Abstract:The pancreas is an important digestive organ. Previous anatomical and histological studies on porcine pancreas mainly focused on the distribution of blood vessels and ducts. In this research, 24 control animals in another experiment were used to observe and measure the histo-morphological data of the pancreas of Bama minipigs. The result showed that the pancreas morphology of Bama minipigs is quite different. As a whole, the gross structure can be divided into 3 lobes, namely, spleen lobe, duodenal lobe and connecting lobe. According to the size, it can be divided into 3 types: the standard type, the thin type and the thick type ( among the 24 pigs, 3 types account for 16 / 24, 6 / 24 and 2 / 24, respectively) . The relative weight of pancreas accounts for 0. 09% to 0. 15% of body weight. The islets of Bama minipigs are generally small, and most of them are ultra-small type which compose of endocrine cell clusters. The relative weight of islets account for 1. 52% to 4. 98% of the pancreas and β cells account for 0. 012% to 0. 024% of body mass.
