The effect of dietary inclusion levels of Origanum vUlgare as a feed additive compared with a control diet for 13 weeks on growth performance, feed utilization, whole body composition, entropathogenic Aeromonas hydrophila-challenge and economic efficiency for production of one Kg gain of Nile tilapia Oreochromi niloficus were stUdied. All experimental diets were iso-nitrogenous (30% crude protein) and iso-caloric (4.42 k caVg diet) with or without Origanum vulgare addition. Fifteen glass aquaria were used, each one was stoked with 15 fish (1.88±0.01gl fish) and three aquaria were designated for each treatment. The five treatments were: treatment 1 (was a control diet without additives), and four treatments (T2,T3,T4,T5) contained 0.5 %. 1.0 %,1.5 % and 2.0 % of Origanum vulgare respectively. Fish were fed on one of these experimental diets at feeding level of 8% of fish body weight for the first four ~eks then reduced to 5% for the next four weeks and then reduced to 3% for the remaining period of the experimental .The feed offered twice daily for six days per week. The results of this study revealed that, fish growth was increased gradually and the maximum growth was obtained when fish fed the diet contained! % of Origanum vulga/While the lowest growth was obtained from the control group. The highest feed intake and the best feed conversion ratio (FCR) were obtained when fish fed at 1% of Origanum vulgar.
