This study was conducted to determining the GPX, Hemoglobin concentration (Hb) and hematocrite percentage (Hct) in blood samples of young ewes were gathered at different places of Zagheh Salman pastures in Qom province. 15 blood samples were gathered through 8 flocks during autumn, winter and spring seasons randomly. At first the measures of GPX, Hb and Hct were determined and then GPX concentration in the basis of unit per gram of hemoglobin and unit per milliliter of hematocrite were calculated. Data were analyzed using SPSS software. Results showed that the ratios of GPX to hemoglobin concentration (GPXlHb) and hematocrite percentage (GPX/Hct) were higher than their marginal levels significantly. There were significant differences between three seasons for hematocrite percentage and the ratios of GPX to hemoglobin (GPXlHb) and hematocrite (GPXlHct).The mean of hematocpte percentage had a maximum level in spring and minimum in winter. The ratios of GPX to hemoglobin and hematocrite had a maximum level in autumn and minimum in spring. The results of this research indicate that, despite of differences between flock and seasons all of flock had higher amounts of mentioned blood factors than their marginal levels and they had no deficiency aspects for these blood factors.
