The present study evaluated the productive characteristics, nutrient digestibility, and economic indexes of broiler chickens submitted to diets containing different nutritional levels, and identified advantages for the commercialization of poultry in the griller-type whole chicken model. A total of 180 COBB 500 chicks ™ were distributed in a completely randomized design, in a 2x3 factorial scheme: sex (male and female) and nutritional level (nutritional requirements for male, female or mixed flock); with 6 repetitions of 5 birds each. It was observed effect of the sex factor in the performance and the economic analysis, in which the male chickens presented the highest feed costs, in spite of exhibiting the best feed conversion rates and gross marketability, resulting from greater body weight. Considering nutritional levels, the most outstanding diet was that formulated according to the demands of the females, which did not affect the performance or carcass characteristics of the birds, obtained the highest gross margins with good feeding costs, showed good retention of dry matter and gross energy, regardless of sex. The diet of nutritional requirements of the females provides promising results for the production of broiler chickens. The female birds present marketing advantages in the griller-type chicken model.
