Intakes of key nutrients from typical enriched post-discharge feedings for preterm infants, assuming milk intake of 160 mL/kg per day

Intakes of key nutrients from typical enriched post-discharge feedings for preterm infants, assuming milk intake of 160 mL/kg per day
Feeding strategy Breastfeeding (or bottle feeding with expressed breast milk) Formula
Strategy for enrichment Breast milk × 6 feeds
- and -
premature discharge formula[1,2] (22 kcal/oz) × 2 feeds		 Breast milk × 5 feeds
- and -
premature discharge formula[1,2] (22 kcal/oz) × 3 feeds		 Breast milk × 6 feeds
- and -
premature formula[3] (30 kcal/oz) × 2 feeds		 Premature discharge formula (22 kcal/oz)
Energy (kcal/kg/day) 112 113 120 117
Protein (g/kg/day) 1.9 2.2 2.3 3.4
Calcium (mg/kg/day) 59 to 64 70 to 76 94 to 100 125 to 144
Phosphorus (mg/kg/day) 34 to 35 41 to 42 49 to 56 74 to 80
This table uses the following assumptions:
  • Feeding intake is 160 mL/kg/day.
  • Breast milk provides 20 kcal/oz with 0.9 g/dL of protein.[4]
For infants who are less than 44 weeks gestational age, a liquid formulation of premature discharge formula[1,2] or premature formula[3] should be used rather than a powdered formulation. Nutrient composition of these formulas are based upon commonly used commercial brands, as cited.
