Abstract
The processes of protein digestion and amino acid absorption in the digestive tract of the pig have been studied to understand what factors influence the amino acid supply to the organism. This chapter discusses a study to analyze the course of protein digestion and amino acid absorption in pigs. In a study, the daily secretion of nitrogen in the proximal, middle, and distal regions of the small intestine was estimated on pigs of 50 to 75 kg live weight. The secretions in the proximal and middle regions of the intestine were twice as high as those in the distal region. When the Krebs–Ringer solution used for washing the intestinal loops was made hypertonic by adding 5% glucose, the nitrogen secretion increased in all the regions of the intestine. After a protein-free diet was fed to the pigs for 3 days, the secretion of nitrogen decreased substantially. From these data, it was calculated that the daily secretion of crude protein in the small intestine may be 90 g on average.
