Abstract :

In this study, the effect of Sabrzard extract (Aleo vera) on growth of  Shyrbot (Barbus grypus) were investigated. For this purpose three concentrations of Aloe vera extract, 0.1, 0.2 and 0.5% (in triplicate) were mixed with the feed and the fish were fed with this diet for 60 days. Control group was fed with the control diet without Aloe vera extract. Growth parameters include weight gain, percent of weight gain, increase of length, condition factor, feed consumption, feed conversion, specific growth rate, protein efficiency ratio and food efficiency were measured. Results indicated that  feeding Shyrbot with Aloe Vera extract 0.2% lead to significant increase in the quality index, percent of weight gain, specific growth rate and weight gain (P<0.05). Also feeding with extract 0.5% lead to increase of quality index (P<0.05). Effect of oral administration of different doses of Aloe vera on feed conversion, protein efficiency ratio, feed efficiency comparison between treatments and control group was different significantly (P<0.05). Altogether we can say that the better doses of Aloe vera in diet for growth excitement and blood parameters are 0.2 and 0.5%.
