The effect of using ochalyptus and mint essential oils in diet on carcass traits and digestive attached organs of broiler chickens P

The study was conducted to evaluate effects of ochalyptus and mint essential oils used in the diet on carcass traits and digestive attached organs of broiler chickens. 150 Ross 308 broiler chicks were used in a completely randomized design with 5 experimental groups (diets) and three replicates of ten chicks each (totally 10 pens). The experimental groups were negative control diet, positive control diet and diets containing blend of ochalyptus and mint essential oils. Evaluated parameters were carcass percentage and digestive attached organs. Results indicated that adding of the essential oils especially 30 ml per kg to diet had (p<0.05) significant effect on increasing carcass, thigh and breast percentage. Also, using the essential oils especially 30 ml per kg in diet decreased (p<0.05) weights of digestive attached organs in broiler chickens. These effects were more in diets containing the essential oils than diet containing antibiotic. In conclusion, usage of the essential oils especially 30 ml per kg improve carcass traits and digestive attached organs and can be a proper additive in diet for improving evaluated traits in broiler chickens.
