Abstract:
Weaning rats were divided into three groups. The first group were fed on a synthetic diet deficient in riboflavin. The second group were fed on the same diet but supplemented with riboflavin, and the quantity of the ration was limited to that of the paired animal in the first group. The third group were also on the riboflavin supplemented diet, but fed ad libitum.It was found that anorexia rapidly developed in the deficient animals and thus caused retardation of growth. However, the appetite was quickly restored as soon as riboflavin was supplied. From the results obtained with the pair feeding method, the growth of the deficient animal is somewhat less than the paired control.There was no effect of riboflavin deficiency on nitrogen equilibrium of the rats and on storage of protein in the liver. There was a slight decrease of ammonia nitrogen excretion in the urine during riboflavin deficiency. Slight increase of urinary amino nitrogen was observed only in the early stage of deficiency.
