OTA – ochratoxin A; BSFE – Bacillus subtilis fermentation extract; RTD – renal tubular degeneration; RTN – renal tubular necrosis; RTP – renal tubular proliferation. Data are presented as median (n = 7 microscopic field/5 sections representing 5 birds/group). Different letters in the same column indicate a significant difference at P < 0.05
