Abstract

This study aimed to assess the impacts of dill oil on growth performance, oxidative status, and economic efficiency of Japanese quails. A total of 300 one-week-old unsexed Japanese quails were randomly distributed into 4 equal groups (75 birds into 5 replicates/group). The 1st group (control) was fed a diet without any dill oil, while dill oil was added at levels of 250, 500, and 750 m per ton of feed, respectively at the 2nd, 3ed and 4th groups. At the age of 3 and 5 wks, the best values of productive performance represented in body weight, weight gain, feed consumption and feed conversion ratio were achieved in groups fed diet supplemented with 500 and 750 m dill oil/ton of diet. A significant (P≤0.01) improvement was achieved in antioxidant status; especially in the levels of both SOD and GSH enzymes while, decreasing the amount of MDA in blood plasma. Japanese quail fed diet supplemented with 750 g/ton had the highest relative economic efficiency followed by those fed diet supplemented with 500 g/ton by 23.51and 21.43% respectively, compared to the control group. It could be recommended that, supplemented diet with dill oil up to 750g/ton improved the productive performance traits, antioxidative capacty and economic efficiency of Japanese quails.
