    Abstract: This study was performed to investigate, the effect of transport on erythrocyte glutathione peroxidase activity, plasma lipid peroxidations concentrations and some mineral substances levels in feedlot beef cattle. The study material consisted of male beef cattle (n = 30; 1-2 years old), transported from Adana to Sanliurfa. Blood samples were taken before and after transport. Decrease in erythrocyte glutathione peroxidase activity (from 12.70&plusmn;2.0-9.67&plusmn;1.1 IU g<SUP>-1</SUP> Hb) and increase in plasma lipid peroxidations concentrations (from 1.627&plusmn;0.14-2.196&plusmn;0.26 nmol mL<SUP>-1</SUP>) were found in cattle exposed to transport stress. These differences were not statistically different. In addition; transport stress caused significant (p&lt;0.01) decreases in the levels of zinc (from 2.034&plusmn;0.15-1.503&plusmn;0.05 &#956;g mL<SUP>-1</SUP>), cupper (from 1.608&plusmn;0.095-1.330&plusmn;0.072 &#956;g mL<SUP>-1</SUP>) and increase in the levels of iron (from 1.60&plusmn;0.136-2.05&plusmn;0.125 &#956;g mL<SUP>-1</SUP>). Transport stress did not affect Magnesium levels.
