↵^aEnough casein and red meat were added to reach a total protein content of 15% for the low protein diets and 30% for the high protein diets.
↵^bLard was added to the casein and low red meat diets to balance each diet for saturated fat and to give a total fat content of 20%.
↵^cAIN-76 vitamin and mineral mixtures with modified calcium at 0.5 mg/g, phosphorus at 3.6 mg/g, folic acid at 0.23 μg/g, and vitamin D3 at 0.11 IU/g.
