GROWTH AND METABOLISM OF YOUNG HYPOPHYSECTOMIZED RATS FED BY STOMACH TUBE11,2

Abstract

Young rats, hypophysectomized and maintained by stomach-tube-feeding on a food intake which caused growth in littermate controls, lost slightly more fat and N in the feces, but intestinal absorption was good in all cases. Their skeletal growth was 10% of that of the controls, their N storage about 30%; they deaminated much more protein and stored more fat than the littermate controls, which accounted for their lower wt. in spite of a lower metabolic rate. The livers of the deficient rats did not vary in the same manner as the rest of the carcass, but reflected the mixture that was being burned; they contained less fat and as much or more protein than the livers of the controls.
