Feeding-Regime-Dependent Intestinal Response of Rainbow Trout after Administration of a Novel Probiotic Feed
Original language description
In this study, we tested the autochthonous trout probiotic strain L. plantarum R2 BiocenolTM in a newly developed low-cost application form ensuring rapid revitalization of bacteria. We tested the continuous and cyclic feeding regime with regard to its effect on the intestinal immune response and microbiota of rainbow trout. We found that during the continuous application of probiotic feed, the immune system adapts to the immunomodulator and there is no substantial stimulation of the intestinal immune response. On the other hand, after a 3-week break in probiotic feeding and reintroduction of probiotics, there was a significant stimulation of gene expression of molecules associated with both cellular and humoral immunity (CD8, IgM, TGF-β, IL8, TLR9), but without a significant increase in the basic pro-inflammatory cytokines IL1 and TNF-α. We can conclude that in aquaculture it can be used as a continuous application, which does not cause excessive immunostimulation, as well as a cyclic application, which provides the opportunity to stimulate the immunity of trout, for example, in periods of stress. The newly developed application form proved to be suitable, as the fish accepted it without any problems.
