The effects of full-fat extruded soybean at different temperatures (FES) on performance of broiler chickens were evaluated in this trial. Isonutritive diets were formulated to meet broiler requirements in the growing (22 - 35 days old) and finishing (36 - 45 days old) phases. The experimental treatments consisted of four soybean extrusion temperatures (125, 130, 135 and 140ºC) with nine replicates of 30 birds. The variables investigated were: feed intake, weight gain, feed:gain ratio and carcass composition (leg yield, breast meat yield and abdominal fat). In both phases, no significant effect of the treatments on the variables was detected. Soybean extruded at temperature of 125 to 140ºC can be used in broiler chickens diets after 22 days old.
