Abstract

This study investigated the effects of different levels of synbiotic Biomin Imbo in the diet on growth performance, food efficiency, survival, digestive enzymes activity and some mucus immunological indices of banded cichlide. The experiment designed using a completely randomized test in a control (0 g synbiotic) and 5 treatments, including 0.5, 1, 1.5, 2 and 2.5 g/Kg synbiotic diet, any group with 3 replicates and 15 fish per treatment for 60 days. The results of this study showed that the addition of 0.5 g/Kg synbiotic in diet hadn't significant effect on growth parameters and feed efficiency (P>0.05). However, higher levels of Biomin Imbo synbiotic on diets significantly increased growth parameters such as final weight, percent of body weight, daily growth rate (SGR) and feed efficiency parameters such as feed conversion ratio (FCR) and protein efficiency ratio (PER) (P<0.05). Fish fed dietary with synbiotic showed significant changes in non-specific skin mucus immune parameters, including lysozyme, total protein and alkaline phosphatase (P<0.05). Eventually results of this study showed that synbiotic Biomin Imbo have the beneficial effects on metabolism and growth of banded cichlide, also it increases the safety of juveniles and increase the survival of this fishes.
