[Experimental substantiation of the functional relationship of mineral elements of nutrition with intestinal mucus and the mucosa membrane of the intestine].

Interaction of magnesium increased dietary level with enteral calcium metabolism through the gut wall and intestinal mucosa mechanism is described in ruminants. Magnesium excess was found in the endogenous fraction of chyme and in the intestinal mucosa and resulted in increased calcium concentration in these biological tissues. Magnesium itself did not penetrate into the internal gut environment, and calcium content in the organs and tissues was reduced. It is concluded that the interaction of minerals takes place in the gut prior to absorption, and that the intestinal mucosa is important for homeostatic balance of minerals in the digesta and in the internal body environment.
