Kainbow trout were fed two cxperimental diets diffcrcd in lipid content by replacement of crude starch (lipid-poor diet : 4.2% lipid or lipid or lipid-rich diet : 14.8% lipid) supplcmented or not with antibiotics (a combination Flumcquine + Gentamycin, 1:4). The apparent digestibility of dry matter, crude protcin, lipid, carbohydratc and total energy werc measured. Addition of lipid by replacement of crude starch in the fish diet in the absence of antibiotics cnhanced significantly (p
