Abstract

Under the influence of various hormones, the development of the digestive system can clearly change. Under the action of the hormone thyroxine, the activity of lactase is prematurely suppressed. The sucrase activity is induced prematurely. The repressive and inductive effects of the enzyme depend on the age of the animal, which was observed only in the middle and second half of the lactation period. Age-related changes in intestinal enzymes under the influence of hormones occur in the presence of complex mechanisms.
