Resumo: 	ABSTRACT We hypothesized that the supplementation of vitamin C (Vit. C) and coenzyme Q10 (CoQ10) alone or in combination could reduce the negative effects of cold stress in broilers. Four hundred male chicks were exposed for 24 h to cold stress (15 ºC) starting from 15d of age, while a positive control group (PC, 100 birds) was kept under normal temperature condition. The experimental groups under cold stress (four treatments in 5 replicates of 20 birds) were: negative control (NC, basal diet), Vit. C (basal diet + 300 mg/kg Vit. C), CoQ10 (basal diet + 40 mg/kg CoQ10) and Vit. C plus CoQ10 (basal diet + Vit. C+ CoQ10at above mentioned doses). Vit. C or CoQ10 supplementation were restored (p&lt;0.01) performance and lowered (p&lt;0.01) ascites mortality. Blood hematocrit and hemoglobin concentration were decreased (p&lt;0.01) to the level comparable to PC by Vit. C supplementation. Lower plasma concentrations of thyroxin (T4) and higher triiodothyronine (T3) were observed in NC birds (p&lt;0.01) and were not affected by Vit. C or CoQ10. In conclusion, supplementation of Vit. C or CoQ10 in diet of broilers under cold stress conditions resulted improved performance parameters (body weight and feed conversion ratio) and ascites related traits (low red blood cell count, hematocrit, T3, and heart weights and high T4). No additional benefit was observed by combination of Vit. C and CoQ10.
