[Effect of diet on the formation of chyme and the rate of absorption of nutrients during active digestion].

In dogs with multiple fistulae the rate of absorption of nutrients from enteral lumen using different nutrient mixtures, revealed that the composition of chyme at the entrance into small intestine is homeostased within a certain range of values differing from the diet. A considerable increase of some nutrient in the diet leads to an increase of its content in the chyme and to considerable acceleration of absorption from the gastroduodenal part.
