a 42-day feeding experiment was performed using broilers. The chemical composition, meat color, cooking loss, tenderness, pH values, fatty acid profiles and IMF content were determined to evaluate the differences in meat quality affected by dietary P levels. Besides, to help understand how dietary P levels affect lipid metabolism in broiler chickens, the activities of enzymes including FAS, ME and AMPK in breast meat and liver were determined, trying to provide a foundation for understanding the relation of dietary P levels and meat quality.
