For previous work see Absts. 6303, Vol. 30; 986, Vol. 31. Results are tabulated of 77 N balance studies on 12 infants during the first 6 months of life. Olac, a commercial preparation of fat-free milk, maize oil and dextrimaltose was the food of 4 infants, 3 were fed on evaporated milk and water and 5 on homogenized whole cow's milk. The diets provided 20% of total energy as protein. Vitamins and Fe were given but no other food. Growth of the infants during the first 6 months was considered to be normal. The results of the balance studies and estimations of concentration of total and urea N in serum in this and the previous studies of infants on lower intakes of protein are discussed. Total N in serum was similar for the 3 diets and was not higher than was previously recorded for infants with lower intakes of protein. Mean concentration of urea N in serum was positively related to intake of protein. Retention of N from selected diets increased with increasing N intake in the first 5 months of life until intakes of 800 to 900 mg per kg were reached. N was retained better from Olac than from the other diets. Calculation of the protein content of the body of an infant from the results of N retention gave a result which was considered to be falsely high. Possible reasons for this are considered. F. C.
