Effect of Resveratrol Supplemented to Japanese Quail (Coturnix coturnix japonica) Rations on Performance and Some Biochemical Parameters

This experiment was conducted to evaluate the changes on growth performance, carcass and some biochemical parameters of Japanese quail fed supplemental Resveratrol (Res). A total of 200 quails were distributed at equal body weights into four experimental groups, each consisting of five replicate pens having ten birds/replicate pen:1-basal diet without Res (Control), 2-basal diet + 100 mg/kg Res, 3-basal diet + 200 mg/kg Res, and 4- basal diet + 400 mg/kg Res. There were no significant effects of the supplementation of resveratrol on body weight gain and carcass traits (P>0.05). Inclusion of Res in quail rations improved feed consumption (P<0.05) and feed conversion ratio during the period from 3 to 5 weeks and the throughout (0-5 wks) of the treatment (P<0.05). Malondialdehyde decreased as compared with the control group (P<0.05), but glutathione and nitric oxide did not change by the effect of Res (P>0.05). Glucose, triglyceride, total protein was not influenced by the supplementation of Res (P>0.05). As a result, the findings of this study suggest that Res can be used safely as a growth promoter up to 400 mg/kg in quail rations.
