Twelve crossbred wethers, four per diet, were allotted at random as follows: (1) purified control diet; (2) purified diet plus a weekly oral dose of 1 mg sodium selenite per sheep; (3) purified diet plus a weekly oral dose of 1000 l.U. vitamin E. The wethers were maintained on the diets for six months. Weight gains during the initial 140 days of the experiment were significantly greater in selenium (Se)-supplemental sheep than in the others. The rumem liquor from the untreated sheep contained lower proportions (molar %) of acetic acid than from the Se or vitamin E-supplemented sheep and had higher butyric acid concentration than the Se-supplemented sheep. Concentrations of acetate, butyrate and valerate were higher in vitamin E than in Se-supplemented sheep. In addition, the concentration and molar percent of isovaleric acid was significantly higher in Se-supplemented sheep than in the other sheep.
12只杂交阉羊，每种日粮4只，随机分配如下：(1) 纯化对照日粮；(2) 纯化日粮加每只羊每周口服1毫克亚硒酸钠；(3) 纯化日粮加每只羊每周口服1000国际单位维生素E。阉羊按这些日粮饲养6个月。在实验的最初140天里，补充硒（Se）的绵羊体重增加显著高于其他绵羊。未处理绵羊的瘤胃液中乙酸比例（摩尔%）低于补充硒或维生素E的绵羊，丁酸浓度高于补充硒的绵羊。维生素E组的乙酸、丁酸和戊酸浓度高于补充硒的绵羊。此外，补充硒的绵羊中异戊酸的浓度和摩尔百分比显著高于其他绵羊。
