title: [Development of protective functions of the pig digestive tract in ontogenesis].
abstract: It has been found that the state of protective functions of the digestive tract change during postnatal period. The biosynthesis and secretion of glycoproteins of mucus layer which is the main protective structure of digestive tract depend on the hormonal background and the nutrition conditions. The biosynthesis stages and secretion glycoproteins result in sexual maturity and in conditions of definitive nutrition. Opposite to that, the antiradical activity of adherent mucous layer decreases with age. The allocation of the studied components of adherent mucous layer in the stomach and in the intestine is determined.
