Compare the nutritional status of essential minerals in milk of different cattle and humans: Estimated daily intake for children

Abstract In present study, the comparisons of electrolytes, calcium (Ca), potassium (K), magnesium (Mg), sodium (Na) phosphorus (P), and essential trace elements, iron (Fe), zinc (Zn), copper (Cu) and selenium (Se) were carried out in milk samples of different cattle (cow, buffalo, goat, sheep, and camel) and human as total and soluble form (whey of milk). The sampling of milk was carried out from different farms, flocks and human from rural areas of Hyderabad city. The electrolytes and essential trace elements in milk, as total and soluble (whey) forms were determined by different techniques, after acid digestion method. The concentrations of Na, K Ca, P and Mg were significantly higher in camel milk, whereas, the contents of K were elevated in goat and sheep milk. As compared to the different cattle, human milk had the lowest concentrations of all selected essential trace elements except Se. The percentages of all elements in whey milk were found in the range of 20 to ≥ 95 % of their total contents in whole milk samples of different cattle and human. The estimated daily intake of all elements was calculated for infants
