Effects of Supplemental Feeding of Common Carp (Cyprinus carpio) with Iron Nanoparticles and Probiotic Lactobacillus on Blood Biochemical Factors

The purpose of this study was to investigate the effect of commercial Lactobacillus probiotic and iron nanoparticles on some blood biochemical parameters of common carp ( Cyprinus carpio ). Common carp (mean weight 50 g) was fed in six treatments with 0.25 and 0.50 mg/g iron oxide nanoparticles and 10 8 CFU/g commercial Lactobacillus probiotic either together or separately for 56 days. After the rearing period, blood biochemical parameters including total plasma protein, albumin, globulin, creatinine, triglyceride and cholesterol and ALP, ALT, AST and LDH enzymes were measured. Total protein and globulin levels showed a significant increase in probiotic alone and probiotic plus 0.50 mg iron nanoparticles treatments ( p ≤ 0.05). Creatinine, albumin, liver enzymes, serum lipids did not show any significant differences between treatments ( p ≥ 0.05), but the values of these parameters showed no negative effects in different treatments. Based on the findings of this study, it can be concluded that using iron nanoparticles and Lactobacillus probiotic can improve some of the biochemical factors in carp.
