Effects of genotype and severity of muscle myopathies on malondialdehyde and total antioxidant capacity in broiler chickens

Abstract

Objective: This study was conducted to investigate the effects of different severities of wooden breast and white striping myopathies on oxidative stress markers in broiler chickens of Cobb and Ross genotypes. Material and Methods: In the study, a total of 120 pectoralis major muscle samples collected from broiler chickens were classified according to pathological severity (normal, moderate, and severe). Sample selection was performed using visual inspection and palpation methods. Results: For wooden breast myopathy, the Cobb genotype exhibited significantly higher malondialdehyde levels (0.91 vs. 0.79 mg/kg; p<0.0001) and lower total antioxidant capacity values (8.96 vs. 9.36 µmol TE/g; p<0.0001) compared to the Ross genotype. In the case of white striping myopathy, malondialdehyde levels in the severe group (0.89 mg/kg) were significantly higher than those in both the moderate (0.84 mg/kg) and normal (0.78 mg/kg) groups (p<0.0001). Conclusion: These findings reveal that different genotypes exhibit distinct oxidative stress responses to varying degrees of myopathy and that genotype selection plays a determining role in oxidative stability.
