Abstract: In order to study the effect of Turmeric Rhizome Powder (TRP) on immunity responses in broiler chickens, in a completely randomised design, an experiment with 200 day-old Ross male broiler chickens from 0-49 days with 4 treatments and 5 replicates of 10 birds each was conducted. A corn-soybean meal based diet containing levels of TRP (0.00, 0.25, 0.50 and 0.75%) was used. For measuring immunity responses (white blood cell, immunoglobulins A, G and M), at 14 days of age, one bird from each replicate of treatments was challenged with 0.2 mL Sheep Red Blood Cell (SRBC, 5%) and blood samples were collected at 21 and 42 days of age. Inclusion of TRP significantly (p< 0.05) increased immunoglobulins IgA, IgM and IgG (IgY). TRP inclusion into the diets also significantly decreased the ratio of monocytes at 42 days of age (p< 0.05). Under the condition of this study, it was concluded that TRP might have some positive effects on immunity response and may be used as immune system fortification in broiler chickens.
