We believe that rendered meals such as chicken meal, turkey meal, or lamb meal provide a very good economical source of concentrated protein, but we feel that dehydrated chicken is even better. RAWZ uses only dehydrated chicken as our natural concentrated protein source. Our dehydrated chicken comes from USDA and FSIS approved chicken and has a higher P.E.R. Value (Protein Efficiency Ratio) than rendered meals. It is gently cooked at much lower temperatures, which helps retain protein and amino acids, keeping the protein in a more natural state.
