Abstract: Lori’s breed of sheep has an economic importance for Lorestan province. In present study, anatomical and histological aspects of small intestine in this sheep were examined. Small intestine of 10 individual sheep (5 male and 5 female) were evaluated. Histological sections were prepared through H&E, PAS and Alcian blue methods. Mean length of various parts of small intestine, including duodenum, jejunum and ileum were 62/4 Cm, 14/10 m and 28/9 Cm, respectively. Histological observations showed that the shape of mucosal villi differs in various parts of small intestine. In duodenum villi are foliate in shape and toward the ileum they convert to finger-like structures. Number of goblet cells is different in three parts of small intestine but in ileum is more abundant. Deep parts of intestine are rich in mucosal goblet cells. Mucosal glands of small intestine (Brunner's gland) are not limited to duodenum but extended to first part of jejunum. Payer patches are also not confined to ileum and observed in terminal part of jejunum too.
