[The effect of food supplements on the bioavailability of breast milk for premature infants--fecal fat and carbohydrate excretion]. / Der Einfluss von Nahrungssupplementen auf die Bioverfügbarkeit der Frauenmilch für Frühgeborene. Die faecale Fett und Kohlenhydratexkretion.

Faecal excretion of fat and carbohydrates was studied in 14 preterm infants fed on raw mother's milk (group I) or banked fortified human milk (group II) at days 7, 14, 21 and 28 of postnatal life: group I: n = 5; 31.0 +/- 2.0 weeks; 1954 +/- 441 g; group II: n = 9; 32.0 +/- 1.0 weeks; 1806 +/- 176 g. Mixtures of amino acids, peptides, minerals, dextrine and maltose were designed for fortifying banked human milk. There were no significant differences between faecal excretion of fat and carbohydrates in both feeding groups. The investigated human milk fortifier helps to realize the protein-energy ratio needed in preterm infants with well tolerable volumes of feeding and without stressing their limited digestive capacity.
