Monolaurin in feed boosts growth and gut health in juvenile largemouth bass

Dietary monolaurin is earning its place in aquafeed, and the data from juvenile largemouth bass makes a compelling case. Across 56 days, fish fed 800 to 1100 mg/kg showed higher final body weights, with 800 mg/kg delivering the best growth rates. Beyond size, the additive lowered whole-body lipid content while boosting crude protein, and it sharpened antioxidant defenses by raising catalase and superoxide dismutase activities. Gut health followed suit, as pathogenic *Aeromonas* declined while beneficial *Cetobacterium* flourished.
