Dry matter (DM), starch, crude protein (CP), amino acids (AA) and diaminopimelic acid (DAPA) were estimated in the contents of the digestive tract of slaughtered pigs, which were fed a basal diet with raw (rKSt) or with cooked (QuSt) potato starch. When fed rKSt, there was larger quantities of starch and DAPA in the content of the distal small intestine and also of DM, CP, AA and DAPA in the contents of caecum and proximal colon, compared to QuSt. The bacterial breakdown of the raw potato starch granules in the proximal large intestine is shown by microscopic examinations. It is suggested, that the quantity of bacterial protein excreted in the faeces did not allow to quantify the extent of the bacterial activity in the different segments of the digestive tract.
测定了屠宰猪消化道内容物中的干物质（DM）、淀粉、粗蛋白（CP）、氨基酸（AA）和二氨基庚二酸（DAPA）含量，这些猪分别喂食了含生（rKSt）或熟（QuSt）马铃薯淀粉的基础日粮。与QuSt组相比，喂食rKSt组时，远端小肠内容物中的淀粉和DAPA含量更高，盲肠和近端结肠内容物中的DM、CP、AA和DAPA含量也更高。显微镜检查显示了近端大肠中生马铃薯淀粉颗粒的细菌分解情况。有人提出，粪便中排出的细菌蛋白数量无法量化消化道不同部位的细菌活性程度。
