Two studies are reported in which chicks were fed from hatching, purified, vitamin E-free diets containing no added antioxidants for 6 to 12 months. Chemical analyses indicated that {alpha}-tocopherol disappeared from the tissues of the chicks after 5 weeks. When compared with control chicks receiving vitamin E, the depleted chicks appeared normal, grew at the same rate and layed eggs at the same time. The possible tocopherol content of the diet, and the implications of these results on the nutritional and biochemical functions of vitamin E, are discussed.

1 Preliminary reports of portions of this study have been presented before the Poultry Science Association, 1956 annual meeting (Briggs et al., '56) and before the American Institute of Nutrition, 23rd annual meeting: Bieri, J. G., and G. M. Briggs 1959 Non-essentiality of vitamin E for normal growth and development of the chick. Federation Proc., 18: 517 (abstract).
