Amino acid digestibility of a synthetic diet fed to mink

A synthetic diet has been designed with a protein fraction entirely made up by crystalline amino acids (Sandbol et al., 2007). The amino acid composition is based on the ideal protein concept (Sandbol et al., 2004). It is assumed that crystalline amino acids are 96% digestible. To confirm this hypothesis, a digestibility trial was conducted with the purpose to determine the apparent digestibility of the individual amino acids used in the diet.
