The effect of variation in the calorie. Protein ratio of the diet on nitrogen retention and body composition in the rat.

In view of the fact that the
calorie : protein ratio profoundly influences growth and N retention, certain adjustments
may be expected to occur in some tissues. In the work now described, the
relationship between the calorie content of the diet and growth and N retention has
been studied by ascertaining the effects on carcass, liver and plasma constituents of
changes in the calorie : protein ratio in casein diets which either contained equal
quantities of protein or were isocaloric, the calorie : protein ratio being modified by
the inclusion of cellulose or by increasing the fat or protein content.
