On histological study is found that the small intestine of the Bronze Turkey has four layers: tunica mucosa, tunica submucosa, tunica muscularis and tunica serosa.On the first day after hatching, the epithelial cells are oval in shape, which later acquire a columnar shape with pronounced morphological polarity.The ratio of the height of the intestinal villi to the depth of the crypts increases in the first 28 days for all segments of the small intestine (12)The intensity of growth of intestinal crypts in the first 90 days has similar trends in the duodenum, and the fastest growth rates have been found for crypts in the ileum.Tunica mucosa has lamina epithelialis, lamina propria and lamina muscularis mucosae.Lamina epithelialis is composed of a single layer of columnar epithelium.
