Aquaculture has become a significant producer of healthy protein for a growing world population, and manufactured feeds have been a key driver of success. As aquaculture expands into the future, formulation of feeds made from sustainable ingredients that support rapid growth yet produce healthy, strong animals in high intensity culture will be essential. Poultry require higher levels of macrominerals and lower levels of microminerals in their diets. The microminerals include copper, iodine, iron, manganese, selenium, and zinc. Although poultry have lower requirements for microminerals, these minerals play essential roles in the body’s metabolism.
