A total of 360 one-day-old male broiler chicks were randomly and equally allocated into six experimental groups (six replicates each) as follows: G1 group was the un-supplemented (control) group, G2, G3, G4, G5, and G6 groups received diets with Naringin (NR) at 0.5, 0.75, 1, 1.25 and 1.5g/kg diet. The experiment lasted until the marketing age (35 days old). The results revealed that NR inclusion, particularly at 1.25 and 1.5 g/kg, improved body weight and body weight gain at the 4th and 5th weeks of age. Feed intake increased in all treated groups in the 3rd and in G2, G5, and G6 in the 5th weeks of age but was unaffected in the remaining experimental periods. Dietary NR supplementation, particularly at higher levels, improved the feed conversion ratio in all experimental periods except the first and second weeks. All studied carcass and hematological indices were not affected by NR inclusion. Serum concentrations of aspartate transferase and alkaline phosphatase were reduced in G5 and G6, while alanine transferase, uric acid, and creatinine levels were not affected by NR supplementation. In conclusion, dietary NR incorporation, particularly at 1.25 and 1.5 g/kg diet, improved broilers' growth performance without affecting carcass traits and hepatic and renal function.
