ABSTRACT.
The article presents data on the content of iron and lactoferrin in the breast milk of Orenburg women,
obtained as a result of a pilot study in this region. Thus, the iron content was 0.930±0.056 mg/l. The average concentration of LF was 1.39±0.18 g/l, which corresponds to literature data (0.99 to 3.39 g/l). Considering the relevance of the
research, it is necessary to conduct a broader study of breast milk from Orenburg women at different stages of lactation
to obtain regional reference values for iron and lactoferrin.
KEYWORDS: Iron, lactoferrin, breast milk.
