Impact of dietary arginine (G) and G/olive leaf extract (OLE) on the transcription of genes related to muscle development in the breast meat samples of broilers at 22-and-35 days of age (A-D). A: MyoD (myogenic determination factor); B: MyoG (myogenin); C: MSTN (myostatin), and D: mTOR (the mammalian target of rapamycin). The data are displayed as means ± standard error of the mean (SEM). a, b,c various superscript letters imply statistical significance (p < 0.05). Control: chicks fed basal diets without any supplementations, G: chicks fed control diets fortified with 1.5 g/kg arginine (G), G + OLEǀ: chicks fed control diets fortified with 1.5 g/kg G plus 0.25% olive leaf extract (OLE), G + OLEǀǀ: chicks fed control diets fortified with 1.5 g/kg G plus 0.5% OLE, and G + OLEǀǀǀ: chicks fed control diets fortified with 1.5 g/kg G plus 1% OLE
