The results obtained point out the occurrence of malnutrition in these newborns who have lower levels of plasma albumin than controls, high indexes of malnutrition from plasma aminograms and lower urinary excretion of histidine and its N-methyl derivatives. All indexes are normalized at 7 days of life with the used diet.
