Evaluation of Bacillus licheniformis and Bacillus subtilis as probiotic and Fe ion effects on haematological parameters of rainbow trout, Oncorhynchus mykiss frys

In conclusion, the high levels of WBCs and IgM are likely an immunity response to probiotic. Low levels of RBCs, Hct and Hb likely return to low levels of serum in treatments fed by diet without feriron solution. It seems that the Fe ion causes the proliferation of probiotic bacteria and in return probiotics help to digestion and subsequently the bioavailability of elements including Fe ion to serum.
