Conditioning and expansion increase nutritional value of soybean expellers

Soybean expellers contain trypsin inhibitors, which negatively affect nutrient digestibility, feed efficiency, and health status of animals. Therefore, heat treatment is needed to inactivate trypsin inhibitors to improve nutrient digestibility in soybean expellers. Different types and degrees of processing conditions may influence digestibility of energy and amino acids (AA) in soybean expellers, but there is a lack of data demonstrating how long heat treatment is needed if soybean expellers are expander processed after hydrothermical conditioning. Therefore, 2 experiments were conducted to test the hypothesis that the standardized ileal digestibility (SID) of AA, as well as values for digestible energy (DE) and metabolizable energy (ME) in soybean expellers increase the longer heat is applied to the expellers.

Digestibility of energy, and total dietary fiber, and concentration of digestible and metabolizable energy in soybean expeller and soybean meal fed to growing pigs

When soybeans are crushed, the oil may be solvent extracted and the resulting defatted soybeans are known as soybean meal (SBM). However, the oil may also be mechanically expelled from the beans and the defatted soybeans resulting from this procedure is an ingredient known as soybean expellers. The expelling procedure is less efficient in removing oil from the beans and soybean expellers, therefore, contain more residual oil than SBM. Soybean expellers can be produced using different technologies, and a new procedure involving a patented high shear dry extrusion procedure was recently developed (Insta-Pro International, Des Moines, IA). There are however, no data for the apparent total tract digestibility (ATTD) of GE and total dietary fiber (TDF) and DE and ME concentrations in the soybean expellers that are produced from this procedure. Therefore, the objective of this research was to test the hypothesis that the ATTD of GE and TDF and concentrations of DE and ME are greater in soybean expellers than in SBM when fed to growing pigs.

Digestibility of amino acids is greater in soybean expellers than in soybean meal when fed to growing pigs

When soybeans are crushed, the oil may be solvent extracted and the resulting defatted soybeans are known as soybean meal (SBM). However, the oil may also be mechanically expelled from the beans and the defatted soybeans resulting from this procedure is an ingredient known as soybean expellers. The expelling procedure is less efficient in removing oil from the beans and soybean expellers, therefore, contain more residual oil than SBM. Soybean expellers can be produced using different technologies, and a new procedure involving a patented high shear dry extrusion procedure was recently developed (Insta-Pro International, Des Moines, IA). There are however, no data for the digestibility of amino acids (AA) in the soybean expellers that are produced from this procedure. Therefore, the objective of this research was to test the hypothesis that the standardized ileal digestibility (SID) of crude protein (CP) and AAis greater in soybean expellers than in SBM when fed to growing pigs.
