26 healthy full-term infants were fed, from birth, on Similac Isomil (a dried soya bean formula), 29 were fed Lactogen (a modified liquid milk formula) and 26 were breast fed. At the end of the 6-month trial, 24 infants were still receiving Isomil, 35 were receiving Lactogen (including 9 cases where breast feeding failed early in the trial) and 6 infants were still being breast fed. All infants made satisfactory growth and neurological development, regardless of type of feeding. Blood haemoglobin and all biochemical data were normal, and the only significant difference between the groups was in blood urea N level; breast-fed infants had a lower level (P < 0.001) than had either of the artificially-fed groups, and, after the 1st month, Isomil-fed infants had a lower level (P < 0.01) than had Lactogen-fed infants. It is concluded that Isomil compares very favourably with Lactogen and may be fed to infants who cannot tolerate formulae based on cows' milk; it may, however, cause some peri-anal irritation during the 1st 2 wk of life.
