Abstract. We studied histo-morphological changes in the bodies of the mother and fetus cattle herds after sanitation owned economy of the Sverdlovsk region, dysfunctional on white muscle disease. During the year, all cows of the herd two months before the expected date of calving were given intramuscularly 10 ml E-selenium, then ten days later – 10 ml Sedimin-Se and after another ten days – again 10 ml E-selenium. Also, E-selenium was administered to cows after calving and to youngsters in therapeutic doses. To control the results, we have taken material from the cow and its fetus at the forced slaughter of the ninth month of pregnancy. Tissue slices and organs were used for research. The material was delivered to the laboratory in 10 % formalin solution. Histological studies were performed according to the conventional scheme, through the fill material in paraffin, sectioning followed by hematoxylin and eosin staining. As a result of histological examination we obtained the following data. In the muscle tissue of the heart of the mother can be seen a slight granular degeneration of myocytes. In skeletal muscle against the background of the main muscle tissue areas are visible, which are intensely colored with eosin and fuzzy striated striations that can be attributed to the newly formed muscle fibers, which occupy large areas. Histological study revealed the fetal heart muscle formation continued. Muscles are uniformly colored, blood vessel formation in the state.
