title: [The physiological mechanisms of the delay in the functional maturation of the small intestine in rat pups prematurely switched from milk to definitive nutrition].
abstract: Weaving of 15-day rats delays the natural suppression of the small intestine lactase, induces sucrase activity and decreases the thyroxine level in the blood serum. Administration of thyroxine normalizes the level of this hormone in the blood serum as well the beginning of suppression of the lactase activity.
