Deoxynivalenol (DON) is the most common mycotoxin contaminant of cereal-based food and animal feed. The toxicity DON very low compared to that other toxins; however, prominent signs exposure include inappetence body weight loss, which causes considerable economic losses in livestock industry. This review summarizes critical studies on biological mitigation strategies respective vitro vivo intestinal effects. Focus areas growth performance, gut health terms histomorphology, epithelial barrier functions, immune system microflora, short-chain fatty acid production intestines. In addition, detoxification modulation these parameters, through supplements, are discussed. Biological using microorganisms can attenuate by modulating microbiota improving with or without influencing performance pigs. However, use as feed additives for mycotoxins needs more research before commercial use.

Fungi are ubiquitous organisms that thrive in diverse natural environments including soils, plants, animals, and the human body. In response to warmth, humidity, moisture, certain fungi which grow on crops harvested foodstuffs can produce mycotoxins; secondary metabolites when ingested have a deleterious impact health. Ongoing research indicates some mycotoxins and, more recently, peptide toxins also produced during active fungal infection humans experimental models. A combination of innate adaptive immune recognition allows host eliminate invading pathogens from However, imbalances homeostasis often facilitate microbial infection. Despite wide-ranging effects health, our understanding toxin-mediated modulation responses is incomplete. This review will explore current how they contribute immunity.

Aflatoxin B1 (AFB1) is a common mycotoxin that widely occurs in feed and has severe hepatotoxic effects both humans animals. Total flavonoids of Rhizoma Drynaria (TFRD), traditional Chinese medicinal herb, have multiple biological activities potential hepatoprotective activity. This study investigated the protective mechanisms TFRD against AFB1-induced liver injury. The results revealed supplementation with markedly lessened broiler intestinal permeability by increasing expression tight junction proteins, as well correcting changes gut microbiota damage induced AFB1. Metabolomics analysis alterations plasma metabolites, especially taurolithocholic acid, were significantly improved treatment AFB1-exposed chickens. In addition, these metabolites closely associated [Ruminococcus], ACC, GPX1, indicating AFB1 may cause injury inducing bile acid metabolism involving microbiota-gut-liver axis. We further found suppressed oxidative stress hepatic lipid deposition, increased glutathione (GSH) concentrations, reversed ferroptosis gene expression. Collectively, findings indicate might contribute to hepatotoxicity chickens through axis interaction mechanisms; furthermore, was confirmed an herbal extract could potentially antagonize mycotoxins detrimental effects.
