Concentration of phosphorous (P), potassium (K), sodium (Na), magnesium (Mg), calcium (Ca), iron (Fe), zinc (Zn), copper (Cu), and manganese (Mn) was determined in the kidney tissue of sixty-nine pigs belonging to ten different genetic lines of pigs, produced in Vojvodina (northern Serbia). Phosphorous was determined by the standard spectrophotometric method. Metals were determined by the flame atomic absorption spectrometry after mineralization by dry ashing. The order of the minerals in the kidney tissue and their content ranges in mg/100 g was P (246–347, on average 287) > K (142–236, on average 189) > Na (102–187, on average 130) > Mg (17.8–36.6, on average 23.3) > Ca (15.9–27.7, on average 20.2) > Fe (5.32–10.42, on average 7.42) > Zn (2.15–4.10, on average 2.99) > Cu (0.62–2.15, on average 1.29) > Mn (0.16–0.30, on average 0.22). Genetic lines of pigs had no influence on mineral concentrations of kidney (P>0.05). The Vojvodian pig kidney showed slightly lower K, slightly higher P and Mn, and higher Ca contents, compared to the values reported in the literature.
