. Plasma enteroglucagon, pancreatic polypeptide, gastrin, motilin, neurotensin, gastric inhibitory polypeptide, secretin, vasoactive intestinal peptide and blood glucose, alamine, ketone bodies, lactate and pyruvate were measured on the sixth postnatal day in ( a ) a group of 10 preterm infants who on account of hyaline membrane disease had not received enteral feeding since birth and ( b ) before and at 55, 90, and 120 minutes after feeding in a group of healthy preterm infants fed three‐hourly on human milk. Gut hormones were also measured in umbilical venous cord blood. The infants receiving regular boluses of milk from birth demonstrated postnatal surges in preprandial concentrations of gut hormones together with cyclical hormonal responses to feeding. None of these changes were seen in infants receiving intravenous fluids. The latter infants also had lower concentrations of blood alanine, glycerol and hydroxybutyrate and lacked the phasic changes in intermediary metabolites seen in the infants receiving enteral boluses of milk. Thus deprivation of enteral feeding results in a profound alteration of the metabolic and endocrine milieu which may have important effect on the process of adaptation to postnatal life.
