 The objective of this study was to compare the nutritional performance of 00000 maize grain to nontransgenic maize grain in a 00-d feeding trial in broiler chickens . Diets were prepared using grain from untreated 00000 plants and from plants treated with an in-field application of herbicides ( 00000 + Spray ) . For comparison , additional diets were produced with maize grain obtained from the nontransgenic near-isogenic control ( control ) and nontransgenic commercial reference Pioneer brand hybrids 00J00 , 00P00 , and 00R00 . Diets were fed to Ross x Cobb broilers ( n = 000/group , 00% male and 00% female ) in 0 phases : starter , grower , and finisher containing 00 . 0 , 00 , and 00 . 0% maize grain , respectively . No statistically significant differences were observed in mortality , growth performance variables , or carcass and organ yields between broilers consuming diets produced with maize grains from unsprayed or sprayed 00000 and those consuming diets produced with near-isogenic control maize grain . Additionally , all performance and carcass variables from control , 00000 , and 00000 + Spray test maize treatment groups were within tolerance intervals constructed using data from reference maize groups .

Based on these results , it was concluded that 00000 maize grain ( unsprayed or sprayed with a herbicide mixture ) was nutritionally equivalent to nontransgenic control maize with comparable genetic background .
