Histopathological changes in cecal tissues from chickens. Typical histopathological changes in the ceca, including severe damage to intestinal villi and intestinal glands in the lamina propria, were observed in the IC control (F) and LD groups (C). The HC group (D) and the DC group (E) showed no obvious histopathological changes. The histopathological changes in the HD group (A) and the MD group (B) were not as severe as those in the IC group (F). Mucosal integrity can be found in the B and D sections. Arrow shows intestinal villi and intestinal glands. Scale bar = 100 µm
