[Nitrogen metabolic indices of infants fed a new milk mixture].

The efficacy of utilization of the protein compound from Ladushka, a new formula mixture, was studied in infants of the first 6 months of life, starting from the neonatal period. The protein component of the mixture consisted of casein and decalcified whey proteins (1:1). Calcium content comprised 400 mg/l, and its ratio with phosphorus approached the values recommended for formula feeding. The mass volumes of accessible lysine and cystine, despite additional enrichment of the mixture with these amino acids, were considerably reduced versus the expected values, that may be explained by insufficiently sparing technology of preparation.
