Morphological and biochemical blood indicators of ducklings, which are raised for the purpose of meat with the different level of selenium in feeding-stuffs

The effect of additives in feeding-stuffs with the various dose of selenium on morphological and biochemical blood indicators of ducklings, which are raised for the purpose of meat, is examined. It is established, that additives in feeding-stuffs with the different dose of selenium stimulate hemocytopoiesiswithin the physiological normal range, what the simultaneous increasing tendency of the amount of erythrocytes, leucocytes and the content of hemoglobin in the peripheral blood of young birds proves; they activate the mechanism of immune protection, that is shown with the increasing of general protein level and immunoglobin concentrations in serum. The revealed changes in the content of general glutathione in blood and its restored form confirm the positive influence of selenium on non-enzymatic link of the antioxidative protecting system of the bird organism. The inclusion of selenium into feeding-stuffs for ducklings, which are raised for the purpose of meat, more significantly reverberated through morphological and biochemical indicators of bloodata dose of 0,4 mg/kg.
