Livestock and poultry industries require eco-friendly antibacterial agents and growth promoters due to the ban on antibiotics in the European Union and China. High-dose copper is considered a bactericide and has the advantage of growth promotion in animals, but it also disturbs the absorption of other metal elements and causes heavy metal residues. In this experiment, a nano-composite of copper and carbon (NCCC) was chosen as an alternative copper donor, hoping to not only inherit the growth-promoting merit but also diminish the disadvantage of excess copper. Hence, the effects of NCCC on growth performance, immune function, and antioxidant capacity of yellow-feathered broilers were explored, and we discovered that there were no copper residues in liver, serum, and feces after 50 or 100 mg/kg NCCC treatment. Meanwhile, obvious increases in levels of serum IL-10 and IL-4 were observed with NCCC dosage increment, despite no notable changes in the growth performance, slaughter performance, and liver antioxidant ability of chickens. As a result, NCCC has been found to optimize serum cytokine pattern but not promote the growth of broilers.
