This paper was conducted to monitor the effect of mixed essential oils (AROMIX@) as phytogenic extract herbs administration in drinking water on growth performance, hematological, biochemical, immunological statuses and carcass traits of broiler chickens. A total number of 240 unsexed broiler chicks (Cobb-500) strain, were randomly divided to four equal groups, 60 chicks each at seven days of age. The first group drank tap water (control), the second, third and fourth group were drank the same water, adding 1 ml AROMIX@per 5, 10 and 15 liter tap water, respectively for 5 week of age. It was cleared from the results that there was a significant improve in feed conversion ratio, red and white blood cell counts, total protein, albumin, globulin, calcium, inorganic phosphorus and a relative reduction in the liver enzymes but in the normal range. However, it was observed that mix essential oils have no significant impact on carcass organs. High levels of the vital parameters, low levels of hepatic enzymes showed that birds health was good and relative improvement in immune system. The relative improvement of the absorption of minerals such as calcium and inorganic phosphorus to the positive role of essential oils. Administration in drank water was occasion, a regular activity of hepatic enzymes which can evidence safety and hepato-protective nature of these oils. Therefore, it is cleared from the results that the addition of these extract herbs in drinking water enhances the health meat, performance and physiological status of broiler chicks, which helps to obtain healthy meat and suitable for human consumption.
