Two finishing trials were conducted to evaluate the effect of feeding corn root worm protected (Bt) and Roundup Ready® (RR) corn hybrids on animal performance and carcass characteristics in the feedlot. Two commercially available non-genetically engineered reference hybrids, and the nontransgenic control hybrid were compared to the two genetically enhanced hybrids. No significant differences were observed on animal performance or carcass characteristics for either trial as a result of corn source in feed.
