Abstract
Ca and P balance data in LBW infants fed four different formulas are shown below. Ca was determined by specific electrode and atomic absorption; P by a modification of Fiske-Subarow's method.
Ca retention correlated with intake (r=0.83 p 0.001) except for formula 3242 (r=0.55 p 0.05). The correlation between fecal Ca and fat malabsorption for V.I., Nan and S26 was significant (r=0.54 p 0.01). No correlation was found in formula 3242, surely due to its high MCT content and excellent absorption coefficient in all babies fed this formula.
P retention correlated with intake (r=0.94 p 0.001) in all formulas except S26 (r=0.57 p=NS). Fecal P excretion was 12.1 ± 6.7% on intake for every formula, but 3242 in which it was 28 ± 10.2% of intake. Retention varied within wide ranges 22 to 76.
