Growth performance of male broilers fed ExPress® soybean meal and high-shear dry extruded corn

Soybean meal ( SBM ), a co-product of soybean oil obtained via solvent or mechanical extrusion, is the key protein source in broiler diet formulations. Mechanical high-temperature processing with high-shear dry has demonstrated 1 to 2% increased amino acid digestibility broilers versus solvent-extracted through reduction antinutritional factors ANF ). High-shear extrusion followed by pressing using screw press (extruding-pressing) produces soy and partially de-oiled soymeal (ExPress). The extruding-pressing process been growing popularity due improved cost material efficiency eliminating need for solvents steam dryers production animal feed ingredients. Corn likewise linked nutritive value palatability approximately 20% starch gelatinization, resulting superior growth performance one reported case, reduced mortality broilers. In present study, extruded corn ExPress were formulated combination conventional determine impact on male Extruded intake weight gain. containing outperformed all other combinations, including unprocessed, ground conventional, variations. had most efficient overall conversion ratio FCR lower observed ingredient reflected made this ideal formulation, out 4 diets examined, terms efficiency.
