Broiler chickens were used to compare broiler performance fed YieldGard ® and YieldGard® x Roundup-Ready® corn lines. The starter diet contained 50% test-corn and the finisher diet that was fed day 20-42 contained 60% test-corn. Four of the eight treatments consisted of conventional corn varieties. Results indicated that there were no biologically relevant difference in performance, carcass yield and meat composition between the broilers fed the various corn lines.
