This study was conducted to assay the use of Saturejahortensis L. (savory) essential oil in the drinking water on broiler production and blood glucose, uric acid, creatinin and cholesterol. Four hundred and twenty day old broiler chickens (Ross 308) was used in a completely randomized design with 6 treatments and 5 replicate. Experimental treatments included: 1) control, 2) Tween (a solvent for dissolving savory essential oil in it and then in water) to the amount of 1000 ppm and 100, 200, 300, 400ppm savory essential oil were mixed in tween in drinking water for broiler chickens during the growth period, respectively for other 4 treatments.The results show that adding savory essential oil to the drinking water of broiler chickens at ages 1 to 42 days makes a significant decrease in live weight and feed intake by broiler chickens compared with the control group (P<0.05). Treatments had no effects on blood biochemical parameters of glucose, creatinine, uric acid and cholesterol. Based on the results of this investigation it seems that savory essential oil in drinking water had negative effects on broiler production.
