摘要

Coriandrum sativum (commonly known as coriander) is a promising natural feed additive for enhancing the growth and well-being of aquatic species because of its antibacterial, anti-inflammatory, and antioxidant qualities. This study investigated the effects of dietary supplementation with coriander ethanolic extract (CEE) on growth performance, nutritional composition, immune response, and disease resistance in Macrobrachium rosenbergii against Vibrio parahaemolyticus. Initially, 135 juvenile prawns (2.1 ± 0.25 g) were assigned to three dietary groups in triplicate (15 prawns/tank) including a basal diet (control), 0.25% or 2.5 g/kg CEE1 (T1), and 0.5% or 5.0 g/kg CEE2 (T2). Following eight weeks of feeding at 5% of body weight, the growth, immunological characteristics, nutritional composition, and digestive enzyme activity were assessed. Then prawns were challenged with V. parahaemolyticus (106 CFU/mL), and survival rate was monitored for 14 days. The CEE group demonstrated significantly superior growth parameters, including final weight (FW), average weight gain (AWG), specific growth rate (SGR), feed conversion ratio (FCR), protein efficiency ratio (PER) (p < 0.05), nutritional value (percentage of protein, lipid and ash) and enzymatic activity (Amylase, Protease) compared to control (p < 0.05). Immune-related parameters such as total haemocyte count (THC), superoxide anion production, respiratory burst (RBs), pro-phenoloxidase (proPO), and superoxide dismutase (SOD) activity were significantly elevated in CEE supplemented groups both pre- and post-challenge. After 14 days of challenge, CEE2 exhibited the highest survivability (70%) compared to CEE1 (50%) and control (0%) (p < 0.05). According to these results, 0.5% CEE supplementation had the highest growth, immunological response, and disease resistance, making it a viable feed additive in aquaculture. Therefore, this study highlights the efficacy of CEE in sustainable aquaculture, providing a natural solution to improve production and health in aquatic organisms.
