Feeding studies were conducted with rats and broiler chickens to assess the safety nutrition of maize grain containing event DP-Ø23211-2 (DP23211), a newly developed trait-pyramid product for corn rootworm management. Diets 50% ground from DP23211, non-transgenic control, or reference hybrids (P0928, P0993, P1105) fed Crl:CD®(SD) 90 days. Ross 708 broilers phase diets up 67% each source 42 Body weight, gain, feed conversion determined comparisons between animals DP23211 control in study. Additional measures included clinical neurobehavioral evaluations, ophthalmology, pathology, organ weights, gross microscopic pathology rats, carcass parts select yields broilers. Reference groups determine if any observed significant differences likely due natural variation. No diet-related effects on mortality evaluation animal produced grain. These show that is as safe nutritious grains when nutritionally adequate diets. The results are consistent previously published studies, providing further demonstration absence hazards edible-fraction consumption genetically modified plants.
