^a-bMean values within a row with the same superscript letters were not significantly different (P < 0.05)
¹AGP represents the data from broilers fed antibiotic growth promoters, and GOD-P and GOD-A represent the data from broilers fed GOD produced by Aspergillus niger and Penicillium amagasakiense, respectively
²SEM: Standard errors of the mean
