Three groups of 10 pigs (6 to 8 weeks old) were fed a nutritionally complete ration (control ration, CR), CR plus 20,000 IU of vitamin E/ton (CR + recommended E), and CR plus 100,000 IU of vitamin E/ton (CR + high E), respectively. Each pig was given an intramuscular injection of an Escherichia coli bacterin at experimental days 0 and 35. Serums were collected 7 days prior to the first injection and at days 7, 14, 21, 35, 42, 49, and 56. Pigs fed the CR + high E ration developed anti-E coli serum antibody titers two- to threefold higher than those of the controls. Pigs fed the CR + recommended E ration developed serum antibody titers intermediate between those of pigs in the other 2 groups.
将三组10头猪（6至8周龄）分别喂以营养完全的日粮（对照日粮，CR）、每吨添加20,000国际单位维生素E的CR日粮（CR + 推荐量的维生素E）和每吨添加100,000国际单位维生素E的CR日粮（CR + 高剂量维生素E）。在实验第0天和第35天，每头猪都接受了一次大肠杆菌菌苗的肌肉注射。在第一次注射前7天以及第7、14、21、35、42、49和56天采集血清。饲喂CR + 高剂量维生素E日粮的猪产生的抗大肠杆菌血清抗体效价比对照组高两到三倍。饲喂CR + 推荐量维生素E日粮的猪产生的血清抗体效价介于其他两组猪之间。
