Using adapted for Muscovy ducks balance experiments (fecal methods), the AME and TME and the true digestibility of the amino acids of brewery wastes have been established. The zero nitrogen balance AME of the fodder were 5,0 and the TME - 6,69 MJ/kg DM. The true digestibility coefficients of the amino acids varied from 64,4% (lysine) to 96,58% (glycine). [BG].
