Abstract Background: Very clinical cases of mineral deficiency, specially associated with copper in sheep of Khuzestan province have been annually seen; whereas the studies on soil and forage related mineral and effects of them on zonal domestic animals are rare. Objectives: The aim of the present study was to investigate the copper, sulfur, iron, molybdenum and zinc of soil and pastures forages status in order to see the probable correlation of these elements with copper and zinc serum of sheep in Susngerd town of Khuzestan province. Methods: 5 soil and forage samples and 50 blood samples from sheep that were grazing in the area were taken. All the samples were sent to the institute of radiation at atomic energy organization of Iran for the elements measurement. The soil samples were alkaline digested and read by ICP-OES apparatuses. After acidic digesting, forage samples were read by ICP-MS apparatuses. Serum levels of copper and zinc were also measured by atomic absorption spectroscopy. Results: The averages iron and sulfur content of soil were higher than international standard and critical levels, while the averages copper and molybdenum were within normal range. The mean of soil zinc in comparison to the crisis amounts was in the lower level (p= .05). Comparing the mean values of forage elements with their critical levels showed that sulfur and iron were higher than standard levels. The results revealed that the serum copper and zinc were lower than normal and sheep under this investigation were mostly in a borderline deficiency status. Conclusions: It seem that high levels of sulfur and iron in pastoral forages reduces intestinal absorption and bioavailability of copper and zinc in sheep grazing in the under study areas.
