The Elusieve process, a combination of sieving and elutriation (air classification), has been found to be effective in separating fiber from ground corn, distillers dried grains with solubles (DDGS), and soybean meal (SBM). The objective of this study was to determine the effect of removing fiber from ground corn, DDGS, and SBM on broiler live performance during the 42-d experimental period and assess the economic effect. A total of 6 dietary treatments were evaluated in which 3 treatments incorporated an additional nonstarch polysaccharide (NSP) enzyme corresponding to the following 3 treatments: regular diet, direct substituted enhanced diet, and an isocaloric, isonitrogenous enhanced diet. The study consisted of 48 pens with 45 male broiler chicks per pen. Elusieve processing increased starch content of corn by 7.8% and increased protein content of DDGS and SBM by 2.3 and 0.9%, respectively. Enhanced diets resulted in birds with 4.6 to 5.0% higher BW gain, higher breast weight by 7.1 to 11.3% and feed conversion improvement by 4 to 6 percentage points (2.4 to 3.2%) compared with regular diet. There was no effect of NSP enzyme on performance and feed consumption. Interaction effect (between NSP enzyme and dietary type) was observed only in 2 of a total of 12 performance indicators. The increase in profit due to implementation of the Elusieve process in a 1,000 t/d feed mill is estimated to be $0.5 to 2.5 million/yr, which is 0.8 to 4.3 cents/bird produced. The payback period is estimated to be 0.9 to 4.7 yr.
