Description
Belfiore and co-authors feed young rainbow trout diets laced with tiny capsules holding three plant-based additives, checking whether the capsule coat keeps them active through feed making. The additives are rosemary oil, a red pigment called astaxanthin, and butyric acid. Over ninety days, the 2026 trial tracked growth, gut and liver health, stress markers, and fillet traits against plain feed.
All three supplemented groups outgrew the controls, with no harm seen in tissues. Rosemary held fillet protein steady, the pigment enriched fat and color, and butyric acid gave leaner fillets with more protein laid down. Blood antioxidant enzymes ran lower in supplemented fish, hinting at calmer internal chemistry. Fillet acidity also held steadier after freezing in two groups. The authors back coated additives for trout farms.
