[Effect of ethoxyquin on the utilization of selenium in growing pigs].
In a 2 x 3 factorial arrangement with 30 male castrates (German Landrace; 13.7 +/- 1.7 kg b.w.), after a 2 week feeding period with a maize/torula yeast basal diet poor in selenium and without vitamin E supplementation, the effect of two ethoxiquin concentrations (0 and 150 mg/kg) und 3 selenium concentrations (0.075, 0.10 and 0.125 mg/kg) on growth, the activity of the Se dependent GSH-Px in the erythrocytes and the Se concentrations in liver, kidney, heart and diaphragm was measured after 4 weeks on the experimental diets. Under the experimental conditions chosen ethoxiquin had no effect of any of the parameters studied. Selenium supplementation significantly increased the enzyme activity and the Se concentrations in the organs and tissues analyzed.
