Micronizing is an infra-red cooking process used to improve the digestibility of grains for horses. A combination of moisture, heat and physical pressure is used to change the structure of starch (in a process known as gelatinization) and protein in the grains to improve their digestion in the horse’s small intestine. Grains digested in the horse’s small intestine provide the horse with greater nutritional value and don’t cause the diseases associated with grain overload into the hindgut.
