Removing fiber from corn could increase corn's nutritional value for non-ruminants (swine and poultry). In a previous study for fuel ethanol production, a simple combination of sieving and elutriation (air classification), called the Elusieve process, was found to be effective in separation of fiber from ground corn flour. The objectives of this study were to determine the effect of lighter fraction yields in air classification on composition and the effect of fiber separation on nutritional value of poultry diets. Fiber separation increased starch content in corn flour by 3.0% to 4.8%. Loss of starch in the fiber coproduct was higher as the lighter fraction yields increased. The body weight gain of chicks (21 d study) was increased, feed conversion ratio improved, and diet cost was slightly higher when fed an enhanced corn diet. To make a better comparison and to provide data for economic analysis, an additional study is needed in which birds are grown to slaughter age and diets are formulated with identical compositions except for the type of corn flour used.
