In the study, four groups were established: Control (basal diet + 24°Ctemperature), Stress (basal diet + 34°C temperature), Vit C (basaldiet + 250 mg L-ascorbic acid/kg ration + 34°C temperature and ALA (basal diet+ 250 mg α-lipoic acid/kg ration + 34°C temperature). Catalase (CAT) andsuperoxide dismutase (SOD) activities with lipid peroxidation (LPO) andglutathione (GSH) levels were determined in the liver and drumstick meattissues of the animals slaughtered at the end of the study. It was determinedthat heat stress negatively affected CAT and SOD activities with LPO and GSHlevels in liver and drumstick meat tissues. Vitamin C significantly restoredhepatic CAT and SOD activities with LPO levels, and drumstick CAT and SODactivities with LPO levels. α-lipoic acid significantly restored hepatic SODactivity with LPO and GSH levels, and drumstick LPO and GSH levels. Inconclusion, while heat stress negatively affects antioxidant metabolism inliver and drumstick meat tissues, it has been determined that the antioxidant effectsof vitamin C and α-lipoic acid supplementation may vary depending on thetissues.
