Brief Project Summary:
The proposed research will estimate the productive energy value of SBM in a large-scale commercial swine research facility in the middle and end of the growing period. This will provide insight into how pigs utilize energy in SBM under commercial conditions and will generate an energy estimate to be used for diet formulation. Incorrect energy utilization assumptions have economic consequences making this work very relevant for the swine industry. If the energy value of SBM is greater than the published theoretical values, producers will be incented to use more SBM in their diets while energy prices remain elevated.

Progress Of Work

Final Project Results

This work was completed to determine productive energy value of soybean meal (SBM). The current methodology of estimating SBM energy value using NRC (2012) ME values as a reference and adjusting for chemical composition of samples collected from batches of soybean meal prior to initiation of the study using published prediction equations (Noblet and Perez, 1993) suggested SBM ME would be 94.1% relative to corn ME. Four different levels of SBM inclusion were evaluated over 2 different growing periods with diets formulated to constant SID Lys:ME using an assumption of 94.1% SBM ME relative to corn ME. In both periods, ADG and ADFI were similar between treatments but feed efficiency improved linearly as SBM level increased. The linear improvements in feed efficiency suggested a SBM ME value relative to corn of 101.7% and 104.7% in the early and late feeding periods, respectively, which were both higher than the assumed 94.1% SBM ME value relative to corn ME. These results suggest that U.S. swine producers have opportunities to revise formulation assumptions to better capture the full value of SBM.

Benefit To Soybean Farmers

This work suggest that U.S. swine producers may have been underestimating the energy value of SBM. Increasing our assumptions for the productive energy value of SBM has the potential to increase SBM utilization by swine producers, depending on commodity price relationships. Increased utilization of SBM by swine producers has the potential to increase overall SBM demand and support soybean prices.

The United Soybean Research Retention policy will display final reports with the project once completed but working files will be purged after three years. And financial information after seven years.
