ABSTRACT. Elemental composition of feti (homogenate) taken from pregnant rats that were on a diet with excess or deficient intake of dietary fibers before and during pregnancy (6 weeks) was studied. The diets were based on semisynthetic casein. The deficiency of dietary fibers was modeled by excluding microcellulose from the diet; the excess of dietary fibers – by increasing the level of microcellulose consumption up to 4 g/day. It was found that the changes of the mothers' diet had the greatest impact on the contents of Ca, K, Mg, P, Co, Cu, I, Al, Sr in the bodies of the feti. Deficiency of dietary fibers in the mother's diet was accompanied by a higher content of Ca, Sr in the bodies of the feti and by a lower content of Mg, P, Co, Cu, I, Al. When excess content of dietary fibers in the mother's diet, there were found significantly lower levels of Ca, K, Co, Cu, Al, Sr in the feti that is probably explained by the absorption properties of dietary fibers. Thus the study demonstrates the effect of consumption of dietary fibers by an animal during gestation on the elemental homeostasis of the fetus.
