Effect of use different levels of encapsulated lavender essential oil supplemented diets on performance, carcass traits and characteristics in broiler Japanese quails

To determine the effect of use different levels of encapsulated lavender essential oil (Lavender EEO) supplemented diets on performance and carcass traits and characteristics in broiler Japanese quails the experiment was done with five hundred one days old quail with 5 treatments including the control group and others those consuming encapsulated lavender essential oil levels of 100 200,300 and 400 mg per kg of standard diet with 5 repetitions and 20 quail each. The feed intake (FI), body weight (BW), feed conversion ratio (FCR) and feed efficiency were (FER) calculated. At the end of the study period, two male quails were randomly selected, slaughtered and eviscerated. The carcass traits and carcass relative weights were evaluated. The proximate compositions of meat such as moisture, crude fiber and ash content percentage were determined. Data from the currents study showed that use of different levels of encapsulated lavender essential oil supplemented diets on performance such as feed intake, body weight, feed conversion ratio and feed efficiency ratio in experimental quails compared to the control but not significantly. Warm and cold carcass weights, tight and breast percentage were tended to increase insignificantly and abdominal fat percentage decreased by significantly (p≤0.05) by using of different levels of Lavender EEO supplemented diets. Additionally, data of proximate composition of thigh and breast meat showed that there were none significantly differences of moisture , crude fiber and ash contents percentage in quails were fed by different levels Lavender EEO supplemented diets compared to the control.
