The modern broilers have undergone extensive genetic selection, which allows them to be robust, productive, and efficient.  As a result, the modern broilers require advanced nutrition to achieve their genetic potential.  The energy and balanced protein are the two most influential nutrients that affect the growth performance of broilers.  The goals of selecting the combination of energy and balanced protein should rely on optimizing growth performance, but more importantly, economic benefits.  Likewise, the modern breeders also possess similar characteristics to the broilers; thus, they require a comprehensive feeding and nutrition.  Lysine control and energy dilution are two of the main strategies to support proper frame and body composition, adequate feathering, maximum egg production, and hatchability.  Overall, advanced nutrition and feeding must be part of broiler and breeder production to achieve optimum performance.
