| description | Acute Hepatopancreatic Necrosis Disease (AHPND) is a serious and emerging disease caused by a group of strains of <i>Vibrio parahaemolyticus</i> and affects farmed shrimp, particularly whiteleg shrimps (<i>Liptopenaeus vannamei</i>). The objective of this study is to assess the effect of dietary supplementation with two dosages of an essential oil mixture (Phyto AquaBiotic, abbreviated as PAB) on growth performance and mortality reduction after challenge against <i>V. parahaemolyticus</i>. PAB was mixed with basal diets at rates of 0, 1 and 2 g/kg and fed for 42 days. Each tank was stocked with 100 individuals with experimentation performed in triplicate. The results showed an improvement in growth performance in a dose-dependent manner, specifically regarding daily weight gain, specific growth rate and total biomass, which were significantly improved compared to control (<i>p</i> < 0.05). Further, PAB significantly reduced mortalities when challenged against <i>Vibrio parahaemolyticus</i> (<i>p</i> < 0.05) and decreased <i>Vibrio</i> spp. count in the hepatopancreas of infected shrimp. Overall, PAB was efficient in reducing mortalities in cases of disease outbreaks at a rate of 2 g/kg. |
