Selenium (Se) intake in human is rather low in many countries (Combs 2001). Different strategies to increase human selenium intake were summarized recently by Lyons et al (2003). Selenium fertilization of crops and grass based on the Finnish experiment of the early 80 trebled Se intakes and nearly doubled plasma Se concentration within 3 years of programme’s initiation. Meat from Se supplemented animals contains Se at a high level so that such a meat contributes to a large extent of Se supply for man. The aim of the present work was to assess the effect of selenium enriched winter barley in fattening bulls with large muscle development.
