摘要： This study was conducted to investigate the effect of dietary supplementation with pyrroloquinoline quinone (PQQ) in the form of PQQ disodium (PQQ center dot Na-2) on the growth performance, carcass traits, meat quality and antioxidative ability of broilers. A total of 720 one-d-old ArborAcres male broilers were randomly allocated to 1 of 6 treatments with 8 replicates of 15 birds per replicate in a completely randomized design. Birds were fed a PQQ center dot Na-2-unsupplemented corn-soybean meal basal diet (control) or the basal diet supplemented with 0.1, 0.2, 0.3, 0.4 or 0.5 mg PQQ center dot Na-2 kg(-1) for 42 d. Compared with the control chicks, the chicks fed the diets supplemented with PQQ center dot Na-2 had lower (P<0.05) feed:gain (F/G) during the grower phase and drip losses of breast muscles on day 42. As supplemental PQQ center dot Na-2 level increased, plasma total antioxidant capacity (T-AOC) on d 42, liver T-AOC on d 21 and heart T-AOC on d 21 and 42 increased linearly (P<0.05), but malondialdehyde concentrations in plasma, liver and heart on d 21 or 42 decreased linearly (P<0.001) or quadratically (P<0.005). The results from the present study indicate that dietary supplemental PQQ center dot Na-2 can improve antioxidant ability and meat quality of broilers, and in general, it is implied that the optimal supplemental PQQ center dot Na-2 level is 0.1 mg kg(-1) of diet for broilers from 1 to 42 d of age.
