¹Data are means of 3 batches of each feed, each batch was tested in triplicate.

²PBBC: Bacillus subtilis var. natto N21 + Bacillus coagulans L12 fermented feed was dried by oven at 65°C for 7.5 h, and then pelleted.

^a,bMean in the row with different superscripts are significantly different (P < 0.05).
