Effects of supplemental dietary blend of humic substances and butyric acid plus yeast cell walls on immunity and resistance to bacterial coinfection in juvenile Channel Catfish

Feeding Channel Catfish with a dietary humic substance and buryate blend reduced the susceptibility of Channel Catfish to E. ictaluri and coinfection with F. covae. These research findings have potential practical implications for fish health and provide an alternative tool for the management of coinfections in the catfish industry.
