The aim of the present study was to investigate the antioxidant function of aloe vera gel, olive pomace, vitamin C, and vitamin E as a feed additive on gastro-intestinal functionality and integrity of growing rabbits.The study was carried on 48 New Zealand White rabbits (NZW) of 6 week old. The experiment lasted for 10 weeks. Rabbits were equally divided into 8 groups, (control) group which fed a basal diet, (A) group fed on a basal diet and water supplemented with Aloe vera gel at a dose (500mg/L), (C) group fed a basal diet and water supplemented with vitamin C(1g/4L), (E) group fed a basal diet and water supplemented with vitamin E (1ml/L), (O) group fed a basal diet to which 10% olive pomace was added, (CE) group fed a basal diet and water supplemented with both vitamins (C&E) by the previous doses, (ACE) group, its water supplemented with aloe vera gel ,vitamin C and vitamin E by the previous doses, (OCE) group fed the diet to which olive pomace and both vitamins in water with the previous doses was added. Performance parameters were measured live body weight (LBW), feed intake (FI) and feed conversion ratio (FCR) at the end of the experiment. Serum samples were collected to measure biochemical and antioxidant parameters. Tissue samples of duodenum were collected and prepared for histomorphological and molecular studies
