The Effect of Transport Stress on Erythrocyte Glutathione Peroxidase Activity, Plasma Concentrations of Lipid Peroxidation and Some Trace Element Levels in Beef Cattle

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 +/- 2.0-9.67 +/- 1.1 IU g(-1) Hb) and increase in plasma lipid peroxidations concentrations (from 1.627 +/- 0.14-2.196 +/- 0.26 nmol mL(-1)) were found in cattle exposed to transport stress. These differences were not statistically different. In addition; transport stress caused significant (p<0.01) decreases in the levels of zinc (from 2.034 +/- 0.15-1.503 +/- 0.05 mu g mL(-1) cupper(from 1.608 +/- 0.095-1.330 +/- 0.072 mu g mL(-1)) and increase in the levels of iron (from 1.60 +/- 0.136-2.05 +/- 0.125 mu g mL(-1)). Transport stress did not affect Magnesium levels.
