摘要

This study evaluated the efficacy of dietary banana stem powder (BSP) Musa cavendishii as a functional feed additive in enhancing the immune response, survival rate, and growth performance of Litopenaeus vannamei challenged with Vibrio parahaemolyticus AHPND. Shrimp were fed diets supplemented with 0.5, 0.6, and 0.75 g/kg BSP (BSP-0.5, BSP-0.6, BSP-0.75, respectively) for 30 days, followed by bacterial challenge. The group receiving 0.75 g/kg BSP exhibited the highest survival rate (93.33%) and significantly enhanced immune parameters, including total haemocyte count (THC), phagocytic activity (PA), phenoloxidase (PO), and respiratory burst (RB) (p < 0.05). Molecular analysis revealed significant upregulation of immune-related genes—LGBP, SP, and PE—corresponding with elevated immune responses (p < 0.05). Furthermore, growth performance improved notably in BSP-fed shrimp, with the lowest feed conversion ratio (FCR: 1.52 ± 0.12) recorded in the BSP-0.75 treatment. These findings suggest that BSP could serve as a sustainable, plant-based feed additive to support shrimp health and performance. However, further studies under commercial farming conditions are recommended to validate its efficacy, assess long-term impacts, and compare its effects with other established feed additives.
