Also, in vitro nitrogen (N) digestion
study was conducted with these samples using the two-step enzymatic method. The coefficient
of apparent ileal digestibility (CAID) of the SBM, independent of the origin, varied
from 0.820 to 0.880 for CP, 0.850 to 0.905 for lysine (Lys), 0.859 to 0.907 for methionine
(Met) and 0.664 to 0.750 for cysteine (Cys).
