All values for the treatment groups are given in grams per kilogram.

^aDietary treatment groups: A, hydrolyzed soy/collagen; B, whey protein concentrate; C, hydrolyzed whey protein concentrate + casein.

^bSignificant hydrolysis, but not as much as the hydrolyzed whey protein concentrate + casein.

^cPrimarily intact protein.

^d50/50 mixture of whey protein and casein that is heavily hydrolyzed by enzymatic digestion followed by filtration; contains ∼60% free amino acids, ∼33% <500D peptides, and no peptides >3 kDa.

^eThe following L-amino acids were added as grams per kilogram: tyrosine, 3.8; leucine, 3.4; valine, 3.3; isoleucine, 2.5; phenylalanine, 2.4; histidine (HCL) monohydrate, 2.0; methionine, 1.7; tryptophan, 0.62; and threonine, 0.97.

^fMaltodextrins from corn with a dextrose equivalent of 10–15 (150–451 g/kg).

^gAIN-76 Mineral mix, Harlan Teklad 79055, Madison, WI. Ammonium paramolybdate, Tetrahydrate was added at 0.7 g/kg diet.
