Influence of Selenium on the Morphology of Immune System Organs in Healthy Broilers

This study aimed to establish the effect of dietary supplementation in broiler chickens of organic and inorganic selenium on the weight and structure of the thymus, bursa of Fabricius and spleen. Three dietary regimes were studied in Flex and F15 Hubbard chickens: (i) control, (ii) diets containing...
