Influence of organic selenium food supplements on age-related changes on antioxidant system in thigh muscle of broiler chickens
The influence of organic selenium food supplements on activities of antioxidant enzymes, reduced glutathione (GSH) concentrations and lipid peroxidation in thigh muscle (m. biceps femoralis) of Ross heavy line chickens were investigated. At the age of 2, 4 and 6 weeks ten chickens from standard diet fed (control) group and pair-fed with the same diet supplemented with 0, 3 ppm organic selenium (experimental) group were sacrificed. Thigh muscle homogenates were analysed for glutathione peroxidase (GPX), copper zinc superoxide dismutase (CuZnSOD), manganese superoxide dismutase (MnSOD) activities and glutathione (GSH) and lipid peroxide (TBARS) concentrations. GPX activity in experimental chickens significantly increased with age whereas MnSOD activity and concentrations of GSH and TBARS decreased. During fattening period control six weeks old group showed the highest GPX and the lowest CuZnSOD, MnSOD activity and GSH concentration. Organic selenium food supplements resulted in higher GPX and MnSOD activities with simultaneous decrease of CuZnSOD activity, GSH concentration and lipid peroxidation intensity.
