Evaluation the Effects of Copper Nanoparticles Dietary Supplementation on Growth Performance, Carcass Characteristics, and Serum Antioxidant Status in Broilers.

The current study aims to assess the impact of different doses of feed supplementation of copper nanoparticles on broiler growth performance and carcass traits. The copper nanoparticles were synthesized by chemical reduction, and X-ray diffraction was used to characterize them. Iso-caloric and iso-nitrogenous starter and finisher basal diets were prepared and further supplemented with 0, 4, 8, and 12 mg/kg Cu nanoparticles for formulating T1, T2, T3 and T4 diets, respectively. A nearby hatchery provided 160-day-old broiler chicks, which were subsequently divided into 4 groups at random. There were 4 repetitions of each treatment, with 10 birds in each replication. Results revealed that average weight and FCR were improved in birds fed feed containing 12 mg nano Cu when compared to other groups. Feed intake, carcass characteristics, and dry matter and crude protein metabolizability were not influenced by different levels of Cu nanoparticles, while the metabolizability of crude fat was significantly higher (P < 0.05) in T4 compared among all treatment groups. Catalase concentration was higher (p < 0.05) in T3 and T4 compared to other treatments, while the concentration of superoxide dismutase was high in T2 and T4. The water-holding capacity of meat was significantly higher (P < 0.05) in T4. The findings of the present study concluded that dietary supplementation of Cu nanoparticles at 12 mg/kg feed can be practiced to get better broiler performance. According to the current study's findings, broiler performance can be improved by supplementing the food with 12 mg/kg of Cu nanoparticles.
