Abstract
Dietary alpha-tocopheryl acetate promoted growth and protected against death due to acute CCl4 toxicity in young rats reared on diets with 10% protein furnished either by casein or soybean meal. Vit. B12 supplements, alone, had a similar effect although 30 [mu]g-% in the soybean diet was needed for protection against CCl4 while 3 [mu]g-% was enough for growth promotion. Folacin alone was without benefit. All 3 were necessary for best growth. Cystine also protected against the CCl4 toxicity.
