Resumo: This study aimed to evaluate the mineral composition of solid residues (SR) from desalination waste (DWSR), saline water (SWSR) and aquaculture ponds (APSR), and to discuss the results based on ruminant requirements. Mineral determined were K, P, Ca, Mg, S, Cu, Fe, Mn, Zn, Na, Cl, Ni, Pb, Cd and Cr, from 24 samples, 4 DWSR, 10 SWSR and 10 APSR, with three replicates. Desalination waste solid residue, SWSR and APSR had large variation of minerals. Saline water solid residue and DWSR presented potential to be used as source of Na and Cl, while the APSR can contribute Ca. All examined saline sources were poor in P, Ca and trace minerals except the APSR, showing a considerable concentration of Ca. Some samples of SWSR and APSR presented mineral concentrations that may be potentially toxic to ruminants.
