Colostrum samples from four warm-blood mares (in three repetitions) were analysed 2, 12, 24, 36, 48 and 72 hours postpartum. The samples were obtained by hand milking. Calcium, phosphorus, magnesium, sodium, potassium, zinc, copper, iron and manganese concentrations were analysed in each sample. Non-significant decreases of postpartum Ca and Na conc. were found in the analysed samples. Significant differences in P conc. were detected between 2 and 36 hours postpartum. Mg conc. showed significant differences during the period after foaling (2, 24, 36, 48 and 72 hours post foaling). Mg conc. reached its maximum (21.8 g/kg of dry matter) 2 hours postpartum and it dropped to its lowest level (5.27 g/kg of dry matter) 48 hours after foaling. Similarly, the highest K conc. (significant in relation to values obtained 36, 48 and 72 hours postpartum) was detected 2 hours after foaling while the lowest K level (37.96 g/kg of dry matter) was found 48 hours postpartum. As regards the microelements, Cu showed insignificant differences in its postpartum levels, Fe levels increased, whereas those of Zn and Mn decreased.
