Abstract
ABSTRACT The work focused on the study of the immunomodulatory and gut-protecting effect of humic substances (HS) in broilers. The diet of experimental chicks was enriched with 0.8% of HS. We noted that HS had a stimulatory effect on the phagocytic activity and the engulfing capacity of phagocytes, however, the level of oxidative burst of phagocytes was not affected. We observed a significant increase of CD4+: CD8+ lymphocyte ratio, an indicator of immune stimulation. HS did not influence the IgA gene expression. In contrast, we observed a significant increase in the expression of MUC-2 (intestinal mucin 2) gene, and a decrease in the expression of IGF-2 (insulin-like growth factor 2) and also AvBD2 (avian beta defensin 2) genes. A decreased Enterobacteriaceae counts in the gut of experimental animals showed a positive effect on intestinal microbiota. We confirmed a gut-protecting and an immunostimulatory effect of HS in broiler chickens.
