Integrated transcriptomic and metabolomic profiling deciphers breed-, age-, and rearing system-dependent regulation of muscle development and meat quality in chickens

Puntos clave

• Meat quality assessment shows significant variations influenced by breed and age, with specific biomarkers identified.
• Results indicate varying optimal conditions for muscle development based on different rearing systems over time.
• Integrated transcriptomic and metabolomic profiling methods were employed to analyze multiple factors in chickens.
• These findings highlight the importance of breed and age on meat quality, suggesting tailored approaches for enhancement.
