The next generation of biotechnology-derived products with the combined benefit of herbicide toleranceand insect protection (MON 88017) was developed to withstand feeding damage caused by thecoleopteran pest corn rootworm and over-the-top applications of glyphosate, the active ingredient inRoundup herbicides. As a part of a larger safety and characterization assessment, MON 88017 wasgrown under field conditions at geographically diverse locations within the United States and Argentinaduring the 2002 and 2003-2004 field seasons, respectively, along with a near-isogenic control andother conventional corn hybrids for compositional assessment. Field trials were conducted using arandomized complete block design with three replication blocks at each site. Corn forage sampleswere harvested at the late dough/early dent stage, ground, and analyzed for the concentration ofproximate constituents, fibers, and minerals. Samples of mature grain were harvested, ground, andanalyzed for the concentration of proximate constituents, fiber, minerals, amino acids, fatty acids,vitamins, antinutrients, and secondary metabolites. The results showed that the forage and grainfrom MON 88017 are compositionally equivalent to forage and grain from control and conventionalcorn hybrids.
