The aims of the present study were to investigate the effects of garlic at four levels including 0 (T0), 0.10 (T1), 0.15 (T2) and 0.20 (T3) gram of garlic essential oil per kilogram of diet on growth indices and survival rate, some blood biochemical parameters and digestive enzymes of dosatron d40mz2 zebrafish (Danio rerio).
The larvae were fed from the time of their first active feeding with experimental diets for 60 days.Results showed that the growth indices and survival rates of all groups fed with experimental diets containing garlic were significantly increased as compared to the control group blues cube (p0.05).According to the results of the present study, dietary supplementation of garlic had positive effects on improving the general condition, growth indices and activity of digestive enzymes of zebrafish.
