The relative gene expressions of antimicrobial peptide system in shrimp haemocyte after feeding polyamine CQD containing-feed, evaluated by real-time PCR. (a) ALF, (b) Crustin, (c) Lyz, (d) PEN2, (e) PEN3 and (f) PEN4 gene expressions in shrimp haemocyte. The experiment was repeated three times. Each bar represents the mean ± SD. Significant differences (p < 0.05) of gene expression level between the compared groups are indicated with one asterisk. Double asterisks indicate very significant difference (p < 0.005).
