Evaluation of commercial procell Rand selmanexR product supplements effect on growth performance body composition 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 and selmanex 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). Results showed that administration of two products saccharomyces cerise groups had insignificant effects on the growth performance (P < 0.05). Effect on the specific growth rate (SGR) and feed utilization efficiency of C. carpio. There was no significant difference between the three experimental groups. But the carcass protein content was higher in Procell group than in the other two groups (P> 0.05). Possibly, procell commercial product could be more effective than Selmanex in promoting growth and improving the quality of carcasses in juvenile carps.
