Evaluation of commercial prosell and selmanex product supplements effect on the immunological and hematological parameter of common carp (Cyprinus carpio)

Yeasts are among the commonly used aquatic cultures that have high nutritional value, contain vitamin B, pigment, protein and carbohydrates, and are considered an important ingredient in the aquaculture industry. Meanwhile, Saccharomyces cerevisiae has various immune stimulants such as glucans, nucleic acids, mannan oligosaccharides and chitin. Various studies have shown the positive effect of this prebiotic on these fish. Effects of dietary supplementation of commercial procell andselmanex on the growth performance, immunity, biochemical factor serum and body composition of juveniles C. carpio, were evaluated. For this purpose, 180 juveniles C. carpio (mean body weight 20 gr) randomly were divided into 4 equal groups (three replicates each). The results showed that both products were no significant difference with hematological parameters such as hemoglobin, hematocrit, red blood cell and white blood cells. Results showed that dietary administration of procell significantly increased the serum lysozyme and complement activity, and respiratory burst activity in C. carpio at days 60th of the experimental period. The highest bactericidal activity (P<0.05) was observed in the fish, which fed a diet containing procell. Possibly, procell commercial product could be more effective than selmanex in promoting the innate immune system and improving the quality of health in juvenile carps
