[Proteolysis of blood plasma proteins in the stomach in early ontogeny].

Proteolysis of milk substitutes containing fibrinogen, casecid and bovine serum albumin as protein components was studied. Artificial feeding of newborn rats has shown high casecid and fibrinogen utilization. Casecid and fibrinogen contained in milk substitutes delayed protein evacuation from the stomach, while bovine serum albumin intensified protein evacuation. Adaptive changes in enzyme-forming gastric function depend on the protein quality.
