摘要:

霉菌毒素是食品和动物饲料中最常见的污染物,严重威胁人类和动物的健康。脱氧雪腐镰刀菌烯醇(Deoxynivalenol, DON)是镰刀菌属(Fusariums spp.)产生的次级代谢产物,广泛存在于小麦、玉米、大麦等食品加工原材料中,给畜牧业生产带来了极大经济损失。猪对DON非常敏感,给猪饲喂DON 污染日粮会导致采食量减少、增重下降和免疫功能受损等不良反应,严重时或导致死亡肠道的屏障功能是防御外源性有毒有害物质损伤机体的重要途径。在此,我们探讨了DON对肠道屏障损害包括肠道组织形态学、上皮屏障功能、肠道免疫系统、微生物菌群和肠道中短链脂肪酸的产生等方面。目前DON脱毒方法主要有物理脱毒法、化学脱毒法和生物脱毒法,其中生物脱毒法具有安全环保、特异性强、解毒效果显著等优点而备受推崇。许多饲料添加剂在DON解毒方面的潜力已得到证实。这些添加剂可通过调节 Nrf2-Keap1MAPKsNF-κB信号通路来减轻 DON 对猪的毒性作用。此外,微生物的酶降解作用可通过破坏DON的毒性基团,将DON代谢转化为毒性较小甚至无毒的物质,还有某些种类的芽孢杆菌和酵母菌具备降解DON的能力。本文结合近年来国内外相关研究进展,综述了DON对猪肠道的毒性作用及脱毒方法,对利用真菌、细菌和植物进行DON脱毒以及脱毒剂的应用进行了较为详细的阐述,可促进我们对与DON肠道毒性相关的机制的理解本文还对DON脱毒的研究进展进行了展望,并对各种保护剂的脱毒作用和应用前景进行了探讨,旨在为猪肠道健康保护提供参考,为今后安全有效的饲料添加剂的研究和开发提供新的思路

Abstract:

Mycotoxins are the most widely existing pollutants in both dietary provisions and livestock feed, and they pose a series of hazards for humans and animals.  Deoxynivalenol (DON) is a prevalent mycotoxin that is primarily produced by Fusarium spp. and commonly found in various cereal products.  Feeding swine diets contaminated with trichothecene DON can lead to major adverse effects, including reduced feed intake, diminished weight gains, and compromised immune function.  Among all animal species, swine are the most sensitive to DON.  Here we explore the disruption of gut health by DON, considering aspects such as intestinal histomorphology, epithelial barrier functions,  immune system, microflora, and short-chain fatty acid production in the intestines.  Numerous additives have been documented for their potential in the detoxification of DON.  These additives can alleviate the toxic effects of DON on pigs by modulating the Nrf2-Keap1, mitogen-activated protein kinases (MAPKs) and Nuclear factor kappa-B (NF-κB) signaling pathways.  Additionally, there are additives capable of mitigating the toxicity of DON through adsorption or biotransformation.  This update has novel potential for advancing our comprehension of the mechanisms linked to DON intestinal toxicity and facilitating the formulation of innovative strategies to mitigate the impact of DON.
