AbstractThis study was carried out to determine the effects of peppermint (Mentha piperita L.) essential oil addition to growing Japanese quail diets on growth performance, carcass and some serum parameters. In the study, a total of 300 mixed-sex Japanese quail (Coturnix coturnix japonica) chicks at daily age were fed for 35 days with control and diets that were supplemented with peppermint oil at the levels of 0.15, 0.30, 0.45 and 0.60 %. The study was carried out in 5 treatment groups, with 6 replications, in a total of 30 subgroups. At the end of the experiment, the diet peppermint oil levels did not significantly affect the body weight, body weight gain, feed intake and feed conversion ratio. The effects of experimental diets containing different levels of peppermint oil on serum glucose, cholesterol, triglyceride, total protein, HDL, LDL, AST and ALT concentrations were statistically insignificant. There was no statistically significant difference between the treatment groups in terms of carcass weight, carcass yield, liver and heart weights, and small intestine length. According to the results of the present study, it was concluded that the addition of different levels of peppermint oil to growing quail diets did not cause any change in performance, carcass, visceral weights and serum parameters.
