Maize composition evaluation

The nutrients, anti-nutrients, and secondary metabolites listed in Table 1 were assessed as part of the composition evaluation of maize event NK603 (11). A total of 105 comparisons between NK603 and its non-transgenic control were conducted for U.S. sites in 1998 and the E. U. sites in 1999. The values for the biochemical components for com event NK603 were similar to the control or were within the published range observed for non-transgenic commercial com hybrids. 

The assessment of compositional equivalence, livestock nutritional performance, and safety in rodent feeding studies share many common features. All these studies involve test, control, and reference groups, a specified experimental design that involves randomization and replication, followed by data collection (measurements) and lastly, evaluation (statistics). The study plan for the compositional analysis of maize has been described in detail previously (11) and is summarized in Table 1. The maize test line (event NK603), the control line (a near isogenic parental hybrid), and reference lines (19 conventional, non-transgenic commercial hybrids) obtained from controlled field trials were included in the study. Field sites were located in two different geographic areas, the United States (U.S.) and the European Union (E.U.), over...
