A total of 280 straight-run broiler chicks were used to evaluate the feeding value of insect-protected herbicide-tolerant corn. Birds were randomly distributed into four treatments following a completely randomized design. Treatments included were diets with commercial corn, insect-protected herbicide-tolerant corn, insect-protected corn and herbicide-tolerant corn. The results show that the ME content of genetically-modified(GM) corn and commercial corn used in this study were not statistically different. However, birds fed diets with the commercial corn performed better than those fed diets with GM corn. Birds fed diets with any of the GM corn – insect-protected, herbicide-tolerant or combined traits of insect-protected and herbicide-tolerant corn – elicited similar growth and efficiency on feed utilization. The carcass yield and organoleptic characteristics of cooked broiler meat, except for tenderness were, were likewise similar in all groups. Results indicate that the feeding value of insect-protected herbicide-tolerant corn was equivalent to any of the single trait GM corn, though slightly lower compared to the commercial corn.
