This study examined the effect of probiotic (Pediococcus acidilactici), sodium propionate salt and probiotic compound and sodium propionate salt on growth and expression of GH and IGF-I genes in common baby carp. For this purpose, 142 baby fishes (weighing approximately 14 g) for eight weeks were treated with four treatments of zero, 0.1% probiotic pseudococcal acidic acid, 1% sodium propionate, 0.1% pseudococcus acidic acid and 1% sodium propionate , Were classified and fed. This experiment was conducted in a completely randomized design. At the end of the biomarker period, there was a significant difference between treatments. The highest body weight gain (35.53 ± 0.47 g) and specific growth rate (3.5 ± 0.01) were observed in the third treatment (p <0.05). Also, the amount of food conversion factor (1.05 ± 0.07%) was observed in the third treatment (P <0.05). After sampling, GH expression in probiotic and sodium propionate salt treatments was significantly different with other treatments (P <0.05). Also, expression of IGF-I in probiotic and sodium propionate treatments was significantly different with probiotic treatment (P <0.05). Due to the beneficial effects of P. acidilactici, sodium propionate salt and probiotic compound and sodium propionate salt are clear on the expression of GH and IGF-I genes, it seems that the use of probiotic and sodium propionate salt in fish meals Ordinary carp can affect the growth and expression of GH and IGF-I genes in this species.
