Energy assimilation in Pept1+/+ and Pept1−/− animals on low-protein (LP = 8% energy from protein), control (C = 21% energy from protein) or high-protein (HP = 45% energy from protein) diet.

The given values are the sum of the 5 day lasting feeding trial. Energy calculations of Pept1+/+ and Pept1−/− animals on low-protein (8% protein energy), control (21% protein energy) and high-protein (45% protein energy) diet for 5 days were analyzed (n = 10). Data are presented as sum of energy intake, energy excretion and energy assimilation over 5 days of feeding the diets.
