In this research thirty specimens of duodenum of Lori-Bakhtiari sheep from abattoir were collected. The specimens were selected from male healthy sheep and aged 1 years. After collecting them and determining of three parts of duodenum (cranial, descending and ascending parts), The lengths of them were measured. For histological studies, each part of duodenum divided to two centimeter pieces and then tissue prepared. In each piece of duodenum, Brunner’s glands in tunica submucosa were measured using micrometer method. All of parameters between three parts of duodenum were analysed and compared using ANOVA test. In results, normal mean length of duodenum in Lori-Bakhtiari sheep 72.50 ±12.81 cm was determined. Normal mean length of three parts of duodenum, cranial, descending and ascending 12.05 ±2.13 cm, 26.51 ±4.69 cm and 33.74 ±5.97 cm were determined respectively. In histometrical results, thickness of Brunner’s glands in three parts of duodenum decreased from cranial to ascending part. It decreases from 574.00± 67.7µm to 313.57 ± 51.2µm respectively. There was significant difference in thickness of Brunner’s glands in three parts of duodenum(p<0. 01).
