Abstract
    This study was conducted to determine the effect of dietary level of vitamin E on growth performance of ornamental Japanese carp Cyprinus carpio. The experiment was carried out with four experimental variants carp in duplicate aquaria for 102 days. In V1 variant was used a comercial diet with 240 mg vit E/kg. In other variants, basal diet was supplemented with 100, 200 and 300 mg vitamin E / kg (variant 2 - V2, 3 - V3 and 4 - V4). Within the experimental period, the fishes were fed 3 times a day manually at initially rate of 10% of their body weight and then progressively decreasing. All fish from each replicate were weighed at the beginning and every two weeks until the end of the experiment. The effects of feeding through E vitamin in different proportions on the parameters such as growth in view of live weight, survival rate, feed conversion, specific growth rate, protein efficacy for the ornamental carp were studied. The best results regarding growth were obtain in V1 and V2 variants in which was used 240 and 340 mg / kg diet respectively of vitamin E.

Key words: ornamental carp, vitamin E, weight gain, feed conversion ratio, specific growth rate
