The Effect of Riboflavin and Biotin in the Prevention of Dermatitis and Perosis in Turkey Poults

THE various reports in the literature are in fairly good agreement on the amount of riboflavin needed by the turkey poult for maximum growth. On the other hand, there is wide disagreement concerning some of the deficiency symptoms in poults resulting from a lack of this vitamin. The results obtained by Heuser (1935) using a riboflavin deficient diet composed largely of practical ingredients, showed that a lack of riboflavin resulted principally in reduced growth. No evidence of dermatitis was mentioned. Lepkovsky and Jukes (1936) reported that turkey poults fed either a diet composed of natural ingredients low in riboflavin or a purified riboflavin-deficient diet failed to grow, suffered high mortality, and developed dermatitis. They found that a supplement of a purified riboflavin concentrate prevented the above symptoms. Jukes (1938) confirmed the findings of Lepkovsky and Jukes (1936), and found that a whey adsorbate rich in riboflavin gave good growth and . . .
