Abstract

An experiment was conducted to better understand the effect of the particle size on the enzyme digestion in pigs. Particle size has a great influence on starch digestibility. We now show that within single milled grain samples, individual particles show major differences in their enzyme digestion rates in vitro depending on their size. Enzyme digestibility is shown to be dependent on the abundance of slowly-digested large particles, by reducing the proportion of these larger particles greater enzyme digestibility is achieved.
