The Effect of Giving Jaloh Extract Combined Turmeric Extract Towards Differential Leukocyte Broilers Infected with Eimeria tenella ABSTRACT The aim of this research was to find the effect of giving jaloh extract combined with turmeric extract towards differential leukocyte broilers infected with Eimeria tenella. This research used samples of 20 Cobb broilers strain of chickens aged 14 days. Design used was Completely Randomized Design (RAL) with five treatments and each treatment consists of four repetitions. First treatment (KN) as negative control which is only given mineral water; second treatment (KP) as positive control which is given 5 mg/L Vita Chick in drinking water; Third treatment (P1) given 1000 mg/L Jaloh extract; Fourth treatment (P2) given 250mg/L turmeric extract; and fifth treatment (P3) given 1000mg/L jaloh extract combined with 250mg/L turmeric extract. Extract and Vita Chick treatment dissolved in drinking water. All treatments have been conducted for 10 days starting at 08.00 a.m. until around 06.00 p.m. Next inoculated Eimeria tenella sporulatif for 1 x 10 ookista/ml when the chicken 25 days old. Then perform blood sampling when the chicken 30 days old. Blood sampling performed in the brachial vein. Furthermore, calculation the average percentage of eosinophils, basophils, heterophile, monocytes and lymphocytes. Data were analyzed using anova completely randomized design with the help of SPSS for Windows 18.0 program. Result from further test Duncan showed that significant effect towards the average percentage of lymphocytes with highest average from giving jaloh extract by 65% and lowest average at negative control by 35%. This research can be concluded that giving jaloh extract combined with turmeric extract not affected (P>0.05) the average percentage of eosinophils, basophils, heterophile, and monocytes from chicken blood that infected with Eimeria tenella. But, giving jaloh extract combined with turmeric extract give significant effect (P
