Results of the experiment revealed that live body weight (LBW) and total body gain (TBG) were significantly higher (P< 0.05) and feed conversion ratio (FCR) was the best with rabbits fed basal diet plus Nano-Se compared to those fed the control diet or rabbits fed basal diet plus Org-Se. However,with adding Vit. E to the basal diet, the differences in these traits were not significant among the rabbit groups.
Selenium concentrations in kidneys, liver, muscles and blood serum were insignificantly higher in rabbits fed supplemental Nano- Se than in those fed basal diet without any supplementation (control) or those fed
