dc.description.abstractTraditional Vietnamese herbal species were examined for their antimicrobial activity and disease resistance in whiteleg shrimp. In-vitro screening, the extracts of ten herbs were conducted to test the inhibition ability against <em>Vibrio parahaemolyticus</em>, causing acute hepatopancreatic necrosis disease. The results showed that five out of ten herbal species, including <em>Pithecellobium dulce</em>, <em>Melaleuca leucadendron</em>, <em>Eucalyptus globulus</em>, <em>Mimosa pirga</em>, and <em>Hibiscus sabdariffa</em> displayed potent antibacterial activity. Besides, three types of extracts of <em>H. sabdariffa</em>, <em>E. globulus</em>, and <em>M. pirga</em> were coated to the pellet feed at a concentration of 1%. After 30 days of feeding, the whiteleg shrimp (<em>Penaeus vannamei</em>) were challenged by <em>V. parahaemolyticus</em> through immersion. The growth performance (such as growth rate in length and weight, survival rate), hematological parameters of total hemocytes (THC), hyaline hemocytes (HC), and granulocytes (GC), and hepatopancreas recovery under the treatments with herbal extracts of the whiteleg shrimp were significantly enhanced as compared with the control (without herbal extract). The mortality and the bacterial density in the hepatopancreas of shrimp decreased. Specifically, the mortality of shrimp in the treatment supplemented with the methanol extract of <em>H. sabdariffa</em> was the lowest, followed by <em>M. pirga</em> and <em>E. globulus</em>. The experimental results also indicated that <em>H. sabdariffa</em>, <em>E. globulus</em>, and <em>M. pirga</em> could improve immune parameters and disease resistance; therefore, they should be employed in sustainable shrimp, practical farming.
