In the conditions of the Republic of Belarus there were presented results of research of morphological and morphometric peculiar features of organization of micro-circulatory channel of rumen and rennet bag of newborn calves with different degrees of physiological maturity (antenatal maldevelopment), which provided a clear picture of this branch of biology about calves-hypotrophics. In course of the study there was analyzed the morphometry of vessels of micro-circulatory channel of fundic part of rennet of calves; the morphometry of vessels of micro-circulatory channel of pyloric part of rennet of calves. High carrying power of vessels of microcirculatory bloodstream of hypotrophic calves with high degree of antenatal maldevelopment was explained by transformation of genuine capillary tubes into capacitative vessels. Morphological immaturity of a system of microcirculation at calves with antenatal maldevelopment made it possible to speak about its functional inadequacy and inability for an adequate, compensatory and stable provision of blood circulation and metabolic processes in tissues in the conditions of individual development.
