The present experiment was conducted in order to study the effect of temulawak extracts on the total of leucocytes in broiler chickens. The research was conducted in the Laboratory of Biology UIN Raden Fatah Palembang. The research was done by looking at the amount of the average increase before, 8 hours, and 22 days were treated with 3 replications. Twenty seven broiler chickens, 2 weeks old were used in this experiment, and were devided into 9 groups treatments, there were: (X0) negative control without the temulawak extract, (A1) 0,5 ml temulawak extract, (A2) 1 ml temulawak extract, (A3) 1,5 ml temulawak extract, (A4) 2 ml temulawak extract, (B1) 0,5 ml chemical antibiotics, (B2) 1 ml chemical antibiotics, (B3) 1,5 ml chemical antibiotics, (B4) chemical antibiotics.
