The study below aimed at examining the effect of dietary supplementation with cinnamon and garlic powder on growth performance and immune response of catfish larvae at 3-28 dph. A total of 500 catfish larvae (0.05g ABW) were randomly assigned to three treatments for 30 days feeding period; group I (control group) received normal basal diet, group II (Cinnamon group) fed with basal diets containing 1% and 5 % cinnamon powder, and group III (Garlic group) fed with basal diets containing 1% and 5 % garlic powder at a rate of 7% of their body weight. Growth performance, length, percentage feed efficiency, feed conversion ratio, mean weight and survival were determined. Results: Results of this study revealed that dietary supplementation with 1% garlic significantly increased the final body weight and percentage weight gain followed by group fed 1% cinnamon compared with control group fed basal diet only (P=0.21). SGR, FE, and FCR in cinnamon and garlic groups recorded a significant variance in comparison with the control. In addition both cinnamon and garlic groups showed significant increase in survival of the catfish larvae in comparison with control group.
