Comparing Various Soybean Protein Products for Broilers

Researchers at the University of Arkansas compared the performance of broiler chicks fed either extruded full-fat soybean meal or dehulled solvent-extracted soybean meal. Soybeans were processed by passing the beans through a roller mill and then extruding without steam. The full-fat meal replaced 0, 25, 50, 75 or 100% of a commercially solvent-extracted soybean meal in nutritionally adequate broiler diets containing 3200, 3300 or 3400 kcal/kg metabolizable energy. Each treatment was fed to six replicated pens of 60 male chicks of a commercial broiler strain from 1 to 42 days. The results of the experiment demonstrated that the extruded full-fat soybean protein source in a pelleted broiler diet supported chick performance that was equal or superior to that of dehulled solvent-extracted soybean meal. Weight gains, feed conversion, mortality, dressing percentage, and abdominal fat content were similar for the two soybean protein sources.
