The sheep industry in Brazil is an important economic activity, and with the increasing global demand for sheep meat there is a great interest in the monitoring of the herd health, and serum reference ranges are basic tools for veterinary clinical pathology assays. Mineral elements correspond to 2-5.5% of the body of vertebrates, holding different functions in their physiology. The objective of this study was to obtain reference intervals of the electrolytes magnesium, phosphorus, chloride and calcium for the Dorper and Saint Ines sheep breeds. Sera samples were collected from 487 clinically healthy sheep, 146 from Dorper and 341 from Santa Ines breed. Electrolytes were measured using commercial kits. Data were analyzed taking the race, sex and age variables in account, and reference ranges were established. The results revealed significant statistical differences in reference ranges obtained for the electrolytes calcium and magnesium concerning the variable race, and for the electrolyte phosphorus in the variable age and, when compared with reference values already published, proved the existence of significant differences.
