Title : Enhancing zootechnical performance and resilience of whiteleg shrimp (litopenaeus vannamei) using phytogenic feed additives: A review of innate immunity, morphological characteristics, and histological responses to vibrio parahaemolyticus
Abstract:
Shrimp farming, particularly the Whiteleg Shrimp, Litopenaeus vannamei, holds a significant economic importance globally. However, the industry encounters challenges, including the risk of Vibrio parahaemolyticus infection and the need for sustainable farming practices. Phytogenic feed additives have emerged as a potential solution, with studies exploring their effects on zootechnical performance, immune response, and tissue health in L. vannamei. This review aims to summarize the existing studies on phytogenic feed additives in shrimp farming. Methodologically, a systematic search strategy was employed, focusing on growth performance, immune response, bacterial resistance, and histological responses of L. vannamei. The findings imply that phytogenic feed additives can enhance zootechnical parameters, such as growth rate and survival rate, while also improving innate immune responses through modulation of hemocyte count and antioxidant capacity. Histological evaluations reveal potential benefits in tissue health, particularly in the context of V. parahaemolyticus infection. However, variations in dosage, supplementation duration, and experimental conditions underscore the need for further research. Overall, this review highlights the promising role of phytogenic feed additives in promoting sustainable shrimp farming practices and identifies areas for future investigation.
