Daily dietary nutrient intake in the four nutritional groups.

	ENT n = 11	IL n = 12	SMOF n = 11	EXP n = 11
Protein (g/kg)	13	13	13	13

These values are based on published ingredient compositions of formula and TPN solutions, with the exception of lipid composition which was measured directly as described below in methods. Commercial preterm infant formula (Enfamil Premature 24 Cal, Mead Johnson Nutrition). The infant formula contains the following sources of protein (60% whey, 40% casein), carbohydrate (60% corn syrup solids, 40% lactose), and fat (40% MCT oil, 30% soy oil, 27% high oleic vegetable oil, 3% single-cell oil blend rich in docosahexaenoic acid, DHA and arachidonic acid, ARA). The infant formula was fortified with whey protein, lactose and DHA to match the macronutrient and DHA level in SMOFlipid group. Electrolytes and micronutrients also were matched to the intake of the SMOFlipid group.
