One day old, 240 chickens (Ross-308) were used as animal material. The study was divided into 1 control and 3 experimental groups and each group had 4 subgroups with 15 chickens.
The mean body weights (BW) and body weight gain (BWG) of the control and experimental groups were examined during the study. The mean body weights (BW) and body weight gains (BWG) for control and experimental groups were 2323.53 g, 2399.91 g, 2418.27 g and 2462.36 g, respectively. The BW and BWG were higher and statistically significant (P <0.05) in the first, second and third experimental groups compared to the control group. The average feed consumption in the control and experiment groups were calculated as 4111,93 gr, 4376,04 gr, 4214,29 gr and 4317,51, respectively, while there was no difference between the groups, while the feed utilization rates in the control and experimental groups were 1,81, 1,82, 1.73 and 1.75, respectively. While there was no statistical difference in feed utilization rates, it was calculated numerically in the lowest (better) groups 2 and 3. At the end of the study, there was no difference between control and experiment groups in hot carcass, carcass yield, heart, liver, stomach and spleen weights.
This study showed that the mixture of essential oils and organic acids at different levels in broiler rations significantly increased the body weight and body weight gain while negatively affecting the performance of the animals and positively affected the feed utilization rate.
