[Effects of surgical removal of the Brunner's region of the duodenum on nutrient digestibility in rats].

In 1.5 months after surgical ablation of duodenum of Brunner's region the digestibility of proteins, carbohydrates, lipids and minerals was investigated in Wistar male rats. Estimation was based on the measurement of consumed and excreted nutrients. The rats with a bypass gastroduodenal anastomosis and sham-operated animals were used as a control. It was ascertained that Brunner's region of ablated rats showed a reduced proteins digestibility. Possible reasons for change established are being discussed. Participation of duodenal glands in digestion is suggested.
