The present study deals with pathoanatomic and pathohistological changes of spontaneous vitamin E and selenium deficiency in growing piglets.
The studies took place in 1990–1997 on the territory of Plovdiv area, the material involved 84 carcasses of dead pigs and 27 carcasses of pigs slaughtered by necessity.
