The aim of our research study was to determine the content of mineral elements in milk of Holstein, Jersey, Brown Swiss, Ayrshire, Norwegian-red, Swedish-red cows in the first stage of lactation. All cows were fed with the same type (composition) of feed and they were kept under the same condition. The concentration of macroelements (K, Na, Ca, P, Mg, S) in digested milk samples was determined by inductively coupled plasma optical emission spectrometry (ICP-OES).application/pdfcow milkmacroelementayrshirebrown-swissholsteinjerseynorwegian redswedish redfolyóiratcikkOpen Accesshttps://doi.org/10.34101/actaagrar/40/2700Acta Agraria Debreceniensis40Acta agrar.
