“…The two infant formulae were commercial, 0e6 months, whey dominant, premium infant formulae. The b-serum (Fletcher, Catchpole, Grey, & Pritchard, 2006) and buttermilk protein concentrate (BPC50; Catchpole, Tallon, Grey, Fletcher, & Fletcher, 2008) samples were proprietary products manufactured by Fonterra Co-operative Group Ltd.
