Three experiments were conducted to determine
standardized ileal digestibility (SID) of AA (Exp. 1), concentration
of DE and ME (Exp. 2), and standardized total
tract digestibility (STTD) of P (Exp. 3) in DFB and 2
hydrolyzed porcine intestinal mucosa products (PEP50
and PEP2+), and compare these values with values for
fish meal
