 per pig per annum. An investment in a few particle size tests per year is well worth the effort, explains Greg Simpson, swine nutritionist with the Ontario Ministry of

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.
