The article presents chemical compositions of dairy products and milk from dairy cattle kept under different technological conditions, i.e. stable keeping at AE LLC Donskoye, Kalachevsky District, Volgograd Region and stall-camp keeping at JSC Kirov Farm, Staropoltavsky District, Volgograd Region. To determine chemical compositions, methods of inductively coupled plasma mass spectrometry (ICP-MS) and inductively coupled plasma atomic emission spectrometry (ICP-AES) were applied. There was used an Elan 9000 quadrupole mass spectrometer (Perkin Elmer, USA) and an Optima 2000 DV atomic emission spectrometer (Perkin Elmer, USA). The article also provides a comparative description of macro- and microelement compositions of samples (milk, sour cream, cream, whey, cottage cheese, and butter) and concentrations of heavy metals. The obtained results allowed a conclusion that stall keeping is preferable for obtaining high-quality dairy raw material because ruminants’ microflora in forestomachs cannot quickly adapt to summer pasture rations after winter stall keeping.
