Soybean meal is the dominant protein supplement used in poultry diets and is the standard to which alternative protein sources are compared. Soybeans can be fed to poultry whole or as soybean meal, a by-product of oil extraction. Soybean meal has a high protein content, especially when compared to other plant protein sources. Soybean meal also has an excellent amino acid profile that complements that of corn, the primary energy source in poultry diets.
