Abstract
Eight experimental diets containing different levels of ochratoxin-A (aCTA) being 0, 4.8, 9.6 and 14.4 mg I kg diet with (3 g blogen/Kg diet) or without biogen were fed to Nile tilapla (Oreochromis niloticus) fingerlings to determine their effects on growth performance, feed utilization and carcass composition. These diets containing 30 % crude protein were fed to duplicate groups of tilapia (3.6 glfish) at a daily feeding rate of 3%of the body weight. The results showed that increasing aCTA levels in the diet resulted In decreasing growth performance and feed utilization parameters. However, addition of biogen to the diets enhanced the growth performance, feed utilization and reduced the negative 6ffects of aCTA on the same parameters. Carcass dry matter, protein and ash contents were negatively correlated with aCTA levels however, carcass lipids and gross energy content had positively correlated with OCTA levels. Supplementation of diets with blogen reduced carcass lipid content than wtthout biogen. Finally, It could be concluded that OCTA reduced growth performance and feed utilization of tilapia, however, blogen Improved the above mentioned criteria.
