The present experiment was conducted to investigate the effects of adding graded levels (0, 0.15, 0.45, 0.3 and 0.6%) of garlic (Allium sativum) to the basal experimental diet on the broiler chicks growth performance and immune response. One hundred and fifty unsexed Ross broiler chicks were randomly distributed; 30 birds/dietary treatment and each treatment contained 3 replicates (10 birds/replicate). The results showed significant (p<0.05) improvement in feed conversion ratio of birds fed 0.3% garlic. The mortality rate followed the same trend of feed conversion ratio. Weight gain was found to be increased by inclusion of garlic, but was not statistically significant. Total White Blood Cells (TWBC) of birds fed 0.3% garlic was significantly (p<0.05) higher compared to these fed other dietary treatments and the lower TWBC was recorded by the control treatment. No significant differences in blood serum total protein, albumen and globulin were observed. Colour, flavour, tenderness and juiciness of sensory evaluated samples were not statistically different.
