<abstract xmlns="http://www.w3.org/1999/xhtml">The aim of this study was to evaluate the effects of different levels of dietary <italic>Lactobacillus plantarum</italic> as probiotic (Pro) with bovine lactoferrin (LF) and xylooligosacharide (XOS) on growth performance, hemato-immune response, body composition, digestive enzymes activity and expression of immune-related and growth-related genes of sobaity (<italic>Sparidentex hasta</italic>) for 8 weeks. Fish were fed with feed including: control diet (no LF, XOS and pro inclusion), diet 1 (400 mg kg−1 LF + 5000 mg kg−1 XOS), diet 2 (400 mg kg−1 LF + 10000 mg kg −1 XOS), diet 3 (400 mg kg−1 LF + 1 × 106 gr−1 Pro (<italic>L. plantarum</italic>)), diet 4 (800 mg kg−1 LF + 5000 mg kg −1 XOS), diet 5 (800 mg kg−1 LF + 10000 mg kg−1 XOS), diet 6 (800 mg kg−1 LF + 1 × 106 gr−1 Pro (<italic>L. plantarum</italic>)). Growth performance, hematological parameters (except for white blood cell counts), body composition and immune-related gene expression were not affected by different experimental groups (p>0.05). Nonetheless, non-specific immune response (except for total immunoglobulin) and growth-related gene expression of treatments and control group significantly varied (P&lt;0.05). Digestive enzymes activity including total protease and amylase increased by supplementing diets with different combinations of immunostimulants (P&lt;0.05).
