A 4 × 3 factorial experiment (n=8 pigs per treatment combination) was conducted with 96 female Landrace × Large White pigs to examine the required level of dietary vitamin E and optimum feeding duration before slaughter to maximise muscle vitamin E content in the Longissimus thoracis et lumborum (LTL) muscle. The respective factors were four dietary levels of vitamin E (supplemented as dl-α-tocopheryl acetate; 35, 300, 500, and 700 IU/kg) and three feeding durations (14, 28 and 42 days before slaughter). Vitamin E concentration in the LTL was maximised at 6 mg/kg, which was achieved by feeding a 700 IU vitamin E diet for 28 days before slaughter (P<0.001). There was no further increase in the vitamin E content of the LTL by feeding the high vitamin E diet more than 28 days before slaughter.
用96头长白猪×大白猪杂交的雌性猪进行了一项4×3析因试验（每个处理组合8头猪），以研究日粮中维生素E的所需水平以及屠宰前的最佳饲喂持续时间，从而使胸腰最长肌（LTL）中的肌肉维生素E含量最大化。各因素分别为四种维生素E日粮水平（以dl-α-生育酚醋酸酯形式添加；35、300、500和700 IU/kg）和三种饲喂持续时间（屠宰前14、28和42天）。LTL中的维生素E浓度在6 mg/kg时达到最大值，这是通过在屠宰前28天饲喂700 IU维生素E日粮实现的（P<0.001）。在屠宰前28天以上饲喂高维生素E日粮，LTL中的维生素E含量没有进一步增加。
