A cloudiness in the central portion of the lens was found in embryos from eggs laid by turkey hens reared on wire and fed an all-vegetable protein diet without added vit. E. Associated with the lens disorder was a hemorrhaged vitreous humor, a smaller embryo with edematous areas on the neck and feet, and a high embryonic mortality between the 24th and the 28th day of the incubation period. Supplementation of the all-vegetable protein diet with alpha tocopheryl acetate was effective in preventing the anomalous conditions described, while fish solubles, dried whey, or combinations of these substances had no effect.
