Summary and Implications
Data from this analysis suggest that differences in chemical composition likely exist when comparing conventional and GMO corn stover. However, the myriad of brands, hybrids, and trait combinations that exist highlight that more controlled plot-based studies need to be conducted, focusing on trait variation within a single corn isoline as to determine individual trait effects on these potential differences in feeding value.
