MECHANISM OF ADAPTATION TO A TREONINE-DEFICIENT DIET. IV. EFFECT OF AGE AND WEIGHT ON THREONINE DEFICIENCY SYMPTOMS IN THE RAT

Abstract

When weanling rats are fed a threonine-deficient diet, fat deposits in the livers reach a maximum in approximately 2 weeks. This phase is followed by a period of recovery wherein the concentration of fat is slowly decreased. Livers from all rats fed casein diets deficient in threonine had significantly greater concentrations of fat than did the control animals. These differences were sig nificant at the 1% level regardless of the length of the ''pre-experimental feeding trial.'' However, the absolute amount of fat deposited in livers from rats fed a threonine-deficient diet decreased as the length of the pellet-feeding phase increased. The same trend, though on a much smaller scale, was observed in the control rats.
