Modifications in Soybean Seed Composition to Enhance Animal Feed Use and Value : Moving From a Dietary Ingredient to a Functional Dietary Component

Abstract

Animal feed is the primary user of the nonoil component of soybeans. Breeding and gene modification strategies have been successfully employed to alter the seed composition of soybeans in a manner that enhances their use in animal feeds. Examples include altering amino acid profiles, fatty acid composition, oligosaccharide removal, and most notably phytic acid reduction. Such enhancements are required if soybeans are to maintain their use level in animal feeding applications. As advancements in genetic modification continue, an even greater level of animal feed applications will ensue through development of soybeans that have antimicrobial, health, and biogeni properties. Thus, soybeans in the future may not be produced as much for use as a protein feedstuff or as a source of oil, but rather for their ability to promote beneficial physiological properties or to enhance food safety.
