¹Values are means of five replicates per treatment with 12 broilers each.

²ADG, average daily gain; ADFI, average daily feed intake; G:F, gain:feed.

³Group CON: basal diet; Group N50: basal diet added with 50 mg/kg nano-composite of copper and carbon (NCCC); Group N100: basal diet added with 100 mg/kg NCCC; Group N200: basal diet added with 200 mg/kg NCCC.
