Abstract
The aim of this study was to assess the effect of garlic (Allium sativum) on growth factors, some hematological parameters and body compositions in rainbow trout (Oncorhynchus mykiss). A total number of 360 fish (average weight 20.88±0.25 g) was used. Fish were divided into four groups fed on diets containing garlic in different levels; 10 g kg-1, 20 g kg-1, 30 g kg-1 diet and the control group diet was without garlic. The experiment extended for two months. The results showed that, weight gain and growth performance of O. mykiss significantly (p<0.05) increased in all groups fed on garlic. There was significant decreases of plasma glucose in fish fed on diets containing garlic. Mean values of total plasma protein increased significantly in all treatments when compared to control group (p<0.05). Protein content and ash contents in fish body were significantly higher in the group fed on diet containing 30 g kg-1 diet of garlic than all other groups. Total lipids content in fish body decreased in treatments and it was lower in fish fed on 30 g kg-1 diet of garlic. The results of this study show that addition of garlic Allium sativum to fish diet can promote growth and improve fish health.
