    Abstract:
    In the former report on he calcium requirement in Small-for Date (S-f-D) infants it was observed that the ability of calcium absorption of S-f-D infants is lowered in 1-st semester of life. From this point of view it seemed purposeful to study the influence of 3 modified cow's milk formulas (see table) on the calcium absorption in S-f-D infants. Modification of these diets in regard to cow's milk depended on: 1) partial replacement of cow's milk fat with soya oil. 2) change of the proportion between fat and protein. 3) partial replacement of milk casein with lactoalbumin . The infants were divided into 3 groups G, H and C according to the kind of diet. Observation in the first 2 groups lasted for the whole first year of life, C group of infants was observed only in 1-st half year of life. In the first month of life G and H infants were fed the same unmodified cow's milk formulas (diet S) 3-day balance-studies. Were carried out once a month. The data of these 3 groups of infants were compared with each other and the data of S-f-D infants fed unmodified cow's milk formulas (group S) described in he former report. In group S, calcium intake was the highest in 1-st and in 2-nd semester of life among all compared infant groups, but the difference was not statistically significant. The lowest (%) absorption was noted in group G infants (fig. 2, table III and IV). The difference was statistically significant in 1-st semester of life between group G and S and in 2-nd semester between G and S as well as G and H groups. Calcium retention mg/kg was also the lowest in group G infants, and the difference was statistically significant in 1-st and in 2-nd semester between G and S groups. The infants fed H formula in spite of the lowest indices of calcium absorption % and retention mg/kg in the first (see table) and the second month of life and in spite of the lowest intake of calcium among all compared infants groups cough up absorption (%) and retention (mg/kg b.w.) with groups S in 2 semester of life.(ABSTRACT TRUNCATED AT 400 WORDS)
