Review demonstrates improved gut health and immunity in aquatic species fed tributyrin, suggesting enhanced viability for sustainable plant-based feeds.
Aquaculture faces increasing challenge related to plant-based diets and the sustainability of feed ingredients. Tributyrin, a triglyceride ester of butyric acid, has gained attention as a functional feed additive in aquaculture due to its potential to enhance gut health, immunity, and metabolic performance in various aquatic species. Tributyrin offers a promising solution by improving nutrient absorption, promoting immune responses, and supporting digestive health. While the effects of tributyrin in shellfish remain underexplored, theoretical benefits suggest that it may enhance digestive efficiency and stress resistance. This review highlights the promising role of tributyrin in aquaculture, particularly in promoting sustainable feed practices, while calling for more targeted research to determine its effectiveness across a wider range of species and environmental conditions.
