^a,b,cDifferent superscripts within a row indicate evidence for difference (P < 0.05) in fecal DM.

¹A total of 300 weaned pigs (Line 241 × 600, DNA Genetics, Columbus, NE) with an initial BW of 4.83 kg and 18.5 d of age were used. Pigs were allotted to pens in a completely randomized design with 5 pigs per pen and 10 replicates per treatment.

²Common period in which all pigs fed the same diet without feed additives from d 25 to d 46.

³Three pigs per pen were randomly selected and sampled. The fecal samples were collected from the same pigs and dried.
