Abstract: In recent years, with global warming and the frequent occurrence of extreme weather events, mold infections in crops and livestock feed have become increasingly severe. Mycotoxins are toxic metabolites produced by molds during their growth, which widely contaminate agricultural products and animal feed and exert strong toxic effects. Among livestock, pigs are the most sensitive to mycotoxins. When pigs ingest feed contaminated with different mycotoxins, they can suffer multi-system damage, including to the digestive, immune, and reproductive systems. One of the most typical and common clinical symptoms is anorexia or food refusal in pigs, which seriously affects their growth performance. Pig appetite is regulated by multiple factors. Different mycotoxins cause varying types of damage to pigs and suppress their appetite through different pathways. This article provided a comprehensive review of the regulatory mechanisms and potential hazards of different mycotoxins in pigs, aimed to explore the differences and commonalities among them, offer new breakthroughs for the prevention and control of mycotoxins, and provide reference for healthy livestock farming and the development of related products.

Key words: mycotoxin, appetite, pig, induce, toxic mechanism, prevention and control measure
