Different Factors Effects In Lactating Mother's Milk Compositions

Abstract

This study was carried to estimate the effects of different factors on the total protein and lipid concentrations in lactating mother's milk, such as; home, age, body mass index, lactating stage and negative smoking habitat. Total Protein concentration and lipid concentration were estimated using Bradford method and Gravimetric method respectively. Results showed that lipid concentration(L.C) increased with age,  BMI, lactation stage, and affected by  negative smoking and increased in rural,  while protein concentration (P.C)was less effected by age, and decreased in obese and in negative smoking mothers, also it decreased in urban mothers. Protein profile showed slight differences between nonsmoking and negative smoking milk using SDS-PAGE electrophoresis.

Key words: negative smoking, BMI, lactating mother’s milk.
