This study aimed to determine the effect of turmeric powder (Curcuma domestica Val) in feed on the blood of local ducks. The study used 80 head day old duck (DOD), Pitalah male duck, which wasplaced on the 20 unit enclosure plot, with 4 treatments and 5 replications. The treatments given are A (feed + 0.0% turmeric powder), B (feed + 0.2% turmeric powder), C (feed + 0.4% turmeric powder) and D (feed + 0.6% turmeric powder). The parameters measured were the number of erythrocytes, hemoglobin concentration, and hematocrite percentage, the number of lymphocytes, heterophile, monocytes, eosinophil and basophils. Data obtained during the 11-week maintenance period were analyzed using analysis of variance based on a randomized block design (RBD), followed by Ducan's Multiple Range Test (DMRT). Giving turmeric powder (Curcuma domestica Val) up to 0.6% very significant increase (P<0.01) the number of erythrocytes, hemoglobin concentration, hematocrit and total lymphocyte persentasse, while the number of heterophile, monocytes, eosinophils and basophils real decrease (P<0.05). The study states that the using of turmeric powder (Curcuma domestica Val) up to 0.6% in the diet can improve health status have shown the blood conditions.
