Abstract:

This study was conducted to investigate the effect of dietary supplementation with pyrroloquinoline quinone (PQQ) in the form of PQQ disodium (PQQ·Na2) on the growth performance, carcass traits, meat quality and antioxidative ability of broilers.  A total of 720 one-d-old Arbor Acres 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·Na2-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·Na2 kg–1 for 42 d.  Compared with the control chicks, the chicks fed the diets supplemented with PQQ·Na2 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·Na2 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·Na2 can improve antioxidant ability and meat quality  of broilers, and in general, it is implied that the optimal supplemental PQQ·Na2 level is 0.1 mg kg–1 of diet for broilers from 1 to 42 d of age.
