Summary
This study investigates the effects of dietary lysophospholipid supplementation on the physiological and microbial health of Pacific white shrimp (Litopenaeus vannamei), a commercially significant aquaculture species. It likely demonstrates that lysophospholipids, as emulsifying feed additives, can modulate antioxidant defence systems, enhance digestive enzyme activity, and shift the composition of intestinal microbiota in shrimp. The findings contribute to understanding how lipid-based feed additives may improve gut health and nutritional efficiency in intensive shrimp aquaculture systems.
UK applicability
The UK has a limited Pacific white shrimp aquaculture sector, so direct applicability is narrow; however, findings on lysophospholipid supplementation as a feed additive strategy may be of interest to UK aquafeed researchers and the broader European aquaculture industry seeking to optimise digestive health and reduce antibiotic use in farmed species.
Key measures
Antioxidant enzyme activity (e.g. SOD, CAT, T-AOC); digestive enzyme activity (e.g. lipase, protease, amylase); intestinal microbial diversity indices; feed conversion ratio
Outcomes reported
The study measured antioxidant enzyme activity, digestive enzyme performance, and intestinal microbiota composition in Litopenaeus vannamei (Pacific white shrimp) following dietary lysophospholipid supplementation. It likely reports changes in oxidative stress markers, nutrient digestibility, and microbial community structure across treatment groups.
