This experiment was designed to study the effects of a hydroalcoholic fruit extract from Withania coagulans (WC) and α -tocopherol acetate ( α -Toc) in diets containing oxidised oil on growth performance, immune response and antioxidant indices of broiler chickens. The experiment was arranged 2 × 3 × 2 factorial comprising the oxidised oil (0% and 2% diet), WC (0, 100 and 200 mg/kg diet) and α -Toc (0 and 200 mg/kg diet). A total of 600 1-day-old male broiler chickens of the Ross strain were randomly allocated to 12 treatments with 5 replicates of 10 birds each. On day 42, one bird from each replicate was sacrified to measure the lymphoid organ weights, intestinal morphometric characteristics, and malondialdehyde content in the thigh meat. Dietary inclusion of oxidised oil significantly reduced the body weight gain in birds receiving no dietary WC ( p < 0.05). In contrast, dietary supplementation of WC at 100 mg/kg diet in birds fed with the diets lacking in WC and oxidised oil resulted in significant increase in body weight gain ( p < 0.05). Dietary supplementation of WC significantly increased the total anti-sheep red blood cell titre ( p < 0.01). The birds fed with the dietary oxidised oil revealed significantly higher values of malondialdehyde and lower glutathione peroxidase and superoxide dismutase activities ( p < 0.05). Feeding diets containing WC resulted in a significant decrease in malondialdehyde content in thigh meat while conversely, increased the glutathione peroxidase and superoxide dismutase activities ( p < 0.05). The findings indicated that the dietary inclusion of WC could be recommended as a potent alternative to synthetic compounds in order to improve broilers performance, immunity and meat quality under oxidative stress conditions. |
