Abstract

The effect of feed additive including antioxidant dihydroquercetin and polysaccharide arabinogalactan on the activity of metabolic enzymes in muscles and liver of artificially grown rainbow trout Oncorhynchus mykiss Walb., affected by bacterial infection,was investigated. The results of the study indicated an increase in the resistance of trout to the action of bacterial infection with the enrichment of the diet with the studied bioactive components, including, apparently, through the activation of metabolic pathways of synthesis of energy and reducing equivalents.
