Enhancement of Innate Immunity in Common Carp Cyprinus carpio Using local Probiotic

Abstract

The objective of this study was to determine the effect of four levels of local probiotic compared with commercial probiotic on immune status of common carp Cyprinus carpio as biological control. One handared and eight speciement of Cyprinus carpio average weight of 57.85±0.3g were fed during 42 days at 0.05,0.1,0.5 and 0.75mg local probiotic per Kg diet compared with 2mg commercial probiotic per Kg diet in comparison with the control group without additive. The phagocyctic index of blood macrophages, reduction of nitrobluetetrazolium (NBT) by radical oxegen produce from neutrophils cell ,and alternative complement pathway (ACP) activities were evaluated. A positive correlation was found between the levels of phagocytosis, nitrobluetetrazolium index and alternative complement pathway activities in blood and the level of inclusion of local probiotic compared with commercial probiotic and control group.
