TL;DR
This study shows that adding microencapsulated botanicals and organic acids to gilthead seabream diets improves their growth and immune health.
Contribution
The study is the first to explore the use of microencapsulated OA+B in aquaculture for enhancing fish health.
Findings
OA+B supplementation increased growth performance and specific growth rate in gilthead seabream.
OA+B improved humoral and cellular immunity in both in vitro and in vivo experiments.
Gene expression analysis showed positive modulation of immune-related genes and oxidative stress response.
Abstract
For their ability to enhance performance, immune response, and robustness to environmental stressors in both fish and crustaceans, phytogenic compounds are receiving increasing attention from the aquaculture industry as alternatives to traditional feed additives. Numerous studies have investigated the use of a specific combination of organic acids and botanicals (OA + B) in terrestrial animals, but their potential role in aquaculture remains unexplored. The objective of this study is to assess the feasibility of a blend of OA + B (microencapsulated in a lipid matrix; AviPlusAqua – Vetagro S.p.A.) to enhance the health of gilthead seabream. To better assess the potential of the selected blend, both in vitro and in vivo experiments were conducted. Head‐kidney leukocytes (HKLs) were incubated with varying doses of OA + B, then viability and cellular immune parameters were evaluated after…
