Effect of fiber removal from ground corn, distillers dried grains with solubles and soybean meal using the Elusieve process on broiler performance and processing yield. Journal of Applied Poultry Research. 22(2):177-189.

Interpretive Summary: The Elusieve process, a combination of sieving and elutriation (air classification), has been found to be effective in fiber separation 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 impact. A total of six dietary treatments were evaluated in which three treatments incorporated an additional non-starch polysaccharide (NSP) enzyme corresponding to the following three treatments: regular diet, direct substituted enhanced diet and an iso-caloric, iso-nitrogenous 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. Elusieve processing decreased NDF content of corn, DDGS and SBM by 5.2, 3.4 and 1.4%, respectively. Chicks fed enhanced diets had improved performance compared to regular diets. Enhanced diets resulted in birds with 4.6 to 5.0% higher body weight gain, higher breast weight by 7.1 to 11.3% and feed conversion improvement by 4 to 6 points (2.4 to 3.2%) compared to regular diet. There was no effect on carcass yield. There was no effect of NSP enzyme on performance and feed consumption. Interaction effect between NSP enzyme and dietary type) was observed only in two performance indicators of a total of 12 indicators. The profit due to implementation of Elusieve process in a 1,000 ton/d feed mill is estimated to be $0.5 to 2.5 million/yr, which is 0.8 to 4.3 ¢ per bird produced. The payback period is estimated to be 0.9 to 4.7 yr.
