¹OB = oat bran; DIM = digestibility index marker; Cr₂O₃ = chromic oxide; TiO₂ = titanium dioxide; DIM recovery is the ratio of digestibility index marker amount in feces and feed during the total collection of feces period.

² n = number of observations; it includes 3- and 5-d duration of feces collection.

³Duration of feces collection refers total collection of feces for either 3 or 5 d after a 7-d adaptation.

⁴The P values for all the interactions including OB level, DIM level, duration of feces collection, or DIM type are all >0.10, and the P values are not presented.
