title: Scanning electron microscopy of intestinal villous structures and their putative relation to digestion and absorption in chickens.
abstract: Scanning Electron Microscope (SEM) was used to examine villous structures at different parts in the small intestines of 22-week-old chickens. Duodenum revealed plate-like villi with large number of goblet cells on the duodenal epithelium. Jejunum and ileum both revealed leaf-like villi, but the amount of goblet cells was greater in the jejunum. A putative effect of villous structures on the intestinal digestion and absorption is discussed.
