Ayak Hastalıklı Broilerde Antioksidan Metabolizma ve Kemik Dokusunda Oluşan Değişikliklerin Belirlenmesi

Leg problems are one of the most important problems in broiler breeding. In this study, a total of 20 broilers (Ross 308) 10 healthy (SG) and 10 legs diseased (AHG) were used. Superoxide dismutase (SOD) and catalase (CAT) activities and glutathione (GSH) and lipid peroxidation (LPO) amounts were measured to determine the antioxidant metabolism in some tissues. The CAT activity, GSH and LPO amounts were increased in kidney tissue of the leg diseased group (P<0.05). Again, it was determined that CAT activity and LPO amount increased (P<0.01), and SOD activity decreased in drumsticks tissue of the AHG group (P<0.05). It was observed that SOD activity, GSH and LPO amounts increased (P<0.01), CAT activity decreased (P<0.01) in AHG's breast tissue. It was determined that the CAT activity and amount of GSH increased (P<0.01), and SOD activity decreased in the heart tissue of the AHG group (P<0.01). In addition, it was observed that SOD activity (P<0.05) and GSH amount decreased (P<0.05) and LPO amount increased in liver tissue of AHG (P<0.05). As a result; it was determined that the tibial-tarsal bone tissue of the foot-diseased animals was not fully formed, antioxidant activities were significantly changed in kidney, heart, liver, drumsticks and breast meat tissues.
