The experiment was conducted to investigate the effect of in ovo injection and dietary feeding of flavonoid (Naringin & Hesperidin) on performance, carcass quality, meat antioxidant stability and hindgut microflora by total 600 fertile eggs were used for amnion injection (17.5th day of embryonic) and hatched chicked divided randomly in four replications with 10 birds for growing period until 42d. Treatments by completely randomize design were 1, 2 and 3) 50, 100, 175 mg/kg flavonoids in diet, respectively, 4 and 5) 15, 30 mg/egg injection of flavonoid respectively and 6) injection of 15 mg/ egg and feeding 50 mg/kg flavonoid and 7) injection of 30 mg/ egg and feeding175 mg/kg and 8) control group. Treatments did not have a significant effect on performance traits compare to control group. Reduction of Malondialdehyde substances in tight and breast meat were observed in treatments (except 4) at 28 and 42 days than in the control group significantly (P<0.05). The results showed an increase in population of aerobic and Lactobacillus and reduction in Coliforms of treatments than the control (P<0.05) group. Therefore, adding 175 mg with or without 30 mg injection (high levels) of flavonoid to diet improved meat quality and dietary with 50 mg with or without 15 mg of flavanoid injection caused improvement in microbial population in hindgut. In overall dietary with or without injection of flavanones have positive effects on health and meat quality of broilers.
