Selenium is an essential trace mineral that prevents the formation of pro oxidative free radicals. The role the selenium plays in the protection of hemoglobin against peroxidation is very well documented and researched. In order to perform this study, a number of 20 3-weeks-old broiler chickens of the Cobb breed were analyzed. The individuals were distributed into two even lots. The batching of the individuals was realized within the bio base of the Faculty of Veterinary Medicine in Bucharest. The duration of the experiment was of 4 weeks. Both the experimental batch and the control batch were fed a 21/1 ratio feed diet for broiler chicken, finishing period. The experimental batch’s diet was additionally supplemented with 0.5 ppm of selenium, with 0.25 ALKOSEL R397 g/kg mixed fodder. At the end of the experimental period, blood samples were taken by venipuncture of the cubital vein for hematological and biochemical laboratory analysis. The results were tabled and bio statistically interpreted. The experimental lot has shown significant increases in the values of the hematocrit (7.68%) and of the blood levels of white blood cells (14.01%), aspartate aminotransferase (8.19%), calcium (10.59%) and selenium (42.56%). They also showed a significant decrease in the values of blood protein levels (8.33%). The biochemical parameters influenced by the organic selenium supplemented feed lead to the prevention of the oxidative stress and a higher efficiency of fodder conversion rate.
