Abstract Study was carried out to assess supplemental effects of dietary reduced ubiquinol (rCoQ10) on lipid profile and serum antioxidant activity in broiler chicks fed diets with three energy levels. 270 broiler chicks divided into nine groups (3 energy levels x 3 levels of rCoQ10) with three replicates. Birds were fed with basal energy (BE), low energy (BE-100 (kcal)) and high energy (BE+100 (kcal.kg−1) feed) and rCoQ10 at 0, 20 and 40ppm. Broiler chicks were distributed in completely randomized design and reared for 42d and at end of study, serum and muscle samples were collected for antioxidant activities, lipid contents. The activity of superoxide dismutase, glutathione peroxidase, reduced glutathione, vitamin E were increased and serum malonaldehyde, total, LDL-cholesterol as well as muscle cholesterol were reduced by intake of rCoQ10. The consumption of rCoQ10 improved muscle oxidative stability than the control. Ubiquinol at 20ppm favourably altered lipid profile with reduced lipid peroxidation and improved serum antioxidants activities.
