Micro elements levels in the milk of horses and donkeys in Croatia

The concentrations of micro elements Al, Co, Cr, Li, Mo, Ni, Sb and Sr in the milk of Croatian Coldblood horse and Littoral-Dinaric donkey were determined by inductively coupled plasma-optical emission spectrometry. The total mean element contents in horse milk were (g/kg): Al < 10, Co < 10, Cr 27.3, Li 4.98, Mo 12.1, Ni < 10, Sb 67.2 and Sr 495.5. Variation of Li, Sb and Sr concentrations were found throughout the lactation stages (days: 10, 40, 60, 120, 180). In donkey milk, the mean element contents were (g/kg): Al < 10, Co < 10, Cr 26.1, Li 8.39, Mo 8.98, Ni < 10, Sb 24.1 and Sr 560.4. Correlations were found among elements in horse and donkey milk. Significant differences in concentrations of Li and Sb between two species were determined. Other elements concentrations were similar in both species. Very limited data are available on the micro element content of Al, Cr, Co, Li, Mo, Ni, Sb and Sr in horse and donkey milk in general. To our knowledge there is a first report on these micro ele¬ments content in milk of these two species in Croatia.
