Phase feeding tailors swine diets to each physiological stage to match the animal’s changing nutrient needs for growth and efficiency. In the nursery, pigs grow rapidly and require high-quality protein and amino acids to support lean tissue development, so diets are high in protein. As pigs move into the growing-finishing phase, the focus shifts toward providing more energy and nutrients that support efficient gain, with protein needs relatively lower compared to energy density. This staged approach improves feed conversion and overall growth by aligning nutrient supply with the animal’s development. Diets aren’t kept constant across phases, and phase feeding is commonly used in swine production.
