The investigation of histological and histochemical characters of the small intestine in indigenous Gazelle was carried out during November into April 2017. The tissue samples were processed by paraffin technique and stained with the H and E, Masson's trichrom, PAS and Alcian blue stains. In duodenum the submucosa occupied by mucus and serous Brunner’s glands. The jejunum had short villi with few goblet cells. The ileum had furthermore of goblet cell with submucosal payer's patches. The goblet cells of duodenum were positive with Alcian blue (2.5pH) stain. The Brunner’s glands were weak PAS and negative with Alcian blue. In jejunum, the goblet cells of crypt were moderately and strongly with PAS and AB (pH2.5) respectively. In the ileum the goblet cells were more than the neutral in the crypts. This work concluded that the small intestine of Indigenous gazelle was similar those of small ruminant.
