The requirements for fat-soluble vitamins A, D and E of the Japanese White Leghorn chicks were studied fed in purified diet. Effect of vitamin E supplementation to the corn-soy bean meal and sweet potato-soybean meal diets with 6.3 and 4.8% of animal fat was also studied for 4 weeks. Synthetic vitamin A palmitate, crystalline vitamin D_3 and d-α-tocopheryl acetate were used for standard vitamins. Body weight gains of chicks for 3 weeks suggested that the requirement of vitamin A was not more than that recommended by N.R.C., U.S.A., i.e. 2,650 I.U./kg diet. Results of tibia ash analysis revealed that the requirement of vitamin D was also not more than that recommended by the same, i.e. 200 I.C.U./kg diet. No positive effect was observed by the supplementation of vitamin E both to purified diet and natural diets.
