This study was carried out to determine the effect of the herb and Urtica dioica of the vitality of the Eimeria tenella, it conducted on 150 Ross broiler chicks, divided randomly on the seventh days into six groups. The last two groups (five and six) were considered as a positive and negative control groups, the first five groups were experimentally infected by 1000 oocysts/bird of Eimeria tenella at 17 days old directly in to the crop. The first four groups were given Artemisia herba alba and Urtica dioica According to concentrations for each group. Results were indicated a higher significant differences ( P<0.05 ) in the means of PCV for the groups that treated water herbs extracts of Artemisia herba alba and Urtica dioica (38.5±1.3 ,39.5±1.6%) respectively compared to positive and negative control groups (32.0 ±1.0, 33.0±1.13%) ; also , increase in the means of Hb concentration in the groups which treated with the Urtica dioica in food (14.2 ± 1.1 gm/100ml) and water extract (15.4 ± 1.2 gm /100 ml ) respectively compared to the control groups. A higher significant differences (P<0.05) were recorded in means of WBCs of the water extract of both herbs Artemisia herba alba and Urtica dioica (30.8 ± 0.3 ,31.0 ± 0.3 x103cell/ml) respectively compared to control group. While the differential count of WBCs were showed a significant decrease (P<0.05) in the heterophils of both herbs of water extracts of Artemisia herba alba and Urtica dioica (20.4±1.5% , 19.0±1.7%) respectively, especially at 5th week compared to control positive and negative groups. In conclusion used herb Urtica dioica especially aqueous extract enhance immune efficiency as well as the aqueous extract of the Artemisia herba-alba herb. And use the standard doses of 1% or less from Artemisia and Urtica dioica fodder and water are safety doses without mortality or side effects in broiler. Further studies are needed to (re) evaluate effect of Urtica dioica, Artemisia on other parasites.
