This study aimed to investigate the effect of vitamin C and aspirin on the growth performance of turkeys under normal conditions. For this purpose, 288 male turkeys, BUT6 strain, were used from 1-day-old to 12 weeks of age in nine treatments with four replications and eight birds per replication, as a 3 × 3 factorial experiment [three levels of vitamin C (V; 0, 250, and 500 mg/kg feed), and three levels of aspirin (A; 0, 75, and 150 mg/kg feed)] in a completely randomized design. Our results demonstrated that supplementing with vitamin C and aspirin had no effect on plasma total protein and albumin levels, but the data revealed significant effects on total cholesterol, triglycerides, very low-density lipoprotein (VLDL), and low-density lipoprotein (LDL) levels in the supplemental groups. Also, the interaction of vitamin C and aspirin significantly increased high-density lipoprotein (HDL) and decreased plasma malondialdehyde (MDA) and abdominal fat pad. The results of this study indicated the beneficial effects of vitamin C and aspirin supplements may be related to changes in plasma lipids and body fat under normal conditions.
