The Nutrition of the Mouse

Abstract
The riboflavin requirement of 2 highly inbred strains of mice has been studied by measuring growth rates at various dietary levels of the vitamin after a 1-week depletion period. Mice of the C57 strain showed maximal growth under the conditions of these experiments when the diet contained 0.4 mg of riboflavin per 100 gm, while the A strain required a dietary level of 0.6 mg. At an 0.2 mg level C57 mice had lowered red cell counts and muscle and liver riboflavin content, while the A strain showed no such difference.
