Summary
Corn gluten meal (CGM) is a by-product of the wet milling corn. It is the residue that remains after the bran, germ and starch have been removed and may contain either 41 or 60% crude protein. There is a temptation to use CGM as an alternative to soybean meal (SBM) when the cost of SBM is high. The 60% protein CGM contains a greater quantity of protein and more threonine, sulfur amino acids, and other neutral amino acids than 44% protein SBM. However, SBM contains greater amounts of lysine and tryptophan. Previous studies with growing and finishing swine indicated that tryptophan is limiting in diets containing CGM, even though the diets were formulated to meet the requirements for tryptophan established by the NRC (1988). The objective of this study was to determine if feed intake is maintained for 10 to 20 kg pigs fed low protein diets containing CGM if crystalline L-lysine-HCL (L-LYS) is added to meet the lysine requirement.
