Nonidentical twin male infants (twin 1, 950 g birth weight, twin 2 970 g) had their nutritional and hormone status studied for up to 59 days. Both infants received parenteral nutrition up to 32 days postnatally; enteral feeding was then established in twin 1; in twin 2 parenteral feeding was recommenced on day 35, for the remainder of the study. Serial 72‐hr metabolic balances were performed in both infants at 4, 32, 45, and 56 days postnatally. Insulin‐like growth factor I (IGF‐I) and growth hormone were assayed on day 2 of each balance. During the course of the study growth was similar in each infant. Overall mean daily energy intakes were 90 kcal/ kg/day and 84 kcal/kg/day and percentage nitrogen retention was 62% and 55% in twin 1 and twin 2, respectively. No differences were observed between the two infants in IGF‐I or growth hormone. Despite low energy intakes incremental weights were within an acceptable range for both infants.
