Nutrient retention in preterm infants fed standard infant formulas . Our purpose was to compare nitrogen , mineral , and zinc balance in preterm infants fed standard infant formulas , Similac With Iron and Similac With Whey + Iron . Nitrogen and magnesium balances were similar during both feeds , and met estimated fetal requirements . Infants absorbed and retained ( milligrams per kilogram per day ) more calcium , phosphorus , and zinc when fed Similac With Iron . However , retention of calcium , phosphorus ( both formulas ) , and zinc ( Similac With Whey + Iron ) was inadequate to meet estimated fetal requirements . These findings are important in the rapidly growing preterm infant , who is already at risk for the development of rickets and zinc deficiency and may be fed either formula on discharge from the newborn nursery .
