المستخلص: اجريت الدراسة الحالية على (216) فرخ دجاج نوع Rose 308مصاب بطفيلي Emiria tenella خلال المدة من شهر نيسان 2013 الى شهر تشرين الاول 2013, وقد تم في الدراسة الحالية تحديد بعـــــــــض المؤشــــــــــــــرات الدمــــوية (الخلايا المتغايرة /الخلايا اللمفاوية HL | This study was conducted to (216) broilers chickens (Rose 308 Trade) infected parasite with Eimeria tenella performed form April 2013 till October 2013, has been in the current study to identify some indicators of blood(Heterophils/ Lymphocytes, White Blood Cell, Red Blood Cell, Packed Cell Volume, Hemoglobin) and biochemistry (Glucose, cholesterol and total protein) and productive performance (Weight increase, Food conservation, Cansumbtion and Body weight befor slugtery) , We note at the parasite has infected chicks were used three extracts of Aloe vera (alcoholic and hot water and cold water), dosage chicks were to demonstrate the effect of different concentrations of these extracts on the productivity and physiological traits mentioned above. Then the experiment was designed, which include the following : 1 - The first group (control group) included 36 chicks and was given food with no anti - coccidial. 2 - The second group include 36 chicks in duplicate was infected but did not treated.3 - The third group inclouded 36 chicks in duplicate was given extract of Aloe vera Alcoholic ethyl in adose of (0.5 - 1.5 - 2)gm per mm body weight.4 - The fourth group inclouded 36 chicks in duplicate was given extract of Aloe vera Cold water in adose of (0.5 - 1.5 - 2)gm per mm body weight.5 - The fifth group inclouded 36 chicks in duplicate was given extract of Aloe vera Hot water in adose of (0.5 - 1.5 - 2)gm per mm body weight.6 - The sixth group include 36 chicks in duplicate was given Vetacox(trade Mark)that had both Sulphadimidin 80 gm and Diverdin8 gm.Results showed the following : - 1 - The alcoholic extract of Aloe vera at concentration (0.5, 1.5, 2) g/ml after an infection in the fifth week revealed alittle effect on the H/L when compared with eighth week of infection. also this extract lead to increase, the rate of (PCV), (Hb) , and (RBC) while lead to decrease the rate of (WBC) after eighth week of infection at concentration (2)g/ml. Also this extract lead to increase the rate of cholesterol, total protein and the rate of weight increased in the eighth week, while the amount of feed intake and feed conversion showed alittle effect, as well as the body weight befors slaughter has astrong effect at concentration(2)g/ml in the eighth week of infection. 2 - The cold and hot aquatic extract of Aloe vera at concentration(2)g/ml lead to decrease the ratio of H/L and increase the rate of (PCV), (Hb) and (RBC) after the infection in the eighth week, also lead to decreas the rate of (WBC) and increase the rate of cholesterol, total protein, the rate of weight increased, the amount of feed intake and the body weight before slaughter at concentration (2)g/ml in the eighth week of infection. Also recorded abetter efficiency of feed conrersion at concentration (2)g/ml in the eighth week of infection.
