Effect of Increased Enteral Protein on Body Composition of Preterm Infants

To increase protein content of human milk, a fixed amount of commercially available hydrolyzed bovine protein will be added to fortified human milk. With this pragmatic approach, preterm infants assigned to the high protein supplementation group will receive \> 4.5 g/kg/day of enteral protein after establishment of full enteral feeding.

Infants assigned to the standard protein supplementation group will receive fortified human milk (\< 4.5 g/kg/day of enteral protein)
