Green to investigate the effect of adding different levels of the Nutrient powder to the ration in some physiological characteristics of the blood of broiler chickens Ross 308. Use the 180b roiler chicks Ross 308 day-old were randomly assigned to four treatments (by 3 replicates per treatment 15 chicks per replicate), and treatments were as follows: first treatment (control) without adding Nutrient powder to the ration, add Nutrient powder by 5 g / kg feed (second treatment), add Nutrient powder by 7.5 g / kg feed (Third treatment) and add Nutrient powder by 10 g / kg feed (four treatment). Blood traits included in this study were : Red blood cells counts, hematocrit, hemoglobin concentration, Mean Corpuscular Volume (MCV), Mean Corpuscular Hemoglobin (MCH) and Mean Corpuscular Hemoglobin Concentration (MCHC). The results indicated no significant differences between the experience of all treatments in the qualities that have been studied except recipe Mean Corpuscular Volume (MCV) and Mean Corpuscular Hemoglobin (MCH), where outperformed Third-treatment when the fifth week was significantly (P <0.05) compared to other treatments.
