Ochratoxin a(OTA)is a type of mycotoxin that has a wide range of contamination and widely exists in wheat,corn and other feed ingredients.After absorbed from the gastrointestinal tract,OTA diffuses to the liver and kidney through the circulatory system of animals,causing nephrotoxicity,hepatotoxicity,enterotoxicity,immunotoxin,carcinogenicity and teratogenicity and other toxic effects to livestock and poultry,thus causing serious harm to the health and production of livestock and poultry.Therefore,it is urgent to study how to alleviate the toxic effect of OTA.Biological mitigation strategies mainly included microbial mitigation measures such as yeast,Bacillus and enzymatic degradation measures.In addition to biological mitigation,nutritional mitigation measures including plant extracts,vitamins,trace elements,amino acids,etc.,which can also have a good mitigation effect on OTA toxicity.The authors summarize the toxic effects of OTA on livestock and poultry,and focuse on the research progress on biological and nutritional mitigation strategies to alleviate the toxic effects of OTA,in order to provide a reference for alleviating the harm of mycotoxins to the healthy breeding of livestock and poultry and promoting the high-quality development of livestock and poultry.
