In recent years, the use of probiotics has been considered as an ecological preventive approach to aquaculture, because of the perilous consumption of antimicrobials for humans and the environment, the use of alternative methods is increasing. In this study, we compared the efficacy of different methods of preparation of functional food containing native probiotic Takcell® on the growth performance of juvenile western white shrimp. For this purpose, post larvae of shrimps were fed in 8 experimental treatments in two ways: probiotic Supplemented and sprayed diets at doses of 108, 107, and 106 CFU kg-1 and probiotic-free diets for 40 days in tanks. All probiotic fed- diets showed better performance in relative growth rate, specific growth rate, survival rate and feed conversion ratio compared to control groups (p<0.05). The highest activity of growth indices was observed in spray treatment at a dose of 108 CFU kg-1. There was no significant difference with complementary diets (p>0.05). The results of this study showed that functional food containing native probiotic Takcell®, regardless of doses and preparation methods, resulted in improvement of growth and survival indices in western white shrimp, and the dose of 108 and 107 CFU kg-1 had the highest effect.
