Abstract: Rumen is a unique digestive organ of ruminants,housing a diverse variety of microorganisms that together form a complex and highly efficient micro-ecosystem. The normal functioning of the ruminal microbial fermentation is a crucial prerequisite for ensuring the health and production performance of ruminants. The contamination of mycotoxins in the feeds and forages for ruminants is relatively common,and these toxins primarily affect the rumen and its microbiota once ingested by ruminants,consequently impairing the digestive function and health of the animal. This review summarizes the research on the impact of various mycotoxins on the rumen fermentation and ruminal microbiome of ruminants,and discusses the potential related mechanisms based on relevant studies and evidences. The aim is to provide new insights for the prevention and control of mycotoxin-induced harms to ruminants.

Key words: mycotoxin, rumen fermentation, rumen microorganism, quorum sensing
