Abstract: Influence of complexed zinc supplementation on growth performance and meat quality of broiler chickens were assessed at 49 d of age. A total of 960 male broilers were assigned to four dietary treatments: negative control (C), positive control (C + IZn; 40 ppm ZnSO4), C + 40 ppm complexed Zn (C + OZn) and C + IZn + 40 ppm complexed Zn added to the positive control (C + IZn + OZn). Each treatment feed was provided in a three-stage feeding program. No differences (p>0.05) were observed in the body weight, feed conversion, carcass and component yields due to any of the dietary treatments. However, drip loss was significantly (p<0.05) increased in fillets from birds fed organic trace minerals when measured at 24 h post deboning. Overall, fillet color (L*, a* and b* measurements) did not differ significantly (p>0.05) but after 28 d of storage, fillets from birds with high levels of zinc showed increased (p<0.05) redness (a* value). Breast fillet quality and microbial profile over a 28 d storage period under refrigeration (4oC) were not different (p>0.05) due to any of the dietary treatments.
