METABOLIC STUDIES OF NORMAL FULL-TERM INFANTS FED A PREPARED FORMULA PROVIDING INTERMEDIATE AMOUNTS OF PROTEIN


Abstract

<jats:p>Twelve normal full-term infants have been studied during ad libitum feeding of a prepared formula of cow's milk (Formula S) which provided an intake of protein intermediate between that of infants consuming human milk and that of infants receiving commonly employed formulas that supply two-thirds of the calories from cow's milk and one-third from additional carbohydrate.</jats:p>
<jats:p>Growth of the infants proceeded along normal developmental channels but, as in the case of infants fed human milk, the growth curves generally fell at or below the 50th percentiles of the Iowa Growth Charts. The studies were designed to compare nitrogen retention of groups of infants growing normally. Proper evaluation of growth of infants fed different foods would require larger numbers of infants in each group.</jats:p>
<jats:p>The mean concentrations of total protein and urea nitrogen in the serum were 5.3 gm/100 ml and 8.9 mg/100 ml, respectively.</jats:p>
<jats:p>The mean volume of intake was 198 mg/kg/day (providing 133 cal/kg/day) in metabolic balance studies performed during the first 1½ months of life and 142 ml/kg/day (providing 95 cal/kg/day) during similar studies performed between 4½ and 6 months of age. The mean intakes of nitrogen during the corresponding periods were 534 mg (= 3.3 gm protein) and 398 mg (= 2.5 gm protein)/kg/day, and the mean retentions of nitrogen were 211 and 102 mg/kg/day, respectively.</jats:p>
<jats:p>The retentions of nitrogen by infants ingesting Formula S ad libitum were as large as, or greater than, those of infants ingesting human milk ad libitum.</jats:p>
