Hernández, B. García García, M. Caballero, M. Hernández] Gilthead seabream (Sparus aurata) were fed a basal (control) diet and four experimental diets (R600, R1200, R1800 and R2400), containing 600, 1200, 1800 and 2400mgkg−1, respectively, of rosemary extract (Rosmarinus officinalis L.). At 4 and 12weeks from the beginning of the ongrowing period, the fish were sacrificed, blood was drawn to obtain plasma and the liver and intestines were dissected. Growth and feed intake were unaffected by rosemary extract addition. A histological examination of the intestine revealed no differences among the dosages, while the liver showed a sharp decrease in hepatic steatosis in diets supplemented with rosemary extract. Furthermore, plasma alanine aminotransferase was lower with these diets at the end of the ongrowing period. Rosemary extract reduced the plasma levels of glucose and triglycerides on week 4 and glucose and HDL/LDL cholesterol ratio on week 12, suggesting better transport and energy metabolism of the lipids. Overall, the most evident effect of rosemary extract was observed with the 600mgkg−1 dose.
