Vitamin Bc, Inositol, and Nicotinic Acid in the Nutrition of the Turkey

Abstract
The amount of pteroylglutamic acid required by the turkey poult for maximum growth and normal development is approximately 0.2 mg %. Under our experimental conditions the addition of inositol had no appreciable effect on either growth or the differential leucocyte count. When inositol was omitted from the diet the number of leucocytes was subnormal. The incidence of perosis in turkey poults was decreased by increasing the nicotinic acid content of the diet from 5 to 10 mg %. Perosis was never completely absent in spite of the fact that the rations contained all factors known at present to prevent it.
