[Effect of thermal treatment of potato products on nutrient decomposition in the digestive tract of swine. 2. Nutrient content and bacterial activity in various parts of the intestine].
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.
