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

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
