Italian research compared the nutritional value for broilers of insect-protected (Bt) corn containing the Cry1A(b) protein (MON 810) with near-isogenic control corn varieties. Diets were formulated to meet the chick nutrient requirements and to contain about 50% corn. The data supported the conclusion that performance of broilers fed Bt corn was at least as good as those fed the isogenic conventional corn lines.
