Nowadays, broilers reared in intensive farming become more susceptible to oxidative stress, which impairs their performance and the quality of products. Arginine (G) is a crucial amino acid for chickens feeding on arginine beyond recommended levels has been shown positively impact growth broiler immunity. Olive leaves phenolic extract (OLE) natural source powerful antioxidants. The current study aimed investigate combined efficacy these functional feed additives (G + OLE) enhancing broilers' performance, immunity, muscle development, as well potentiating meat antioxidant capacity during freezing. Broilers (n = 250) were randomly assigned into control (without supplementations) four groups fed diets plus 1.5 g/kg alone or with three different OLE; 0.25%, 0.5% 1% OLEǀ, G OLEǀǀǀ OLEǀǀǀ, respectively). During whole rearing periods, OLE inclusion boosted body weight gain, conversion ratio dose-dependent manner. postmortem pH values at 0.5, 24 h, drip loss, cooking loss % considerably minimized OLE-supplied groups, especially high levels. Even after 4 weeks frozen storage, OLEǀǀ exhibited most prominent increase breast scavenging ability free radicals (2,2-diphenyl-1-picrylhydrazyl, 2,2'-azino-bis (3-ethylbenzothiazoline-6-sulfonic acid, ferric reducing power) an inverse minimization lipid peroxidation attributes (malondialdehyde). Total flavonoid, contents, total capacity, enzymes' activities significantly improved by increasing concentrations dietary OLE. Concordantly, upregulation genes encoding immunity (immunoglobulins A, M), enzymes (catalase, superoxide dismutase, glutathione peroxidase, peroxiredoxin-1, heme oxygenase-1, NAD(P)H dehydrogenase quinone 1, xanthine oxidoreductase, oxygenase 1), development (myogenic determination factor, myogenin mammalian target rapamycin), downregulation myostatin, remarkably recognized groups. outcomes supported usage innovative supplement industry improve broilers` production, storage.
