Aim: This study was carried out to determine the effects of the usage of sage (Salvia triloba L.) and laurel (Laurus nobilis L.) oils in diets on some performance and carcass parameters of quails.

Materials and Methods: A total of 800 three-day-old Japanese quails (Coturnix coturnix japonica), including both males and females, were divided into 10 groups containing 80 quails. Each group was divided into four replicates containing 20 birds each. These groups were as follow: No oil group (Control), 100 mg/kg sage oil group, 200 mg/kg sage oil group, and 400 mg/kg sage oil group, 100 mg/kg laurel oil group, 200 mg/kg laurel oil group, 400 mg/kg laurel oil group, 100 mg/kg sage oil + 100 mg/ kg laurel oil group, 200 mg/kg sage oil + 200 mg/kg laurel oil group, and 400 mg/kg sage oil + 400 mg/kg laurel oil group. The experimental period was lasted for 35 days.

Results: It was determined that in all experimental groups supplemented with sage, laurel and sage + laurel oils, no differences (P>0.05) were observed in terms of body weights, body weight gain, feed intake and feed conversion ratio. Morover, hot and cold carcass weights and relative weight of liver, heart, spleen, gizzard and proventriculus plus gizzard were not affected by supplementation with sage, laurel and sage + laurel oils (P>0.05).

Conclusion: It may be concluded that sage, laurel and sage + laurel oils supplementation in the quails' diets had no effect on performance and carcass parameters.
