    Volatile oils like rosemary, thyme and fennel oils have positive effects on poultry health and yields. The aim of this study were to investigate the effects of volatile oils on some serum biochemical parameters, growth hormone activities and growth performance in broiler chickens. A total of 180 broilers were randomly divided into 6 groups and 3 replicates of 10 animals according to supplementation of thyme oil, rosemary oil, fennel oil, oil mixture 100 ppm dosage and oil mixture 200 ppm dosage. Serum growth hormone activity and glucose concentration were not affected by dietary addition of volatile oils according to groups. However, addition of rosemary oil, thyme oil and fennel oil showed an effect on decreased serum cholesterol and partially lipid concentrations in the present study. In conclusion, supplementation of volatile oils had impressive effects on serum total cholesterol and total lipids levels in broiler diets. Whereas, growth performance results were not affected by dietary addition of volatile oils in our study.
