Extruded-Expelled Soybean Meal for Pigs

2000 University of Nebraska-Lincoln Extension Swine Report. A review of the value of extrudedexpelled soybean meal (ESBM) for pigs was conducted. Results from two studies where the growth performance of weanling pig was evaluated suggested that the feeding value of ESBM relative to solvent-extracted soybean meal (SSBM) is not consistent. The economic value of ESBM relative to SSBM was estimated from pig performance data and the metabolizable energy content of corn, ESBM, and SSBM. When ESBM is used to replace 44% CP SSBM in growing-finishing pig diets, it is worth 0 to $36.29 per ton more than 44% CP SSBM, assuming 44% CP SSBM and corn cost $175/ton and $2/bushel, respectively. When ESBM is used to replace 46.5% CP SSBM in growing-finishing pig diets, it is worth 0 to $18.45 per ton more than 46.5% CP SSBM, assuming 46.5% CP SSBM and corn cost $175/ton and $2/bushel, respectively. Due to the higher fat content of ESBM, there is less dust generated when ESBM is handled compared to SSBM. Caution should be exercised when considering the purchase of ESBM due to the apparent quality variation until further evaluations on ESBM are completed.
