Jamu consists of a mixture of temulawak, lempuyang, ginger, bitter and turmeric, each in the same portion of 20%. A total of 40 laying hens aged 35 weeks are kept for one month.

Blood sampling was done at the end of the research to calculate the amount of erythrocytes, hemoglobin levels and hematocrit levels. The results showed hematocrit levels in chickens that were added additional herbs in the ration both at T1, T2 and T3 were different (P <0.05) with chickens that were not given additional herbs in the ration.
