Abstract
Comparative data from basal rations containing dextrin and sucrose, respectively, show that no dermatitis resulted when the former was used, whereas a high incidence of dermatitis resulted when sucrose served as the basal carbohydrate. Vitamin B and lactoflavin supplementing the sucrose ration did not prevent the development of dermatitis, nor did these supplements permit normal and continued growth; such supplements fed with dextrin promoted a substantial rate of growth. A concentrate prepared from rice polish cured the dermatitis occurring in the sucrose fed animals and at the same time promoted a substantial rate of growth, provided adequate amounts of vitamin B and lactoflavin were fed simultaneously. The occurrence of dermatitis was delayed and not as regular with a sucrose ration containing 10 per cent hydrogenated vegetable oil as with one containing 3 per cent of the same oil. The data as a whole would seem to indicate that the basal ration containing 69 parts of sucrose and 3 parts of hydrogenated vegetable oil is well suited for the determination of the growth-promoting properties of lactoflavin, provided that it is supplemented with adequate amounts of vitamin B and the vitamin factor or group of factors contained in the rice polish concentrate.
