Immune related transcriptional responses and performance of Litopenaeus vannamei post-larvae fed on dietary probiotic PrimaLac

The present study investigated the effects of various levels of multi-strain probiotic on the immune related gene expression, digestive enzyme activity, growth performance, body chemical composition and survival of Litopenaeus vannamei post-larvae. After transferring post-larvae of L. vannamei to indoor conditions and subsequent acclimation to laboratory condition for 14 days, the shrimp were fed multi-strain probiotic at four different doses of 0, 0.25, 0.5 and 1.0 g kg−1 for eight weeks. Shrimp fed 0.5 and 1.0 g kg−1 probiotic PrimaLac® exhibited significantly (p
