The document discusses nutrition for preterm and congenitally small infants. It notes that preterm infants have high nutritional needs for optimal growth. Early minimal enteral feeding can provide advantages like faster weight gain and shorter hospital stays compared to parenteral nutrition alone. Breast milk is preferable to preterm formula due to beneficial components, though formula provides more calories, proteins and minerals. The study assessed the effectiveness of different nutrition methods in 30 preterm and small infants, finding that a combination of preterm formula and breast milk was most effective for growth.
