用18头3周龄左右的阉公猪，按3 × 3析因设计，研究不同水平维生素E和硒对组织和血液指标的影响。随着硒摄入量的增加，组织硒浓度以二次曲线的方式增加，肾组织中的硒浓度比肝脏、心脏或肌肉高得多。补充的饮食引起的血清硒在第一周内增加了三倍，在随后的几周内有进一步增加的轻微趋势。在实验期间，未补充维生素E的猪的血清维生素E下降了50%，而补充维生素E导致血清维生素E增加。过氧化氢溶血百分比有相当大的上升。维生素E摄入量与过氧化氢溶血率的相关性为-0.63，血清维生素E与过氧化氢溶血率的相关性为-0.85。
Eighteen barrows approximately three weeks of age were used in a 3 X 3 factorial arrangement to investigate the effect of level of supplemental vitamin E and selenium on tissue and blood parameters. Tissue selenium concentrations increased in a quadratic manner with increased selenium intake with kidney tissue containing considerably greater concentrations than liver, heart or muscle. Supplementation of the diet caused a three-fold increase in serum selenium within the first week with a slight tendency to further increases in subsequent weeks. Serum vitamin E of unsupplemented pigs declined by fifty percent during the experiment, whereas supplemental vitamin E resulted in increased serum vitamin E. There was a considerable viration in percent peroxide hemolysis. Correlation of -0.63 between percent peroxide hemolysis and vitamin E intake and -0.85 between percent peroxide hemolysis and serum vitamin E were observed.
