This study concerns the effects of one week of total intravenous feeding on rats. Two age groups were examined. Such parenteral feeding resulted in reduction of the mass of the small and large intestine. The villi of the ileum were thinner and packed closer together but the active transport of 14C valine per villus was the same in the orally and in the intravenously fed rats. The younger animals showed significant enlargement of the adrenal glands and also enlargement of heart and kidneys suggesting work hypertrophy of these organs.
