Some immune Responses of Raw Fiber (Vitacel) on Giant Sturgeon (Huso Huso)

The present study examined the effects of Vitacel raw fiber on great sturgeon (Huso huso) immunocompetent cell population size including lymphocyte and neutrophil populations and lysozyme activity after oral administration of the feed and Vitacel at 1.3% of the feed for 90 days. Generally, a significant increase was seen in the neutrophil count of fish receiving Vitacel as compared to the control group 90 days post treatment (P<0.05). Also, lysozyme activity in fish that received Vitacel was significantly higher than the control group 90 days post treatment (P<0.05). The results suggest that Vitacel may effectively promote immune responses in great sturgeon (Huso huso).
