It has been established that during artificial feeding with milk substitute containing different protein components (casecite, bovine serum albumin, fibrinogen), the proximal-distal gradient of cavitary digestion of proteins is observed, with this gradient being more demonstrable as compared with natural feeding of postnatal animals. It has been shown that during experimental natural feeding, the proximal-distant gradient is observed in the distribution of acid proteinases in the small bowel, whereas during artificial feeding one can see a uniform distribution of acid proteinases in the proximal and distal parts of the small bowel. The activity of acid proteinases in the gastric mucosa of 18-day-old animals kept on natural feeding does not differ from the activity of these proteinases under artificial feeding with a substitute containing casecite as protein component. Artificial feeding with a substitute containing bovine serum albumin and fibrinogen as protein component entails a decrease in the activity of acid proteinases in the gastric mucosa. |
