The use of computerized mathematical growth models to estimate accurate and profitable dietary amino acid needs for broilers is a promising alternative to use of fixed requirements. Estimation of crude protein needs by the OmniPro® II growth model is higher than minimum CP levels known to support maximum broiler performance. In this experiment, male broilers were fed either a series of diets formulated using OmniPro® estimations for total amino acids and CP, or a series of diets formulated to provide from 90 to 105% of amino acids estimations made by OmniPro without a CP minimum. Results indicated that diets formulated based on OmniPro total amino acid estimations, with or without minimum crude protein constraints, supported the best live performance and carcass traits.
