Ingredient composition of diets required for the study (g/100 g).

Component1	BF	SF	HF
Energy, kJ	2097	2084	2,110
Protein, g	14.62	14.4	14.56
Carbohydrate, g	51.96	51.82	53.8
Fat, g	25.83	25.9	25.63

BF, basal infant formula; SF, standard premature infant formula; HF, hydrolyzed protein formula.

¹All values were measured. Gross energy was measured by an Isothermal Automatic Heat Meter (5E-AC8018, Kaide Automatic Equipment Changsha Co., Ltd., Changsha, China). Crude protein (method GB/T 6432–1994), Fat (method GB/T 14772–2008), carbohydrate (method GB/T 5009.7–2016) were determined.
