| Abstract |
| Purpose: An In vivo study was conducted to improve growth performance and some immunity parameters in zebrafish (Danio rerio) larvae. Method: To promote the immunity factors and growth indices, zebrafish larvae fed with supplementary diets with a new synbiotic consisting Lactobacillus casei as probiotic and banana peel as prebiotic sources. The larvae (60 ± 1.0 mg) were fed for 8-week period on different supplementation diets as follows: Control (basal diet), 1% banana peel powder (prebiotic diet), 107 CFU g-1 L. casei (probiotic diet), 107 CFU g-1 L. casei + 1% banana peel powder (synbiotic diet). At the end of the trial, growth performance, survival and innate immune responses were evaluated by completely random sampling. Results: Growth performance was significantly improved in fish fed with supplemented diets (P < 0.05). No significant differences of survival were observed between the different treatments as compared to control (P > 0.05). Furthermore, innate immune parameters were enhanced in fish fed diet supplemented synbiotic in comparison with control group (P < 0.05). Conclusions: Altogether, these results indicated that L. casei combined with banana peel powder as an efficient symbiotic can improve the growth and innate immune parameters in zebrafish (Danio rerio). |
