The main objective of this study was to evaluate the effect of different levels of chamomile oil (Ch), grape seed oil (GS), and antibiotic (colistin) (AN) as feed addetives on the productivity of growing rabbits. To achive this objective, a total of 96 New Zealand (NZW) weaned rabbits, 5 weeks-old were randomly allotted into eight groups. Rabbits were kept under observation for eight weeks and the trial ended at thirteen weeks-old. The experimental treatments were: 1) Basal diet (BD); 2) BD + antibiotic; 3) BD + 0.5 ml GS/ kg diet; 4) BD + 1.0 ml GS/ kg diet; 5) BD + 1.5 ml GS/ kg diet; 6) BD + 0.5 ml Ch/ kg diet; 7) BD + 1.0 ml Ch/ kg diet and 8) BD + 1.5 Ch/ kg diet. Live body weight (LBW) was markedly elevated (p < 0.05) in groups fed on ration included feed additives compared with the control at weeks 9 and 13 of age. Cumulative body weight gain (BWG) and feed intake (FI) increased (p < 0.05) throughout 5–9 and 5–13 weeks of age in rabbits fed rations plus the studied additives. Feed conversion ratio (FCR) was insignificantly altered by dietary feed additives. Spleen and intestine relative weights reduced (p < 0.05) in groups treated with different studied additives. In view of the experiment finings, it could be concluded that dietary supplementation of GS and Ch have a positive impact on the productivity of growing rabbits than that of the control and antibiotic-treated groups.
