Effects of dietary aflatoxin B1 (AFB1) and marine algal polysaccharides (MAPs) on histological changes of the bursa of Fabricius in broilers. (A) Control group, basal diet without addition of MAPs and AFB1; (B) AFB1 group, basal diet with addition of 100 μg/kg AFB1; (C) AFB1 + MAPs group, basal diet with addition of 100 μg/kg AFB1 and 2,500 mg/kg MAPs. The bursa of Fabricius sections were stained with hematoxylin and eosin. The scar bar is 50 μm of 200 × and 25 μm of 400×.
