摘　　要：霉菌毒素主要是由曲霉菌、青霉菌或镰刀菌类等真菌产生的次级代谢产物,它们是人类和动物食物中最常见的天然食品污染物。摄入受霉菌毒素污染的食物会引起以急性死亡、生殖紊乱、生长障碍和对传染病的抵抗力降低等为特点的毒理学改变。此外,霉菌毒素还具有致畸、致癌和致突变的风险。为促进动物的健康养殖,该文将对现阶段饲料霉菌毒素导致动物肠道功能异常的机制研究进行介绍。Mycotoxins are mainly secondary metabolites produced by fungi such as aspergillus,penicillium or fusarium.They are the most common natural food contaminants in human and animal food.Ingestion of food contaminated with mycotoxins can cause toxicological changes characterized by acute death,reproductive disorders,growth disorders,and reduced resistance to infectious diseases.In addition,mycotoxins also have the risk of teratogenic,carcinogenic and mutagenic.In order to promote the healthy breeding of animals,this paper will introduce the mechanism of the abnormal intestinal function caused by feed mycotoxins.
