Due to the important functions of arginine in poultry, it should be questioned whether currently adopted dietary Arg:Lys ratios are sufficient meet modern broiler requirement arginine. The present study aimed, therefore, evaluate effects supplementation L-arginine a commercial diet on productive performance, breast meat quality attributes, incidence and severity muscle myopathies foot pad dermatitis (FPD), plasma metabolomics profile fast-growing broilers.A total 1,170 1-day-old Ross 308 male chicks was divided into two experimental groups 9 replicates each fed either basal (CON, digestible ratio 1.05, 1.06 1.07 feeding phase, respectively) or same supplemented on-top with crystalline (ARG, 1.15, 1.16 1.17, respectively). Productive parameters were determined at end phase (12, 22, 33, 43 d). At slaughter (43 d), FPD assessed, while samples collected analyzed by proton nuclear magnetic resonance-spectroscopy. significantly reduced cumulative feed conversion compared control 12 d (1.352 vs. 1.401, P < 0.05), 22 (1.398 1.420; 0.01) 33 (1.494 1.524; also tended improve overall period trial (1.646 1.675; = 0.09). Body weight increased ARG CON group (1,884 1,829 g; 0.05). No significant effect observed occurrence. birds showed higher concentration leucine, lower acetoacetate, glutamate, adenosine proline. Arginine acetate concentrations higher, whereas acetone inosine levels (P 0.05).Taken together, these data that had positive efficiency chickens probably via modulation metabolites play key roles energy protein metabolism.
