Improvement of the immunological and antioxidant capacity of rainbow trout (Oncorhynchus mykiss) by using the paraprobiotic Bacillus subtilis subsp. spizizenii

The aim of this study was to produce Bacillus subtilis subsp. spizizenii as a paraprobiotic for the nutrition of rainbow trout (Oncorhynchus mykiss). Fifty-four trout (74.51 ± 3.15 g) were transferred to nine 300-liter tanks and fed PRO (live freeze-dried form), PAR (irradiated freeze-dried form) an...

Description
Summary:The aim of this study was to produce Bacillus subtilis subsp. spizizenii as a paraprobiotic for the nutrition of rainbow trout (Oncorhynchus mykiss). Fifty-four trout (74.51 ± 3.15 g) were transferred to nine 300-liter tanks and fed PRO (live freeze-dried form), PAR (irradiated freeze-dried form) and control feed (n=3) for 8 weeks. Growth, hematological, immunological and enzymatic liver functions, as well as antioxidant capacity were then analyzed. Kidney, liver, and intestinal tissue as well as the expression of cytokines (TNF-1, TNF-2, IL-1β1, and IL-1β2) in spleen, and kidney were analyzed. The growth indices, white, and red blood cells, neutrophils, monocytes and granulocytes, total protein and globulin improved in the PAR and PRO groups compared to the control group (p
