¹AID = apparent ileal digestibility; OB = oat bran; DIM = digestibility index marker; Cr₂O₃ = chromic oxide; TiO₂ = titanium dioxide; n = number of observations.

²The P values for interactions including OB level × DIM level, OB level × DIM type, DIM level × DIM type, and OB level × DIM level × DIM type are all >0.10, and the P values are not presented.
