Summary data from a proprietary company database are used to support relevant research findings.</div></div><div><h3>Synthesis</h3><div>Published literature supports the hypoth- esis that ruminant susceptibility to mycotoxin exposure poses a more significant hazard than historically assumed. Estimates of exposure have been restricted by testing pro- tocols and by failure to account for all potential toxin sources, additive and synergistic effects, and the effects of chronic low-level exposure. Mycotoxins can cause diverse short- and long-term negative outcomes with potential to reduce performance, efficiency, and health. Various my- cotoxin remediation products have been evaluated and employed. Although additional research is needed, it ap- pears that those combining proven, targeted sequestration agents with ingredients known to deactivate specific toxins or support the animal’s natural defense systems represent the most efficacious approach.</div></div><div><h3>Conclusions and Applications</h3><div>Continued improve- ment in mycotoxin awareness and management may allevi- ate a potential limiting factor in dairy and beef produc- tion. Broader assessment of actual animal exposure across a range of feeding programs and environments is needed to better understand mycotoxin hazards. Additional research should further clarify modes of action and metabolic im- pacts specific to ruminants, better quantify related production losses, and provide comparative assessments of specific remediation programs.</div></div>","PeriodicalId":8519,"journal":{"name":"Applied Animal Science","volume":"40 6","pages":"Pages 802-817"},"PeriodicalIF":1.4,"publicationDate":"2024-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143183457","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
