This study was conducted to evaluate the effects of replacing inorganic trace minerals ( ITM ) with compound organic trace minerals ( OTM ) at lower levels on plasma biochemical parameters, antioxidant capacity, carcass traits, meat quality, and tissue mineral deposition in Chinese yellow-feathered broilers. A total of 960 one-day-old male broilers were randomly allocated to six treatment groups. The birds were fed with either the basal diets (negative control, NC), or diets supplemented with 1,000 mg/kg (positive control, PC), 300 mg/kg, and 500 mg/kg ITM or OTM for 53 d, respectively. The results showed that the alkaline phosphatase ( ALP ) activity of the OTM300 group was significantly higher than that of the NC, PC, and ITM300 groups ( P < 0.05). Dietary OTM supplementation could significantly increase the serum concentrations of Fe and Cu, promote the deposition of Zn and Cu in breast muscle, and increase Zn content in the tibia of Chinese yellow-feathered broilers ( P < 0.05). Furthermore, dietary OTM300 treatment could significantly increase plasma CAT and CuZn-SOD activities, as well as the CAT activity in the liver ( P < 0.05). The liver GSH-Px activity of the OTM500 group were significantly higher than the other groups ( P < 0.05). Moreover, the supplementation of dietary OTM could significantly increase the pH 45min of breast muscle, as well as decrease drip loss 24h and drip loss 48h of Chinese yellow-feathered broilers ( P < 0.05). Furthermore, pH 45min was posit...
