The present study was performed to evaluate the effect of different levels of BetaPlus probiotic and Technomus prebiotic on growth indices, survival and body composition of Litopenaeus vannamei shrimp grown in Caspian Sea water. Seven groups of shrimps with an average weight of 4.02 ±0.12 g in fiberglass ponds with a density of 30 shrimps in each pond, for 56 days with different levels of betaplus (0.1 and 0.2% of feed, each treatment With 3 replications) and technomus (0.1 and 0.2% of food, each treatment with 3 replications) and a combination treatment (with a combined dose including BetaPlus with a dose of 0.1 and Technomus with a dose of 0.1) and a combination treatment The others (with a combined dose including Betaplus with a dose of 0.2 and Technomus with a dose of 0.2) were fed. At the end of the period, growth indices (mean body weight gain, body weight gain percentage, feed conversion ratio and specific growth rate), survival percentage and body composition of these treatments were compared with the control treatment. The results showed that the treatment fed with 0.2% beta-plus and technomus levels had better growth indices and higher survival than other treatments (P <0.05). Examination of body chemical composition showed that there was a significant difference in protein content between the 0.2% treatment and the control treatment, although there was no significant difference in the percentage of fat, ash and moisture between different treatments (P>0.05). Based on the results of this study, the use of 0.2% level of Betaplus and technomus in the diet of white shrimp is recommended to improve growth performance, survival and body composition.
