Abstract

The lactose, total nitrogen and total lipid contents of human breast milk were determined longitudinally after protein and term deliveries. Milk samples were obtained from day 2 to 5, on weeks 1, 2, 4, and 6 after preform (PM: n=24) and term (TM: n=22) deliveries. The lactose contents of PM and TM increased from 5.28 g/dl and 5.93 g/dl at days 2 to 5, to 7.95 g/dl,7.87 g/dl at 6 weeks, respectively. The total nitrogen contents of PM and TM decreased significantly during the first 6 weeks after birth (from 374 to 220 mg/dl versus 382 to 220 mg/dl respectively). However the total lipid contents of the PM and TM increased during the same periods. Significant differences in the total lipid contents between the PM and TM were 2.15 versus 3.27 g/dl at 2 weeks, and 3.26 versus 2.52 g/dl at 6 weeks, respectively. The energy intakes of preform infants was 134.8 kcal/kg/d during the 6 weeks of lactation, which satisfied with energy requirements (85-130 kcal/kg/d) of the preform infants.
