ResumoIN AGREEMENT with Sunde and Bird (1957), we have found that young Ringnecked pheasants receiving certain practical rations often develop a high incidence of leg disorders, especially when reared in batteries with wire mesh floors. Sunde and Bird (1957) found that the addition of 20 mg. of niacin per kg. of a basal practical ration decreased the incidence of leg disorders in young pheasants from approximately 50–70% in those receiving the basal diet to about 10% in the supplemented groups. Further supplementation of the diet with alpha-tocopheryl acetate and an antioxidant caused a somewhat further decrease in the incidence of leg disorders, but did not completely prevent the leg abnormalities. Niacin has been known for some time to be required for prevention of perosis or an enlarged hock disorder in turkeys, ducks and geese (Briggs, 1946; Jukes et al., 1947; Scott, 1953; Scott and Heuser, 1952; and Briggs et …
